Question

Quizplus · Accepted Answer

To calculate the safe medication dosage, we need to convert the patient's weight from pounds to kilograms.

16.5 lb ÷ 2.2 lb/kg = 7.5 kg

Then, we can calculate the safe dosage range:

0.0075 mg/kg/day × 7.5 kg = 0.05625 mg/day

0.010 mg/kg/day × 7.5 kg = 0.075 mg/day

Therefore, a safe medication dosage would be within the range of 0.05625 mg/day to 0.075 mg/day.

Out of the answer choices, only option C (0.074 mg) falls within this safe dosage range.
