Question 1: Standard Precautions — When to Use Them
A nurse is preparing to care for a client newly admitted to a medical-surgical unit. The client has no confirmed or suspected infection. Which infection-control action should the nurse implement?
The correct action is to use standard precautions because they are required for every client, even when no infection has been diagnosed.
The clinical reasoning is infection-control safety: the nurse assumes that blood, body fluids, secretions, excretions, non-intact skin, and mucous membranes may carry microorganisms.
Standard precautions help break the chain of infection by using hand hygiene, appropriate PPE, safe injection practices, sharps safety, and proper handling of contaminated equipment.
Clinical pearl: do not wait for laboratory confirmation before protecting the client, the nurse, and others. A client can transmit microorganisms before results are available or before infection is recognized.
The tempting distractor is using airborne precautions for all admissions, but airborne precautions are only for specific suspected or confirmed infections such as tuberculosis, measles, or varicella.
Question 2: Hand Hygiene After C. difficile Care
The nurse assists a client with Clostridioides difficile infection to use the bedside commode and removes gloves after providing care. Which hand hygiene action is most appropriate?
The correct action is to wash hands with soap and water. C. difficile can form spores, and alcohol-based hand sanitizer does not reliably remove or destroy those spores.
The clinical reasoning is infection control: after contact with stool or care for a client with C. difficile, the priority is to prevent transmission to other clients, staff, and surfaces.
Soap, water, friction, and rinsing work together to mechanically remove spores from the hands. Gloves lower the risk of contamination, but hand hygiene is still required after gloves are removed.
Clinical pearl: For suspected or confirmed C. difficile, use contact precautions and wash hands with soap and water after care, especially after toileting or perineal care.
The most tempting wrong answer is alcohol-based sanitizer because it is commonly used in health care, but it is not acceptable as the only hand hygiene method in this situation.
Question 3: Airborne Precautions — Tuberculosis
A client is admitted with suspected pulmonary tuberculosis and is placed on airborne precautions. Which personal protective equipment should the nurse wear before entering the room?
The correct answer is N95 respirator. Suspected pulmonary tuberculosis requires airborne precautions, so the nurse must wear a fit-tested N95 respirator or higher-level respirator before entering the room.
The clinical reasoning is infection-control based: identify the mode of transmission, then choose PPE that blocks that route. Tuberculosis spreads through tiny airborne droplet nuclei that can remain suspended in the air and be inhaled.
- Nurse: wears an N95 respirator or higher-level respirator.
- Client: should be in a negative-pressure airborne infection isolation room with the door closed.
- Transport: place a surgical mask on the client if transport is necessary.
The most tempting distractor is a surgical mask, but that is not enough protection for the nurse because it does not reliably filter airborne tuberculosis particles. A surgical mask is used for droplet protection or source control, not as the nurse’s primary protection for airborne tuberculosis.
Question 4: Contact Precautions — MRSA
A nurse is preparing to perform wound care for a client with methicillin-resistant Staphylococcus aureus (MRSA) in a draining wound. Which personal protective equipment (PPE) should the nurse apply before providing care?
The correct answer is gloves and gown. MRSA in a draining wound is managed with contact precautions because the organism can spread through wound drainage, contaminated hands, clothing, equipment, and surfaces.
The clinical reasoning is to match the transmission route with the correct PPE. Since MRSA wound drainage spreads by contact, the nurse protects the hands with gloves and the uniform with a gown before wound care.
MRSA is a strain of Staphylococcus aureus that is resistant to many beta-lactam antibiotics, but the isolation decision is based on how it spreads, not on the drug resistance itself.
Clinical pearl: add eye or face protection if wound irrigation or drainage could splash. Do not rely on a mask or respirator alone for a draining wound.
The most tempting distractor is an N95 respirator, but that is for airborne infections such as tuberculosis, measles, and varicella—not routine MRSA wound care.
Question 5: Droplet Precautions — Meningococcal Meningitis
A client admitted with suspected meningococcal meningitis is placed on infection-control precautions. Which personal protective equipment should the nurse wear when entering the client's room?
The correct PPE is a surgical mask because meningococcal meningitis is spread by respiratory droplets.
The clinical reasoning is infection-control based: first identify the organism as a droplet-spread infection, then select the PPE that blocks droplets from reaching the nurse's nose and mouth.
Neisseria meningitidis can be spread when an infected person coughs, sneezes, or talks, sending large respiratory droplets over short distances.
