Answer and Explanation

The Correct Answer is B

Step 3: Calculate dose per administration (every 6 hr).

6000 mg ÷ 4 = 1500 mg

Step 4: Calculate number of tablets per dose.

1500 mg ÷ 500 mg/tab = 3 tablets

Answer:

3 tablets per dose.

Correct Answer is D

Explanation

Confusion is the priority for the nurse to report to the provider because it can be a sign of a serious side effect of citalopram.

Choice A is wrong because weight loss is not mentioned as a serious side effect of citalopram.
Choice B is wrong because bruxism is not mentioned as a serious side effect of citalopram.
Choice C is wrong because insomnia is a common side effect of citalopram but not considered a serious side effect that requires immediate medical attention.

A. The client had chemotherapy 12 hr before the medication was administered. B. The medication vial sat at room temperature for 2 hr before it was administered. C. The client's absolute neutrophil count was 2,500/mm³ before the medication was administered. D. The nurse flushed the client's IV line with dextrose 5% in water before and after the medication was administered.

Correct Answer is A

Explanation

Choice A rationale: Administering filgrastim after chemotherapy is a standard practice to boost white blood cell count. However, filgrastim should not be given within 24 hours before or after chemotherapy, as it can affect the efficacy and increase the risk of side effects. Administering the medication 12 hours after chemotherapy falls within this contraindicated window, necessitating an incident report.

Choice B rationale: Filgrastim can be stored at room temperature for short periods, and 2 hours is generally within acceptable limits for stability.

Choice C rationale: An absolute neutrophil count of 2,500/mm³ is within the normal range, and there is no contraindication for administering filgrastim.

Choice D rationale: Flushing the client's IV line with dextrose 5% in water before and after administering filgrastim is not appropriate, as this medication is typically administered with saline solution. Using an incorrect flushing solution could affect the medication's efficacy or compatibility, necessitating an incident report.
