Correct Answer is ["B","C","D"]

Explanation

A. Obese extremities. Clients with Cushing's syndrome typically experience central (truncal) obesity with thin extremities due to fat redistribution and muscle wasting, not obese extremities.

B. Buffalo hump: A "buffalo hump" (fat pad on the back of the neck) is a common characteristic of Cushing's syndrome due to abnormal fat distribution.

C. Purple striations. Purple or reddish striae on the abdomen and other areas are commonly seen in Cushing's syndrome due to skin thinning and collagen breakdown.

D. Moon face. A round, full face (moon face) is a classic sign of Cushing's syndrome due to fat deposits in the face.

E. Tremors. Tremors are not typically associated with Cushing's syndrome and are more often associated with neurological or metabolic conditions.

A. Initiate intravenous fluid therapy B. Prepare the client for emergency surgery C. Administer high flow oxygen via a non-rebreather mask D. Apply sequential compression devices (SCDs)

Correct Answer is C

Explanation

A. Initiate intravenous fluid therapy. While fluid therapy is essential to support circulation and reduce the risk of shock, oxygenation takes priority in fat embolism management.

B. Prepare the client for emergency surgery. Surgery is not typically the first-line intervention for fat embolism; management focuses on supportive care, particularly respiratory support.

C. Administer high-flow oxygen via a non-rebreather mask. High-flow oxygen is the first priority to address hypoxia caused by fat embolism and should be administered immediately to maintain adequate oxygenation.

D. Apply sequential compression devices (SCDs). SCDs are used to prevent venous thromboembolism, but they do not help with the treatment of fat embolism.
