A nurse is assessing a client at a dermatology clinic. Which of the following findings places the client at risk for developing malignant melanoma?

Choice A reason: Positive Trousseau's sign
Trousseau's sign is indicative of hypocalcemia, not CTS. It is elicited by inflating a blood pressure cuff on the upper arm to above systolic pressure for 3 minutes. A positive sign is characterized by carpal spasm, which is not related to CTS.

Choice B reason: Cool extremities
Cool extremities can be a result of various conditions, including peripheral vascular disease or hypothyroidism. They are not a specific indicator of CTS, which primarily affects nerve function rather than blood circulation or temperature regulation.

Choice C reason: Decreased radial pulse
A decreased radial pulse is not typically associated with CTS. It may indicate a cardiovascular issue or a blockage in the radial artery, which would require further investigation unrelated to CTS.

Choice D reason: Positive Phalen's sign
Phalen's sign is a diagnostic test for CTS. The test is performed by having the patient flex their wrist maximally and hold the position for about 60 seconds. A positive Phalen's sign, which includes numbness and tingling in the thumb, index finger, middle finger, and the radial half of the ring finger, is indicative of CTS. This occurs due to increased pressure on the median nerve when the wrist is in flexion.

Choice A reason:
Ecchymosis, or bruising, of the surrounding skin is a common finding associated with fractures due to the trauma to blood vessels in the area. While it can indicate bleeding or injury, ecchymosis itself does not specifically indicate impaired venous return.

Choice B reason:
Acute pain is a typical symptom following a fracture and results from the injury to the bone and surrounding tissues. Pain is an expected finding and does not directly suggest an issue with venous return.

Choice C reason:
A bounding distal pulse may actually suggest increased arterial flow or could be a sign of other conditions such as high blood pressure or fever. It does not indicate impaired venous return, which is typically characterized by a lack of pulse or a very weak pulse.

Choice D reason:
Increasing edema, or swelling, in the affected arm is a sign of impaired venous return. When veins are unable to effectively return blood to the heart, fluid can accumulate in the tissues, leading to edema. In the context of a fracture, this could be due to compression or damage to the veins, which can impede blood flow and result in swelling.
