SECTION 6: FUNDAMENTALS OF IV THERAPY –
CNJNE IV CERTIFICATION EXAMINATION
COMPLETE QUESTIONS AND DETAILED SOLUTIONS
LATEST UPDATE THIS YEAR JUST RELEASED
Question 1
A nurse preparing to initiate intravenous therapy should first verify which
important factor before gathering equipment and approaching the patient?
A. The patient's preferred meal schedule
B. The healthcare provider's IV therapy prescription and patient identity
C. The patient's room temperature
D. The availability of family members
Answer: B
Rationale: Verifying the provider's order and correctly identifying the patient are
essential safety steps before initiating IV therapy.
Question 2
Which statement best explains the primary purpose of intravenous therapy when
caring for hospitalized patients requiring immediate treatment?
A. It permanently replaces oral medications.
B. It provides direct access to the bloodstream for fluids, medications, nutrients,
or blood products.
C. It eliminates the need for patient monitoring.
D. It prevents all infections.
,Answer: B
Rationale: IV therapy delivers substances directly into circulation, allowing rapid
and controlled therapeutic effects.
Question 3
Which vein characteristic should generally receive the highest priority when
selecting a peripheral intravenous insertion site for an adult patient?
A. A vein located directly over a joint
B. A small fragile vein near the wrist
C. A straight, palpable, resilient vein with adequate size
D. A previously infiltrated vein
Answer: C
Rationale: Straight, resilient veins reduce insertion difficulty and improve catheter
longevity while minimizing complications.
Question 4
Why is strict hand hygiene considered one of the most effective interventions
before performing peripheral intravenous catheter insertion?
A. It improves venous dilation.
B. It reduces the transmission of microorganisms responsible for catheter-related
infections.
C. It decreases infusion pump alarms.
D. It prevents medication incompatibility.
Answer: B
,Rationale: Proper hand hygiene is the single most effective measure for
preventing healthcare-associated infections.
Question 5
Which peripheral intravenous catheter gauge is generally preferred when rapid
administration of large fluid volumes may become necessary?
A. 24 gauge
B. 22 gauge
C. 20 or 18 gauge
D. 26 gauge
Answer: C
Rationale: Larger-bore catheters permit higher flow rates, making them
appropriate for rapid fluid resuscitation.
Question 6
Before inserting a peripheral intravenous catheter, why should the nurse inspect
both upper extremities whenever possible?
A. To identify the most appropriate vein while avoiding compromised sites
B. To determine blood glucose levels
C. To assess respiratory function
D. To reduce medication costs
Answer: A
Rationale: Comparing both arms helps identify healthier veins and avoid
unsuitable insertion sites.
, Question 7
Which action best promotes successful venous distention before peripheral
intravenous catheter insertion?
A. Applying a tourniquet appropriately above the intended insertion site
B. Elevating the extremity above heart level
C. Applying ice to the insertion site
D. Massaging directly over the vein after antiseptic preparation
Answer: A
Rationale: A properly applied tourniquet temporarily impedes venous return,
enlarging superficial veins.
Question 8
Which antiseptic solution is commonly recommended for skin preparation before
peripheral intravenous catheter insertion unless contraindicated?
A. Sterile water
B. Chlorhexidine-based solution
C. Saline only
D. Mineral oil
Answer: B
Rationale: Chlorhexidine provides broad-spectrum antimicrobial activity and is
recommended by many infection prevention guidelines.
Question 9
During catheter insertion, what insertion angle is commonly recommended when
initially entering the skin and vein?
