A client with a diagnosis of type 1 diabetes has begun receiving subcutaneous injections of insulin. The nurse knows that insulin allows glucose to enter the body's cells. This is an example of what transport mechanism?
 
  A) Filtration
  B) Passive diffusion
  C) Facilitated diffusion
  D) Active transport

Question 2

When administering an IV solution, the nurse ensures that the solution is placed at least 18 to 24 in. above the site of the infusion. For which of the following reasons should the nurse maintain this position for the IV solution?
 
  A) To ensure that the IV tubing remains free of entanglements
  B) To match the pressure within the client's vein
  C) To infuse the solution into the client's vein slowly
  D) To overcome the pressure within the client's vein

Answer to Question 1

C
Feedback:
Facilitated diffusion is the process in which certain dissolved substances require the assistance of a carrier molecule to pass from one side of a semipermeable membrane to the other. An example is the role that insulin plays in transporting glucose into cells. Filtration involves the movement of water and passive diffusion is dependent on a concentration gradient. Active transport requires an energy source, something which is not the case with insulin and glucose.

Answer to Question 2

D
Feedback:
To overcome the pressure within the client's vein, which is higher than atmospheric pressure, the solution is elevated at least 18 to 24 in. (45 to 60 cm) above the site of the infusion. The height of the solution affects the rate of flow: the higher the solution, the faster the solution infuses, and vice versa. Keeping the solution at a height does not ensure that the IV tubing remains free of entanglements or help to match the pressure in the client's vein.
