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.

Correct Answer is ["30"]

Explanation

Step 1 is… (0.5 mg/min × 60 min/hr) ÷ 1 mg/mL Step 2 is… 30 mg/hr ÷ 1 mg/mL Step 3 is… 30 mL/hr The final calculated answer is 30 mL/hr.
