Question

The order reads: Give hydralazine (Apresoline) 0.75 mg/kg/day. The child weighs 16 pounds. How much hydralazine will be given? (Record your answer using two decimal places.)

Answer 1

To calculate the dose of hydralazine for the child, first convert the child's weight from pounds to kilograms, then multiply by the dose per kilogram. The child weighing 16 pounds would receive 5.44 mg of hydralazine per day.

Step-by-step explanation:

The question requires the calculation of a medication dosage based on the patient's weight. The initial order is for hydralazine (Apresoline) at a dose of 0.75 mg/kg/day. The child's weight is given in pounds and must be converted to kilograms before calculating the dose. There are approximately 2.20462 pounds in one kilogram.

First, let's convert the child's weight from pounds to kilograms:

16 pounds ÷ 2.20462 = 7.25748 kg (rounded to five decimal places)

Next, we calculate the daily dose of hydralazine:

7.25748 kg × 0.75 mg/kg = 5.4431 mg/day

This is the total daily dose, which can be recorded as 5.44 mg/day using two decimal places.
