A nurse is preparing to administer propranolol 2 mg by intermittent IV bolus over 15 min. Available is propranolol 2 mg in 50 ml. dextrose 5% in water. 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 ["200"]
To answer this question, we need to calculate the infusion rate of the IV pump. The formula for infusion rate is:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
We are given the volume of the solution, which is 50 mL, and the time of administration, which is 15 minutes or 0.25 hours. Plugging these values into the formula, we get:
Infusion rate (mL/hr) = 50 mL / 0.25 hr
Infusion rate (mL/hr) = 200 mL/hr
Therefore, the nurse should set the IV pump to deliver 200 mL/hr. This is the answer to the question.

Correct Answer is ["38"]
Explanation
To solve this problem, the nurse needs to find the concentration of lidocaine in the solution, which is 1 g / 250 mL = 0.004 g/mL.
Then, the nurse needs to convert the dosage of lidocaine from mg/min to g/hr, which is 2.5 mg/min x 60 min/hr x 0.001 g/mg = 0.15 g/hr. Finally, the nurse needs to divide the dosage by the concentration to get the infusion rate, which is 0.15 g/hr / 0.004 g/mL = 37.5 mL/hr.
Rounding to the nearest whole number, the nurse should set the IV pump to deliver 38 mL/hr.
Correct Answer is ["0.3"]
Explanation
To calculate the dose of cefazolin for a neonate, first multiply the weight by the dosage per day: 5 kg x 40 mg/kg/day = 200 mg/day. Then divide by the number of doses per day: 200 mg/day / 2 doses/day = 100 mg/dose. Next, use the formula D/H x Q to find the volume to administer, where D is the dose, H is the strength of the solution, and Q is the quantity of the solution. Plug in the values: 100 mg / 330 mg/mL x 1 mL = 0.3 mL. Round to the nearest tenth: 0.3 mL. Therefore, the nurse should administer 0.3 mL of cefazolin per dose.
