The Correct Answer is ["20 "]
Given:
- Desired dose of megestrol: 800 mg
- Available strength of megestrol suspension: 40 mg/mL
First, find out how many milliliters of megestrol suspension correspond to the desired dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 800 mg / 40 mg/mL Volume (mL) = 20 mL

Correct Answer is ["1.8"]
Explanation
Given:
- Desired dose of gentamicin: 1 mg/kg
- Client's weight: 154 lb
- Available strength of gentamicin solution: 40 mg/mL
First, convert the client's weight from pounds to kilograms:
154 lb ÷ 2.2= 70kg
Now, calculate the desired dose of gentamicin:
Desired dose = Dosage per kg × Weight Desired dose = 1 mg/kg × 670 kg Desired dose = 70 mg
Now, find out how many milliliters of gentamicin correspond to this dose: Volume (mL) = Desired dose / Concentration
Volume (mL) = 70 mg / 40 mg/mL Volume (mL) ≈ 1.75mL
rounded off to the nearest tenths= 1.8ml
