Following treatment in an inpatient setting, a client has recovered from cellulitis. The nurse recognizes that the client's recovery is partially attributable to the restoration of the client's biologic defense mechanisms.

What is an example of a mechanical defense mechanism? A) Maintenance of intact skin surfaces
B) Adequate production of appropriate antibodies
C) Secretion of lysozyme in response to microorganisms
D) Synthesis of gastric acid by cells in the stomach

Answer to Question 1

A
Feedback:
Mechanical defense mechanisms are physical barriers that prevent microorganisms from entering the body or expel them before they multiply. Examples include intact skin and mucous membranes. Antibodies, enzymes and secretions are all examples of chemical defense mechanisms.

Answer to Question 2

C
Feedback:
Displacement above the cardiac sphincter is a possible cause of a poorly draining nasogastric tube. An unplugged vent will not cause poor drainage because often nurses remove the cap and restore the port to atmospheric pressure. A drainage container that is filled beyond capacity causes poor draining. Excessive suction does not cause poor drainage.
