A nurse is caring for a client who has varicella-zoster virus. Which of the following medications should the nurse expect to administer?
Mostly cloudy
Acyclovir
Vancomycin
Gentamicin
Quinine
The Correct Answer is B
Rationale:
A. Mostly cloudy: This option does not refer to a medication and is therefore irrelevant in this context.
B. Acyclovir: This is the correct medication for treating varicella-zoster virus, as it is an antiviral drug effective in managing symptoms and reducing the duration of the infection.
C. Vancomycin: This antibiotic is used to treat serious bacterial infections and is not indicated for viral infections like varicella-zoster.
D. Gentamicin: This is an aminoglycoside antibiotic that is ineffective against viral infections and is used primarily for bacterial infections.
E. Quinine: This medication is used to treat malaria and is not relevant for varicella-zoster virus treatment.

Correct Answer is C
Explanation
Rationale:
A. Magnesium 2.5 mEq/L: A magnesium level slightly above the normal range does not indicate an immediate need to discontinue clozapine, as this level is not related to the adverse effects of the drug.
B. Potassium 5.4 mEq/L: While elevated potassium levels can pose a health risk, this is not a direct indicator to discontinue clozapine. Potassium levels can be managed with other interventions.
C. WBC 2,500/mm³: Clozapine carries a risk of agranulocytosis, a condition where the white blood cell (WBC) count becomes dangerously low, leading to severe infection risk. A WBC count of 2,500/mm³ is below the normal range and indicates the need to discontinue clozapine immediately.
D. Sodium 134 mEq/L: A slightly low sodium level is not typically related to clozapine use and does not warrant discontinuation of the medication.
Correct Answer is C
Explanation
Rationale:
A. Applying a warming blanket is not appropriate, as it may exacerbate the client's reaction to the infusion and is not a standard pre-medication strategy.
B. Infusing amphotericin B deoxycholate over 1 hour is too rapid; it is typically infused over 2-6 hours to minimize adverse effects.
C. Administering diphenhydramine prior to the administration of amphotericin B can help prevent or alleviate infusion-related reactions such as fever and chills, which the client experienced during previous infusions.
D. Monitoring vital signs once per hour following administration is insufficient; vital signs should be monitored more frequently during and immediately after the infusion to promptly detect and address any adverse reactions.
