Answer and Explanation

The Correct Answer is B

1500 mg ÷ 500 mg/tab = 3 tablets

Answer:

3 tablets per dose.

Correct Answer is ["B","C","D"]

Explanation

These are all risk factors for an adverse drug reaction in older adults.

Decreased renal function is a disease-related factor that can increase the risk of adverse drug reactions.

Multiple health problems or complex comorbidity can also increase the risk of adverse drug reactions.

Polypharmacy is a medication-related factor that can increase the risk of adverse drug reactions.

Choice A is wrong because Decreased percentage of body fat, is not an answer because it is not mentioned as a risk factor for adverse drug reactions in older adults in the search results.

Choice E, Increased rate of absorption, is not an answer because it is not mentioned as a risk factor for adverse drug reactions in older adults in the search results.

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.
