Correct Answer is ["2"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. So, the client’s weight in kg is 175 lb ÷ 2.2 lb/kg = 79.55 kg. Step 2 is to calculate the total dose of lorazepam. The total dose is 0.05 mg/kg × 79.55 kg = 3.9775 mg. Step 3 is to calculate the volume to administer. The volume is 3.9775 mg ÷ 2 mg/mL = 1.98875 mL.
So, the correct answer is 2 mL after rounding to the nearest whole number.
Correct Answer is ["83"]
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.