The key clinical pearl is that clients with suspected or confirmed meningococcal meningitis need standard plus droplet precautions, typically until they have received effective antibiotic therapy for the recommended period per facility policy.
The most tempting distractor is the N95 respirator, but an N95 is for airborne infections such as tuberculosis, measles, and varicella—not routine meningococcal droplet precautions.
Question 6: Needlestick Injury — First Action
A nurse administers an injection and sustains a needlestick injury from the used needle. Which action should the nurse take first?
The correct first action is to wash the area with soap and water. A used needle can expose the nurse to bloodborne pathogens, so immediate first aid comes before reporting or documentation.
The priority framework is safety first: stop the exposure and clean the site, then follow the facility’s exposure protocol. Washing helps remove blood or body fluid from the skin surface and decreases local contamination.
- First: Wash the puncture site with soap and water.
- Next: Report the exposure to the appropriate supervisor or employee health service.
- Then: Complete required documentation and participate in post-exposure evaluation.
Do not delay first aid to look up the client’s infection history or complete paperwork. Employee health follow-up is important, but it occurs after the wound is cleaned.
Question 7: Sharps Disposal Safety
A nurse observes a student nurse completing a capillary blood glucose check and preparing to discard the used lancet. Which student nurse action requires correction?
The action that requires correction is discarding the used lancet in a regular trash bag. A lancet is a contaminated sharp and must be placed in an approved puncture-resistant sharps container.
This question uses the safety and infection control framework: the nurse must evaluate which action creates a risk for injury or bloodborne pathogen exposure.
The key mechanism is simple: a sharp object contaminated with blood can puncture skin and expose another person to pathogens such as hepatitis B, hepatitis C, or HIV.
Clinical pearl: dispose of sharps immediately, at the point of use, and avoid unnecessary handling. Never place used sharps in regular waste.
The tempting distractor is avoiding recapping, but that is actually correct practice because recapping brings the hand close to the contaminated sharp and increases needlestick risk.
Question 8: Fire Safety — RACE Protocol
A nurse notices smoke coming from a trash can in a client’s room and immediately moves the client to a safe location. Which action should the nurse take next?
The correct next action is to activate the fire alarm. The client has already been moved away from danger, so the nurse has completed the first step of the fire response sequence.
Use the RACE framework for a fire in a health care setting:
- Rescue clients in immediate danger.
- Alarm by activating the fire alarm system.
- Contain the fire and smoke by closing doors.
- Extinguish/Evacuate if safe and directed by facility policy.
Fire grows when heat, fuel, and oxygen are present. Opening windows can add oxygen and worsen the fire or spread smoke, so that is unsafe.
The most tempting distractor is extinguishing the fire first, but that comes later in the sequence and only if the fire is small and the nurse can do so safely. Never delay alarm activation during an active fire.
Question 9: Restraint Safety
While making rounds, the nurse observes that a client’s wrist restraints are secured to the movable side rails of the bed. Which action should the nurse take?
The correct action is to secure the restraints to the bed frame. Restraints must not be tied to side rails because side rails move.
This is a safety question. The nurse must take the action that prevents injury right away.
If a side rail is raised or lowered while a restraint is tied to it, the client’s wrist can be pulled suddenly. This can cause skin injury, impaired circulation, nerve compression, or joint injury.
A key clinical pearl is: restraints should be used only when necessary, with the least restrictive method, and the nurse must reassess circulation, skin, comfort, and continued need according to policy.
The tempting distractor is leaving the restraint in place if it is not too tight. That is unsafe because the problem is not only tightness—the problem is the wrong attachment point.
Question 10: Fall Prevention
A hospitalized client is identified as being at high risk for falls. Which intervention is appropriate for the nurse to include in the client’s plan of care?
The correct intervention is to keep the bed in the lowest position. This reduces the distance the client could fall and makes transfers safer if the client tries to get out of bed.
This question uses the safety priority: prevent injury before it occurs. For a high fall-risk client, the nurse should remove hazards and make it easy for the client to call for help.
- Keep the bed low and locked.
- Keep the call light and personal items within reach.
- Keep the floor and bedside area free of clutter.
- Use nonskid footwear and alarms when appropriate.
The key mechanism is simple: falls often occur during transfers or unassisted ambulation, and a lower bed decreases impact and improves stability. A high bed, clutter, or inaccessible call light makes a preventable fall more likely.
