A nurse is preparing to administer lactated Ringer's 250 mL IV to infuse over 15 min.
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.). mL/hr.
The Correct Answer is ["1000"]
Step 1 is to calculate the total volume to be infused in mL/hr. This is done by dividing the total volume (250 mL) by the time in hours (15 min ÷ 60 min/hr). So, 250 mL ÷ (15 min ÷ 60 min/hr) = 1000 mL/hr.
So, the correct answer is 1000 mL/hr.

Correct Answer is ["0.4"]
Explanation
The prescribed dosage of enoxaparin is 40 mg. The available medication is in a concentration of 100 mg/mL. So, the volume to administer is 40 mg ÷ 100 mg/mL = 0.4 mL. Rounding to the nearest tenth, the nurse should administer 0.4 mL.
So, the correct answer is 0.4 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.
