A nurse is preparing to administer 0.9% sodium chloride 1,200 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["150"]
Step 1 is to determine the rate of infusion. This is done by dividing the total volume by the total time. So, we have 1200 mL ÷ 8 hr = 150 mL/hr.
So, the correct answer is 150 mL/hr.

Correct Answer is ["0.8"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. Given that 1 kg = 2.2 lb, we calculate:
183 lb ÷ 2.2 = 83.18 kg
Rounding to the nearest hundredth, the client’s weight is 83.18 kg.
Step 2 is to calculate the total amount of medication needed. The prescribed dosage is 0.1 mg/kg, so we calculate:
0.1 mg/kg × 83.18 kg = 8.32 mg
Rounding to the nearest hundredth, the total medication required is 8.32 mg.
Step 3 is to determine the volume to administer. The available concentration of furosemide is 10 mg/mL, so we divide:
8.32 mg ÷ 10 mg/mL = 0.832 mL
Rounding to the nearest tenth, the correct amount to administer is 0.8 mL.
Correct Answer is ["3"]
Explanation
Step 1 is to determine the total amount of medication needed. The doctor ordered 300 mg of phenytoin and each capsule contains 100 mg. So, we divide the total amount ordered by the amount per capsule: 300 mg ÷ 100 mg/capsule = 3 capsules.
So, the correct answer is 3 capsules.
