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.

Explanation
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 ["2"]
Explanation
Step 1 is to determine the amount of medication in 1 mL after reconstitution. This is calculated by dividing the total available medication (1000 mg) by the total volume after reconstitution (3.4 mL):
1000 mg ÷ 3.4 mL = 294.12 mg/mL
Step 2 is to determine how many mL are needed to obtain 500 mg. This is done by dividing the required dose (500 mg) by the concentration (294.12 mg/mL):
500 mg ÷ 294.12 mg/mL = 1.7 mL
Rounding to the nearest whole number, the correct amount to administer is 2 mL.
