Answer and Explanation

The Correct Answer is ["7"]

To calculate the correct dosage of levothyroxine, the nurse should follow these steps:

Convert the patient's weight from pounds to kilograms: 220 lb ÷ 2.20462 lb/kg = 99.79 kg
Calculate the total dose of levothyroxine: 5 mcg/kg × 99.79 kg = 498.95 mcg
Determine the number of tablets to administer: 498.95 mcg ÷ 75 mcg/tablet = 6.65 tablets

Therefore, the nurse should administer 7 tablets of levothyroxine.

Explanation

To calculate the correct dosage of gentamicin for a client who weighs 154 lb, the nurse needs to perform the following steps:

- Convert the client's weight from pounds to kilograms by dividing by 2.2. 154 lb / 2.2 = 70 kg.

- Multiply the client's weight in kilograms by the prescribed dose of 1 mg/kg. 70 kg x 1 mg/kg = 70 mg.

- Divide the total dose in milligrams by the concentration of the gentamicin solution, which is 40 mg/mL. 70 mg / 40 mg/mL = 1.75 mL.

Round the final answer to the nearest tenth of a milliliter. The nurse should administer 1.8 mL of gentamicin IM to the client.
