A nurse is preparing to administer magnesium sulfate 1 g/hr via continuous IV infusion to a client. Available is magnesium sulfate 40 g in 0.9% sodium chloride 000 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["25"]
To calculate the IV pump setting, you need to determine how many milliliters per hour will provide 1 gram of magnesium sulfate. With 40 grams of magnesium sulfate in 1000 mL, you have a concentration of 0.04 grams per mL. To administer 1 gram per hour, divide the desired dose (1 gram) by the concentration (0.04 grams/mL), which equals 25 mL. Therefore, the nurse should set the IV pump to deliver 25 mL per hour.

Correct Answer is ["0.12"]
Explanation
To determine the correct dosage of ferrous sulfate drops for the newborn, one must use the formula: (Desired Dose / Concentration) = Volume to Administer. In this case, the desired dose is 15 mg, and the concentration available is 75 mg per 0.6 mL. Therefore, the calculation would be (15 mg / 75 mg) * 0.6 mL, which equals 0.12 mL.
Correct Answer is B
Explanation
A. Offering the medication preemptively is not indicated because the prescription specifies administration only if saturation occurs within 15 minutes.
B. Administering the medication once if the client saturates the perineal pad within 15 minutes aligns with the prescription's directive to use oxytocin to manage excessive bleeding promptly.
C. Waiting 15 minutes after saturation does not align with the urgency indicated by the prescription, which specifies immediate administration upon saturation.
D. Administering the medication each time the pad saturates within 15 minutes could lead to excessive dosing and is not in accordance with the prescription's one-time use instruction.
