A patient has pleural effusion with empyema. The following are clinical manifestations except:
Bradycardia
Pleural pain
Cough
Fever
The Correct Answer is A
A. Bradycardia: Bradycardia, which is a slower than normal heart rate, is not a typical clinical manifestation of pleural effusion with empyema. In fact, fever and infection usually lead to tachycardia (an increased heart rate) as the body attempts to respond to infection.
B. Pleural pain: Pleural pain is a common symptom associated with pleural effusion and empyema, resulting from irritation of the pleura due to inflammation or infection.
C. Cough: A cough can occur with pleural effusion and empyema, often as a response to irritation or pressure in the thoracic cavity. It may also be associated with underlying lung conditions contributing to the effusion.
D. Fever: Fever is a typical clinical manifestation of empyema, indicating an infectious process. The presence of infection in the pleural space often results in systemic signs of infection, such as fever.

Correct Answer is C
Explanation
A. Atherosclerotic lesion: An atherosclerotic lesion can lead to reduced blood flow to the myocardium, but it is not the direct trigger for angina pectoris. Rather, it is a contributing factor to the development of conditions that cause angina.
B. Myocardial necrosis: Myocardial necrosis refers to irreversible cell damage due to prolonged ischemia, such as in a myocardial infarction. This is not a trigger for angina pectoris but rather a consequence of severe and prolonged ischemia.
C. Myocardial ischemia: Myocardial ischemia is the primary trigger for angina pectoris. It occurs when there is an imbalance between the oxygen supply and demand in the heart muscle, typically due to narrowed coronary arteries. This insufficient blood flow results in chest pain or discomfort characteristic of angina.
D. Hyperlipidemia: Hyperlipidemia is a risk factor for atherosclerosis and subsequent coronary artery disease but does not directly trigger angina pectoris. It contributes to the underlying processes that lead to myocardial ischemia.
Correct Answer is A
Explanation
A. Myocardial ischemia: Myocardial ischemia contributes to ventricular remodeling by causing damage to the heart muscle, leading to changes in the size, shape, and function of the ventricles. The process involves cellular and molecular alterations in response to ischemic injury, ultimately resulting in adverse remodeling that can exacerbate heart failure.
B. Right ventricular failure: Right ventricular failure may occur as a consequence of other cardiac conditions but is not a direct contributor to ventricular remodeling. Instead, it is often a result of left-sided heart failure or pulmonary hypertension, making it secondary to the primary pathologic changes.
C. Left ventricular hypertrophy: Left ventricular hypertrophy can occur as a response to chronic pressure overload (such as hypertension) but is a result of ventricular remodeling rather than a direct contributor to the remodeling process itself. It may indicate underlying issues rather than cause them.
D. Contractile dysfunction: Contractile dysfunction reflects impaired heart muscle contraction but does not directly cause ventricular remodeling. While it can be a consequence of remodeling due to conditions like ischemia or heart failure, it does not initiate the remodeling process itself.
