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)

B. Increased sodium level: Electrolyte imbalances in pyloric stenosis typically involve hypochloremia and metabolic alkalosis, not increased sodium.
C. Absent bowel sounds: Bowel sounds are usually present unless there is severe dehydration or ileus.
D. Projectile vomiting after feedings: Projectile vomiting is a classic symptom of pyloric stenosis due to obstruction.
Correct Answer is C
Explanation
A. Orally: Oral temperature measurement is generally not suitable for a 1-year-old because they are often not able to cooperate, but it is not contraindicated for the child.
B. Tympanic: Tympanic (ear) temperature measurement is acceptable in children over 3 months old and is non-invasive.
C. Rectal: Rectal temperature should be avoided in infants and toddlers with diarrhea due to the risk of rectal trauma and infection. Diarrhea may also cause irritation to the rectal area, increasing the risk of injury.
D. Axillary: Axillary (underarm) temperature measurement is safe and commonly used in children, particularly for non-invasive monitoring.
