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 ["3.5"]
Explanation
To convert the weight of the newborn from grams to kilograms, one needs to divide the number of grams by 1,000 since there are 1,000 grams in a kilogram. Therefore, a newborn who weighs 3,500 grams would be recorded as weighing 3.5 kilograms.
Correct Answer is ["105"]
Explanation
To calculate the IV pump setting, we need to convert the dosage from mg/min to mg/hr, and then find out how many mL/hr this corresponds to, given the concentration of the solution. First, multiply the ordered dose by 60 minutes to convert to an hourly rate: 7 mg/min * 60 min/hr = 420 mg/hr. Next, since we have 1 g of lidocaine in 250 mL, we convert 1 g to mg, which is 1000 mg. Now, we have 1000 mg in 250 mL, so we need to find out how many mL are needed for 420 mg. Using a proportion, we have 1000 mg/250 mL = 420 mg/x mL. Solving for x gives us x = (420 mg * 250 mL) / 1000 mg, which equals 105 mL. Therefore, the nurse should set the IV pump to deliver 105 mL/hr.
