Answer to Question 1

A
Feedback:
The term antivenin is used to refer to immune sera that have antibodies to venom that might be injected through spider or snake bites. These drugs are used to provide early treatment following exposure to known antigens. They are very specific for antigens to which they can respond. Therefore, options B, C, and D are incorrect.

Answer to Question 2

B
Feedback:
Physical exercise, such as jogging, changes insulin requirements and may result in a delayed hypoglycemic reaction. The fact that he likes to nap before dinner and has an early lunch is unrelated to his hypoglycemia. The patient eating oatmeal early in the morning would help stabilize his blood sugars until later in the morning, but the jogging would have a dramatic effect.
