A nurse is preparing to administer phenytoin 15 mg/kg PO as a loading dose to a client who weighs 264 lb. How many mg should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1800"]
Convert weight from pounds (lb) to kilograms (kg):
We know 1 kg is equal to 2.2 lb.
Client's weight (kg) = 264 lb / 2.2 lb/kg = 120 kg (rounded to nearest whole number)
Calculate total phenytoin dosage:
Dosage (mg) = Client's weight (kg) × Dosage per kg (mg/kg)
Dosage (mg) = 120 kg × 15 mg/kg
Dosage (mg) = 1800 mg
Round the answer to the nearest whole number:
Rounded dosage = 1800 mg
Therefore, the nurse should administer 1800 mg of phenytoin.

Therefore, the nurse should administer 1800 mg of phenytoin.
Correct Answer is ["10"]
Explanation
To calculate the correct dose of bumetanide, we need to follow these steps:
-
Determine the desired dose per tablet:
- Each tablet contains 0.5 mg of bumetanide.
-
Calculate the number of tablets needed per dose:
- Divide the desired dose (5 mg) by the dose per tablet (0.5 mg):
- 5 mg / 0.5 mg/tablet = 10 tablets
- Divide the desired dose (5 mg) by the dose per tablet (0.5 mg):
Therefore, the nurse should administer 10 tablets of bumetanide per day.
Answer: 10 tablets
