Question

A 125 lb patient is to receive a drug rate of 0.300 mg per 1.00kg of body weight. If the drug is supplied as a solution containing 5.00mg/mL, how many milliliters of drug solution should the patient receive

Answer 1

To calculate the number of milliliters of the drug solution that the patient should receive, follow these steps:

Step 1: Convert the patient's weight from pounds to kilograms.
1 lb = 0.453592 kg

125 lb * 0.453592 kg/lb = 56.699 kg (rounded to three decimal places)

Step 2: Calculate the required dosage based on the patient's weight.
Dosage = (Patient's weight in kg) * (Dosage rate in mg/kg)
Dosage = 56.699 kg * 0.300 mg/kg = 17.0097 mg (rounded to four decimal places)

Step 3: Determine the volume of the drug solution required.
Volume (in mL) = (Dosage in mg) / (Concentration of the drug solution in mg/mL)
Volume = 17.0097 mg / 5.00 mg/mL

Volume = 3.40194 mL (rounded to five decimal places)

The patient should receive approximately 3.402 mL of the drug solution.
