A nurse is preparing to administer hydrochlorothiazide 150 mg Po daily in 3 equally divided doses.
Available is hydrochlorothiazide oral solution 50 mg/5 mL. How many mL should the nurse administer per dose? (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"]
Step 1 is to calculate the total daily dose. The total daily dose is 150 mg. Step 2 is to divide the total daily dose by the number of doses. The number of doses is 3. So, the calculation is 150 mg ÷ 3 = 50 mg/dose. Step 3 is to calculate the volume to administer using the available medication concentration. The available medication concentration is 50 mg/5 mL. So, the calculation is 50 mg ÷ (50 mg/5 mL) = 5 mL.
So, the correct answer is 5 mL, after rounding to the nearest whole number.

Correct Answer is ["0.5"]
Explanation
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 12.5 mg ÷ 25 mg/mL = 0.5 mL.
So, the correct answer is 0.5 mL.
Correct Answer is ["0.8"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. Given that 1 kg = 2.2 lb, we calculate:
183 lb ÷ 2.2 = 83.18 kg
Rounding to the nearest hundredth, the client’s weight is 83.18 kg.
Step 2 is to calculate the total amount of medication needed. The prescribed dosage is 0.1 mg/kg, so we calculate:
0.1 mg/kg × 83.18 kg = 8.32 mg
Rounding to the nearest hundredth, the total medication required is 8.32 mg.
Step 3 is to determine the volume to administer. The available concentration of furosemide is 10 mg/mL, so we divide:
8.32 mg ÷ 10 mg/mL = 0.832 mL
Rounding to the nearest tenth, the correct amount to administer is 0.8 mL.
