A nurse is preparing to administer megestrol 200 mg PO to a client. Available is megestrol oral suspension 40 mg/mL. How many ml should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["5"]
To calculate the volume of megestrol oral suspension (in milliliters, mL) that the nurse should administer, use the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
In this case, the dose is 200 mg of megestrol, and the concentration of the oral suspension is 40 mg/mL.
Volume (mL) = 200 mg / 40 mg/mL
Volume (mL) = 5 mL
The nurse should administer 5 mL of megestrol oral suspension to the client.

Correct Answer is ["48"]
Explanation
To calculate how many milliliters (ml) of gentamicin to administer, follow these steps:
Calculate the client's weight in kilograms: Weight in kilograms = Weight in pounds / 2.2
Weight in kilograms = 210 lb / 2.2 Weight in kilograms ≈ 95.45 kg
Determine the dose based on the weight: Dose = 5 mg/kg × Weight in kilograms Dose = 5 mg/kg × 95.45 kg Dose ≈ 477.25 mg
Check the concentration of the available gentamicin: Concentration = 10 mg/mL
Calculate the volume (ml) to administer: Volume (ml) = Dose (mg) / Concentration (mg/ml) Volume (ml) = 477.25 mg / 10 mg/ml Volume (ml) ≈ 47.73 ml
Rounded to the nearest whole number, the nurse should administer approximately 48 ml of gentamicin.
Correct Answer is ["1.2"]
Explanation
To calculate the mL of phenobarbital to administer per dose, you can use the following steps:
Convert the client's weight from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram.
Weight in kg = 165 lb / 2.2 lb/kg ≈ 75 kg
Calculate the total daily dose based on the client's weight and the prescribed dose per kilogram:
Total daily dose = 2 mg/kg/day × 75 kg ≈ 150 mg/day
Since the dose is divided into two equal doses per day, calculate the dose per dose:
Dose per dose = Total daily dose / 2 = 150 mg / 2 = 75 mg
Now, you need to find out how many mL of phenobarbital 65 mg/mL corresponds to a dose of 75 mg:
Volume (mL) = Dose (mg) / Concentration (mg/mL) = 75 mg / 65 mg/mL ≈ 1.1538 mL
Rounded to the nearest tenth, the nurse should administer approximately 1.2 mL of phenobarbital per dose.
