The nurse is assessing a client with right-sided heart failure. Which of the following findings should the nurse expect? Select all that apply.

A. Distended jugular veins: Right-sided failure increases pressure in the right atrium and vena cava, leading to visible engorgement of the internal jugular veins. This finding reflects the retrograde backup of blood into the systemic venous system. It is a primary clinical indicator of elevated central venous pressure. B. Weight gain: Rapid increase in body mass in heart failure patients is almost exclusively due to the retention of sodium and water. As the kidneys perceive low perfusion, the renin-angiotensin-aldosterone system triggers fluid volume expansion. This leads to the systemic accumulation of fluid characteristic of right-sided dysfunction. C. Orthopnea: This symptom involves difficulty breathing while lying flat and is a classic sign of left-sided heart failure and pulmonary congestion. It occurs when fluid from the lower extremities redistributes to the lungs in a recumbent position. Right-sided failure alone does not typically cause this pulmonary-specific symptom. D. Peripheral edema: Increased systemic venous pressure causes fluid to leak from the capillaries into the interstitial spaces of the lower extremities. This presents as swelling in the feet, ankles, and pretibial areas, often worsening as the day progresses. It is a hallmark sign of right-heart pump failure. E. Crackles the lungs: Adventitious lung sounds like crackles indicate fluid in the alveoli, which is a manifestation of pulmonary edema. Pulmonary edema is caused by the failure of the left ventricle to move blood into the systemic circulation. It is not a direct finding of isolated right-sided heart failure.
