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?
Cool extremities
Positive Phalen's sign
Positive Trousseau's sign
Decreased radial pulse
The Correct Answer is B
B. Phalen's sign is a test for carpal tunnel syndrome. It is positive when the client experiences numbness, tingling, or pain in the median nerve distribution (especially the thumb, index finger, middle finger, and half of the ring finger) within 1 minute of wrist flexion.
A. Cool extremities are not typically associated with carpal tunnel syndrome. They may indicate issues related to circulation rather than compression of the median nerve.
C. Trousseau's sign is a test for latent tetany, which is associated with hypocalcemia. It involves inflating a blood pressure cuff on the upper arm and observing for carpal spasm. It is not a manifestation of carpal tunnel syndrome.
D. A decreased radial pulse may indicate vascular issues or compression of the radial artery, not carpal tunnel syndrome.

Correct Answer is C
Explanation
C. A neurovascular assessment involves evaluating the circulation, sensation, and movement of the limb distal to the cast to ensure there are no signs of neurovascular compromise, such as decreased pulses, numbness, tingling, or weakness. Prompt identification of any neurovascular impairment is essential for preventing complications such as compartment syndrome.
A. Explaining discharge instructions is important for ensuring the client and their parents understand how to care for the cast at home. However, it is not the priority action.
B. Applying an ice pack to the casted leg can help reduce swelling and provide pain relief, but it is not the priority action immediately after the cast application.
D. Providing reassurance is important for alleviating anxiety and promoting a positive experience for the client and their parents. However, it is not the priority action.
Correct Answer is D
Explanation
D. Tachypnea is a classic early manifestation of fat embolism syndrome. Fat emboli can travel to the lungs and obstruct blood flow, leading to respiratory distress and hypoxemia. Tachypnea is the body's response to hypoxemia, as it attempts to increase oxygen intake by breathing more rapidly.
A. Swelling of the calf can occur with conditions such as deep vein thrombosis (DVT), but it is not typically an early manifestation of fat embolism syndrome.
B. tachycardia is more commonly seen due to the body's response to decreased oxygen levels and increased demand on the cardiovascular system.
C. Hypertension is not typically associated with fat embolism syndrome. Instead, hypotension can occur due to decreased cardiac output and systemic vasodilation in severe cases of fat embolism syndrome.
