A healthcare professional is educating a patient about asthma. The professional states that good control is necessary due to which pathophysiologic process?

Norepinephrine causes bronchial smooth muscle contraction and mucus secretion but it also causes high blood pressure

Uncontrolled inflammation leads to increased bronchial hyperresponsiveness and eventual scarring

Immunoglobulin G causes smooth muscle contraction which will eventually weaken the respiratory muscles

The release of epinephrine leads to development of cardiac dysrhythmias.

Answer and Explanation

The Correct Answer is B

A. Norepinephrine causes bronchial smooth muscle contraction and mucus secretion but it also causes high blood pressure: This statement is misleading in the context of asthma. Norepinephrine primarily acts on alpha and beta receptors, influencing blood pressure and bronchodilation but is not the main mediator in asthma pathophysiology. The focus should be on inflammation and airway responsiveness.

B. Uncontrolled inflammation leads to increased bronchial hyperresponsiveness and eventual scarring: This statement accurately describes the pathophysiologic process in asthma. Persistent inflammation in asthma can cause increased bronchial hyperresponsiveness, leading to airway narrowing and potential long-term remodeling and scarring of the airways if not controlled. Effective management is essential to prevent these adverse outcomes.

C. Immunoglobulin G causes smooth muscle contraction which will eventually weaken the respiratory muscles: Immunoglobulin E (IgE) is primarily involved in allergic reactions and asthma, and it does not directly cause smooth muscle contraction that weakens respiratory muscles.

D. The release of epinephrine leads to development of cardiac dysrhythmias: While epinephrine can have cardiovascular effects, including increased heart rate and potential for dysrhythmias, this is not directly relevant to the pathophysiology of asthma. The focus in asthma management is on controlling airway inflammation and bronchoconstriction rather than on cardiac issues.

Correct Answer is ["C","D","E"]

Explanation

A. Expecting copious amounts of frothy, pink sputum: This symptom is typically associated with left-sided heart failure or pulmonary edema, where fluid accumulates in the lungs, leading to the production of frothy, pink sputum. It is not a classic manifestation of right-sided heart failure.

B. Fine crackles throughout both lung fields: Fine crackles are more indicative of left-sided heart failure due to fluid accumulation in the lungs (pulmonary congestion). In right-sided heart failure, the primary issues relate more to systemic congestion rather than pulmonary congestion.

C. +pitting edema in lower extremities: Right-sided heart failure often leads to fluid retention and peripheral edema due to increased venous pressure. Pitting edema in the lower extremities is a common clinical manifestation in patients with cor pulmonale and right-sided heart failure.

D. Altered level of consciousness: This can occur due to decreased cardiac output and resulting reduced cerebral perfusion. In right-sided heart failure, especially in advanced stages, fluid overload can lead to increased intracranial pressure, contributing to altered mental status.

E. Jugular vein distention: Jugular vein distention is a classic sign of right-sided heart failure. Increased pressure in the right atrium due to fluid overload results in distended neck veins, indicating elevated venous pressure.

A. Shortness of breath and need for oxygen supplementation B. Tachycardia and hypotension C. Decreased alertness and slurred speech D. Diminished pulses and pain with walking or exercise

Correct Answer is D

Explanation

A. Shortness of breath and need for oxygen supplementation: These symptoms are more indicative of respiratory or cardiac conditions rather than Peripheral Artery Disease (PAD). While patients with PAD may experience discomfort during exertion, shortness of breath is not a primary symptom associated with PAD.

B. Tachycardia and hypotension: Tachycardia and hypotension are generally signs of acute distress, shock, or severe cardiovascular issues. These symptoms do not specifically indicate PAD, which is characterized by issues related to blood flow in the peripheral arteries.

C. Decreased alertness and slurred speech: These symptoms suggest possible neurological issues, such as a stroke or transient ischemic attack, rather than PAD. PAD primarily affects blood flow to the extremities and does not typically present with neurological symptoms.

D. Diminished pulses and pain with walking or exercise: Diminished pulses in the legs and claudication, or pain with walking or exercise, are classic symptoms of Peripheral Artery Disease. These symptoms occur due to reduced blood flow to the muscles in the legs, particularly during physical activity, and are indicative of arterial blockages.