The most tempting distractor is raising the bed because staff often raise beds while providing care. That is only temporary; the bed must be lowered again when care is finished.
Question 11: Varicella — Combined Airborne and Contact Precautions
A child is admitted with fever and a generalized pruritic vesicular rash. The nurse notes lesions in different stages of healing. Which transmission-based precautions should the nurse initiate?
The correct answer is airborne and contact precautions. Fever with vesicular lesions in different stages of healing is a classic cue for varicella, and the nurse must select precautions that match how the infection spreads.
Varicella-zoster virus spreads in two major ways:
- Airborne: tiny infectious particles can remain suspended in the air.
- Contact: direct contact with vesicle fluid or contaminated items can transmit the virus.
The infection-control framework is simple: match the route of transmission to the correct precautions. For varicella, that means an airborne infection isolation room, respiratory protection such as an N95 respirator, and contact PPE such as gown and gloves.
Clinical pearl: a vesicular rash with lesions in different stages of healing should immediately raise concern for varicella until ruled out.
The most tempting distractor is contact precautions only, because the rash has open lesions. That is incomplete because varicella is also airborne.
Question 12: PPE Donning Sequence
A nurse is preparing to enter the room of a client on isolation precautions that require a gown, mask, goggles, and gloves. In which order should the nurse don the required personal protective equipment?
The correct order is gown, mask, goggles, gloves. This sequence follows the standard PPE donning process and creates the safest protective barrier before entering an isolation room.
This is a take-action safety question: the nurse must choose the correct procedure to reduce transmission of microorganisms. PPE works by interrupting the chain of infection, especially the spread of organisms by contact, droplets, or airborne particles.
The key idea is protective layering. The gown covers clothing and exposed skin first, the mask protects the nose and mouth, goggles protect the eyes, and gloves go on last to cover the gown cuffs.
Clinical pearl: gloves are donned last but are often removed first during doffing because they are usually the most contaminated item.
The most tempting error is putting gloves on first. Gloves feel like the main protection, but applying them early can contaminate them while adjusting the rest of the PPE and leaves the gown cuffs unprotected.
Question 13: PPE Doffing Sequence — Contact Precautions
A nurse is providing care for a client on contact precautions. The nurse’s gown and gloves are visibly contaminated after care. Which personal protective equipment should the nurse remove first?
The correct answer is to remove the gown and gloves together using proper doffing technique. These items are usually the most contaminated during contact precautions, so they should be removed in a way that contains the contaminated surfaces.
The clinical reasoning is safety and infection control: remove the dirtiest PPE first while avoiding contact between contaminated surfaces and the nurse’s skin, uniform, or face.
Microorganisms can spread by direct contact from contaminated PPE to the nurse’s hands, clothing, equipment, or the environment. Rolling the gown inward and peeling the gloves off with it helps trap contamination inside.
Key pearl: after removing contaminated PPE, perform hand hygiene immediately. If a mask or respirator is worn, it is generally removed last, often after leaving the room, because it protects the mouth and nose.
The tempting distractor is facial PPE, such as goggles or a mask. These are not removed first because touching the face area before removing heavily contaminated gown and gloves increases the risk of self-contamination.
Question 14: CLABSI Prevention — Central Line Hub Care
A nurse is preparing to access a client's central venous catheter for intravenous medication administration. Which action should the nurse take to reduce the risk for central line-associated bloodstream infection?
The correct action is to scrub the hub with friction and allow it to dry before accessing the line. The catheter hub is a common place for microorganisms to enter a central venous catheter and travel directly into the bloodstream.
This question uses the safety and infection-control framework: prevent contamination before it reaches the client. The nurse should disinfect the needleless connector before every access and maintain the closed system whenever possible.
The key mechanism is simple: friction removes organisms from the hub, the antiseptic kills microbes, and drying time allows the antiseptic to work fully. Accessing a wet or unclean hub can introduce pathogens into the central line.
Clinical pearl: A central line gives microorganisms a direct path to the bloodstream, so small breaks in aseptic technique can cause serious infection.
The most tempting wrong action is flushing first, but that is unsafe because it may push hub contamination into the catheter instead of removing it.
Question 15: CAUTI Prevention (Select All That Apply)
The nurse is caring for a client who has an indwelling urinary catheter. Which actions should the nurse take to reduce the risk for catheter-associated urinary tract infection (CAUTI)? Select all that apply.
