Standard And Transmission-Based Precautions - NCLEX Rn

1. A 72-year-old client in a long-term care facility has a draining wound culture positive for MRSA; the dressing is saturated, and the client reports wound pain. Vital signs: T 37.6°C (99.7°F), HR 88/min, RR 18/min, BP 132/76 mmHg, SpO2 96% on room air. What personal protective equipment (PPE) is required when the nurse enters the room to change the dressing under the indicated contact precautions?
   Answer: Gloves and gown upon room entry This question tests the application of standard and transmission-based precautions. The specific precaution relevant to this scenario is contact precautions for MRSA in a draining wound, requiring gloves and a gown upon room entry. Wearing gloves and a gown is essential for infection control to prevent direct contact with infectious material and contaminated surfaces, reducing the risk of transmitting MRSA to the nurse or other clients. Surgical mask and eye protection only (A) are inadequate without hand and clothing barriers; an N95 respirator (C) is unnecessary as MRSA is not airborne; gloves only (D) fail to protect clothing from saturation and contamination. Principles of infection prevention include breaking the chain of transmission by using barrier protections for contact-spread pathogens. Control measures emphasize consistent use of PPE when anticipating exposure to body fluids or infected sites. A general strategy for selecting appropriate precautions is to evaluate the pathogen's mode of transmission and match PPE to the anticipated level of contact or exposure.
2. A 7-year-old child in the emergency department has fever, cough, coryza, and conjunctivitis; the parent reports the child is not immunized and was exposed to measles at school. Vital signs: T 39.0°C (102.2°F), HR 120/min, RR 26/min, BP 98/60 mmHg, SpO2 96% on room air. What personal protective equipment (PPE) is required for the nurse when entering the room under the indicated precautions?
   Answer: N95 respirator (or PAPR) before room entry Measles is spread by the airborne route, and airborne precautions require the nurse to don an N95 respirator or PAPR before entering the room, so fit-tested respiratory protection put on prior to room entry is the required PPE here. The classic presentation of fever with cough, coryza, and conjunctivitis in an unimmunized child with a known exposure should trigger airborne precautions immediately rather than after diagnostic confirmation, because measles is extremely contagious and the virus remains suspended in the air. A surgical mask with gloves is the wrong level of respiratory protection because a surgical mask does not filter or seal against the small particles that carry measles, and gown and gloves alone protect against contact spread while leaving the nurse's airway completely unprotected. Assuming no PPE is needed at a six-foot distance applies droplet-precaution logic to an airborne organism, and distance does not protect against particles that travel on air currents throughout the room. Match PPE to the organism's transmission route, and put airborne protection on before you cross the threshold, not after you are in the room.
3. A nurse is about to administer an IM injection to a 26-year-old client with no isolation precautions. Vital signs are stable. What precaution should the nurse take FIRST consistent with standard precautions?
   Answer: Perform hand hygiene before preparing and administering the injection This question tests the application of standard and transmission-based precautions. The specific guideline relevant to this scenario is standard precautions for IM injections, emphasizing hand hygiene before preparation and administration. Performing hand hygiene is essential for infection control to reduce microbial load and prevent introducing pathogens at the injection site. Surgical mask and shield (B) are unnecessary without splash risks; gown (C) is not required for minimal exposure; private room (D) is not needed for routine procedures. Principles of infection prevention include clean technique for injections to avoid infections. Control measures stress hygiene as the first line of defense. A general strategy for selecting appropriate precautions is to prioritize hand hygiene for all client interactions, adding PPE based on exposure risks.
4. A nurse is preparing to suction a tracheostomy for a 60-year-old client with thick secretions and intermittent coughing; the client is not on isolation precautions. Vital signs: T 36.9°C (98.4°F), HR 86/min, RR 18/min, BP 140/84 mmHg, SpO2 92% on 4 L/min trach collar. What personal protective equipment (PPE) is required based on standard precautions for this procedure?
   Answer: Gloves and eye protection (with mask) due to risk of splashes/sprays PPE is selected by anticipated exposure, and standard precautions apply to every client regardless of diagnosis or isolation status. Tracheostomy suctioning in a client with thick secretions who coughs intermittently is a predictable source of splashes and sprays of respiratory secretions, so gloves plus eye protection with a mask are required to protect the hands and the mucous membranes of the eyes, nose, and mouth. An N95 respirator belongs to airborne precautions and is indicated when a pathogen spread by the airborne route is known or suspected, which is not the case for this client. A sterile gown and shoe covers exceed what the procedure calls for and reflect surgical practice rather than standard precautions. Believing no PPE is needed because sterile technique is used confuses two different goals, since sterile technique protects the client from contamination while PPE protects the nurse from exposure. Choose PPE by the exposure the task creates, and add transmission-based precautions only when the organism's route of spread calls for them.
