The nurse is performing an assessment on a client with a history of cardiovascular disease, diabetes, hypertension, and hypothyroidism. The client is experiencing exhaustion with simple activities of daily living and short ambulation, and states a 5-pound weight gain over 4 days. Assessment reveals 4+ edema to lower extremities and jugular distention. The nurse will report findings to the health care provider and anticipates which medical condition?

A. Myocardial infarction: While this patient has significant cardiovascular risk factors, the clinical presentation does not describe acute substernal chest pain or EKG changes. The presence of 4+ peripheral edema and jugular venous distention points toward a chronic congestive process rather than acute coronary occlusion. Weight gain and exhaustion are symptoms of volume overload. B. Left-sided heart failure: Left-sided failure typically presents with pulmonary congestion, characterized by crackles, orthopnea, and paroxysmal nocturnal dyspnea. While it often precedes right-sided failure, the specific findings of jugular distention and lower extremity edema are hallmarks of systemic venous congestion. This choice does not align with the predominant systemic symptoms described. C. Acute pericarditis: Pericarditis usually presents with sharp, pleuritic chest pain that improves when leaning forward, often accompanied by a pericardial friction rub. It does not typically cause massive peripheral edema or rapid weight gain unless it progresses to cardiac tamponade. The clinical signs in the stem indicate high systemic venous pressure. D. Right-sided heart failure: This condition results in the inability of the right ventricle to pump blood into the pulmonary circulation, causing systemic backup. Jugular venous distention, 4+ pitting edema, and rapid weight gain are classic signs of systemic venous hypertension. The exhaustion stems from decreased cardiac output during physical exertion.