The correct actions are to keep the drainage bag below bladder level, maintain a closed drainage system, and secure the catheter. These actions reduce CAUTI risk by preventing urine backflow, limiting bacterial entry, and decreasing urethral trauma.
The clinical reasoning is infection prevention: protect the urinary tract from microorganisms and remove unnecessary infection risks. Bacteria can enter through catheter movement, contaminated tubing connections, or urine flowing backward from the bag toward the bladder.
The most important clinical pearl is: do not break the closed system unless clinically necessary. Disconnecting the catheter from the tubing for routine cleaning is a common but unsafe misconception because it creates a direct contamination route.
Indwelling catheters should also be used only when there is a valid clinical indication. Convenience for staff is never an appropriate reason for catheter insertion.
Question 16: UAP Scope of Practice — Oxygen Safety
A client states to the unlicensed assistive personnel (UAP), “I can’t breathe.” Which UAP action requires correction by the nurse?
The correct answer is the UAP action that involves starting oxygen therapy independently. On the NCLEX, oxygen is treated as a medication, so it requires a nurse’s assessment and a provider order, standing order, or approved emergency protocol.
This question tests delegation and scope of practice. The UAP may assist with simple, noninvasive actions, but the nurse is responsible for assessment, interpretation, and treatment decisions.
Dyspnea is an ABC priority because breathing problems can quickly lead to hypoxemia. The safest UAP actions are to notify the nurse immediately, place the client in a position that supports breathing, and obtain pulse oximetry only if facility policy allows.
Clinical pearl: A report of “I can’t breathe” should never be ignored or handled independently by assistive personnel. It requires prompt nurse assessment.
The most tempting distractor is checking pulse oximetry. That action may be appropriate if permitted, but obtaining data is different from independently starting a treatment.
Question 17: Insulin Pen Safety
While preparing insulin for a hospitalized client, the nurse finds an insulin pen labeled with another client’s name in the client’s medication drawer. Which action is safest?
The safest action is to not use the pen and obtain the correct insulin pen for the client. Insulin pens are single-client devices, even when a new needle is attached.
This question uses a safety and infection-control framework: stop the unsafe action before giving the medication. The nurse must protect the client from both a medication error and possible exposure to bloodborne pathogens.
The key mechanism is backflow contamination. During use, microscopic blood or tissue fluid can enter the pen cartridge, so the inside of the pen may be contaminated even if the needle is changed.
Clinical pearl: a new needle or an alcohol swab does not make a shared insulin pen safe. If the pen is labeled for someone else, it must not be used.
The most tempting wrong answer is using a new needle. That sounds clean, but it only changes the external needle; it does not remove possible contamination inside the pen.
Question 18: Vancomycin Infusion Safety
A client has a prescription for intravenous vancomycin for a serious bacterial infection. Which nursing action is safest when administering this medication?
The safest action is to infuse IV vancomycin at a controlled rate over at least 60 minutes, using an infusion pump. This prevents the medication from entering the bloodstream too quickly.
The clinical reasoning is simple medication safety: when giving a high-risk IV medication, the nurse follows the correct route, dilution, and infusion rate to prevent harm.
Rapid vancomycin infusion can cause a vancomycin infusion reaction, formerly called red man syndrome. This is a histamine-mediated reaction that can cause flushing, redness, itching, and hypotension.
Clinical pearl: flushing or sudden hypotension during a vancomycin infusion should prompt the nurse to suspect the infusion is running too quickly and assess the client immediately.
The most tempting wrong answer is giving it as an IV push, but vancomycin is not administered as a rapid bolus because that greatly increases the risk of an infusion reaction.
Question 19: Sterile Field — Contamination
The nurse prepares a sterile field before inserting an indwelling urinary catheter for an adult client. Which action by the nurse contaminates the sterile field?
The correct answer is the action in which the nurse reaches over the sterile field. The nurse’s arm, sleeve, or clothing is not sterile, and microorganisms can fall onto sterile supplies even without direct contact.
This question uses the clinical judgment step of analyzing cues: the nurse must decide which action breaks surgical asepsis. Sterile technique is used to prevent microorganisms from entering normally sterile body areas, such as the bladder during urinary catheter insertion.
A sterile field is considered contaminated if it is reached over, touched by an unsterile object, becomes wet, falls below waist level, or is out of the nurse’s view.