5. A 29-year-old client in an urgent care clinic has fever, cough, and rhinorrhea and is diagnosed with influenza; the client is placed on droplet precautions. VS: T 38.3°C (100.9°F), HR 110/min, RR 20/min, BP 116/68 mm Hg, SpO2 96% RA. What precaution should the nurse take FIRST when transporting the client to radiology for a chest x-ray?
   Answer: Have the client wear a surgical mask during transport This question tests application of standard and transmission-based precautions during patient transport. Having the client wear a surgical mask during transport is the appropriate measure for influenza on droplet precautions, as it contains respiratory droplets at the source. This protection is essential for infection control because it prevents the spread of influenza droplets to other patients and staff in hallways and common areas during transport. An N95 respirator on the client (B) is unnecessary and uncomfortable, sterile draping (C) is excessive and unrelated to droplet transmission, and delaying transport (D) may compromise necessary care. The principles of infection prevention emphasize source control and maintaining precautions during transport. When selecting appropriate precautions for transport, focus on containing the pathogen at its source while ensuring the patient receives timely care.
6. A 45-year-old client with confirmed pertussis has paroxysmal coughing fits and post-tussive vomiting. Vital signs: T 37.7°C (99.9°F), HR 102/min, RR 24/min, BP 120/70 mmHg, SpO2 95% on room air. What personal protective equipment (PPE) is required for the nurse when entering the room under the indicated precautions?
   Answer: Surgical mask upon room entry This question tests the application of standard and transmission-based precautions. The specific precaution relevant to this scenario is droplet precautions for confirmed pertussis, requiring a surgical mask upon room entry. Wearing a surgical mask is essential for infection control to protect against large droplets expelled during paroxysmal coughing fits. N95 (B) is for airborne, not droplet; gloves and gown only (C) ignore respiratory transmission; no PPE if vaccinated (D) is unsafe as breakthrough occurs. Principles of infection prevention include masking for bacterial droplet pathogens. Control measures emphasize post-exposure prophylaxis. A general strategy for selecting appropriate precautions is to identify coughing patterns and implement droplet isolation for diseases like pertussis.
7. A 62-year-old client has Clostridioides difficile infection with frequent diarrhea and is on contact precautions. The nurse is leaving the room after assisting with toileting. The nurse should prioritize which infection control measure to reduce transmission?
   Answer: Wash hands with soap and water after removing gloves This question tests the application of standard and transmission-based precautions. The specific guideline relevant to this scenario is hand hygiene for C. difficile under contact precautions, requiring soap and water due to spore resistance. Washing hands with soap and water is essential for infection control to mechanically remove C. difficile spores that alcohol-based rubs cannot kill. Alcohol rub only (B) is ineffective against spores; double-gloving (C) does not replace hygiene; mask when leaving (D) is unnecessary without droplet risks. Principles of infection prevention include using soap for spore-forming pathogens to reduce transmission. Control measures emphasize thorough handwashing after contact with feces. A general strategy for selecting appropriate precautions is to tailor hygiene methods to the pathogen's characteristics, opting for soap over alcohol for enteric spores.
8. A 74-year-old client in a rehabilitation unit has a Foley catheter and is being assisted with perineal care; the client has no known infection and is not on isolation precautions. Vital signs: T 36.8°C (98.2°F), HR 78/min, RR 16/min, BP 126/74 mmHg, SpO2 98% on room air. What personal protective equipment (PPE) is required based on standard precautions?
   Answer: Clean gloves This question tests the application of standard and transmission-based precautions. The specific guideline relevant to this scenario is standard precautions for perineal care, requiring clean gloves when handling potentially infectious materials like urine. Wearing clean gloves is essential for infection control to prevent contact with body fluids that may harbor pathogens, even without known infections. Sterile gloves and gown (B) are unnecessary for a non-sterile procedure; surgical mask and eye protection only (C) ignore hand protection; an N95 and gown (D) exceed needs without airborne or extensive contact risks. Principles of infection prevention include universal glove use for mucous membrane contact. Control measures focus on hand hygiene before and after tasks. A general strategy for selecting appropriate precautions is to assess procedural contact with body sites and apply minimal effective PPE under standard guidelines.
