A client is currently receiving an infusion labeled as 5% Dextrose Injection 500 mL with heparin sodium 25,000 Units at a rate of 14 mL/hour. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many mL/hour should the nurse program the infusion pump?
(Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["20"]

The client is currently receiving an infusion labeled as 5% Dextrose Injection 500 mL with heparin sodium 25,000 Units. The concentration of heparin in the IV solution is 50 units/mL (25,000 units / 500 mL).

A prescription is received to change the rate of the infusion to heparin 1,000 units/hour.

Since the concentration of heparin in the IV solution is 50 units/mL, the nurse should program the infusion pump to deliver 20 mL/hour of the IV solution (1,000 units/hour / 50 units/mL).

Correct Answer is ["1250"]

Explanation

A child weighing 25 kilograms is receiving ampicillin 300 mg/kg/24 hours intravenously in equally divided doses every 4 hours.

This means that the child is receiving a total of 7500 mg of ampicillin per day (300 mg/kg/day × 25 kg = 7500 mg/day).

Since there are 24 hours in a day and the doses are given every 4 hours, the child will receive a total of 6 doses per day (24 hours/day ÷ 4 hours/dose = 6 doses/day).

Therefore, for each dose, the nurse should administer 1250 mg of ampicillin (7500 mg/day ÷ 6 doses/day = 1250 mg/dose).

Correct Answer is ["8"]

Explanation

The total daily dose is 80 mg (20 mg x 4). Since the medication is available in 10 mg tablets, we can calculate the number of tablets required as follows:

80 mg / 10 mg per tablet = 8 tablets
