76Question
A nurse has finished wound care for a client on contact and droplet precautions and is wearing gloves, a gown, eye protection and a surgical mask. Which item does the nurse remove last?
- Gloves
- Gown
- Eye protection
- Mask
Show the answer and explanation
Answer: D. Mask
Topic: doffing order
Protective equipment is removed from most contaminated to least contaminated, and the mask is taken off last so the nurse's mucous membranes stay protected until the other contaminated items are off. The mask is handled only by its ties or ear loops, and hand hygiene follows immediately.
Why the others are wrong
- A – Gloves are the most contaminated item and are removed first, alone or together with the gown.
- B – The gown is removed early, with or right after the gloves, by rolling it inside out away from the body.
- C – Eye protection is removed after gloves and gown but before the mask, handling only the earpieces or headband.

77Question
A client with a wound infected with methicillin-resistant Staphylococcus aureus (MRSA) is being admitted, and no private room is available. With which client is it most appropriate to place this client?
- A client who had a total hip replacement yesterday
- A client with a MRSA skin infection and no other infection
- A client receiving chemotherapy whose neutrophil count is low
- A client with diarrhea caused by Clostridioides difficile
Show the answer and explanation
Answer: B. A client with a MRSA skin infection and no other infection
Topic: room assignment and cohorting
When a single room is not available, a client on contact precautions is cohorted with another client who is infected or colonized with the same organism and has no other infection. This keeps the organism from reaching a client who does not already carry it.
Why the others are wrong
- A – A fresh surgical wound and a new joint implant make this client highly vulnerable to MRSA infection.
- C – A neutropenic client is immunocompromised and must be protected from any infected roommate.
- D – Both clients need contact precautions, but the organisms differ, so each could acquire the other's infection.

78Question
A nurse is observing a nursing student set up a sterile field for a dressing change. Which actions by the student maintain surgical asepsis?
Select all that apply.
- Opens the outermost flap of the sterile package away from the body first
- Turns away from the field briefly to reach supplies on the counter behind
- Treats the outer 1 inch (2.5 cm) border of the sterile drape as unsterile
- Keeps sterile gloved hands above waist level and in sight
- Leaves the field in place after a few drops of saline soak through the drape to the table
Show the answers and explanation
Answers: A, C and D.
- A – Opens the outermost flap of the sterile package away from the body first
- C – Treats the outer 1 inch (2.5 cm) border of the sterile drape as unsterile
- D – Keeps sterile gloved hands above waist level and in sight
Topic: sterile field principles
Opening the first flap away from the body avoids reaching over the field later, the outer border of a sterile field is considered contaminated, and sterile items are kept above the waist and in view. A sterile field that is out of sight or that becomes wet on an unsterile surface is considered contaminated.
Why the others are wrong
- B – A sterile field that is out of the nurse's line of vision cannot be guaranteed sterile and is considered contaminated.
- E – Moisture wicks microorganisms from the unsterile table through the drape (strike-through), so the field must be replaced.

79Question
A client is admitted with profuse watery diarrhea, and a stool test is positive for Clostridioides difficile. Which measures does the nurse include in the plan of care?
Select all that apply.
- Wear a gown and gloves on every entry to the room
- Wash hands with soap and water after removing gloves
- Wear a fit-tested N95 respirator in the room
- Keep a stethoscope and thermometer in the room for this client only
- Ask that the room be cleaned with a sporicidal (bleach-based) disinfectant
- Place the client in a negative-pressure room with the door closed
Show the answers and explanation
Answers: A, B, D and E.
- A – Wear a gown and gloves on every entry to the room
- B – Wash hands with soap and water after removing gloves
- D – Keep a stethoscope and thermometer in the room for this client only
- E – Ask that the room be cleaned with a sporicidal (bleach-based) disinfectant
Topic: C. difficile contact precautions
C. difficile spreads by contact with spores, so contact precautions with gown and gloves, dedicated equipment and sporicidal environmental cleaning are needed. Alcohol does not kill the spores, so hands are washed with soap and water, which removes them mechanically.
Why the others are wrong
- C – A respirator is for airborne organisms; C. difficile is not transmitted through the air.
- F – Negative-pressure rooms are for airborne infections; a private room with contact precautions is what is needed.

