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 ["0.5"]
Explanation
To administer the correct dose of nalbuphine, which is 10 mg, when you have a concentration of 20 mg/mL, you need to calculate the volume to be administered. The formula to use is: (Dose ordered / Drug concentration) = Volume to administer. Plugging in the values: (10 mg / 20 mg/mL) = 0.5 mL.
Correct Answer is A
Explanation
A. Giving the medication before meals helps to reduce gastric upset, which is a common side effect of nifedipine.
B. Contacting the provider to clarify the prescription is not necessary because the prescription specifies the frequency and route clearly.
C. Discontinuing the medication after three doses without further instruction from the provider could be premature and not in line with the treatment plan for premature contractions.
D. Administering nifedipine sublingually is not the appropriate route for this medication; it is typically administered orally.