9. A 19-year-old college student presents to an urgent care clinic with abrupt onset fever, myalgias, sore throat, and cough; rapid influenza A test is positive. Vital signs: T 39.1°C (102.4°F), HR 110/min, RR 22/min, BP 118/70 mmHg, SpO2 95% on room air. Which type of isolation is necessary for this client while awaiting discharge instructions?
   Answer: Droplet precautions This question tests the application of standard and transmission-based precautions. The specific precaution relevant to this scenario is droplet precautions for influenza A, which involves wearing a surgical mask when within 3-6 feet of the client. Implementing droplet precautions is essential for infection control to prevent the spread of large respiratory droplets containing the influenza virus during coughing or talking. Airborne precautions (B) are not required as influenza does not remain suspended in air; contact precautions only (C) overlook droplet transmission; protective precautions (D) are for immunocompromised clients, not infectious ones. Principles of infection prevention include isolating based on transmission mode to protect healthcare workers and others. Control measures focus on early identification of symptoms and rapid testing to guide precautions. A general strategy for selecting appropriate precautions is to assess clinical presentation and diagnostic results to determine if droplet, airborne, or contact isolation is warranted.
10. A 28-year-old client with influenza is being transported from the medical unit to radiology for a chest x-ray. Vital signs: T 38.7°C (101.7°F), HR 98/min, RR 20/min, BP 116/68 mmHg, SpO2 96% on room air. The nurse should prioritize which infection control measure during transport under droplet precautions?
    Answer: Place a surgical mask on the client during transport This question tests the application of standard and transmission-based precautions. The specific guideline relevant to this scenario is droplet precautions for influenza, requiring a surgical mask on the client during transport. Placing a surgical mask on the client is essential for infection control to contain respiratory droplets and prevent transmission to others in shared spaces. N95 on client (B) is unnecessary and may be uncomfortable; sterile sheet wrapping (C) is not standard; delaying until afebrile (D) may not be feasible for necessary tests. Principles of infection prevention include source control measures like client masking during movement. Control measures focus on minimizing exposure time and notifying receiving departments. A general strategy for selecting appropriate precautions is to plan transports with PPE that matches the isolation type, ensuring client and staff safety.
11. A 40-year-old client is admitted with suspected pulmonary tuberculosis and is placed on airborne precautions. VS: T 37.8°C (100.0°F), HR 90/min, RR 18/min, BP 124/76 mm Hg, SpO2 95% RA. What personal protective equipment (PPE) is required for the nurse to enter the room and administer oral medications?
    Answer: N95 respirator (or higher-level respirator) before room entry This question tests application of standard and transmission-based precautions for tuberculosis care. An N95 respirator or higher-level respirator is required before entering the room of a patient on airborne precautions for TB, as it filters out the small airborne particles containing TB bacteria. This protection is essential for infection control because TB particles can remain suspended in air and be inhaled, potentially causing infection in healthcare workers. A surgical mask and gown (A) provide insufficient respiratory protection, gloves only (C) don't protect against airborne transmission, and a face shield only (D) doesn't filter inhaled air. The principles of infection prevention require fit-tested respirators for airborne pathogens and proper seal checks before each use. When selecting appropriate precautions, remember that airborne precautions always require specialized respiratory protection regardless of the task being performed.
12. A 39-year-old client has a newly diagnosed draining pressure injury with heavy exudate; the wound cannot be fully covered with a dressing. Vital signs: T 37.3°C (99.1°F), HR 88/min, RR 16/min, BP 122/76 mmHg, SpO2 98% on room air. The nurse should prioritize which infection control measure?
    Answer: Initiate contact precautions and use dedicated equipment when possible Precaution type is chosen by the route the organism would take out of this client, and a draining wound with heavy exudate that cannot be contained under a dressing spreads by direct and indirect contact with that drainage. Contact precautions with gown and gloves and dedicated equipment interrupt that route by keeping drainage off hands, clothing, and shared items such as blood pressure cuffs and thermometers. Posting standard precautions only because the organism is unknown is the trap: you act on the route the drainage creates, not on a pending culture result, and uncontained exudate exceeds what standard precautions are designed to handle. Droplet precautions with a mask on the client and airborne precautions with negative pressure both target respiratory spread, and nothing in this client's presentation — respiratory rate 16, SpO2 98 percent on room air, no respiratory findings — points to a respiratory source. Match the precaution to the route: uncontained wound drainage means contact, and an unidentified organism is a reason to add precautions, never a reason to withhold them.
