#9
17. How does the nurse calculate the time required for an IV infusion using the formula?
Time = Volume / (Infusion rate × Drop factor)
Time = (Volume × Drop factor) / Infusion rate
Time = Infusion rate / (Volume × Drop factor)

To monitor the patient's heart rate
To prevent medication errors and provide a legal record
To assess patient response
#13
25. How does the nurse calculate the total volume of an IV medication solution required for a specific time period?
Total volume = Infusion rate × Time
Total volume = Time / Infusion rate
Total volume = Infusion rate / Time
Total volume = Time × (Infusion rate + Drop factor)
#14
3. How is the drop factor of an IV administration set determined?
By the patient's weight
By the medication concentration
By the manufacturer's specifications

To determine the infusion rate using time and flow
To assess patient response to medication
To calculate drug compatibility
To measure the patient's heart rate
#16
8. What does the term 'loading dose' mean in the context of IV medication administration?
The initial higher dose given to achieve therapeutic levels quickly
The dose given at the end of the infusion
The maintenance dose during the course of treatment
The dose adjusted based on the patient's weight

#18
20. How does the nurse adjust the infusion rate when using a volumetric infusion pump for IV medication?
By manually controlling the flow rate
By adjusting the drip factor
By setting the pump parameters
By inspecting the IV tubing for air bubbles
#19
22. When administering IV medications, what does the term 'filtration' refer to?
The process of drug breakdown in the body
The passage of medication through a filter in the IV tubing
The adjustment of the drug concentration
