A nurse is caring for a client who has a prescription for vancomycin 1 g IV intermittent infusion over 30 min every 12 hr. Which of the following actions should the nurse take?

Request a serum trough level blood draw for 60 min after completion of infusion.

Change the infusion site after each dose administration.

Contact the provider for prescription clarification.

Request a serum peak level to be drawn 30 min prior to infusion.

Answer and Explanation

The Correct Answer is C

A. Requesting a serum trough level blood draw for 60 min after completion of infusion is incorrect. Trough levels should be drawn just before the next dose (not after infusion completion) to ensure therapeutic drug levels and avoid toxicity.
B. Changing the infusion site after each dose administration is incorrect. Vancomycin can cause phlebitis, but routine site changes after every dose are unnecessary unless signs of irritation or infiltration are present.
C. Contacting the provider for prescription clarification is correct. Vancomycin should be infused over at least 60 minutes to reduce the risk of Red Man Syndrome, a histamine reaction that can cause flushing, hypotension, and rash. A 30-minute infusion is too rapid and should be adjusted.
D. Requesting a serum peak level to be drawn 30 min prior to infusion is incorrect. Peak levels are drawn 30–60 minutes after infusion completion, not before infusion. Trough levels, not peak levels, are used to monitor vancomycin dosing.

Correct Answer is B

Explanation

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.

A. Nitrates B. Sulfa-based medications C. Mostly cloudy D. Antilipemic agents E. Proton pump inhibitors

Correct Answer is B

Explanation

A. Nitrates: Nitrates are primarily used to manage angina or heart conditions and are unrelated to acetazolamide or its potential for allergic reactions.

B. Sulfa-based medications: Acetazolamide is a carbonic anhydrase inhibitor that contains sulfonamide groups. Clients with a sulfa allergy may experience a cross-sensitivity reaction, so it's important to confirm any history of sulfa allergies before administration.

C. Mostly cloudy: This option does not relate to any medication classification and is incorrect.

D. Antilipemic agents: Antilipemics are used to lower cholesterol and are not related to acetazolamide or its potential for allergic reactions.

E. Proton pump inhibitors: Proton pump inhibitors are used to reduce stomach acid and do not have a known cross-sensitivity with acetazolamide.
