IV Therapy Certification Practice Exam
Questions and Correct Answers (Verified
Answers) with Rationales 2025
1. What is the best site for initiating a peripheral IV in an adult?
• Dorsal metacarpal veins
• Antecubital fossa
• Femoral vein
• Subclavian vein
The dorsal metacarpal veins are preferred for short-term
therapy because they are superficial and accessible.
2. When inserting an IV, what angle should the needle be inserted
initially?
• 45 degrees
• 60 degrees
• 15-30 degrees
• 5 degrees
Starting at 15-30 degrees allows proper needle entry into
the vein without puncturing through it.
3. Which of the following is a sign of infiltration?
,• Red, warm skin
• Swelling and coolness at site
• Purulent drainage
• Vein hard and cordlike
Infiltration involves fluid leaking into surrounding tissue,
causing swelling and coolness.
4. What should you do first if infiltration is suspected?
• Apply a cold compress
• Restart IV in same site
• Stop the infusion
• Inject antidote
The infusion must be stopped immediately to prevent
tissue damage.
5. What type of solution is 0.9% sodium chloride?
• Hypotonic
• Hypertonic
• Isotonic
• Colloid
0.9% NaCl has the same osmolarity as blood, making it
isotonic.
6. A patient receiving D5NS is receiving which type of solution?
• Isotonic
, • Hypotonic
• Hypertonic
• Colloid
D5NS has a higher osmolarity than blood, making it
hypertonic.
7. Phlebitis is best described as:
• Fluid accumulation under skin
• Inflammation of a vein
• Infection of IV site
• Blocked catheter
Phlebitis is vein inflammation caused by irritation or
infection.
8. Which of the following increases the risk for phlebitis?
• Low flow rate
• Poor vein-to-catheter ratio
• Short dwell time
• Frequent flushing
A large catheter in a small vein increases irritation,
causing phlebitis.
9. What size catheter is best for rapid fluid administration?
• 24 gauge
• 22 gauge
