A. Diaphragm on one side, bell on the opposite side: Suitable for a full cardiac examination, as it can assess both high and low-frequency sounds.

B. Diaphragm Only: Less suitable for a full cardiac examination because it may not effectively capture low-frequency sounds such as certain heart murmurs.

C. Bell on one side, Diaphragm on the opposite side: Effective for a full cardiac examination, as it can assess both high and low-frequency sounds.

Correct Answer is D

Explanation

A. Aortic murmurs: These are best assessed with the client in an upright or slightly leaning forward position, not specifically the left lateral position.

B. Atrial repolarization: This is not directly assessed by body position; it is part of the ECG assessment.

C. The first heart sound: The first heart sound (S1) is heard throughout the auscultation process and is not specifically enhanced by a left lateral position.

D. Mitral stenosis: The left lateral position allows better auscultation of the mitral area, where mitral stenosis murmurs are best heard.

A. Venous insufficiency ulcers B. Arterial insufficiency ulcers C. Neuropathic ulcers D. Deep vein thrombosis

Correct Answer is B

Explanation

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.
