Answer to Question 1

D
Feedback:
Cefadroxil (Duricef) is a cephalosporin. Administration of cephalosporins or carbapenems should be avoided if possible in people with life-threatening allergic reactions to penicillin. Lactulose reduces blood ammonia by resident intestinal bacteria. It is not contraindicated in the event of penicillin anaphylaxis. Ketoconazole is an antifungal and does not possess cross-sensitivity to penicillin. Kanamycin is an aminoglycoside and does not possess cross-sensitivity to penicillin.

Answer to Question 2

A
Feedback:
Myxedema coma is severe, life-threatening hypothyroidism characterized by coma, hypothermia, cardiovascular collapse, hypoventilation, and severe metabolic disorders, such as hyponatremia, hypoglycemia, and lactic acidosis.