13. A 67-year-old client has both confirmed influenza and a positive stool test for Clostridioides difficile. Vital signs: T 38.4°C (101.1°F), HR 106/min, RR 22/min, BP 112/68 mmHg, SpO2 95% on room air. Which infection control approach is necessary while providing routine bedside care?
    Answer: Use droplet plus contact precautions (gown and gloves on entry; surgical mask on entry) and perform soap-and-water hand hygiene after care Transmission-based precautions are selected by how each organism actually travels, and when a client carries two organisms the nurse layers everything each one requires rather than choosing between them. Influenza moves in respiratory droplets, which is why a surgical mask on entry is required, and Clostridioides difficile moves by contact with spores, which is why gown and gloves on entry plus soap-and-water hand hygiene are required — alcohol-based rub does not kill spores. Masking with droplet precautions alone leaves the spore route completely unprotected during hands-on bedside care, and relying on standard precautions because the infections involve different body systems misapplies the concept: standard precautions are the baseline for every client, not a substitute for organism-specific precautions. An N95 respirator with negative pressure is the wrong precaution type here, since neither influenza during routine bedside care nor C. difficile is spread by the airborne route, and using it would still leave the contact route uncovered. Remember that transmission-based precautions follow the organism's route of spread, not the severity of the illness — and when more than one organism is present, you add the precautions together instead of picking the strictest-sounding one.
14. A 33-year-old client with a history of IV drug use is admitted with a large, draining abscess on the forearm; wound culture is pending, and the drainage is copious. Vital signs: T 37.9°C (100.2°F), HR 104/min, RR 18/min, BP 122/74 mmHg, SpO2 97% on room air. Which type of isolation is necessary while caring for this client given the uncontrolled wound drainage?
    Answer: Contact precautions This question tests the application of standard and transmission-based precautions. The specific precaution relevant to this scenario is contact precautions for a draining abscess with copious uncontrolled drainage, especially in a client with IV drug use history. Implementing contact precautions is essential for infection control to prevent transmission of potential multidrug-resistant organisms through wound exudate. Droplet (A) or airborne (D) precautions are inappropriate without respiratory symptoms; standard precautions only (B) are insufficient for uncontrolled drainage. Principles of infection prevention include isolating based on the site and nature of infection to contain spread. Control measures focus on covering wounds when possible and using PPE for contact risks. A general strategy for selecting appropriate precautions is to evaluate wound characteristics and risk factors like drug use to determine if contact isolation is needed pending cultures.
15. A nurse is caring for a 68-year-old client on contact precautions for MRSA in a wound. The nurse has completed wound care and is preparing to leave the room. What precaution should the nurse take FIRST to prevent self-contamination?
    Answer: Remove gloves before removing the gown This question tests the application of standard and transmission-based precautions. The specific guideline relevant to this scenario is the proper doffing sequence for contact precautions PPE to prevent self-contamination. Removing gloves before the gown is essential for infection control to avoid transferring contaminants from gloves to the nurse's skin or clothing. Hand hygiene before removal (B) is incorrect as PPE should be removed first; removing mask before gloves (C) risks hand contamination; keeping PPE on for charting (D) spreads pathogens outside the room. Principles of infection prevention include following a sequence that removes most contaminated items first. Control measures stress doffing inside the room followed by hand hygiene. A general strategy for selecting appropriate precautions is to adhere to PPE protocols, ensuring safe removal to maintain a clean environment.
16. A 63-year-old client with suspected tuberculosis is admitted from the emergency department to a medical unit; the nurse notes the assigned room is a standard private room without negative pressure. Vital signs: T 38.1°C (100.6°F), HR 94/min, RR 20/min, BP 128/80 mmHg, SpO2 95% on room air. The nurse should prioritize which infection control measure?
    Answer: Request transfer to an airborne infection isolation room and keep the client masked until moved Transmission-based precautions are selected by how the organism travels, and Mycobacterium tuberculosis travels in droplet nuclei that stay suspended and drift on air currents, which makes it an airborne pathogen requiring a negative-pressure airborne infection isolation room. Requesting transfer to that room and keeping the client masked until the move happens is correct because it controls the airborne particles both in transit and after arrival, and masking the source is the interim protection while the appropriate room is arranged. Droplet precautions are the wrong precaution type because they assume large droplets that fall within a few feet, which underestimates TB's true route, and contact precautions with dedicated equipment target organisms spread by touch and surfaces, not inhaled particles. Keeping the client in a standard room and simply closing the door is also the wrong environment because a closed door without negative pressure does not prevent infectious air from escaping into the corridor when the door opens. Transmission-based precautions follow the organism's route, not the severity of the illness or the convenience of the room already assigned.
