A nurse is caring for a client who has a new prescription for alosetron. Which of the following therapeutic effects should the nurse expect the client to experience?

A decrease in the amount of gastric acid production

A decrease in the frequency of defecation

An increase in gastric motility

An increase in the absorption of water into the intestine

Answer and Explanation

The Correct Answer is B

A. A decrease in the amount of gastric acid production: Alosetron is not used to decrease gastric acid production. This effect is more associated with medications such as proton pump inhibitors or H2 blockers.

B. A decrease in the frequency of defecation: Alosetron is used to treat irritable bowel syndrome with diarrhea (IBS-D) by reducing bowel movement frequency and improving stool consistency.

C. An increase in gastric motility: Alosetron works by decreasing intestinal motility, which helps reduce diarrhea, not by increasing it.

D. An increase in the absorption of water into the intestine: Alosetron does not specifically increase water absorption into the intestine. Its primary effect is slowing intestinal transit to reduce diarrhea.

Correct Answer is C

Explanation

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 ["100"]

Explanation

Infusion rate (mL/hr) = Volume to be infused (mL) / Time (hr)

In this case:

Volume to be infused = 100 mL
Time = 1 hour

Plugging the values into the formula:

Infusion rate = 100 mL / 1 hour = 100 mL/hr
