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. 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.

A. Magnesium 2.5 mEq/L (1.3 to 2.1 mEq/L) B. Potassium 5.4 mEq/L (3.5 to 5 mEq/L) C. WBC 2,500/mm³ (5,000 to 10,000/mm³) D. Sodium 134 mEq/L (136 to 145 mEq/L)

Correct Answer is C

Explanation

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.
