Imipramine 200 mg PO daily divided equally every 12 hours. The amount available is Imipramine 25 mg tablets. How many tablets should the nurse administer with each dose?

• A. 2 Tablets
• B. 3 Tablets
• C. 4 Tablets
• D. 5 Tablets

Answer: (C)

When a daily dose is given in two equal doses, you first find the amount to give at each administration. 200 mg per day divided into two doses equals 100 mg per dose. With tablet strength 25 mg, each 100 mg dose requires 100 ÷ 25 = 4 tablets. So, administer 4 tablets with each 12-hour dose (8 tablets total per day).
