What is the safe dosage range of a drug prescribed at 2.5 mg/kg for a 50 kg patient?

To determine the safe dosage range of a drug prescribed at 2.5 mg/kg for a 50 kg patient, you would multiply the patient's weight by the dosage per kilogram. In this case, the calculation is as follows:

2.5 mg/kg × 50 kg = 125 mg.

This result indicates that the safe total dosage for a patient who weighs 50 kg is 125 mg. Therefore, 125 mg is the correct answer. Understanding the dosage calculations is crucial in ensuring that patients receive the appropriate amount of medication based on their weight to avoid underdosing or overdosing.
