A nurse is preparing to administer 0.9% sodium chloride 1,000 mL IV to infuse over 4 hr. The drop factor on the manual tubing is 12 gtt/mL. The nurse should regulate the flow rate to deliver how many 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 ["50"]
To calculate the flow rate in drops per minute (gtt/min), you can use the formula:
Flow rate (gtt/min) = Volume (mL) × Drop factor (gtt/mL) ÷ Time (min)
Given:
Volume = 1000 mL
Drop factor = 12 gtt/mL
Time = 4 hours
Convert 4 hours to minutes:
4 hours × 60 minutes/hour = 240 minutes
Then
Flow rate (gtt/min) = 1000 mL × 12 gtt/mL ÷ 240 min
Flow rate (gtt/min) = 12000 gtt ÷ 240 min
Flow rate (gtt/min) = 50 gtt/min
Therefore, the nurse should regulate the flow rate to deliver 50 gtt/min.

Correct Answer is C
Explanation
Choice A rationale: Phenytoin is an anticonvulsant medication that is used to treat seizures. It can be given orally or intravenously, but the IV route requires careful preparation and monitoring. According to the medication label, the phenytoin is in form of an oral suspension hence it should be administered orally.
Choice B rationale: the total amount available per container is usually 5 mL not 4 mL. Choice C rationale: Phenytoin suspension should not be shaken, as it may cause the drug to precipitate. Shaking it could lead to inaccurate dosing.
Choice D rationale: The medication should also be stored at room temperature and protected from light.
Correct Answer is ["60"]
Explanation
To calculate the infusion rate of lidocaine, we need to convert the dose from mg/min to mg/hr and then to mL/hr.
The prescribed dose is 4 mg/min, so the hourly dose is 4 x 60 = 240 mg/hr.
The concentration of the drug is 1 g in 250 mL, which is equivalent to 1000 mg in 250 mL or 4 mg in 1 mL.
Therefore, the volume per hour is 240 / 4 = 60 mL/hr.
Rounded to the nearest whole number, the nurse should set the IV pump to deliver 60 mL/hr.
