The nurse should administer 2.5 tablets of prednisone. Here’s the calculation: Step 1: The total dosage required is 50 mg.

Step 2: Each tablet contains 20 mg of prednisone.

Step 3: So, the number of tablets required is 50 mg ÷ 20 mg/tablet = 2.5 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 ["1.57 "]

Explanation

Step 1: Calculate the dose of lorazepam. The doctor ordered 0.05 mg/kg, so 0.05 mg/kg × 62.73 kg (138 lb ÷ 2.2 lb/kg) = 3.14 mg.

Step 2: Calculate the volume of lorazepam injection to administer. The available lorazepam injection is 2 mg/mL, so 3.14 mg ÷ 2 mg/mL = 1.57 mL. The nurse should administer 1.57 mL of lorazepam injection.
