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. Potassium 2.5 mEq/L: This is critically low (normal range is 3.5–5.0 mEq/L), and hypokalemia can cause life-threatening cardiac arrhythmias.
C. Urine specific gravity 1.025: Although elevated, it is not as critical as severe hypokalemia.
D. Blood glucose 110 mg/dL: This is a normal glucose level and not a priority.