Clinical pearl: the outer 1-inch border of a sterile wrapper is not sterile. Touching that border while opening the kit is allowed, but sterile supplies should not be placed on it.
The tempting distractor is opening the first flap away from the body. That is actually correct practice because it prevents the nurse from reaching across the sterile field.
Question 20: Live Vaccines and Immunocompromised Clients
The nurse is reviewing prescribed immunizations for a client with advanced HIV infection and a very low CD4 count. Which vaccine should the nurse question before administration?
The correct answer is varicella vaccine because it is a live attenuated vaccine. In a client with advanced HIV and a very low CD4 count, a live vaccine can potentially cause infection because the immune system may not control the weakened organism.
The clinical reasoning is analyze cues: the nurse connects the cue “severely immunocompromised” with the vaccine type “live attenuated.” The safe nursing action is to question the order and clarify with the provider before giving it.
Live attenuated vaccines contain organisms that can still replicate. Most healthy immune systems control them, but severe immunosuppression increases the risk for vaccine-associated disease.
Clinical pearl: Before giving vaccines, screen for immunosuppression, pregnancy, allergies, and prior severe vaccine reactions. Live vaccines require extra caution in clients with severe immunocompromise.
The tempting distractors are inactivated or recombinant vaccines. Inactivated influenza, pneumococcal, and hepatitis B vaccines do not contain live organisms and are generally safe and recommended for many clients with HIV.
Question 21: Hepatitis C — Transmission and Client Teaching
A nurse is providing discharge teaching to a client newly diagnosed with hepatitis C virus infection. Which client statement indicates an understanding of how to prevent transmission?
The correct answer is the statement about not sharing razors or personal items that may contain blood. Hepatitis C is a bloodborne infection, so prevention focuses on avoiding contact with infected blood.
This question uses the evaluate-outcomes step of clinical judgment because the nurse must decide whether the teaching was effective based on the client’s statement.
HCV can survive in small amounts of blood on personal items, injection equipment, or other contaminated objects. Even tiny blood exposure can transmit infection.
Clinical pearl: HCV is not spread by coughing, casual contact, or sharing cooked food. Teach clients to avoid sharing razors, toothbrushes, needles, and any item that may be contaminated with blood.
The tempting isolation-related answer is wrong because hepatitis C does not require airborne isolation. Airborne precautions are for infections spread through tiny respiratory particles, not bloodborne viruses.
Question 22: Antibiotic Adherence — Client Teaching
A client being treated with antibiotics for pneumonia tells the nurse, “I stopped taking them after 3 days because I felt better.” Which response by the nurse is best?
The correct response is to teach the client to take antibiotics exactly as prescribed and not stop early without contacting the provider. Feeling better does not always mean the infection is fully treated.
This question uses the NCJMM generate-solutions step: the nurse must choose the safest teaching response to correct unsafe medication use.
Antibiotics reduce or kill bacteria, but stopping too soon may leave surviving organisms behind. Those organisms can multiply again, causing relapse, and repeated incomplete exposure can contribute to antibiotic resistance.
Clinical pearl: clients should never save leftover antibiotics or take them only when symptoms are severe. Antibiotics work best when taken on the prescribed schedule to maintain effective drug levels.
The tempting distractor is stopping when the fever is gone. Fever may improve early, but symptom improvement is not the same as complete infection control.
Question 23: Infection Control Triage — Suspected Tuberculosis
Four clients are waiting in a shared emergency department triage area. From an infection-control perspective, which client should the nurse assess first?
The priority client is the one with persistent cough, weight loss, and night sweats because these are classic warning signs of pulmonary tuberculosis.
This question uses an infection-control priority framework: identify the client most likely to transmit a serious infection to others and isolate that client quickly.
Tuberculosis spreads by airborne droplet nuclei, which can remain suspended in the air and be inhaled by others. A coughing client with possible TB in a shared waiting area is a risk to clients, staff, and visitors.
- Place a mask on the client for source control.
- Move the client to an airborne infection isolation room when available.
- Staff should use a fit-tested N95 respirator or equivalent protection.
The tempting distractor is the client with a nosebleed who takes aspirin because bleeding can be concerning. However, the question asks specifically about infection control, and a nosebleed does not pose the same transmission risk as suspected TB.
Question 24: Pregnant Healthcare Worker — Assignment Safety
The charge nurse is reviewing client assignments for a pregnant nurse who has no documented evidence of varicella immunity. Which assignment should the charge nurse change?
