A patient with Syndrome of Inappropriate Antidiuretic Hormone (SIADH) may present with which of the following symptoms?
Hypotension
Dry mucous membranes
Increased thirst
Confusion or altered mental status
The Correct Answer is D
A. Hypotension: Patients with SIADH typically have fluid retention, which can lead to hypertension, not hypotension.
B. Dry mucous membranes: In SIADH, fluid retention is common, so mucous membranes are usually moist, not dry.
C. Increased thirst: While thirst can occur in various conditions, it is not a primary symptom of SIADH.
D. Confusion or altered mental status: Confusion or altered mental status may occur in SIADH due to hyponatremia from excessive water retention.

Correct Answer is B
Explanation
A. High fluid intake: High fluid intake can help maintain blood flow and reduce the risk of venous stasis.
B. Immobility during and after surgery: Immobility contributes to venous stasis and is a primary risk factor for DVT, especially after prolonged surgery.
C. Low body temperature: Low body temperature does not directly cause venous stasis or increase the risk of DVT.
D. Increased physical activity: Increased physical activity promotes circulation and reduces the risk of DVT by preventing blood from pooling in the veins.
