A nurse is preparing to administer 0.9% 1L to infuse over 8 hr. The drop factor of the manual IV tubing set is 15 gtts/ml. The nurse should set the manual IV infusion to deliver howmany gtt/min? (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 ["31"]
Flow rate (gtt/min)= Total volume / Time×Drop factor (gtt/mL)
Given:
- Total volume = 1000 mL (1 L)
- Time = 8 hours × 60 minutes = 480 minutes
- Drop factor = 15 gtt/mL
- Flow rate (gtt/min)= 1000 / 480×15= 31.25 (gtt/mL)
Answer: 31 gtt/min (rounded to the nearest whole number)

Correct Answer is D
Explanation
A. Feed the infant half-strength formula for the first 48 hr: Feeding guidelines do not typically require diluted formula unless directed by the surgeon.
B. Remove elbow restraints while the infant is sleeping: Elbow restraints should remain in place to prevent the infant from touching the surgical site, even during sleep.
C. Administer pain medication PRN for the first 48 hr: Pain medication should be administered on a regular schedule initially to control pain effectively.
D. Keep the infant in a side-lying position: This position helps protect the surgical site and minimizes the risk of aspiration.
Correct Answer is D
Explanation
A. "The operation will straighten out the kink in the intestine.": Hirschsprung’s disease involves a lack of nerve cells in the colon, not a physical kink.
B. "I want to learn how to use the feeding tube as soon as possible.": Feeding tubes are not a standard part of treatment for Hirschsprung’s disease.
C. "I’m glad my child will have bowel movements now.": While the surgery will help bowel function, the initial goal is creating an ostomy to divert stool.
