A client scheduled for a carotid endarterectomy requires insertion of an intra-arterial blood pressure-monitoring device. The nurse plans to perform the Allen test. Which observation indicates patency of the ulnar artery?
- A. Blanching of the hand on compression and release of the ulnar artery
- B. Muscular twitching of the bicep muscle with use of a tourniquet at the wrist
- C. Hand turning pink after the nurse releases the pressure on the ulnar artery
- D. Flexion of the wrist when tapping the ulnar artery with a reflex hammer
Correct Answer: C
Rationale: The Allen test assesses collateral circulation. The hand turning pink after releasing ulnar artery pressure indicates patency, ensuring adequate blood flow if the radial artery is cannulated.
