(Enter the numerical value only. If rounding is required round to the nearest hundredth)
The Correct Answer is ["0.75"]
The healthcare provider prescribes interferon beta-1b 0.1875 mg every other day for a client with multiple sclerosis.
The nurse reconstitutes the single-use vial of powder labeled 0.3 mg with 1.2 mL of sterile water, so the concentration of interferon beta-1b in the solution is 0.25 mg/mL (0.3 mg / 1.2 mL).
Since the healthcare provider prescribes 0.1875 mg of interferon beta-1b, the nurse should administer 0.75 mL of medication (0.1875 mg / 0.25 mg/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 ["120"]
Explanation
The healthcare provider prescribes a continuous infusion of labetalol at 2 mg/minute.
Labetalol HCI Injection USP 200 mg in 200 mL of 5% Dextrose Injection, USP, is delivered to the unit. This means that for every mL of the solution, there is 1 mg of labetalol (200 mg / 200 mL = 1 mg/mL).
To administer a dose of 2 mg/minute, the nurse should program the infusion pump to deliver 120 mL/hour (2 mg/minute × 60 minutes/hour = 120 mg/hour; 120 mg/hour ÷ 1 mg/mL = 120 mL/hour).
