Available is hydrochlorothiazide oral solution is 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.) Explanation Correct Answer: 5 Determine the single dose: Total daily dose = 150 mg Divided into 3 equal doses = 150 mg / 3 = 50 mg per dose Determine the volume to administer: Available concentration = 50 mg/5 mL Desired dose = 50 mg Volume to administer = (Desired dose / Available concentration) * Volume per dose Volume to administer = (50 mg / 50 mg/mL) * 5 mL = 5 mL Therefore, the nurse should administer 5 mL per dose.