80Question
A client hospitalized with pulmonary tuberculosis has been taking four-drug therapy for 2 weeks and asks when the isolation can end. Which finding indicates that airborne precautions can be discontinued?
- Three consecutive sputum smears negative for acid-fast bacilli, with clinical improvement on therapy
- A repeat tuberculin skin test with no induration
- A normal temperature for 24 hours and a decrease in cough
- A chest x-ray that shows the cavity is smaller than on admission
Show the answer and explanation
Answer: A. Three consecutive sputum smears negative for acid-fast bacilli, with clinical improvement on therapy
Topic: tuberculosis: ending airborne precautions
A hospitalized client with pulmonary tuberculosis is considered no longer infectious when the client is on effective therapy, is improving clinically, and has three consecutive sputum smears negative for acid-fast bacilli collected at separate times. Sputum is the direct measure of whether organisms are still being expelled.
Why the others are wrong
- B – The skin test shows prior exposure to the organism, stays positive, and says nothing about infectiousness.
- C – Symptoms improving is one requirement but does not by itself show that bacilli are no longer in the sputum.
- D – X-ray changes resolve slowly and do not show whether the client is still expelling organisms.

81Question
A charge nurse is making assignments for a child admitted with varicella (chickenpox) whose lesions are still forming. Which staff member is the most appropriate to assign to this client?
- An RN who is 10 weeks pregnant and has no history of varicella or vaccination
- A float RN who is unsure whether chickenpox occurred in childhood
- An RN with documentation of two doses of varicella vaccine
- An LPN/LVN who takes immunosuppressants after a kidney transplant and has no record of immunity
Show the answer and explanation
Answer: C. An RN with documentation of two doses of varicella vaccine
Topic: varicella staff assignment
Varicella is highly contagious by the airborne and contact routes until all lesions are crusted. Only staff with evidence of immunity, such as documented vaccination, should care for the client; susceptible staff should not enter the room when immune caregivers are available.
Why the others are wrong
- A – A susceptible pregnant nurse risks severe maternal illness and fetal harm from varicella.
- B – Without evidence of immunity this nurse must be treated as susceptible.
- D – An immunosuppressed, non-immune caregiver is at risk of severe disseminated varicella.

82Question
A client receiving chemotherapy has an absolute neutrophil count of 400/mm3. Which interventions does the nurse include in the plan of care?
Select all that apply.
- Place the client in a private room
- Take the temperature rectally every 4 hours for accuracy
- Ask visitors with a cough or fever not to visit
- Move the fresh flowers and potted plant to the windowsill
- Place the client in a negative-pressure room
- Perform hand hygiene before every contact with the client
Show the answers and explanation
Answers: A, C and F.
- A – Place the client in a private room
- C – Ask visitors with a cough or fever not to visit
- F – Perform hand hygiene before every contact with the client
Topic: neutropenic precautions
A severely neutropenic client cannot mount a normal defence, so care aims to keep organisms away: a private room, strict hand hygiene by everyone who enters, and screening of visitors. Standing water and soil carry bacteria and fungi, and procedures that break the mucosa are avoided.
Why the others are wrong
- B – Rectal temperatures, suppositories and enemas can injure the mucosa and introduce bacteria into the blood.
- D – Fresh flowers and plants harbour bacteria and fungi and are removed from the room, not just moved within it.
- E – Negative pressure pulls corridor air into the room; it is used to contain airborne infection, not to protect this client.

83Question
A client arrives at the emergency department triage desk with a fever, severe headache, a stiff neck and a petechial rash on the trunk. The waiting room is crowded. Which action does the triage nurse take first?
- Draw blood for cultures and a complete blood count
- Place a surgical mask on the client and move the client to a private room
- Complete a full neurological assessment at the triage desk
- Collect the names of the people sitting near the client in the waiting room
Show the answer and explanation
Answer: B. Place a surgical mask on the client and move the client to a private room
Topic: droplet precautions at triage
The findings suggest meningococcal disease, which spreads by respiratory droplets. Masking the client and moving the client out of the crowded area immediately starts droplet precautions and protects others; it takes seconds and care then continues in the room.
Why the others are wrong
- A – Laboratory work is needed promptly but is done in the private room once others are protected.
- C – A full assessment at the triage desk prolongs exposure of the people nearby; it is done after the client is isolated.
- D – Identifying contacts for possible prophylaxis follows later and does not stop ongoing exposure.

