Question 16 :
The healthcare provider prescribes an IV bolus of diltiazem 0.25 mg/kg for a client with atrial fibrillation. The client weighs 178 pounds. How many mg should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: ["20 mg"]
The nurse should administer 20 mg of the medication. This is because 0.25 mg/kg is the desired dose, and the client weighs 178 pounds. To convert pounds to kilograms, we divide by 2.2, so the client's weight in kilograms is 178/2.2 = 80.91 kg. Multiplying that by the desired dose gives us the amount of medication in mg: 80.91 x 0.25 = 20.23 mg. Rounding that to the nearest whole number gives us 20 mg.
