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.)
Answer and Explanation

The Correct Answer is ["5"]

Step 1 is to determine the amount of medication needed. This is done by dividing the desired dose by the available dose. So, we have 200 mg ÷ 40 mg/mL = 5 mL. 

So, the correct answer is 5 mL.

Correct Answer is ["1.2"]

Explanation

Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is ordered in mg/kg. There are approximately 2.2 lb/kg, so 165 lb ÷ 2.2 lb/kg = 75 kg. The doctor ordered phenobarbital at a dosage of 2 mg/kg/day divided into 2 equal doses, so we multiply the client’s wei

Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. Given that 1 kg = 2.2 lb, we calculate:

165 lb ÷ 2.2 lb/kg = 75 kg

Step 2 is to determine the total daily dose of phenobarbital. The doctor ordered 2 mg/kg/day, divided into 2 equal doses. So, we first calculate the total daily dose:

75 kg × 2 mg/kg/day = 150 mg/day

Since the medication is to be given in 2 equal doses, we divide:

150 mg/day ÷ 2 = 75 mg/dose

Step 3 is to determine the volume to administer. The medication has a concentration of 65 mg/mL, so we divide the required dose by the concentration:

75 mg ÷ 65 mg/mL = 1.15 mL

Rounding to the nearest tenth, the correct amount to administer is 1.2 mL.

ght in kg by the dosage and divide by 2: (75 kg × 2 mg/kg/day) ÷ 2 = 75 mg/dose. The medication is available at a concentration of 65 mg/mL, so we divide the total mg needed per dose by the mg per mL: 75 mg ÷ 65 mg/mL = 1.15 mL.

So, the correct answer is 1.2 mL.

Correct Answer is ["8"]

Explanation

Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is ordered in units/kg. There are approximately 2.2 lb/kg, so 130 lb ÷ 2.2 lb/kg = 59.1 kg. The doctor ordered calcitonin at a dosage of & units/kg, so we multiply the client’s weight in kg by the dosage: 59.1 kg × & units/kg = & units. The medication is available at a concentration of 200 units/mL, so we divide the total units needed by the units per mL: & units ÷ 200 units/mL = & mL.

So, the correct answer is 8mL.
