Correct Answer is ["83 mL\/hr"]
Explanation
Step 1 is to calculate the total volume to be infused. The total volume is 1 L, which is equal to 1000 mL. Step 2 is to divide the total volume by the total time. The total time is 12 hours. So, the calculation is 1000 mL ÷ 12 hr = 83.33 mL/hr.
So, the correct answer is 83 mL/hr, after rounding to the nearest whole number.
Correct Answer is ["48 mL"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the medication dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lb. So, 210 lb ÷ 2.2 = 95.45 kg (rounded to the nearest hundredth). Step 2 is to calculate the total amount of medication needed using the formula: dose (mg/kg) × weight (kg). So, 5 mg/kg × 95.45 kg = 477.27 mg (rounded to the nearest hundredth). Step 3 is to calculate the volume to administer using the formula: total medication needed (mg) ÷ concentration (mg/mL). So, 477.27 mg ÷ 10 mg/mL = 47.73 mL. Rounding off to the nearest whole number, the nurse should administer 48 mL of gentamicin.
