A patient weighing 159 lbs needs to receive a dose of 2.5 mg per kg of body weight. The concentration of the drug is 10 mg per ml. How many ml should this patient receive for the correct dosage?

Answer :

The patient should be administered approximately 18.03 ml to achieve the correct dosage with determining the volume of the drug required by dividing the dosage by the concentration.

We must first change the patient's weight from pounds to kilogrammes in order to calculate the dosage. Given that 1 lb is about equivalent to 0.4536 kg, the patient weighs 159 pounds, which is equivalent to 72.12 kg (159 pounds 0.4536 kg/lb).

The needed dose per kilogramme is multiplied by the patient's weight in kilogrammes to determine the dosage. Given that the dosage in this instance is 2.5 mg per kilogramme, the dosage equals around 72.12 kg multiplied by 2.5 mg/kg, or 180.3 mg.

Since the medication's concentration is specified as 10 mg per ml, we can calculate the volume of medication needed by dividing the dosage by the medication's concentration. To reach the proper dosage, the patient should therefore take roughly [tex]\frac{180.3}{10}[/tex] = 18.03 ml.
