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.)

Answer and Explanation

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.

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

Therefore, the nurse should administer 10 tablets of bumetanide per day.

Answer: 10 tablets

Correct Answer is ["1.8"]

Explanation

Here's the breakdown:

Convert client weight to kilograms (kg):

Client weight (kg) = Client weight (lb) / 2.2 lb/kg

Client weight (kg) = 154 lb / 2.2 lb/kg

Client weight (kg) ≈ 70 kg (rounded to nearest whole number)

Calculate desired gentamicin dose in milligrams (mg):

Desired dose (mg) = Client weight (kg) x Dose per kg

Desired dose (mg) = 70 kg x 1 mg/kg

Desired dose (mg) = 70 mg

Determine the volume of gentamicin solution to administer:

Concentration of available solution: 40 mg/mL

Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)

Volume to administer (mL) = 70 mg / (40 mg/mL)

Volume to administer (mL) = 1.75 mL (round to nearest tenth)

Therefore, the nurse should administer 1.8 mL of the gentamicin solution.
