Answer to Question 1

D
Feedback:
Hageman's factor activates kallikrein, a substance found in the local tissues, which causes the precursor substance kininogen to be converted to bradykinin and other kinins. Bradykinin causes the release of arachidonic acid from the cell membrane. Arachidonic acid causes the release of other substances called autocoids, including prostaglandins, leukotrienes, and thromboxanes

Answer to Question 2

C
Feedback:
Teach the patient to sit upright and press a finger over one nostril to close it. This body position is important to prevent excessive amounts of the medication running down the back of the throat. It needs to be in direct contact with the greatest amount of nasal mucosa and the high Fowler's position provides that.
