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 A
Explanation
A. Urine specific gravity 1.034: This indicates concentrated urine, a sign of dehydration.
B. Distended neck veins: This is a sign of fluid overload, not dehydration.
C. BP 146/94 mm Hg: Hypertension is not a typical sign of dehydration; instead, dehydration often leads to low blood pressure.
D. Bounding pulse: Dehydration typically causes a weak, thready pulse rather than a bounding one.
Correct Answer is D
Explanation
A. Counting the number of wet diapers every shift: While useful, daily weight provides a more precise measure of fluid balance.
B. Taking the infant's vital signs every 2 hr: Vital signs alone do not provide as direct a measure of fluid balance as daily weight.
C. Measuring the infant's head circumference twice per day: Head circumference is unrelated to hydration status.
D. Weighing the infant at the same time every day: Daily weight is the most accurate indicator of fluid status in infants.
