A nurse is teaching a client with a recent diagnosis of diabetes about the roles that glucose and insulin play in the disease pathology and the fact that glucose must enter the body cell in order to provide energy for the client.
 
  The nurse knows that which of the following processes allows glucose to enter body cells?
  A)
  Osmosis
  B)
  Facilitated diffusion
  C)
  Active transport
  D)
  Diffusion

Question 2

The health caregiver is explaining the rationale for administering a hypotonic intravenous solution (lower concentration of solutes in its surroundings) to a client.
 
  Which of the following mechanisms of membrane transport most likely underlies this action?
  A)
  Facilitated diffusion
  B)
  Active transport
  C)
  Diffusion
  D)
  Osmosis

Answer to Question 1

Ans:
B

Feedback:

Facilitated diffusion involves the movement of a substance like glucose from an area of high concentration, such as the bloodstream, to an area of low concentration, such as the intracellular space, through the use of a transport protein. Osmosis, active transport, and diffusion do not bring about the movement of glucose into body cells.

Answer to Question 2

Ans:
D

Feedback:

The fact that body cells are permeable to water but not all solute particles, and the amount of solute relative to water content, underlies the choice of intravenous fluid, in health care. Water moves through water channels in a semipermeable membrane along a concentration gradient, moving from an area of higher to an area of lower concentration. This is the essence of osmosis, and the other mechanisms of membrane transport do not have as significant a bearing on the nurse's action.
