Myocardium is rigid and noncompliant, impeding ventricular filling and raising pressures during diastole is which form of cardiomyopathy?
Septal
Restrictive
Infiltrative
Hypertrophic
The Correct Answer is B
A. Septal: Septal cardiomyopathy typically refers to abnormalities in the interventricular septum and does not specifically address the rigidity and noncompliance of the myocardium that affects diastolic filling.
B. Restrictive: Restrictive cardiomyopathy is characterized by a rigid and noncompliant myocardium that impedes ventricular filling during diastole. This results in elevated pressures in the ventricles and may lead to heart failure symptoms due to poor filling capacity.
C. Infiltrative: Infiltrative cardiomyopathy involves the deposition of abnormal substances (such as amyloid or sarcoid) within the myocardial tissue, which can lead to stiffness. While this may contribute to restrictive physiology, "restrictive" is the more precise term for the condition described.
D. Hypertrophic: Hypertrophic cardiomyopathy is characterized by an abnormal thickening of the heart muscle, particularly the left ventricle. While this condition can affect diastolic filling, it is primarily due to muscle hypertrophy rather than rigidity and noncompliance of the myocardium.

Correct Answer is A
Explanation
A. Obstructive: Obstructive pulmonary disease is characterized by increased resistance in the airways, making it more difficult to expire air. Conditions such as asthma and chronic obstructive pulmonary disease (COPD) lead to airflow limitation, requiring greater force to expel air from the lungs.
B. Communicable: Communicable pulmonary diseases refer to infections that can be transmitted from person to person, such as tuberculosis or influenza. This classification does not directly relate to the mechanics of airflow and does not specifically require more force to expire air.
C. Acute: Acute pulmonary disease describes a sudden onset of symptoms, which can be caused by various conditions (e.g., pneumonia or pulmonary embolism). The term "acute" does not inherently indicate a need for increased expiratory force and can encompass both obstructive and restrictive patterns.
D. Restrictive: Restrictive pulmonary disease involves reduced lung volume and compliance, making it difficult to expand the lungs fully during inspiration. While patients may struggle to inhale adequately, they typically do not require increased force to expire air, as expiratory airflow is usually not obstructed in the same manner as in obstructive diseases.
Correct Answer is A
Explanation
A. We will have to drain the pus out of your pleural space: An empyema is characterized by the accumulation of pus in the pleural space, typically due to infection or inflammation. The primary treatment often involves draining the infected fluid to relieve symptoms and treat the underlying infection, making this statement accurate and appropriate for the patient.
B. These blebs in your lungs can rupture with exercise: This statement is not applicable to empyema. Blebs are associated with conditions like pulmonary bullae or emphysema, not empyema. Empyema specifically refers to pus in the pleural space, not blebs in the lungs.
C. You will be given a long course of antiviral medication: Antiviral medication is not typically indicated for empyema, as it is often caused by bacterial infections. Treatment usually involves antibiotics and drainage rather than antiviral therapy.
D. We will watch you for respiratory muscle fatigue: While monitoring for respiratory status is important in any patient with empyema, this statement does not specifically address the nature of empyema or its treatment. The focus should be on managing the infection and drainage of the pleural space.
