Answer to Question 1

ANS: B
Russell bodies occur due to excess aggregates of protein. Excess glycogen would affect blood glucose. Increased pigment would not lead to kidney dysfunction. Melanin accumulates in epi-thelial cells (keratinocytes) of the skin and retina.

Answer to Question 2

ANS: C
Early dilation of the endoplasmic reticulum causes the ribosomes to detach from the rough endo-plasmic reticulum, reducing protein synthesis. Aerobic metabolism is a normal process and would not lead to swelling. Cellular swelling will not alter cellular DNA. A reduction in the Na+-K+ pump leads to an intracellular accumulation of sodium and calcium and diffusion of potassium out of the cell. Sodium and water can then enter the cell freely, and cellular swelling results.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
