A client who weighs 172 pounds receives a prescription for levothyroxine 1.6 mcg/kg/day by mouth. The medication is available in 50 mcg scored tablets. How many tablets should the nurse administer?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2.5"]
The client weighs 172 pounds which is equivalent to 78.02 kg (1 kg = 2.20462 pounds).
The prescription for levothyroxine is 1.6 mcg/kg/day, so the client should receive 124.83 mcg of levothyroxine per day (1.6 mcg/kg/day * 78.02 kg).
The medication is available in 50 mcg scored tablets, so the nurse should administer 2.5 tablets per day (124.83 mcg / 50 mcg/tablet).

Correct Answer is ["8"]
Explanation
The client is receiving an IV infusion of regular insulin 60 units in 100 mL of normal saline at 5 units/hour. The concentration of insulin in the IV solution is 0.6 units/mL (60 units / 100 mL).
Since the healthcare provider prescribes 5 units/hour of insulin, the nurse should program the infusion pump to deliver 8 mL/hour of the IV solution (5 units/hour / 0.6 units/mL).
Correct Answer is ["1930"]
Explanation
The healthcare provider prescribes an IV solution of ampicillin 1 gram in 50 mL of Dextrose in Water (D/W) at 25 drops/minute.
The nurse uses an infusion set that delivers 15 drops/mL.
This means that the infusion rate is 1.67 mL/minute (25 drops/minute ÷ 15 drops/mL = 1.67 mL/minute).
Since the total volume of the solution is 50 mL, it will take approximately 30 minutes to infuse the entire solution (50 mL
÷ 1.67 mL/minute = 30 minutes).
If the nurse starts the infusion at 1900 (7:00 PM), the infusion should be completed at approximately 1930 (7:30 PM).
