A client who works at a computer most of the working day comes to the clinic reporting pain in both hands that causes the client to wake during the night. Which action should the nurse implement to assess for carpal tunnel syndrome?

Choice A reason: Comparing the capillary refill in the hands is a useful assessment for evaluating peripheral circulation, but it is not specific to diagnosing carpal tunnel syndrome. Carpal tunnel syndrome involves compression of the median nerve, and capillary refill does not provide information about nerve compression.Choice B reason: Determining the client's sleeping position may provide insight into factors that exacerbate symptoms, but it does not directly assess for carpal tunnel syndrome. While certain positions might worsen the condition, this information alone is not diagnostic.Choice C reason: Applying firm pressure over the ulnar artery is not relevant to assessing carpal tunnel syndrome. The ulnar artery supplies blood to the hand, but carpal tunnel syndrome involves the median nerve, not the ulnar artery.Choice D reason: Tapping the client's wrists to locate the pain, known as Tinel's sign, is a specific test for carpal tunnel syndrome. Tinel's sign is positive when tapping over the median nerve at the wrist elicits tingling or pain in the fingers, indicating nerve compression.
