Answer to Question 1

C
Feedback:
The inflammatory response will begin with redness in the direct line of the infected wound. Next, swelling will occur because of the fluid that leaks into the tissue as a result of the change in capillary permeability. The heat can be detected due to the increased blood flow to the area. Pain will be felt due to the activation of fibers by histamine and the kinin system as well as stretching of the tissue caused by the edema.

Answer to Question 2

B
Feedback:
Dextromethorphan should not be used in conjunction with MAO inhibitors because hypotension, fever, nausea, myoclonic jerks, and coma could occur. No known drugdrug interaction exists between dextromethorphan and calcium-channel blockers, beta-blockers, and thiazide diuretics.
