Correct Answer is D
Explanation
A. Smoking: Although smoking is a risk factor for cardiovascular diseases and can contribute to thrombosis, it is not the most immediate factor in the context of post-surgical immobility.
B. Hypertension: While hypertension is a significant cardiovascular risk factor, it is less directly related to deep vein thrombosis compared to immobility.
C. Obesity: Obesity can increase the risk of DVT, but immobility, especially after surgery, is a more direct and immediate contributing factor.
D. Immobility: Immobility is a critical factor in the development of deep vein thrombosis, particularly in postoperative clients who may be bedridden or have limited mobility.
Correct Answer is B
Explanation
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.
D. Diaphragm and bell on same side: Allows for a complete assessment of heart sounds, though it may be less versatile than separate components on each side.
