Which clinical finding is most consistent with right-sided heart failure secondary to chronic hypoxia?

• A. High-pitched rales over the bases.
• B. Elevated jugular venous pressure and peripheral edema.
• C. Decreased intolerance to exercise only.
• D. Hyperactive bowel sounds.

Answer: (B)

Right-sided heart failure causes a backup of blood into the systemic venous circulation, leading to congestion outside the heart. When chronic hypoxia leads to pulmonary hypertension, the right ventricle has to work harder to pump blood through the lungs, eventually dilating and failing. The hallmark signs of this systemic venous congestion are elevated jugular venous pressure and peripheral edema. Raised JVP reflects increased pressure in the right atrium and thoracic veins, while edema results from fluid leaking into tissues due to higher hydrostatic pressure in the systemic capillaries.

Other options don’t fit as well. High-pitched rales over the bases point more to left-sided heart involvement or pulmonary edema, not the typical pattern of isolated right-sided failure. Decreased exercise tolerance can occur with many conditions and isn’t specific. Hyperactive bowel sounds aren’t associated with right-sided heart failure.
