Answer to Question 1

C
This patient has hypothyroidism and should be treated with levothyroxine. Methimazole is a thyroid suppressant. Liothyronine is synthetic T3 . Propylthiouracil is a thyroid suppressant.

Answer to Question 2

B
The guidelines for treatment of diarrhea emphasize comprehensive evaluation before treatment begins. Antibiotic use points to C. difficile as a possible cause, and metronidazole is often used to treat mild to moderate infection. Vancomycin is used when C. difficile is severe. Diphenoxylate can worsen the infection because it slows transit time of the bacteria in the gut. Prolonged diarrhea during antibiotic therapy should be investigated.