The assignment involving active varicella should be changed. A pregnant nurse without documented immunity should not be assigned to a client with chickenpox when another safe assignment is available.
This is a safety and infection control question. The key cue is not pregnancy by itself; it is pregnancy combined with no evidence of varicella immunity and exposure to an infectious client.
Varicella-zoster virus spreads through airborne particles and contact with skin lesions. In pregnancy, primary varicella infection can cause serious maternal complications, especially varicella pneumonia, and can harm the fetus.
Clinical pearl: Pregnant staff who are not immune should avoid caring for clients with active varicella or disseminated herpes zoster and should notify occupational health if exposure occurs.
The other diagnoses—heart failure, hypertension, and osteoarthritis—may require nursing care, but they are not communicable infections and do not pose a varicella-specific risk.
Question 25: Neutropenic Precautions (Select All That Apply)
A hospitalized adult client has an absolute neutrophil count (ANC) of 350/mm³. Which interventions should the nurse implement? Select all that apply.
An ANC of 350/mm³ indicates severe neutropenia, which means the client has very few neutrophils available to fight bacterial and fungal infections.
The correct interventions are strict hand hygiene, screening visitors for illness, avoiding raw fruits and vegetables unless facility policy allows, and monitoring temperature closely. These actions follow the safety and infection-control framework: prevent exposure first and detect infection early.
Neutrophils are a major part of the body’s first-line immune defense. When neutrophils are very low, the client may not show typical signs such as pus, redness, or swelling.
Clinical pearl: in a neutropenic client, fever may be the only early sign of sepsis and should be reported promptly.
The most tempting distractor is a negative-pressure room, but that is for airborne isolation. Neutropenic precautions protect the client from organisms in the environment; they do not require negative pressure.
Question 26: C. difficile — Room and Toileting Safety
A client with suspected Clostridioides difficile infection is admitted with frequent watery diarrhea and is assigned to a semi-private room. Which infection-control action is most appropriate?
The correct action is to place the client on contact precautions and provide a dedicated commode, with a private room if available. This prevents fecal contamination of shared surfaces and reduces spread to other clients.
The clinical reasoning is infection-control safety: identify the mode of transmission, then choose precautions that block that route. C. difficile spreads mainly by the fecal-oral route through spores on hands, equipment, toilets, and environmental surfaces.
Key pearl: C. difficile spores are difficult to kill and can persist in the environment. After care, hand hygiene should be performed with soap and water because alcohol-based sanitizer does not reliably eliminate spores.
The tempting distractor is using alcohol-based sanitizer while keeping the client in a semi-private room. That misses two major safeguards: preventing exposure of a roommate and removing spores with soap-and-water handwashing.
Question 27: Fall Risk Recognition
The nurse is reviewing fall-risk factors for several adult clients on a medical-surgical unit. Which client has the greatest risk for falls?
The correct answer is the older client receiving IV furosemide who reports dizziness when standing. This client has multiple fall-risk cues occurring at the same time.
The priority framework is safety: the nurse identifies which client is most likely to experience injury if precautions are not started. Dizziness with position changes is an immediate warning sign for a fall.
Furosemide is a loop diuretic that increases urine output. This can lower circulating fluid volume and contribute to orthostatic hypotension, especially when moving from lying or sitting to standing.
A key clinical pearl: reports of dizziness on standing should be treated as a fall-risk red flag until proven otherwise. The nurse should assist with ambulation, encourage slow position changes, keep the call light within reach, and follow facility fall-prevention protocols.
The tempting distractor is the client with controlled hypertension. Hypertension or antihypertensive therapy can be related to fall risk in some cases, but this option does not include active dizziness or other high-risk cues.
Question 28: Mucous Membrane Exposure — Eye Splash
During suctioning, respiratory secretions splash into the nurse’s eyes. Which action should the nurse take first?
The correct first action is to flush the eyes immediately with water or saline. This removes and dilutes potentially infectious material from the mucous membranes before any reporting or paperwork.
This question uses the priority framework of safety and decontamination first. When exposure is actively present on the body, the nurse first stops the exposure by irrigating the affected area.
The key mechanism is simple: infectious body fluid on the conjunctiva can contact mucous membrane tissue. Prompt irrigation lowers the amount of contaminant and decreases contact time.
- First: flush the exposed eyes.
- Next: report the exposure and follow employee health/post-exposure protocol.