84Question
A nurse has performed hand hygiene and is about to enter the room of a client on contact and droplet precautions to suction a tracheostomy. In which order does the nurse put on the protective equipment?
- Gown, mask, eye protection, gloves
- Gloves, gown, mask, eye protection
- Mask, eye protection, gloves, gown
- Gown, gloves, eye protection, mask
Show the answer and explanation
Answer: A. Gown, mask, eye protection, gloves
Topic: donning order
The recommended sequence is gown first, then mask or respirator, then goggles or face shield, and gloves last so that the glove cuffs can be pulled over the gown cuffs. Putting gloves on last also keeps them clean for touching the client.
Why the others are wrong
- B – Gloves put on first are contaminated by handling the other items and cannot be pulled over the gown cuffs.
- C – Gloves put on before the gown leave the wrists exposed because the glove cuff cannot cover the gown cuff.
- D – Adjusting the mask and eye protection on the face with gloved hands contaminates the gloves and the face.

85Question
A nurse has helped a client with confirmed Clostridioides difficile infection after an episode of stool incontinence. The nurse removes the gown and gloves before leaving the room. Which method of hand hygiene should the nurse use?
- Rub the hands with an alcohol-based product until dry
- Wash the hands with soap and water
- Rub the hands with an alcohol-based product and then put on clean gloves
- Rinse the hands under running water and then use an alcohol-based product
Show the answer and explanation
Answer: B. Wash the hands with soap and water
Topic: hand hygiene method
Alcohol does not kill the spores of Clostridioides difficile, so the hands are washed with soap and water, which removes spores by friction and rinsing. Soap and water is also required whenever the hands may be soiled with body substances, as after contact with stool.
Why the others are wrong
- A – Alcohol-based products do not destroy spores and are not adequate after contact with stool.
- C – Gloves after the alcohol rub do nothing about spores left on the hands.
- D – Rinsing without soap does not remove spores effectively, and alcohol afterwards adds nothing against them.

86Question
A nurse is teaching a new staff member when an alcohol-based hand rub is the appropriate method of hand hygiene. Which situations should the nurse include?
Select all that apply.
- Before measuring a client's blood pressure
- After removing gloves used to empty a wound drain, with no visible soiling of the hands
- When the hands are visibly soiled with blood
- After using the restroom
- When moving from care of a client's wound to care of the same client's IV site
Show the answers and explanation
Answers: A, B and E.
- A – Before measuring a client's blood pressure
- B – After removing gloves used to empty a wound drain, with no visible soiling of the hands
- E – When moving from care of a client's wound to care of the same client's IV site
Topic: hand hygiene indications
An alcohol-based rub is the preferred method in most clinical situations: before and after touching a client, after removing gloves, and when moving from a contaminated body site to a clean one, provided the hands are not visibly soiled. Soap and water is used when the hands are visibly soiled, after using the restroom and before eating.
Why the others are wrong
- C – Visible soiling with blood requires soap and water because alcohol does not remove organic material.
- D – After using the restroom the hands are washed with soap and water.

87Question
A nurse is planning routine morning assessments for four stable clients. Which client should the nurse see first?
- A client with diarrhea caused by Clostridioides difficile
- A client with a draining leg wound that grew methicillin-resistant Staphylococcus aureus (MRSA)
- A client receiving chemotherapy whose absolute neutrophil count is very low
- A client 1 day after surgery who has a clean, dry abdominal incision
Show the answer and explanation
Answer: C. A client receiving chemotherapy whose absolute neutrophil count is very low
Topic: order of care to limit transmission
When all clients are stable, the order of care is used to limit transmission: the client most vulnerable to infection is seen first, and clients with known transmissible infections last. A neutropenic client has almost no defense against organisms carried from other rooms.
Why the others are wrong
- A – A client with C. difficile is a source of spores and is seen toward the end of rounds.
- B – A draining wound with a resistant organism is a source of transmission; this client is seen after the uninfected clients.
- D – This client is uninfected and is seen early, but is far less vulnerable than a client with almost no neutrophils.

