A patient had a ruptured aneurysm, which caused a CVA

A. It is the one for which capillary membranes become extra permeable during inflammation, allowing certain proteins to move to tissues. This describes the interstitial fluid, not the intracellular fluid (ICF). During inflammation, the capillary membranes allow proteins to move into the tissues, which is part of the extracellular fluid (ECF) compartment.

B. It is located within the bloodstream. This describes the intravascular fluid, which is a part of the extracellular fluid (ECF) compartment, not the intracellular fluid (ICF).

C. It is located inside the cells. The intracellular fluid (ICF) is the fluid contained within the cells of the body, making up about two-thirds of the total body water.

D. It is the one containing hormones intended to balance red blood cell count. Hormones related to red blood cell production, such as erythropoietin, are not specific to the intracellular fluid compartment. This statement does not accurately describe the ICF.

A. Heart failure is a common cause of pleural effusion because the heart's inability to pump effectively leads to fluid accumulation in the lungs and pleural space.

B. Severe pulmonary infection, such as pneumonia, can cause inflammation and fluid accumulation in the pleural space, leading to pleural effusion.

C. Pulmonary hypertension: While pulmonary hypertension can cause fluid overload and respiratory issues, it is not a direct cause of pleural effusion.

D. Collagen vascular disease COPD like lupus can cause pleural effusion, but COPD is typically associated with other lung issues like emphysema or chronic bronchitis, not directly with pleural effusion.

E. Emphysema is a chronic lung condition that involves the destruction of alveoli but is not directly related to the development of pleural effusion.
