A nurse is preparing to administer dopamine 5 mcg/kg/min via continuous IV infusion to a newborn who weighs 4.4 kg and has septic shock. Available in dopamine 200 mg in dextrose 5% in water 250 mL. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.7"]
The dose of dopamine in mg/hr: 5 mcg/kg/min x 4.4 kg x 60 min/hr = 1320 mcg/hr Converted to mg: 1320 mcg/hr / 1000 mcg/mg = 1.32 mg/hr
Infusion rate in mL/hr: 1.32 mg/hr / (200 mg/250 mL) = 1.65 mL/hr Rounded off to the nearest tenth: 1.7 mL/hr

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
IV pump rate (mL/hr) = (units/hr x volume) / total units
In this case, the units/hr is 1,000, the volume is 250 mL, and the total units is 25,000. IV pump rate (mL/hr) = (1,000 x 250) / 25,000
Therefore;
IV pump rate (mL/hr) = 250,000 / 25,000 IV pump rate (mL/hr) = 10
Therefore, the nurse should set the IV pump to deliver 10 mL/hr.
