A nurse is preparing to administer 40 mg of famotidine PO at bedtime.
If the available famotidine is 20 mg/tablet, how many tablets should the nurse administer?
The Correct Answer is ["2"]
The nurse should administer 2 tablets of famotidine. Here’s the calculation: Step 1: The total dosage required is 40 mg.
Step 2: Each tablet contains 20 mg of famotidine.
Step 3: So, the number of tablets required is 40 mg ÷ 20 mg/tablet = 2 tablets.

Correct Answer is ["15 "]
Explanation
Step 1: Convert the client’s weight from pounds to kilograms. 1 kg = 2.2 lb, so 44 lb ÷ 2.2 = 20 kg.
Step 2: Calculate the total daily dose of phenobarbital. The doctor ordered 6 mg/kg/day, so 6 mg/kg/day × 20 kg = 120 mg/day.
Step 3: Divide the total daily dose into two equal doses, as it is to be given every 12 hours. So, 120 mg/day ÷ 2 = 60 mg/dose.
Step 4: Calculate the volume of phenobarbital elixir to administer per dose. The available phenobarbital elixir is 20 mg/5 mL, so (60 mg ÷ 20 mg) × 5 mL = 15 mL. The nurse should administer 15 mL of phenobarbital elixir per dose.
Correct Answer is ["10 "]
