Correct Answer is ["26"]

Explanation

Step 1: Calculate the total dose per hour. 1.7 mg/min × 60 min/hr = 102 mg/hr Step 2: Determine the concentration of the solution. 1 g = 1000 mg 1000 mg = 250 mL 102 mg = (102 mg × 250 mL) ÷ 1000 mg = 25.5 mL/hr Step 3: Round to the nearest whole number. 25.5 mL/hr ≈ 26 mL/hr The IV pump should be set to deliver 26 mL/hr.

A. Wait 15 min to administer the medication after the client saturates a perineal pad. B. Administer the medication once if the client saturates the perineal pad within 15 min. C. Offer the medication now to prevent saturation of the perineal pad. D. Administer the medication every 15 min regardless of pad saturation.

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.
