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.)

Answer and Explanation

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 ["57"]

Explanation

Step 1 is to convert the client’s weight from pounds to kilograms. We know that 1 kg is approximately 2.2 lb. So, the client’s weight in kg is 178 lb ÷ 2.2 lb/kg = 80.91 kg. Step 2 is to calculate the total dose of acetylcysteine. The total dose is 140 mg/kg × 80.91 kg = 11327.4 mg. Step 3 is to calculate the volume to administer. The volume is 11327.4 mg ÷ 200 mg/mL = 56.637 mL.

So, the correct answer is 57 mL after rounding to the nearest whole number.

Correct Answer is ["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 200 mg ÷ 40 mg/mL = 5 mL.

So, the correct answer is 5 mL.
