A nurse in a provider’s office is assessing a client who has wrist pain. Which of the following findings is a manifestation of carpal tunnel syndrome?

Choice A reason: A positive Phalen’s sign, pain or numbness when flexing wrists for 60 seconds, indicates median nerve compression in carpal tunnel syndrome. This is a diagnostic hallmark, making it the correct manifestation for the condition. Choice B reason: Cool extremities suggest vascular issues, not carpal tunnel syndrome, which involves nerve compression. Temperature changes are not a primary feature, making this incorrect for the client’s wrist pain. Choice C reason: Decreased radial pulse is unrelated to carpal tunnel syndrome, which affects the median nerve, not arterial flow. Pulse changes might indicate other conditions, making this incorrect for the diagnosis. Choice D reason: Trousseau’s sign, arm muscle spasms with blood pressure cuff inflation, indicates hypocalcemia, not carpal tunnel syndrome. It’s unrelated to wrist nerve compression, making this incorrect for the manifestation.
