1. Which of the following is the primary purpose of intravenous
(IV) therapy?
A. To provide oxygen directly to the lungs
B. To administer fluids, medications, and nutrients directly into the
bloodstream
C. To monitor heart rhythms continuously
D. To replace surgical dressings
Answer: B. To administer fluids, medications, and nutrients directly
into the bloodstream
Rationale: Intravenous therapy allows fluids, medications, electrolytes,
blood products, and nutrients to enter the bloodstream quickly and
efficiently. This route is often used when rapid absorption or precise
control of therapy is necessary.
2. Which vein is commonly used for peripheral IV insertion in
adults?
A. Femoral vein
B. Radial artery
C. Cephalic vein
D. Carotid artery
,Answer: C. Cephalic vein
Rationale: The cephalic vein is one of the most commonly used veins
for peripheral IV insertion because it is accessible, visible, and
relatively stable. Arteries are not used for routine IV therapy.
3. What is the most important action before initiating IV
therapy?
A. Applying a heat pack
B. Verifying the provider’s order
C. Elevating the patient’s legs
D. Removing all patient clothing
Answer: B. Verifying the provider’s order
Rationale: Verifying the healthcare provider’s order ensures that the
correct fluid, medication, rate, and route are administered safely. This
is a critical safety step before beginning IV therapy.
4. Which IV solution is considered isotonic?
A. 0.45% normal saline
B. Dextrose 10% in water
C. 0.9% normal saline
D. 3% saline
Answer: C. 0.9% normal saline
Rationale: Isotonic solutions have a similar osmolarity to blood
plasma and do not cause significant fluid shifts between cells and the
bloodstream. Normal saline 0.9% is a common isotonic solution.
5. A nurse notices swelling and coolness around an IV site. What
complication should the nurse suspect?
,A. Phlebitis
B. Infiltration
C. Hematoma
D. Infection
Answer: B. Infiltration
Rationale: Infiltration occurs when IV fluid leaks into surrounding
tissue. Common signs include swelling, coolness, pallor, and
discomfort at the insertion site.
6. Which action helps prevent infection during IV insertion?
A. Reusing gloves
B. Using clean technique only
C. Performing hand hygiene before the procedure
D. Touching the insertion site after cleaning
Answer: C. Performing hand hygiene before the procedure
Rationale: Proper hand hygiene is one of the most effective ways to
prevent infection and reduce the transmission of microorganisms
during IV therapy.
7. What is the recommended angle for inserting a peripheral IV
catheter?
A. 5 degrees
B. 10 to 30 degrees
C. 45 to 60 degrees
D. 90 degrees
Answer: B. 10 to 30 degrees
Rationale: Inserting the catheter at a 10-to-30-degree angle helps
access the vein safely while minimizing trauma to surrounding tissues.
, 8. Which gauge catheter is most appropriate for rapid blood
transfusion?
A. 24-gauge
B. 22-gauge
C. 20-gauge
D. 14-gauge
Answer: D. 14-gauge
Rationale: Larger-bore catheters such as a 14-gauge allow rapid
infusion of blood products and fluids, making them ideal for
emergencies or trauma situations.
9. What should the nurse do first if an IV pump alarm indicates
occlusion?
A. Turn off the pump permanently
B. Assess the tubing and IV site for blockage or kinks
C. Remove the IV immediately
D. Increase the infusion rate
Answer: B. Assess the tubing and IV site for blockage or kinks
Rationale: Occlusion alarms commonly occur due to kinks, clamped
tubing, or catheter obstruction. The nurse should assess the system
before taking further action.
10. Which complication is characterized by redness, warmth,
and tenderness along a vein?
A. Air embolism
B. Extravasation
C. Phlebitis
D. Fluid overload
Answer: C. Phlebitis
