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. Muscle rigidity of the extremities: This finding is more indicative of hyperkalemia or severe electrolyte imbalances but is not a common symptom of hypokalemia.
B. Bounding radial pulses: This finding is more associated with hypervolemia or hyperkalemia, not with hypokalemia caused by furosemide.
C. Depressed deep tendon reflexes: This is the correct response, as low potassium levels (hypokalemia) can lead to diminished reflexes due to its role in neuromuscular function.
D. Increased bowel motility: This is incorrect, as hypokalemia typically results in decreased bowel motility and may cause constipation rather than increased motility.
Correct Answer is D
Explanation
Rationale:
A. Mostly cloudy: This option appears to be incorrectly stated. It does not pertain to a critical client assessment related to morphine administration.
B. Apical heart rate: Monitoring the heart rate is important, but respiratory depression is a more immediate and life-threatening concern with morphine administration, so it is not the first priority.
C. Blood pressure: Morphine can cause hypotension, but this is not as critical as respiratory depression, which must be assessed first in opioid administration.
D. Respiratory rate: The most critical assessment when administering morphine is the respiratory rate, as opioid medications like morphine can cause respiratory depression, which can be life-threatening if not addressed.
E. Level of consciousness: While important, changes in consciousness typically follow respiratory depression, so assessing the respiratory rate takes priority.
