[gbarreiro]

When a nurse is checking the urinalysis, plasma proteins should be absent from the urine because:
 
  a. all filtered proteins are subsequently reab-sorbed.
  b. the texture of the covering surrounding plasma proteins interferes with reabsorp-tion.
  c. filtered proteins are subsequently degrad-ed before elimination.
  d. the negative charge of the glomerular fil-tration membrane repels the plasma pro-teins.

Question 2

When discussing the functional unit of the kidney, what term should the nurse use?
 
  a. Calyx
  b. Nephron
  c. Collecting duct
  d. Pyramid

Answer to Question 1

ANS: D
Like other capillary membranes, the glomerulus is freely permeable to water and relatively im-permeable to large colloids, such as plasma proteins. The molecule's size and electrical charge af-fect the permeability of substances crossing the glomerulus. Protein filtration is not as dependent on size, texture, or on degradation.

Answer to Question 2

ANS: B
The functional unit of the kidney is the nephron. The nephron does not serve the same function as the calyx, the collecting duct, or the pyramid.
