INTRODUCTION *
, This comprehensive assessment is designed to evaluate the proficiency and clinical readiness of
healthcare professionals seeking IV Therapy Certification. The exam covers essential foundational
theories and advanced clinical applications necessary for safe infusion practice. Candidates are assessed
on their ability to integrate knowledge of fluid dynamics, site selection, and pharmacological safety with
critical decision-making skills. The structure includes both direct knowledge-based questions and complex
clinical scenarios to mirror real-world practice. Emphasis is placed on patient safety, legal compliance, and
the application of evidence-based standards to ensure optimal patient outcomes during intravenous
therapy and the management of potential complications. *
SECTION ONE
1. Which of the following is the most appropriate site for initiating a peripheral IV in an adult patient to
minimize the risk of mechanical phlebitis?
A. Ventral surface of the wrist
B. Basilic vein on the forearm
C. Large veins in the foot
D. Antecubital fossa
🟢 Correct answer: B
🔴 RATIONALE: The forearm provides better stabilization for the catheter compared to joint areas like the
antecubital fossa or wrist, reducing mechanical irritation to the vein wall.
2. A patient is prescribed a hypertonic solution. What is the primary physiological effect of this solution on the
cellular level?
A. Causes cells to swell as fluid moves into the intracellular space
B. Has no effect on the movement of water across the cell membrane
C. Pulls fluid from the intracellular space into the intravascular space
D. Decreases the osmotic pressure within the vascular system
,🟢 Correct answer: C
🔴 RATIONALE: Hypertonic solutions have a higher osmolarity than plasma, creating an osmotic gradient that
draws water out of the cells and into the bloodstream.
3. During the assessment of a peripheral IV site, the nurse notes coolness, swelling, and blanched skin.
These findings are most indicative of:
A. Infiltration
B. Thrombophlebitis
C. Localized infection
D. Venous spasm
🟢 Correct answer: A
🔴 RATIONALE: Infiltration occurs when non-vesicant fluid enters the subcutaneous tissue, typically presenting
with coolness, edema, and pallor at the insertion site.
4. According to the Infusion Nurses Society (INS) standards, how often should a transparent semipermeable
membrane dressing on a peripheral IV site be changed?
A. Every 24 hours
B. Every 48 to 72 hours
C. Every 5 to 7 days
D. Only when the catheter is rotated or if the dressing is soiled
🟢 Correct answer: D
🔴 RATIONALE: Current standards recommend changing transparent dressings on peripheral sites when the
catheter is replaced or if the dressing becomes damp, loose, or visibly soiled.
5. Which gauge size is typically recommended for the administration of blood products in an adult to prevent
hemolysis and ensure adequate flow?
, A. 24-gauge
B. 22-gauge
C. 18-gauge
D. 26-gauge
🟢 Correct answer: C
🔴 RATIONALE: An 18-gauge catheter is preferred for blood transfusions to allow for rapid infusion and to
prevent damage to red blood cells as they pass through the lumen.
6. A nurse is preparing to administer a vesicant medication. Which action is most critical for patient safety?
A. Selecting the smallest vein possible
B. Verifying brisk blood return before and during administration
C. Using a pump set at the highest possible rate
D. Placing the IV in the hand for better visibility
🟢 Correct answer: B
🔴 RATIONALE: Confirming blood return ensures the catheter is properly positioned within the vein, minimizing
the risk of extravasation of vesicant drugs which can cause tissue necrosis.
7. What is the first intervention a nurse should perform if a patient develops a suspected air embolism?
A. Place the patient in Trendelenburg position on their left side
B. Increase the IV flow rate to flush the air through
C. Elevate the head of the bed to 90 degrees
D. Administer a bolus of normal saline
🟢 Correct answer: A
🔴 RATIONALE: The left lateral Trendelenburg position (Durant's maneuver) helps trap the air bubble in the
apex of the right ventricle, preventing it from entering the pulmonary artery.
