Following a myocardial infarction (MI) of the left ventricle, a patient develops left heart failure (LHF). Findings commonly associated with LHF include

low preload.

pleural effusion.

peripheral edema.

pulmonary edema.

Answer and Explanation

The Correct Answer is D

A. Preload is typically increased in LHF, as blood backs up in the left side of the heart.

B. Although pleural effusion can occur as a secondary complication in some cases of heart failure, it is not as directly indicative of LHF as pulmonary edema.

C. Peripheral edema is more characteristic of right heart failure, where blood backs up in the systemic circulation.

D. Pulmonary edema is a hallmark finding in left heart failure as the left ventricle fails to pump effectively, causing fluid to accumulate in the lungs due to back pressure from the left atrium into the pulmonary veins.

Correct Answer is A

Explanation

A. Endometriosis involves the growth of endometrial tissue outside the uterus, causing inflammation, scarring, and adhesions that may obstruct reproductive pathways, leading to infertility.

B. Endometriosis typically does not cause urethral strictures; adhesions affect the reproductive tract, not the urinary system.

C. While retrograde menstruation is a theory for endometriosis development, it does not directly lead to a neoplastic (cancerous) condition of the ovaries.

D. Endometriosis is not caused by an untreated bacterial infection; rather, it is a condition of abnormal endometrial tissue growth.

A. The uninjured lung will hyperinflate because of an increased respiratory rate. B. Affected lung collapses as more air is exhaled through the traumatic injury. C. Trapped air causes collapse of the lung and can reduce the cardiac output. D. More CO2 is retained because weakened alveoli blebs rupture.

Correct Answer is C

Explanation

A. While an increased respiratory rate may occur, it does not directly lead to hyperinflation of the uninjured lung due to tension pneumothorax.

B. In a tension pneumothorax, air enters the pleural space and does not exhale effectively; it is not about exhalation.

C. Trapped air in the pleural cavity increases pressure, collapsing the lung and pushing mediastinal structures (like the heart) to the opposite side, thereby reducing venous return and cardiac output.

D. Retained CO2 is not a direct cause of tension pneumothorax; the main issue is the pressure from trapped air affecting lung function and hemodynamics.