17. A 48-year-old client on contact precautions for MRSA has a blood pressure cuff and stethoscope in the room labeled for single-client use. Another client on the unit needs vital signs taken urgently, and no other cuff is immediately available. What precaution should the nurse take FIRST?
    Answer: Obtain equipment dedicated to the other client or disinfect shared equipment per facility policy before use This question tests the application of standard and transmission-based precautions. The specific guideline relevant to this scenario is equipment management under contact precautions, requiring dedicated or disinfected items to prevent cross-contamination. Obtaining dedicated or disinfected equipment is essential for infection control to avoid transmitting MRSA to another client via shared items. Using the cuff without cleaning (B or D) risks spread; placing the other on precautions (C) is unnecessary if cleaned. Principles of infection prevention include disinfecting non-dedicated equipment between uses. Control measures focus on labeling and cleaning protocols. A general strategy for selecting appropriate precautions is to assess equipment sharing risks and ensure disinfection per policy for isolation clients.
18. A 70-year-old hospitalized client has shingles with vesicular lesions on the face and scattered lesions on the trunk; the client is receiving high-dose steroids for COPD exacerbation. Vital signs: T 37.8°C (100.0°F), HR 90/min, RR 20/min, BP 136/82 mmHg, SpO2 93% on 2 L/min nasal cannula. Which type of isolation is necessary for this client?
    Answer: Airborne and contact precautions This question tests the application of standard and transmission-based precautions. The specific precaution relevant to this scenario is airborne and contact precautions for disseminated shingles in an immunocompromised client receiving steroids. Implementing combined precautions is essential for infection control to prevent both airborne dissemination of varicella-zoster virus and contact transmission from vesicular lesions. Droplet only (B) or contact only (C) miss one transmission mode; standard only (D) is insufficient for active dissemination. Principles of infection prevention include layering precautions for viruses with multiple transmission routes in vulnerable clients. Control measures focus on isolating until lesions crust to reduce infectivity. A general strategy for selecting appropriate precautions is to evaluate lesion distribution and immune status to determine if airborne plus contact is required over contact alone.
19. A 66-year-old client is 1 day post-op after a total hip arthroplasty and has a closed incision with a dry dressing; history includes hypertension. VS: T 36.8°C (98.2°F), HR 78/min, RR 16/min, BP 130/76 mm Hg, SpO2 97% RA. What precaution should the nurse take FIRST before emptying the client's urinary drainage bag?
    Answer: Perform hand hygiene and apply clean gloves This question tests application of standard and transmission-based precautions for routine post-operative care. Standard precautions including hand hygiene and clean gloves are appropriate when handling body fluids like urine, regardless of the patient's infection status. This protection is essential for infection control because it prevents transmission of bloodborne pathogens and other microorganisms that may be present in urine. A surgical mask (A) is unnecessary as no respiratory transmission risk exists, an N95 respirator (C) is excessive for this task, and sterile equipment (D) is not required for emptying drainage bags. The principles of infection prevention emphasize using standard precautions for all patients when contact with body fluids is anticipated. When selecting appropriate precautions, consider the specific task being performed and whether contact with blood or body fluids is expected.
20. A 46-year-old client is admitted to a medical unit with suspected pulmonary tuberculosis after 3 weeks of cough, night sweats, weight loss, and hemoptysis; a chest x-ray shows upper-lobe infiltrates. Vital signs: T 38.2°C (100.8°F), HR 96/min, RR 20/min, BP 124/78 mmHg, SpO2 94% on room air. What precaution should the nurse take FIRST when preparing to enter the room?
    Answer: Don an N95 respirator (or PAPR) before room entry and ensure the client is in an airborne infection isolation room This question tests the application of standard and transmission-based precautions. The specific precaution relevant to this scenario is airborne precautions for suspected pulmonary tuberculosis, requiring an N95 respirator or PAPR and placement in an airborne infection isolation room. Donning an N95 respirator before entry is essential for infection control to filter out small airborne particles containing Mycobacterium tuberculosis during client coughing or breathing. Gloves and gown for skin contact (B) are incorrect as TB is not spread by contact; surgical mask and face shield (C) protect against droplets but not airborne particles; immediate transport without isolation (D) risks exposure to others. Principles of infection prevention include using respiratory protection and negative-pressure rooms for airborne pathogens. Control measures emphasize prompt isolation for suspected cases to minimize transmission. A general strategy for selecting appropriate precautions is to consider symptoms like cough and hemoptysis alongside diagnostic indicators to initiate airborne isolation promptly.
