Which statement describes the intracellular fluid (CF) compartment?
It is the one for which capillary membranes become extra permeable during inflammation allowing certain proteins to move to tissues.
It is located within the bloodstream.
It is located inside the cells.
It is the one containing hormones intended to balance red blood cell count.
The Correct Answer is C
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.

Correct Answer is B
Explanation
A. Aortic valve regurgitation: This condition involves the backward flow of blood from the aorta into the left ventricle, not the left atrium.
B. Mitral valve regurgitation occurs when the mitral valve does not close properly, allowing blood to flow back from the left ventricle into the left atrium during systole.
C. Mitral valve stenosis involves the narrowing of the mitral valve, restricting blood flow from the left atrium to the left ventricle, but does not involve backflow into the left atrium.
D. Aortic valve stenosis is the narrowing of the aortic valve, which restricts blood flow from the left ventricle into the aorta, not back into the atrium.
Correct Answer is A
Explanation
A. Shallow and decreased breathing secondary to COPD: The lab values indicate respiratory acidosis, which is characterized by a low pH (acidic), normal bicarbonate levels, and elevated PaCO2. This is consistent with hypoventilation, often seen in conditions like COPD, where shallow breathing leads to CO2 retention.
B. Hyperventilation secondary to a panic attack: Hyperventilation would cause respiratory alkalosis, not acidosis, characterized by a high pH and low PaCO2.
C. Increased renal HCO3 excretion due to kidney disease: This would lead to metabolic acidosis, not respiratory acidosis, and would typically be associated with a low bicarbonate level.
D. Excessive H+ ion loss due to severe vomiting: Severe vomiting causes metabolic alkalosis due to loss of H+ ions, not respiratory acidosis.
