A provider prescribes furosemide 1 mg/kg/day IV push, divided into doses every 6 hours, for a patient who weighs 145 lbs. Available is 10 mg per 1 mL. What is the amount a pharmacy technician should dispense per dose in mL?

Answer :

Final answer:

For a patient weighing 145 lb, their weight in kg would be around 65.77 kg. Given that furosemide is prescribed at 1 mg/kg, they would require approximately 65.77 mg/day. This amount would then be divided into 4 doses a day, each dose being around 16.44 mg. With the available form being 10 mg/ml, each dose in mL would be about 1.644 mL.

Explanation:

To calculate the mL a pharmacy technician dispenses for a dose, we first need to convert the patient's weight to kilograms, since the medication is prescribed in mg/kg. Given that 1 lb is approximately 0.4536 kg, a person who weighs 145 lb weighs roughly 65.77 kg.

Furosemide is prescribed at 1 mg/kg, so the patient requires approximately 65.77 mg/day. To split this into doses every 6 hours (4 doses a day), each dose would be about 16.44 mg.

Since the available form is 10 mg of furosemide per 1 mL, to administer 16.44 mg, the pharmacy technician would need to dispense around 1.644 mL of the drug.
