Answer to Question 1

ANS: D
When hemolysis is intravascular, red cells are lysed within the circulation releasing hemoglobin; this is called hemoglobinemia. If the renal threshold is exceeded, then some hemoglobin may pass through the kidney and thus be found in urine (i.e., hemoglobinuria). Renal tubular epithelial cells where the iron is separated from protoporphyrin take up some hemoglobin passing through the kidney. Some of these renal tubular epithelial cells will gradually be sloughed off into the urine; an iron-specific stain will demonstrate the presence of iron in the form of hemosiderin (as in hemosiderinuria).

Answer to Question 2

ANS: A
The bilirubin originally released from macrophages after degradation of the protoporphyrin ring is normally found in plasma before conjugation in the liver.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
