Myocardium is rigid and noncompliant, impeding ventricular filling and raising pressures during diastole is which form of cardiomyopathy?

A. Jugular vein distention: Pulmonary hypertension increases right ventricular afterload, leading to right heart failure. As the right ventricle struggles to pump against elevated pulmonary pressures, blood backs up into the systemic circulation, causing jugular vein distention (JVD).

B. Peripheral edema: Right-sided heart failure due to pulmonary hypertension leads to venous congestion and fluid retention, resulting in peripheral edema. Swelling is commonly observed in the lower extremities due to increased venous hydrostatic pressure.

C. Ronchi bilaterally: Rhonchi are low-pitched breath sounds typically associated with airway obstruction due to secretions, commonly seen in conditions like chronic bronchitis or pneumonia. Pulmonary hypertension primarily affects the pulmonary vasculature rather than the airways, making rhonchi an unlikely manifestation.

D. Dyspnea on exertion: Pulmonary hypertension increases pressure in the pulmonary arteries, reducing oxygen exchange and causing exertional dyspnea. This symptom is often one of the earliest clinical manifestations as increased pulmonary vascular resistance impairs oxygen delivery.

E. Systemic blood pressure greater than 130/90 mm Hg: Pulmonary hypertension specifically affects the pulmonary circulation, not systemic arterial pressure. While pulmonary hypertension can eventually contribute to left heart dysfunction, it does not directly cause systemic hypertension.

A. Fever: Fever is a common sign of pericarditis, often indicating inflammation or infection in the pericardial sac. This symptom is typical in patients with this condition.

B. Mild chest pain: Mild chest pain is a typical symptom of pericarditis. Patients often experience sharp, pleuritic chest pain that may worsen with inspiration or coughing.

C. No evidence of fatigue: Fatigue can be a common symptom in patients with pericarditis due to the body's response to inflammation. Therefore, the absence of fatigue is not typical, making this an appropriate choice.

D. Myalgias: Myalgias or muscle aches can occur in pericarditis as part of the systemic inflammatory response. This symptom is not unusual in patients with this condition.

E. Pericardial friction rub: A pericardial friction rub is a characteristic finding in pericarditis, heard during auscultation. It results from the movement of inflamed pericardial layers against each other.

F. Radiating substernal pain felt in the left shoulder: This type of radiating pain is more characteristic of myocardial ischemia or angina rather than pericarditis. While pericarditis can cause chest pain, it does not typically radiate in the same manner as that seen in cardiac conditions, making this an appropriate choice.
