Correct Answer is B
Explanation
Choice A reason: Giving the medication each time the client saturates the perineal pad within 15 minutes is incorrect. The prescription specifies a one-time administration of oxytocin, not repeated doses. Administering the medication multiple times could lead to an overdose and potential complications, as oxytocin is a powerful drug used to control postpartum bleeding by stimulating uterine contractions.
Choice B reason: This is the correct interpretation of the prescription. The nurse should administer the medication once if the client saturates the perineal pad within 15 minutes. This means that if the client experiences heavy bleeding that results in the saturation of a perineal pad within this timeframe, the nurse should give the prescribed dose of oxytocin intramuscularly to help control the bleeding and promote uterine contractions.
Choice C reason: Waiting 15 minutes to administer the medication after the client saturates a perineal pad is incorrect. The prescription does not indicate a delay in administration. Prompt administration of oxytocin is crucial in managing postpartum hemorrhage, as delaying treatment could result in continued heavy bleeding and increased risk of complications for the client.
Choice D reason: Offering the medication now to prevent saturation of the perineal pad is also incorrect. The prescription specifies that the medication should be given in response to the saturation of the perineal pad within 15 minutes, not as a preventive measure. Administering oxytocin without the indicated condition could lead to unnecessary medication use and potential side effects.
Correct Answer is ["10"]
Explanation
The question is asking for the amount of docusate sodium liquid the nurse should administer per dose. The prescription is for 200 mg/day in two equally divided doses, and the liquid form of the medication is 50 mg/5 mL.
Step 1 is to determine the amount of medication needed per dose. Since the total daily dose is 200 mg and it’s divided into two doses, each dose will be 200 mg ÷ 2 = 100 mg.
Step 2 is to convert this dose from mg to mL using the concentration of the liquid medication. The concentration is 50 mg/5 mL, which means that 1 mL contains 50 mg ÷ 5 = 10 mg of the medication.
Step 3 is to calculate the volume of the medication needed for a 100 mg dose. Since 1 mL contains 10 mg, we need 100 mg ÷ 10 mg/mL = 10 mL.
So, the nurse should administer 10 mL of docusate sodium liquid per dose.
