Section 6: Fundamentals of IV Therapy CNJNE IV
Certification Exam Practice Questions (100 Q&A
with Rationales)
1. What is the primary purpose of an intravenous (IV) line?
A. To provide a route for oral medication administration
B. To deliver fluids and medications directly into the bloodstream
C. To monitor blood pressure continuously
D. To provide nutritional support only
Answer: B
Rationale: IV therapy delivers fluids, electrolytes, medications, and blood
products directly into the bloodstream, ensuring rapid and controlled delivery.
2. Which vein is most commonly used for peripheral IV insertion?
A. Jugular vein
B. Femoral vein
C. Cephalic vein
D. Subclavian vein
Answer: C
Rationale: The cephalic vein is commonly used for peripheral IV access due to its
accessibility and size.
,3. What gauge needle is typically used for routine adult IV therapy?
A. 18-22 gauge
B. 14-16 gauge
C. 24-26 gauge
D. 10-12 gauge
Answer: A
Rationale: 18-22 gauge needles are commonly used for routine IV therapy in
adults, balancing flow rate and patient comfort.
4. What is the primary risk of using a smaller gauge (higher number) needle for
IV therapy?
A. Increased risk of infection
B. Reduced flow rate of fluids
C. Increased patient discomfort
D. Increased risk of infiltration
Answer: B
Rationale: Smaller gauge needles restrict the flow rate of fluids, which may be
inadequate for some therapies.
5. What is the best site to avoid when inserting an IV in a patient with diabetes?
A. Dorsal hand veins
B. Inner forearm veins
, C. Areas with scarring or edema
D. Antecubital fossa
Answer: C
Rationale: Avoid areas with scarring, edema, or compromised circulation as they
increase the risk of complications.
6. How often should a peripheral IV site be assessed for complications?
A. Every 4 hours
B. Every hour
C. Every 8 hours
D. Once daily
Answer: A
Rationale: Regular assessment every 4 hours helps early identification of
infiltration, phlebitis, or infection.
7. What is infiltration?
A. Inflammation of the vein wall
B. Leakage of IV fluid into surrounding tissue
C. Infection at the insertion site
D. Formation of a blood clot
Answer: B
Rationale: Infiltration occurs when IV fluids leak into the surrounding tissue
instead of the vein.
