  Lab results show a high hematocrit due to:
  a. sickle cell syndrome.
  b. fluid movement out of the vascular space.
  c. renal failure.
  d. increased vascular protein secondary to increased metabolism.

Question 2

Answer to Question 1

ANS: B
Fluid and protein movement out of the vascular compartment results in an elevated hematocrit. Sickle cell syndrome does not result in increased hematocrit. Renal failure can occur, but this does not result in an increase in the hematocrit. Protein loss leads to decreased protein, not in-creased.

Answer to Question 2

ANS: A
Male-pattern alopecia is an inherited form of irreversible baldness with hair loss in the central scalp and recession of the frontotemporal hairline. Alopecia areata is an autoimmune T-cell-mediated chronic inflammatory disease directed against hair follicles that results in hair loss. Hirsutism is a form of abnormal hair growth in women. Paronychia is an inflammation of the cuticle.