88Question
A nursing home resident who has an indwelling urinary catheter is colonized with a multidrug-resistant organism. The resident has no diarrhea and no uncontained drainage and is placed on enhanced barrier precautions. Which statement by unlicensed assistive personnel (UAP) shows correct understanding?
- 'I will wear a gown and gloves when I bathe, dress or transfer the resident or handle the catheter, and the resident can still go to the dining room.'
- 'I will wear a gown and gloves every time I enter the room, and the resident must stay in the room.'
- 'I only need gloves when I empty the catheter bag, the same as for any other resident.'
- 'I will wear a mask and eye protection every time I enter the room.'
Show the answer and explanation
Answer: A. 'I will wear a gown and gloves when I bathe, dress or transfer the resident or handle the catheter, and the resident can still go to the dining room.'
Topic: enhanced barrier precautions
Enhanced barrier precautions are used in nursing homes for residents with wounds or indwelling devices or who are colonized or infected with a multidrug-resistant organism. Gown and gloves are worn during high-contact care activities such as bathing, dressing, transferring, toileting and device or wound care, and the resident is not restricted to the room.
Why the others are wrong
- B – Gown and gloves on every entry with room restriction describes contact precautions, used for example with uncontained drainage or diarrhea.
- C – Standard precautions alone are not enough; a gown and gloves are added for high-contact care.
- D – A mask and eye protection are for splashes or respiratory spread and are not what enhanced barrier precautions add.

89Question
A nurse is caring for a client who has an indwelling urinary catheter. Which actions help prevent a catheter-associated urinary tract infection?
Select all that apply.
- Irrigating the catheter with an antiseptic solution every shift
- Keeping the drainage bag below the level of the bladder and off the floor
- Reviewing each day whether the catheter is still needed and asking for its removal when it is not
- Disconnecting the catheter from the tubing to collect a urine specimen
- Resting the drainage bag on the client's abdomen during transport
- Securing the catheter to prevent movement and pulling
Show the answers and explanation
Answers: B, C and F.
- B – Keeping the drainage bag below the level of the bladder and off the floor
- C – Reviewing each day whether the catheter is still needed and asking for its removal when it is not
- F – Securing the catheter to prevent movement and pulling
Topic: CAUTI prevention
Prevention rests on limiting the time the catheter is in place, keeping the drainage system closed, maintaining unobstructed downward flow, and preventing urethral trauma. Each day the catheter remains increases the risk, so prompt removal is the single most effective measure.
Why the others are wrong
- A – Routine irrigation opens the closed system and is not recommended for preventing infection.
- D – Specimens are taken from the sampling port after cleansing it; disconnecting the tubing breaks the closed system.
- E – A bag placed above the bladder allows urine to flow back into the bladder.

90Question
A nurse is caring for a client who is receiving mechanical ventilation through an endotracheal tube. Which measures help prevent ventilator-associated pneumonia?
Select all that apply.
- Instilling normal saline into the endotracheal tube before each suctioning
- Keeping the head of the bed elevated 30 to 45 degrees unless contraindicated
- Changing the ventilator circuit every day
- Interrupting sedation daily as prescribed and assessing readiness to be weaned
- Providing regular oral care that includes toothbrushing
Show the answers and explanation
Answers: B, D and E.
- B – Keeping the head of the bed elevated 30 to 45 degrees unless contraindicated
- D – Interrupting sedation daily as prescribed and assessing readiness to be weaned
- E – Providing regular oral care that includes toothbrushing
Topic: VAP prevention
Ventilator-associated pneumonia arises mainly from aspiration of secretions from the mouth and stomach and from prolonged intubation. Elevating the head of the bed reduces aspiration, oral care reduces the bacterial load in the mouth, and daily sedation interruption with assessment of readiness to wean shortens the time on the ventilator.
Why the others are wrong
- A – Routine saline instillation is not recommended; it can carry organisms into the lower airway and reduce oxygenation.
- C – Circuits are changed only when visibly soiled or malfunctioning; routine changes increase handling without reducing infection.

