Final answer:

To calculate the volume of hydralazine to administer, convert the patient's weight to kilograms, calculate the total dose required, and divide by the medication's concentration. The nurse should administer 0.4 mL of hydralazine to the patient. the correct answer is D

Explanation:

The question involves calculating the volume of medication to administer based on the patient's weight and the concentration of the medication available. First, we need to convert the patient's weight from pounds to kilograms, knowing that 1 pound is approximately 0.453592 kilograms. Then, we use the patient's weight in kilograms and the prescribed dose in mg/kg to find the total dose in milligrams. Finally, we divide the total dose by the concentration of the medication available to find the volume to administer in milliliters.

The patient weighs 84 lb. To convert this to kilograms: 84 lb × 0.453592 = 38.11 kg (approximately). The prescribed dose is 0.2 mg/kg, so the total dose required is 38.11 kg × 0.2 mg/kg = 7.622 mg. With the medication available at 20 mg/mL, the volume to administer is 7.622 mg ÷ 20 mg/mL = 0.38 mL. When rounded to the nearest hundredth, this is 0.4 mL.
