The cell membrane has embedded within it a series of peripheral proteins that function in several ways. One of these proteins is known as a receptor site. What does this receptor site do?
 
  A) Maintains contact with outside proteins to prevent lysis of the cell wall
  B) Maintains contact with inside proteins to prevent lysis of the cell wall
  C) Reacts with specific chemicals inside the cell to stimulate a reaction outside the cell
  D) Reacts with specific chemicals outside the cell to stimulate a reaction within a cell

Question 2

The operating room nurse is developing the care plan for a 10-year-old child with asthma who is scheduled for a tonsillectomy and who will receive halothane as the anesthetic agent. Why is this an appropriate drug for this patient?

  C) Halothane is excreted unchanged in the urine.
  D) Halothane causes an accumulation of secretions.

Answer to Question 1

D
Feedback:
Embedded in the cell membrane are a series of peripheral proteins with several functions. One type of protein located on the cell membrane is known as a receptor site. This protein reacts with specific chemicals outside the cell to stimulate a reaction within a cell. Receptor sites do not prevent lysis of the cell wall nor do they stimulate a reaction outside of the cell.

Answer to Question 2

B
Feedback:
Halothane is of particular benefit to a child with asthma because it dilates bronchi. Halothane is inhaled drug so it is not metabolized in the liver or excreted in the urine. It does not cause an accumulation of secretions.