91Question
A nurse has set up a sterile field on an overbed table, using a cloth drape, in preparation for inserting an indwelling urinary catheter. While pouring, the nurse splashes sterile saline onto the drape, and the wet area soaks through to the table. Which action should the nurse take?
- Cover the wet area with a sterile towel and continue
- Discard the field and set up a new one with new supplies
- Continue, because the solution that was spilled is sterile
- Move the supplies away from the wet area and continue
Show the answer and explanation
Answer: B. Discard the field and set up a new one with new supplies
Topic: break in surgical asepsis
Moisture that passes through a sterile barrier to an unsterile surface draws microorganisms up into the field by capillary action, so the whole field is considered contaminated. A contaminated field cannot be made sterile again; it is replaced.
Why the others are wrong
- A – A sterile towel placed on a contaminated drape becomes contaminated in turn.
- C – The sterility of the saline is irrelevant; the moisture links the field to the unsterile table.
- D – The field as a whole is considered contaminated, not just the wet patch.

92Question
A nurse is to obtain a swab for culture from a client's open abdominal wound before the first dose of an antibiotic. Which technique should the nurse use?
- Collect the swab from the drainage that has pooled in the old dressing and the wound
- Rub the swab along the skin at the edges of the wound
- Cleanse the wound with sterile normal saline, then rotate the swab over clean, healthy-looking tissue in the wound bed
- Cleanse the wound with an antiseptic solution, then swab the center of the wound
Show the answer and explanation
Answer: C. Cleanse the wound with sterile normal saline, then rotate the swab over clean, healthy-looking tissue in the wound bed
Topic: wound culture technique
A wound culture should show the organisms infecting the tissue, not those living in old exudate or on the surrounding skin. The wound is first cleansed with sterile saline to remove surface drainage, and the swab is then taken from viable tissue in the wound bed.
Why the others are wrong
- A – Pooled drainage contains colonizing organisms that may not be the cause of the infection.
- B – Wound edges are contaminated with normal skin flora.
- D – An antiseptic can kill organisms at the surface and produce a false-negative culture.

93Question
A nurse who is scheduled to work on an oncology unit wakes with vomiting and watery diarrhea. Which action should the nurse take?
- Go to work and wear a mask and gloves for all client care
- Go to work and ask to be assigned only to clients who are not neutropenic
- Take an antidiarrheal medication, go to work and perform strict hand hygiene
- Notify the supervisor and stay away from work until the period after symptoms end that the employer's policy requires
Show the answer and explanation
Answer: D. Notify the supervisor and stay away from work until the period after symptoms end that the employer's policy requires
Topic: health care worker illness and work restriction
Health care personnel with acute vomiting or diarrhea are excluded from work until symptoms have resolved for the period set by occupational health policy, because gastrointestinal infections spread easily through contact with clients, surfaces and food. The duty to protect clients, especially those who are immunocompromised, outweighs staffing convenience.
Why the others are wrong
- A – A mask and gloves do not prevent contamination of surfaces and equipment by an enteric organism.
- B – All clients, staff and shared surfaces on the unit would still be exposed.
- C – An antidiarrheal reduces symptoms but not shedding of the organism.

94Question
Over 24 hours, five clients and two staff members on a medical unit develop sudden vomiting and watery diarrhea, and norovirus is suspected. Which measures should the charge nurse put in place?
Select all that apply.
- Place symptomatic clients on contact precautions and group them together where single rooms are not available
- Have staff wash their hands with soap and water after caring for affected clients
- Move the symptomatic clients to negative-pressure rooms
- Keep ill staff away from work until 48 hours after their symptoms have stopped
- Ask the provider for preventive antibiotics for clients who share rooms with affected clients
Show the answers and explanation
Answers: A, B and D.
- A – Place symptomatic clients on contact precautions and group them together where single rooms are not available
- B – Have staff wash their hands with soap and water after caring for affected clients
- D – Keep ill staff away from work until 48 hours after their symptoms have stopped
Topic: norovirus outbreak
Norovirus spreads by the fecal-oral route, through contaminated hands and surfaces, and very few viral particles are needed. Control rests on contact precautions with cohorting, handwashing with soap and water during an outbreak, and excluding ill staff until at least 48 hours after symptoms end, because shedding continues after recovery.
Why the others are wrong
- C – Negative-pressure rooms are for airborne infections; norovirus calls for contact precautions.
- E – Antibiotics have no effect on a virus and expose clients to side effects, including C. difficile infection.

