Answer :
The solution is 206 ml, rounded to three significant numbers. As a result, each dosage requires 206 ml of medication A.
As per the question given,
First, we need to find the weight of the patient in kilograms. We know that 1 kg is equal to 2.20462 lbs, so:
145 lbs ÷ 2.20462 lbs/kg = 65.77 kg
Next, we can calculate the dose of drug A:
2.5 mg/kg × 65.77 kg = 164.43 mg
Finally, we can find how many ml of drug A need to be given per dose by dividing the dose by the supply concentration:
164.43 mg ÷ 0.80 mg/ml ≈ 205.54 ml
Rounding to three significant figures, the answer is 206 ml. Therefore, 206 ml of drug A need to be given per dose.
