Answer to Question 1

D
Feedback:
Alteplase (Activase) is used as first-line therapy for the treatment of acute ischemic stroke in selected people. Vitamin K would exacerbate the woman's symptoms, and LMWH and Plavix would be ineffective.

Answer to Question 2

D
Feedback:
Serum sickness is a delayed hypersensitivity reaction most often caused by drugs, such as antimicrobials. Within initial exposure to the antigen, symptoms usually develop within 7 to 10 days and include urticaria, lymphadenopathy, myalgia, arthralgia, and fever. Although the patient has a fever, the patient does not present with all the symptoms of a new infection or sepsis. An autoimmune disease is not likely.
