A nurse is preparing to administer phenobarbital 6 mg/kg/day PO divided in equal doses every 12 hr to a client who weighs 44 lb. If the available phenobarbital elixir is 20 mg/5 mL, how many mL should the nurse administer per dose?

Answer and Explanation

The Correct Answer is ["15 "]

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 ["14 "]

Explanation

The medication should be discarded 14 days after reconstitution. This is a standard guideline for most reconstituted medications to ensure potency and prevent bacterial growth.

Correct Answer is ["1000 "]

Explanation

Step 1 is to calculate the total volume to be infused in mL/hr. This is done by dividing the total volume (250 mL) by the time in hours (15 min ÷ 60 min/hr). So, 250 mL ÷ (15 min ÷ 60 min/hr) = 1000 mL/hr.

So, the correct answer is 1000 mL/hr.
