A client with a history of myocardial infarction (MI) develops pulmonary edema. Which pathophysiological process is likely occurring in this client, leading to fluid accumulation in the lungs?

Increased myocardial contractility

Reduced afterload on the heart

Left ventricular remodeling

Enhanced pulmonary vasodilation

Answer and Explanation

The Correct Answer is C

A) Incorrect. Increased myocardial contractility would not typically lead to left ventricular remodeling but might improve cardiac function.

B) Incorrect. Reduced afterload on the heart may be beneficial, but it is not a primary factor in left ventricular remodeling.

C) Correct. Left ventricular remodeling, often occurring after a myocardial infarction, involves changes in the size and shape of the ventricle, which can impair cardiac function and lead to pulmonary edema.

D) Incorrect. Enhanced pulmonary vasodilation is not a primary cause of left ventricular remodeling or pulmonary edema.

Correct Answer is A

Explanation

A) Correct. Increased hydrostatic pressure in pulmonary capillaries, often due to left ventricular failure, leads to the filtration of fluid from the capillaries into the alveoli and interstitial spaces, causing pulmonary edema.

B) Incorrect. Decreased capillary permeability is not typically a primary factor in the development of pulmonary edema.

C) Incorrect. Enhanced lymphatic drainage from the lungs is not a primary mechanism responsible for the accumulation of fluid in pulmonary edema.

D) Incorrect. Elevated colloid osmotic pressure in pulmonary vessels would oppose fluid accumulation in the alveoli and is not a primary cause of pulmonary edema.

A. A bacterial lung infection B. An inflammation of the pleura C. Accumulation of excess fluid in the lungs D. A blockage in the coronary arteries

Correct Answer is C

Explanation

A) Incorrect. Pulmonary edema is not a bacterial lung infection.

B) Incorrect. Pleuritis (inflammation of the pleura) is a different condition unrelated to pulmonary edema.

C) Correct. Pulmonary edema is characterized by the accumulation of excess fluid in the lungs, often in the alveoli and interstitial spaces.

D) Incorrect. A blockage in the coronary arteries is related to myocardial infarction (heart attack) and is not the primary characteristic of pulmonary edema.
