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.)

Step 1 is to calculate the dose in milligrams (mg) per individual dose Total daily dose: 150 mg Frequency: 3 divided doses Dose per dose = 150 ÷ 3 150 ÷ 3 = 50 mg Step 2 is to identify the available concentration Available Strength: 50 mg / 5 mL Step 3 is to calculate the volume to administer in milliliters (mL) Volume = (Dose per dose ÷ Available Dose) × Available Volume Volume = (50 ÷ 50) × 5 50 ÷ 50 = 1 1 × 5 = 5 mL Step 4 is to round to the nearest whole number 5 = 5 mL Answer: 5 mL
