While percussing the borders of the heart, the nurse picks up an area of dullness beginning at the 5th left intercostal space and moving upward to the 2nd left intercostal space at the sternal border. What do these findings indicate?
Benign variation.
Cardiac atrophy.
Expected finding.
Cardiac enlargement.
The Correct Answer is D
A. Benign variation. This finding is not typically considered a benign variation and warrants further evaluation.
B. Cardiac atrophy. Cardiac atrophy would likely present differently and is not typically diagnosed via percussion findings alone.
C. Expected finding. This finding is within normal limits for the size and location of the heart's borders on percussion.
D. Cardiac enlargement. Cardiac enlargement might present with percussion dullness extending beyond normal limits, but the described findings do not indicate enlargement beyond expected borders.

Correct Answer is C
Explanation
A. Cool, pale skin below the knees. This suggests arterial insufficiency rather than venous insufficiency.
B. Deep, continuous pain in the calf muscles. This suggests deep vein thrombosis (DVT) rather than chronic venous insufficiency.
C. Decreased pain when legs are elevated. This is the best choice as elevation typically relieves symptoms of venous insufficiency by reducing venous pressure.
D. Painful symptoms alleviated by warmth. This is less specific to venous insufficiency and more indicative of muscle or joint issues.
Correct Answer is B
Explanation
A. Sternum. Auscultating directly over the sternum does not provide optimal lung sounds.
B. Lung apex. This is the best choice as auscultation should begin at the lung apex to systematically cover all lung fields.
C. Clavicle. Auscultating over the clavicle does not provide optimal lung sounds.
D. Aortic site. The aortic site is for heart sounds, not lung sounds.
