Section 2: Fundamentals of IV Therapy — CNJNE IV
Certification Exam 2025
Total Questions: 100 | Format: Multiple Choice |
Answers & Rationales Included
1. What is the primary purpose of intravenous (IV) therapy?
A. To prevent infection
B. To administer oral medications
C. To deliver fluids, medications, or nutrients directly into the bloodstream
D. To regulate blood pressure
Answer: C
Rationale: IV therapy is primarily used to provide fluids, medications, or nutrients
directly into the bloodstream for fast and controlled administration.
2. Which of the following veins is most commonly used for peripheral IV access
in adults?
A. Femoral vein
B. Jugular vein
C. Basilic vein
D. Median cubital vein
Answer: D
Rationale: The median cubital vein is commonly used for venipuncture due to its
size, accessibility, and relatively low risk of complications.
,3. When selecting a vein for IV insertion, which of the following should be
avoided?
A. Veins in the non-dominant arm
B. Veins that feel soft and bouncy
C. Veins near areas of flexion such as the wrist
D. Straight veins
Answer: C
Rationale: Areas of flexion increase the risk of dislodgement and infiltration due
to movement.
4. What gauge catheter is typically used for trauma or rapid fluid resuscitation?
A. 24G
B. 22G
C. 20G
D. 14G
Answer: D
Rationale: A large-bore (14G) catheter is used in emergency or trauma settings to
allow rapid infusion of fluids or blood products.
5. The most appropriate IV solution to treat hypovolemia is:
A. D5W
B. 0.9% Normal Saline
C. 0.45% Saline
D. D5NS
Answer: B
Rationale: 0.9% Normal Saline is an isotonic solution ideal for volume
replacement.
, 6. Which of the following best describes isotonic solutions?
A. Draw fluid from cells into circulation
B. Have the same osmolality as plasma
C. Cause cells to shrink
D. Are not used in volume expansion
Answer: B
Rationale: Isotonic fluids have the same tonicity as plasma, making them ideal for
volume replacement without shifting fluids between compartments.
7. What complication is characterized by cool skin, swelling, and lack of blood
return from an IV site?
A. Phlebitis
B. Infiltration
C. Embolism
D. Septicemia
Answer: B
Rationale: Infiltration occurs when IV fluid leaks into surrounding tissue due to
catheter dislodgement or vein rupture.
8. A red, tender vein with a palpable cord indicates:
A. Infiltration
B. Infection
C. Phlebitis
D. Occlusion
Answer: C
Rationale: Phlebitis is inflammation of the vein, often indicated by redness,
tenderness, and a palpable cord.
9. Which of the following is the most important step before initiating IV
therapy?
