The nurse is planning care for a client recovering from orthopedic surgery. Interventions should be included to address which contributing factor to deep vein thrombosis development?

Rationale:
A. Second or third intercostal space at the left sternal border: Erb's point is located here, and it's a key area for listening to heart sounds, particularly the aortic and pulmonic valves.

B. The second intercostal space at the right sternal border: This area is typically used to auscultate the aortic valve.

C. Fifth intercostal space near the left midclavicular line: This area is used to auscultate the mitral valve, not Erb's point.

D. Third intercostal space at the left sternal border: This is the location for listening to the pulmonic valve, not Erb's point.

A. Venous insufficiency ulcers: Typically present with dark discoloration and edema, but not specifically with changes in color with elevation and dependency.

B. Arterial insufficiency ulcers: Pale feet when elevated and dark red when dependent are classic signs of arterial insufficiency. These changes in color are due to poor blood flow.

C. Neuropathic ulcers: Usually associated with diabetes and often occur on pressure points, not typically related to color changes with elevation.

D. Deep vein thrombosis: While DVT can cause swelling and pain, it does not usually present with color changes that are dependent on the position of the foot.
