IV Insertion & Infusion Therapy Certification Practice Exam
Questions and Correct Answers (Verified Answers) with
Rationales 2025
1. What is the most appropriate vein for peripheral IV insertion in an adult?
• Cephalic vein
• Basilic vein
• Femoral vein
• Jugular vein
The basilic vein is superficial, accessible, and has a large lumen suitable for
peripheral IV insertion.
2. What is the primary reason for flushing an IV catheter?
• To prevent hypovolemia
• To administer medication
• To maintain patency
• To assess pain level
Flushing ensures that the catheter remains open and free of blockages.
3. Which angle should the needle be inserted when initiating a peripheral IV?
• 10 degrees
• 15–30 degrees
• 45–60 degrees
,• 75–90 degrees
An insertion angle of 15–30 degrees allows penetration into superficial veins
without going too deep.
4. What is phlebitis?
• Infection of a vein
• Inflammation of a vein
• Clot formation in an artery
• Obstruction of lymph vessels
Phlebitis is inflammation of the vein, often due to mechanical or chemical
irritation.
5. How often should a short peripheral IV site be assessed in an adult?
• Every 8 hours
• Every 4 hours
• Every shift
• Once a day
Frequent assessment helps detect complications early and ensures proper
functioning.
6. Which of the following is a sign of infiltration?
• Redness and warmth
• Swelling and coolness
• Pulsating pain
• Hardness and heat
Infiltration presents as cool, swollen tissue due to fluid leaking into surrounding
tissue.
, 7. What is the first action if an IV site becomes red and tender?
• Increase infusion rate
• Apply warm compress
• Stop the infusion
• Flush with saline
Stopping the infusion prevents further irritation and damage to the site.
8. Which is the most sterile part of the IV catheter?
• Hub
• Tip
• Wing
• Clamp
The catheter tip is inserted into the bloodstream and must remain sterile to avoid
infection.
9. What size catheter is ideal for rapid fluid resuscitation?
• 24 gauge
• 22 gauge
• 18 gauge
• 26 gauge
A larger bore like 18G allows faster fluid administration during emergencies.
10. What complication is associated with air entering the bloodstream
during IV therapy?
• Phlebitis
• Hematoma