95Question
A resident of a long-term care facility is diagnosed with typical (non-crusted) scabies and receives the first application of a prescribed scabicide this morning. Which action should the nurse plan?
- Wear a gown and gloves for direct contact with the resident and the bedding until 24 hours after the treatment
- Wear a fitted N95 respirator when entering the resident's room
- Discard the resident's clothing and bedding as regulated medical waste
- Use standard precautions only, because the mite does not survive away from the skin
Show the answer and explanation
Answer: A. Wear a gown and gloves for direct contact with the resident and the bedding until 24 hours after the treatment
Topic: scabies precautions
Scabies spreads by direct skin-to-skin contact and, less often, through clothing and bedding. Contact precautions are kept until 24 hours after effective treatment has been started. Clothing and bedding are bagged and laundered in hot water and dried on a hot cycle, not thrown away.
Why the others are wrong
- B – Scabies is not spread through the air; a respirator gives no protection against it.
- C – Hot washing and drying kills mites; discarding belongings is unnecessary.
- D – Mites live for a time on clothing and linen, and skin contact during care transmits them, so contact precautions are required.

96Question
A visitor sitting in a crowded emergency department waiting room is coughing frequently without covering the mouth. The visitor says, 'It is just a cold.' Which action should the triage nurse take first?
- Ask the visitor to wait outside the building until the family member is discharged
- Fit the visitor with an N95 respirator and call infection control
- Offer a mask and tissues, show where the hand sanitizer is, and ask the visitor to sit apart from others
- Place the visitor in a negative-pressure room until the cause of the cough is known
Show the answer and explanation
Answer: C. Offer a mask and tissues, show where the hand sanitizer is, and ask the visitor to sit apart from others
Topic: respiratory hygiene for visitors
Respiratory hygiene and cough etiquette apply to every person with respiratory symptoms who enters a health care setting, including visitors: a mask, tissues, hand hygiene and distance from others. These measures contain droplets at the source without needing a diagnosis.
Why the others are wrong
- A – Exclusion from the building is not required for a cough; source control measures are the standard.
- B – An N95 is fit-tested respiratory protection for staff; a coughing person is given an ordinary mask for source control.
- D – Airborne isolation is for suspected airborne infection; a cough alone does not justify it.

97Question
The nurse educator observes staff preparing injections on a busy clinic day. Which practices are correct?
Select all that apply.
- Changing the needle but keeping the same syringe to draw a second dose from a multi-dose vial for the same client
- Using a new needle and a new syringe every time a vial is entered
- Drawing saline flushes for several clients from one bag of IV solution
- Discarding what remains in a single-dose vial after one use, even when a large amount is left
- Keeping an opened multi-dose vial on the counter in the treatment room where clients receive their injections
- Scrubbing the vial's rubber stopper with alcohol and letting it dry before each entry
Show the answers and explanation
Answers: B, D and F.
- B – Using a new needle and a new syringe every time a vial is entered
- D – Discarding what remains in a single-dose vial after one use, even when a large amount is left
- F – Scrubbing the vial's rubber stopper with alcohol and letting it dry before each entry
Topic: safe injection practices
Safe injection practice rests on one needle, one syringe, one time; single-dose containers for a single client and a single use; and disinfection of the stopper before each entry. A used syringe carries contamination back into the vial even when the needle is changed, and a common bag or a vial kept at the point of care becomes a shared source of infection.
Why the others are wrong
- A – The syringe barrel and plunger are contaminated after use; a fresh needle does not prevent the vial being contaminated.
- C – A bag of IV solution is a single-client item; using it as a shared source of flushes has caused outbreaks.
- E – Multi-dose vials are kept away from the immediate client treatment area; one that enters it is used for that client only.
