A patient is diagnosed with infective endocarditis prior to valve replacement surgery. Which symptom should the nurse anticipate during the preoperative assessment?

Choice A rationale Hypertension and anxiety are non-specific findings that do not characterize the classic presentation of infective endocarditis. While a patient may feel anxious about an upcoming surgery, endocarditis itself often leads to hemodynamic instability or even hypotension if valvular regurgitation becomes severe. Hypertension is not a diagnostic hallmark of this condition, which is primarily an inflammatory and infectious process affecting the heart's inner lining and the fragile structures of the cardiac valves. Choice B rationale Dizziness and bradycardia are not the primary symptoms expected during the preoperative assessment for endocarditis. While dizziness can occur if there is significant heart failure or embolization to the brain, bradycardia is rare unless the infection has formed a perivalvular abscess that interferes with the heart's conduction system, such as the atrioventricular node. These symptoms are less common than the systemic signs of infection and the peripheral manifestations of the disease process itself. Choice C rationale Fever, fatigue, and petechiae are classic findings in infective endocarditis. Fever is present in the vast majority of cases due to the ongoing bacteremia. Fatigue results from the systemic inflammatory response and potential anemia of chronic disease. Petechiae are small, red-purple spots on the skin or mucous membranes caused by micro-emboli or immune complex deposition in the capillaries. These symptoms reflect the infectious nature of the disease and its systemic vascular impacts prior to surgery. Choice D rationale Peripheral edema and cyanosis are more indicative of advanced heart failure or severe pulmonary disease rather than the specific early presentation of infective endocarditis. While right-sided heart failure resulting from tricuspid valve endocarditis could cause edema, it is less common as an initial preoperative finding compared to the triad of fever and embolic signs. Cyanosis indicates significant deoxygenation, which is not a primary feature of endocarditis unless a major pulmonary embolism or profound shunting occurs.
