A nurse is preparing to administer lactated Ringer's 500 mL IV to infuse over 4 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 ["125"]
To calculate the infusion rate for lactated Ringer's solution, the nurse should divide the total volume of fluid by the total time of infusion.
In this case, the nurse should divide 500 mL by 4 hr, which equals 125 mL/hr.
Therefore, the nurse should set the IV pump to deliver 125 mL/hr of lactated Ringer's solution.

Explanation
To calculate the dose of mycostatin oral suspension, the nurse needs to divide the prescribed amount of units by the concentration of units per mL.
In this case, the nurse should divide 400,000 units by 100,000 units/mL, which gives 4 mL.
The nurse should administer 4 mL of mycostatin oral suspension every 6 hours as ordered.
Correct Answer is ["D","E"]
Explanation
A. Administer the medication twice daily. - No, the prescription states 50 mg PO TID (three times a day), not twice daily.

C. Administer the medication 2 hours after meals. - No, the prescription advises taking it with food, not after meals.
D. Administer a loading dose of 100 mg PO. - Yes, the initial dose is 100 mg PO now.
