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)

C. Heart rate 130/min: Tachycardia indicates ongoing dehydration or stress.
D. Capillary refill greater than 3 seconds: Prolonged capillary refill suggests inadequate perfusion and continued dehydration.
Correct Answer is B
Explanation
A. "I am hungry and thirsty.": Hunger and thirst are not concerning and may occur after fasting or due to nausea resolution.
B. "My belly doesn't hurt anymore.": A sudden decrease in abdominal pain may indicate rupture of the appendix, leading to peritonitis—a life-threatening emergency.
C. "I am scared and I want to go home.": This is a common emotional response in children facing surgery and not indicative of a medical emergency.
D. "I'm tired and want to take a nap.": Fatigue could result from illness but is less concerning than the potential for appendiceal rupture.
