#1
What is the drop factor in intravenous medication administration?
The number of drops per milliliter (gtts/mL) of the solution
ExplanationDrop factor indicates the concentration of medication in solution and determines the rate of administration.
#2
What is the primary role of the nurse in intravenous medication administration?
Monitoring patient vital signs
ExplanationThe nurse's primary role is to ensure patient safety by monitoring vital signs for any adverse reactions.
#3
What is the role of a drip chamber in intravenous administration sets?
To prevent air from entering the tubing
ExplanationThe drip chamber maintains a consistent flow by trapping air and preventing it from entering the IV tubing.
#4
When calculating the drip rate for intravenous (IV) medication, what unit is commonly used to express time?
Minutes (min)
ExplanationTime is typically expressed in minutes when calculating the drip rate for IV medication administration.
#5
What is the formula for calculating intravenous medication flow rate?
Flow rate (mL/min) = Volume (mL) / Time (min)
ExplanationFlow rate is determined by dividing the volume of medication by the time it takes to administer.
#6
How do you calculate the total volume of medication to be administered?
Total Volume = Flow rate x Infusion Time
ExplanationTotal volume is determined by multiplying the flow rate by the duration of infusion.
#7
What is the purpose of a primary intravenous (IV) set?
To administer intravenous fluids
ExplanationThe primary IV set is used to deliver fluids directly into the patient's bloodstream.
#8
When calculating intravenous medication dosage, why is it important to consider the patient's weight?
To personalize the dosage based on individual needs
ExplanationWeight-based dosing ensures medication administration tailored to the patient's specific requirements.
#9
What is the primary purpose of the intravenous (IV) push method?
To administer a large volume of medication quickly
ExplanationThe IV push method delivers medication rapidly into the bloodstream, often used for immediate therapeutic effect.
#10
When using a volumetric infusion pump, how is the flow rate typically controlled?
Setting the infusion rate on the pump
ExplanationThe flow rate is controlled by adjusting the infusion rate setting on the pump.
#11
In intravenous therapy, what is the purpose of a Y-site on an administration set?
To allow simultaneous infusion of different medications
ExplanationThe Y-site permits the concurrent administration of multiple medications or fluids into the same IV line.
#12
What is the significance of the term 'compatibility' when referring to intravenous medications?
The ability of medications to be mixed in the same solution
ExplanationCompatibility ensures that medications can be safely combined in a single solution without adverse reactions.
#13
What is the purpose of a back-priming procedure in intravenous (IV) administration?
To clear air bubbles from the tubing
ExplanationBack-priming removes air bubbles from the IV tubing to prevent air embolisms during medication administration.
#14
In intravenous (IV) therapy, what does the term 'infiltration' refer to?
The inadvertent administration of medication into surrounding tissues
ExplanationInfiltration occurs when IV medication leaks into surrounding tissues instead of entering the bloodstream.
