(Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["75"]

The healthcare provider prescribes an IV solution of isoproterenol 1 mg in 250 mL of Dextrose in Water (D/W) at a rate of 300 mcg/hour.

Since 1 mg is equivalent to 1000 mcg, the concentration of isoproterenol in the IV solution is 4 mcg/mL (1000 mcg / 250 mL).

Since the healthcare provider prescribes 300 mcg/hour of isoproterenol, the nurse should program the infusion pump to deliver 75 mL/hour of the IV solution (300 mcg/hour / 4 mcg/mL).

Correct Answer is ["1200"]

Explanation

A child who weighs 66 pounds receives a prescription for amoxicillin 80 mg/kg/day by mouth in divided doses every 12 hours.

Since 1 kg is equal to 2.2 pounds, the child weighs approximately 30 kg (66 pounds ÷ 2.2 pounds/kg = 30 kg).

This means that the child is receiving a total of 2400 mg of amoxicillin per day (80 mg/kg/day × 30 kg = 2400 mg/day).

Since there are 24 hours in a day and the doses are given every 12 hours, the child will receive a total of 2 doses per day (24 hours/day ÷ 12 hours/dose = 2 doses/day).

Therefore, for each dose, the nurse should administer 1200 mg of amoxicillin (2400 mg/day ÷ 2 doses/day = 1200 mg/dose).

Correct Answer is ["22"]

Explanation

The client receives a prescription for heparin sodium 20,000 Units in 5% dextrose injection 500 mL to be infused at a rate of 880 units/hour.

The concentration of heparin in the IV solution is 40 units/mL (20,000 units / 500 mL).

Since the healthcare provider prescribes 880 units/hour of heparin, the nurse should program the infusion pump to deliver 22 mL/hour of the IV solution (880 units/hour / 40 units/mL).
