NR-224 Fundamentals – Skills - Set 2 - Part 3

Correct Answer: Discard the field and set up again

Moisture wicks organisms from the non-sterile table through the drape to the sterile surface, which is strike-through contamination. A wet field is a contaminated field, so the entire setup is discarded and replaced with fresh sterile supplies. Option b is incorrect because blotting cannot undo wicking that has already happened. Organisms travel through the wet fabric within seconds, and pressing gauze onto that area only contaminates the gauze as well. Option c is incorrect because covering a break in sterility hides it rather than correcting it. The towel would rest on a surface that is already contaminated, and moisture would continue to wick upward into it. Option d is incorrect because there is no partial sterility to preserve. Shifting instruments to a dry corner treats the drape as though contamination stayed where it landed, and the whole field has already failed.

Correct Answer: The convalescent stage of the process

Convalescence runs from the disappearance of acute signs and symptoms to the return of the client's usual health. Energy returns last, so lingering fatigue is the expected finding in this stage. Option a is incorrect because the illness stage is defined by disease-specific findings actively present, such as the productive cough, fever and consolidation of pneumonia. Those findings have already resolved in this client. Option c is incorrect because prodromal describes the earliest vague complaints that precede a diagnosis. Fatigue after a resolved pneumonia looks similar on paper, yet it follows the illness rather than announcing one. Option d is incorrect because incubation is the silent interval between exposure and the first symptom, when the client feels entirely well. This client has already been through the full course of an infection.

Correct Answer: Impaired tissue integrity with wound infection

The purulent drainage and fever show that infection has already occurred, so the diagnosis must name the actual problem. Impaired tissue integrity with infection describes the damaged tissue this client has now, and it directs treatment. Option a is incorrect because a risk diagnosis carries no signs and symptoms, since the problem has not yet developed. Purulent drainage and fever are defining characteristics, and their presence converts the risk into an actual problem. Option b is incorrect because nothing in this scenario suggests the client misunderstands wound care or lacks information. Knowledge deficit may be identified later during teaching, but the priority problem here is the infected tissue itself. Option d is incorrect because this diagnosis addresses the psychological burden that isolation places on a client, an issue that may arise if precautions are ordered. It names a response to treatment rather than the infection.

Correct Answer: Cleanse with normal saline and swab viable tissue

Old surface exudate and slough grow colonizing organisms rather than the ones invading the tissue. Cleansing with normal saline first and swabbing the base of viable tissue gives the laboratory the organism actually causing the infection. Option b is incorrect because sampling before cleansing captures whatever has settled on the surface, including skin flora and dead material. The result names organisms that are simply sitting there and may send therapy in the wrong direction. Option c is incorrect because a removed dressing has been in contact with the environment and the client's skin for hours. Anything cultured from it reflects contamination and the age of the drainage, not the wound bed at this moment. Option d is incorrect because intact skin carries normal resident flora that never invaded the tissue below. Culturing it yields a predictable list of surface organisms while the true pathogen in the wound goes unidentified.

Correct Answer: Notify the provider of febrile neutropenia

Fever in a neutropenic client is an oncologic emergency. Without neutrophils the client cannot form pus or mount local redness, so fever may be the only sign, and treatment cannot wait. Option a is incorrect because cooling treats a number on a thermometer while the underlying infection continues unchecked. Aggressive external cooling can also trigger shivering, which raises oxygen demand in an already fragile client. Option b is incorrect because waiting an hour delays cultures and antibiotics that guidelines want started within that same hour. A neutropenic client can move from fever to septic shock inside that window. Option c is incorrect because supportive measures and charting are appropriate only after the emergency has been reported. The absent wound findings tempt students to downgrade the urgency, and that is exactly the trap.

Correct Answer: Switch to a bleach based sporicidal product

Spores survive quaternary ammonium and alcohol alike, so the room needs an agent registered as sporicidal, typically bleach based, left wet for the labeled contact time. Terminal cleaning after discharge uses that product on every surface. Option a is incorrect because terminal cleaning after a discharge covers every surface, the equipment and the privacy curtain, not the short list handled during a daily wipe down. Narrowing the scope leaves spores behind on furniture. Option c is incorrect because ventilation dilutes airborne particles, which is a concern for tuberculosis or measles rooms rather than this one. Spores sit on solid surfaces and are removed by friction and a sporicidal chemical. Option d is incorrect because alcohol has no activity against the spore form at all, so a second pass with it repeats a failure. The same fact drives soap and water hand hygiene for these clients.

Correct Answer: Use another container and request a replacement

A sharps container is replaced when it reaches the fill line, and no one reaches into it or forces items down. The nurse disposes of the syringe in another container and asks for the full one to be exchanged. Option b is incorrect because pushing on the contents drives the hand toward exposed needle points. An overfilled container also jams at the opening, and both conditions produce the injuries the container exists to prevent. Option c is incorrect because the scoop technique is a last resort for the rare situation in which recapping cannot be avoided. A full container is not that situation, and the safety device is already engaged. Option d is incorrect because the person who used a sharp disposes of it immediately. Setting the syringe down transfers the hazard to whoever finds it next, including housekeeping staff and the client's visitors.

Correct Answer: Draw both sets of blood cultures first

Even one dose of antibiotic can suppress bacterial growth enough to produce a false negative culture, leaving the team without the organism and its sensitivities. Cultures are drawn first, then the antibiotic is given promptly. Option a is incorrect because giving the drug ahead of the specimens sacrifices the one chance to identify the organism. The antibiotic still needs to be given quickly, but it follows the cultures rather than preceding them. Option b is incorrect because dose verification is a routine safety check that belongs with medication preparation and does not address the timing problem in this order. Nothing about a pharmacy call preserves the culture result. Option c is incorrect because an antipyretic treats the discomfort of fever without touching the source of the infection, and comfort measures never outrank obtaining the diagnostic specimen. Fever control can wait until the cultures are drawn.

Correct Answer: The mucous membrane clearance mechanisms

Smoking and anesthesia paralyze cilia, opioids and immobility suppress the cough and pool secretions, and acid suppression raises gastric pH so swallowed organisms survive. Every one of those hits mechanical clearance. Option a is incorrect because the surgical incision does breach the skin, yet that is a single defect at one site. Nothing in the medication list or the smoking history affects the skin barrier itself. Option b is incorrect because antibody production falls with chemotherapy, corticosteroids, HIV, splenectomy or protein malnutrition. Opioids, acid suppression and tobacco do not damage B lymphocytes or the memory they create. Option d is incorrect because broad-spectrum antibiotics are what strip resident flora and open the door to Clostridioides difficile or thrush. No antibiotic appears anywhere in this client's history.

Correct Answer: Redirect the student to soap and water

Clostridioides difficile forms spores that alcohol cannot kill. Only the friction, lather and rinsing of handwashing physically remove spores from the skin, so soap and water is mandatory after caring for this client. Option a is incorrect because the student has applied a correct general rule to the one exception. Alcohol rub is preferred for most clinical moments, yet spores survive it, leaving the hands still contaminated. Option c is incorrect because an antiseptic wipe is a waterless product that solves the problem of no available sink. It still lacks the running water and rinsing that carry spores off the skin. Option d is incorrect because repeating an ineffective product does not make it effective. Two applications of alcohol leave the same spore burden on the hands, and the extra drying damages skin that is already irritated.
