A hospital patient has a large, superficial wound on her elbow that was the result of shearing action when she was moved up in her bed.

The patient's husband mentions that the wound looks infected and irritated because the wound bed is completely red. Which of the following responses would be inappropriate?
A)
Even though it is red, it doesn't mean that the wound is infected.
B)
The red areas show that there is enough circulation to facilitate healing.
C)
Those are fresh blood vessels that are a sign of healthy healing.
D)
A thin sheet of blood clotting is actually desirable and not a sign that your wife's wound is infected.

Question 2

A middle school student is scheduled to receive booster immunizations, and the father asks the nurse why the booster is necessary. What characteristic of the adaptive immune system listed below would provide the rationale for the nurse's response?

A)
Some antibodies require a repeat of the primary immune response.
B)
Some antibodies have a duration measured in months rather than years.
C)
A secondary response causes a sharp rise in antibody levels.
D)
Antigen receptors on CD4+ cells require multiple exposures separated by time.

Answer to Question 1

Ans:
D

Feedback:

Granulation tissue indicates sufficient circulation and angiogenesis associated with healthy wound healing. Granulation tissue consists of new blood vessels, not clotted cellular components.

Answer to Question 2

Ans:
C

Feedback:

Booster immunizations take advantage of the increase in antibodies that accompanies a repeat exposure. The primary immune response cannot be repeated, and antibodies survive beyond several months. Antigen receptors on CD4+ cells do not require multiple exposures.
