1. What is the drug of choice for herpes simplex virus 1, herpes simplex virus 2, and varicella-zoster virus?

Correct answer: B

Rationale: Acyclovir (Zovirax) is the drug of choice for herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), and varicella-zoster virus (VZV) infections. It works by inhibiting viral DNA replication. Acyclovir is excreted unchanged in the urine, so caution is needed in renal impairment. Choice A, HIV, is incorrect as acyclovir is not the drug of choice for HIV. Choice C, CMV, is incorrect as acyclovir is not the preferred treatment for cytomegalovirus (CMV) infections. Choice D, Influenza A viruses, is incorrect as acyclovir is not used to treat influenza viruses.

2. Which action by a graduate nurse would require the charge nurse to intervene?

Correct answer: A

Rationale: The correct answer is walking in the hallway outside the operating room without a hair covering. In healthcare settings, it is crucial to adhere to infection control measures, which include wearing appropriate attire to prevent the spread of pathogens. Walking in the hallway outside the operating room without a hair covering violates these infection control protocols, necessitating immediate intervention by the charge nurse. Choices B and C are incorrect because putting on surgical attire before entering the operating room and wearing a surgical mask into the holding area are both standard practices that promote patient safety and infection control. Choice D is also incorrect as wearing scrubs from home into the nursing station, while not ideal, is not a violation that warrants immediate intervention compared to breaching infection control protocols near sensitive areas like the operating room.

3. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

Correct answer: B

Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.

4. When teaching bleeding precautions to a client with leukemia, the PN should include which of the following instructions?

Correct answer: A

Rationale: The correct answer is to 'Use a soft toothbrush.' A soft toothbrush is recommended because it is less likely to cause the gums to bleed in clients with leukemia, who are at risk of bleeding due to overcrowding of white cells at the expense of other cell types like platelets. Choice B, 'Use dental floss daily,' is incorrect because dental floss is contraindicated and can make the gums bleed in clients with leukemia. Choice C, 'Hold pressure on any scrapes for 1-2 minutes,' is incorrect because when clotting is impaired, pressure should be held for 5-10 minutes or longer until the bleeding stops. Choice D, 'Use a triple-edged razor,' is incorrect because an electric razor should be used instead of a triple-edged razor to prevent small cuts and bleeding in clients with leukemia.

5. What is the primary sign of displacement following a total hip replacement?

Correct answer: A

Rationale: The correct answer is pain on movement and weight bearing. This pain is the primary sign of prosthesis displacement after a total hip replacement, indicating pressure on nerves or muscles due to dislocation. Hemorrhage is not typically associated with prosthesis displacement. While the affected leg may appear longer, this is not the primary sign of displacement; it might actually be shorter due to muscle spasm. Edema in the incision area is not a primary indicator of prosthesis displacement.
