PREPARE Section 3: Fundamentals of IV Therapy
CNJNE IV Certification Exam 2024 - 100 Questions
and answers with rationales
1. What is the primary goal of IV therapy?
A. Deliver medication orally
B. Maintain or restore fluid and electrolyte balance
C. Reduce the need for vital sign monitoring
D. Prevent the need for blood tests
Rationale: IV therapy restores and maintains fluid/electrolyte balance.
2. Which of the following veins is most commonly used for peripheral IV
insertion?
A. Femoral vein
B. Cephalic vein
C. Pulmonary vein
D. Brachiocephalic vein
Rationale: The cephalic vein is easily accessible and commonly used.
3. What is the correct angle of insertion for a peripheral IV catheter?
,A. 10–15 degrees
B. 15–30 degrees
C. 45–60 degrees
D. 90 degrees
Rationale: A 15–30° angle allows proper entry into superficial veins.
4. Which solution is isotonic?
A. 0.45% NaCl
B. 0.9% NaCl
C. D5W
D. 3% NaCl
Rationale: 0.9% Normal saline is isotonic and used for volume expansion.
5. What complication is associated with IV fluid leaking into the surrounding
tissue?
A. Phlebitis
B. Infection
C. Infiltration
D. Thrombosis
Rationale: Infiltration involves fluid escaping into tissues.
6. What symptom is most associated with phlebitis?
, A. Sweating
B. Redness, warmth, and pain along the vein
C. Pale skin
D. Itching at the site
Rationale: Classic signs of inflammation in the vein.
7. Which action best prevents air embolism during IV therapy?
A. Using a butterfly needle
B. Administering bolus rapidly
C. Using a 25-gauge needle
D. Priming the IV tubing completely
Rationale: Priming removes air from tubing to avoid embolism.
8. What does TKO stand for in IV therapy?
A. Total Kinetic Output
B. Therapeutic KCl Output
C. To Keep Open
D. Tube Keeps Open
Rationale: TKO maintains IV access with minimal fluid flow.
9. What is the main indication for using a central venous catheter?
A. Short-term therapy
B. Long-term medication or TPN administration
