Inflammation is ultimately needed to:
Restore functional cells
Prepare the site for healing
Increase platelets at the site for clotting
Increase inflammatory mediators at the site to vasoconstrict the area
The Correct Answer is B
A. While inflammation plays a role in restoring functional cells, it is not the ultimate goal. The primary purpose of inflammation is to prepare the site for healing, which includes clearing out damaged cells and pathogens.
B. Inflammation is a vital process that helps prepare the site for healing by facilitating the removal of dead tissue and pathogens, allowing for tissue repair. It also promotes the formation of new tissue.
C. Platelet aggregation and clotting are part of the inflammatory process, but the ultimate goal of inflammation is not to increase platelets but to prepare the site for repair and healing.
D. Inflammatory mediators typically cause vasodilation to increase blood flow to the affected area, not vasoconstriction. This helps deliver nutrients, oxygen, and immune cells to the site of injury.

Correct Answer is D
Explanation
A. A pH of 7.50 is alkalotic, and the bicarbonate level is low, which is inconsistent with chronic kidney disease, where metabolic acidosis is more common.
B. The pH of 7.25 indicates acidosis, but the bicarbonate level is too low, and the PaCO2 is too low to be consistent with a typical acid-base imbalance in chronic kidney disease.
C. The pH of 7.55 is alkalotic, which does not fit the typical presentation of chronic kidney disease, which is associated with metabolic acidosis.
D. A pH of 7.30 indicates mild acidosis, and the bicarbonate level is within a normal range for compensatory mechanisms. The elevated PaCO2 of 50 mm Hg indicates respiratory compensation for metabolic acidosis, which is expected in chronic kidney disease, where the kidneys are unable to adequately excrete acid.
Correct Answer is D
Explanation
A. Insulin promotes fat storage and inhibits the breakdown of lipids. Therefore, insulin release would not increase lipid breakdown.
B. Insulin decreases blood glucose levels by facilitating the uptake of glucose into cells for energy production and storage. Insulin does not increase blood glucose levels; it lowers them.
C. Insulin promotes protein synthesis and inhibits protein breakdown, so it would not increase protein breakdown.
D. Insulin lowers blood glucose levels by enhancing glucose uptake into cells, making it the correct answer.
