Correct Answer is B

Explanation

A. S3 heart sound: An S3 heart sound is often associated with heart failure and volume overload, not specifically mitral stenosis.

B. Dyspnea on exertion: Dyspnea on exertion is a classic symptom of mitral stenosis. The narrowing of the mitral valve restricts blood flow from the left atrium to the left ventricle, causing pulmonary congestion and shortness of breath, especially during physical activity.

C. Cyanosis: While cyanosis can occur in advanced stages of heart disease, it is not a primary symptom of mitral stenosis. It indicates severe oxygenation issues, which are usually late findings.

D. S4 heart sound: An S4 heart sound is typically associated with left ventricular hypertrophy, which can occur in advanced cases of mitral stenosis. However, it's not a specific early manifestation of the condition.

A. Cool skin B. Numbness C. Edema D. Pallor

Correct Answer is C

Explanation

A. Cool skin: Cool skin is not typically associated with thrombophlebitis. It is more common with arterial issues rather than venous problems.

B. Numbness: Numbness is generally a sign of nerve involvement or arterial occlusion, not a classic finding of thrombophlebitis, which primarily affects veins.

C. Edema: Edema is a common finding with thrombophlebitis due to venous inflammation and obstruction of blood flow, which leads to fluid accumulation in the affected limb.

D. Pallor: Pallor is more commonly associated with arterial insufficiency rather than venous issues like thrombophlebitis. Thrombophlebitis often presents with redness and warmth instead of pallor.
