A nurse is preparing to administer 0.9% NaCl 750 mL IV to infuse over 4 hours. The drop factor of the manual IV tubing is 10 gtt/mL. What is the flow rate in gtt/min? (Round to the nearest whole number & fill in the blank with the numerical value only).
The Correct Answer is ["31"]
Total volume to be infused = 750 mL
Total infusion time = 4 hours
Convert hours to minutes: 4 hours × 60 minutes/hour = 240 minutes
Drop factor = 10 gtt/mL
- Calculate the total number of drops needed:
Total drops (gtt) = Total volume (mL) × Drop factor (gtt/mL)
= 750 mL × 10 gtt/mL
= 7500 gtt
- Calculate the flow rate in drops per minute (gtt/min):
Flow rate (gtt/min) = Total drops (gtt) / Total infusion time (minutes)
= 7500 gtt / 240 minutes
= 31.25 gtt/min
- Round to the nearest whole number:
Rounding 31.25 to the nearest whole number gives 31.
= 31 gtt/min.

Correct Answer is A
Explanation
A. "Increase your fluid intake to 2–3 liters per day.": Increased fluid intake helps dilute uric acid levels and promotes renal excretion, reducing the risk of kidney stones—a common complication in patients taking allopurinol. Maintaining hydration is a key part of long-term gout management.
B. "Discontinue the medication once symptoms improve.": Allopurinol is a maintenance medication meant to prevent gout flares by lowering uric acid levels over time. Stopping it when symptoms improve can lead to rebound hyperuricemia and recurrent attacks.
C. "Double the dose if a dose is missed.": Doubling a missed dose can increase the risk of toxicity, including skin rash, liver dysfunction, and hypersensitivity reactions. If a dose is missed, it should be taken as soon as remembered unless it's almost time for the next dose.
D. "Take the medication only during acute gout attacks.": Allopurinol is not intended for acute gout relief; it can actually worsen or trigger flares when initiated during an attack. It is used for chronic urate-lowering therapy and should be taken consistently.
Correct Answer is ["480"]
Explanation
Given quantity = 16 ounces
Desired unit = mL (milliliters)
Convert from ounces to millilitres
1 ounce = 30 mL
16 ounces × 30 mL/ounce
= 480 mL
