What is the total volume in milliliters needed for a 60 kg patient requiring 0.5 mg/kg of a medication?

To determine the total volume in milliliters needed for the patient, we first calculate the total dosage of the medication required for a 60 kg patient. The medication is prescribed at a rate of 0.5 mg per kilogram. Thus, we perform the following calculation:

Total dosage = patient weight (kg) × dosage per kg

Total dosage = 60 kg × 0.5 mg/kg = 30 mg

Next, we need to know the concentration of the medication in terms of mg/mL to determine the volume required. Since the answer provided is 30 mL, we can infer that the concentration of the solution is 1 mg/mL, allowing us to calculate the volume as follows:

Volume (mL) = Total dosage (mg) / Concentration (mg/mL)

Volume (mL) = 30 mg / 1 mg/mL = 30 mL

Therefore, the total volume needed for the patient is indeed 30 mL, making this calculation accurate and the answer correct.
