Answer and Explanation

The Correct Answer is ["8"]

Number of tablets = (Dose per administration x Number of administrations per day) / Tablet strength

Number of tablets = (500 mg x 4) / 250 mg

Number of tablets = 2000 mg / 250 mg Number of tablets = 8

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

Correct Answer is B

Explanation

The correct answer is Choice B.

Choice A rationale: This is incorrect because the prescription is for one time only, not for repeated doses.Giving the medication each time the client saturates the perineal pad within 15 min could cause uterine hyperstimulation, water intoxication, or hypotension 1.

Choice B rationale: This is correct because the prescription is for one time only and the indication is saturation of a perineal pad in 15 min or less.This is a sign of postpartum hemorrhage, which is a common and potentially life-threatening complication of childbirth 2.Oxytocin is a uterotonic agent that helps the uterus contract and reduce bleeding 3.

Choice C rationale: This is incorrect because waiting 15 min to administer the medication after the client saturates a perineal pad could result in excessive blood loss and hypovolemic shock. The medication should be given as soon as possible after the indication is met.

Choice D rationale: This is incorrect because offering the medication now to prevent saturation of perineal pad is not the intended use of the prescription. The medication is for treatment, not prevention, of postpartum hemorrhage. Prophylactic oxytocin is usually given intravenously or intramuscularly during or immediately after the delivery of the placenta.
