Correct Answer is B

Explanation

Choice A rationale
This is incorrect because the prescription is for one time only, not for repeated doses. Waiting 15 minutes to administer the medication after the client saturates a perineal pad could delay necessary treatment.
Choice B rationale
This is correct because the prescription states to administer the medication “one time only” if the client saturates the perineal pad within 15 minutes. The nurse should give the medication once when the pad becomes saturated within the specified time frame.
Choice C rationale
This is incorrect because the prescription is not for preventive administration. Offering the medication now to prevent saturation of the perineal pad does not align with the prescription instructions.
Choice D rationale
This is incorrect because the prescription is for one time only, not for repeated doses. Administering the medication every 15 minutes regardless of pad saturation could lead to overmedication and potential side effects.

A. “I like to have a cup of hot tea in the afternoon, so I will take my medication then.”. B. “I will wait 2 hours after eating my evening meal to take my medication.”. C. “I will take my medication when I begin eating my evening meal.”. D. “If I don’t eat an evening meal, I will wait to take my medication at bedtime.”.

Correct Answer is C

Explanation

Choice A rationale
Metformin should be taken with meals to help reduce stomach or bowel side effects that may occur during the first few weeks of treatment. Taking it in the afternoon with tea would not align with the prescribed timing.
Choice B rationale
Waiting 2 hours after eating the evening meal to take metformin is not recommended. Metformin should be taken with meals to help reduce gastrointestinal side effects.
Choice C rationale
Taking metformin when beginning the evening meal is correct as it helps reduce gastrointestinal side effects and ensures proper absorption.
Choice D rationale
If the client does not eat an evening meal, they should not wait until bedtime to take metformin. It should be taken with food to minimize gastrointestinal side effects.