- Then: complete required documentation.
The most tempting distractor is reporting to employee health, because that is required. It is wrong as the first step because decontamination must not be delayed.
Question 29: Fentanyl Patch Disposal
The nurse removes a used fentanyl transdermal patch from a client receiving opioid analgesia. Which action should the nurse take to dispose of the patch safely?
The correct action is to fold the patch with the adhesive sides together and dispose of it according to the facility’s controlled-substance policy. A used fentanyl patch can still contain enough opioid to cause accidental overdose or be diverted.
This is a medication safety question. The safest action is the one that prevents accidental exposure, prevents drug diversion, and follows controlled-substance documentation requirements.
Fentanyl is a potent opioid analgesic. Residual drug in the patch can be absorbed through skin contact and may cause life-threatening respiratory depression, especially in opioid-naive persons, children, or pets.
Clinical pearl: “Used” does not mean “empty” for transdermal opioid patches. Treat every removed fentanyl patch as active medication until it is disposed of correctly.
The most tempting wrong answer is to place the patch in a trash can, but regular trash is unsecured and unsafe for controlled-substance waste.
Question 30: Recognizing Unsafe Practice — Priority Intervention
While making rounds, the nurse observes several safety and infection-control practices on the unit. Which observed action requires immediate intervention?
The priority concern is the visitor entering a tuberculosis isolation room while wearing only a surgical mask. Tuberculosis is spread by airborne droplet nuclei, so a person entering the room needs appropriate respiratory protection, such as a fit-tested N95 respirator or higher-level respirator according to facility policy.
This question uses a safety and infection-control priority framework: identify which observed action creates the most immediate risk of harm or disease transmission. The incorrect tuberculosis PPE creates an immediate exposure risk and requires the nurse to intervene right away.
The key mechanism is that Mycobacterium tuberculosis can remain suspended in the air in very small particles after a client coughs, speaks, or sneezes. A surgical mask helps contain large droplets from the wearer, but it does not adequately protect the wearer from inhaling airborne particles.
Clinical pearl: airborne precautions require an airborne infection isolation room when available, the door kept closed, and appropriate respirator use for those entering the room.
The tempting distractor is handwashing after C. difficile care, but soap and water is the correct choice because it removes spores better than alcohol-based hand rub.
Key Takeaways: NCLEX Safety and Infection Control
- Standard precautions apply to every client regardless of diagnosis — blood, body fluids, non-intact skin, and mucous membranes are always treated as potentially infectious.
- C. difficile spores resist alcohol-based hand sanitizer — always use soap and water hand hygiene after providing care to a client with C. difficile.
- Tuberculosis requires an N95 respirator (airborne precautions) in a negative-pressure room — a surgical mask is never sufficient for TB.
- Varicella requires both airborne AND contact precautions — N95, gown, and gloves are all required.
- Meningococcal meningitis requires droplet precautions — a surgical mask within 3 feet of the client.
- MRSA requires contact precautions — gloves and gown before entering the room or providing care.
- PPE donning sequence: gown → mask → goggles → gloves. Gloves go on last to cover gown cuffs.
- After a needlestick or eye splash, the first action is always immediate decontamination (soap and water for needlestick; water or saline irrigation for eye splash) — report and document after.
- Sharps — including used lancets — must always go directly into an approved sharps container, never into regular trash.
- RACE fire sequence: Rescue → Alarm → Contain → Extinguish. After removing the client, activate the alarm before attempting to extinguish the fire.
- Restraints must be secured to the bed frame — never to side rails, which can injure the client when the rails are moved.
- Insulin pens are client-specific and must never be shared between clients, even with a new needle attached.
- IV vancomycin must be infused over at least 60 minutes to prevent vancomycin infusion reaction (flushing, hypotension).
- CAUTI prevention: keep the drainage bag below bladder level, maintain a closed system, secure the catheter — and insert only when clinically indicated.
- CLABSI prevention: scrub the hub with friction and let it dry completely before accessing the central line.
- Neutropenic precautions: strict hand hygiene, screen visitors, avoid fresh flowers and raw produce, monitor temperature — negative-pressure rooms are not used for neutropenic clients.
- Live vaccines (varicella, MMR, live-attenuated flu) require careful review and are generally contraindicated in severely immunocompromised clients.
- A used fentanyl patch retains residual drug — fold adhesive sides together and dispose according to controlled-substance policy with a witness.
