Correct Answer is ["0.9"]
Explanation
-
Convert the client’s weight from pounds to kilograms:
- 1 kilogram (kg) = 2.2 pounds (lb)
- Weight in kg = 187 lb / 2.2 = 85 kg
-
Calculate the dose of fentanyl in micrograms (mcg):
- Dose = 0.5 mcg/kg × 85 kg = 42.5 mcg
-
Determine the volume of fentanyl to administer:
- Available concentration is 50 mcg/ml
- Volume (ml) = Dose (mcg) / Concentration (mcg/ml)
- Volume (ml) = 42.5 mcg / 50 mcg/ml = 0.85 ml
-
Round the answer to the nearest tenth:
- Rounded volume = 0.9 ml
Correct Answer is ["2.1"]
Explanation
To calculate the amount of tobramycin to administer per dose, you need to follow these steps:
Step 1: Calculate the total daily dose. Total Daily Dose (mg) = Weight (kg) x Dose (mg/kg/day)
Total Daily Dose (mg) = 85 kg x 3 mg/kg/day = 255 mg/day
Step 2: Calculate the dose per divided dose (three divided doses). Dose per Divided Dose (mg) = Total Daily Dose (mg) / Number of Divided Doses
Dose per Divided Dose (mg) = 255 mg / 3 doses = 85 mg/dose
Step 3: Convert the dose to mL using the concentration. Dose (mL) = Dose (mg) / Concentration (mg/mL)
Dose (mL) = 85 mg / 40 mg/mL ≈ 2.125 mL
Rounded to the nearest tenth, the nurse should administer 2.1 mL per dose.
