A nurse is preparing to administer phenelzine 90 mg PO divided in three equal doses daily to a client who has depression. Available is phenelzine 15 mg tablets. How many tablets should the nurse administer per day? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Step-by-Step Calculation Understanding the Problem Total daily dose of phenelzine: 90 mg Divided into 3 equal doses Strength of each tablet: 15 mg We need to find the total number of tablets per day. Calculations Calculate the dose per administration: Dose per administration = Total daily dose / Number of doses Dose per administration = 90 mg / 3 = 30 mg Calculate the number of tablets per dose: Tablets per dose = Dose per administration / Tablet strength Tablets per dose = 30 mg / 15 mg/tablet = 2 tablets The nurse should administer 2 tablets per day. Since the client will receive 2 tablets per dose and will take 3 doses per day, the total number of tablets for the day is: 2 tablets/dose × 3 doses/day = 6 tablets/day
