Answer to Question 1

Correct Answer: 3
Rationale 1: Cholestatic hepatitis is an adverse effect associated with erythromycin estolate, a macrolide.
Rationale 2: Acute pancreatitis is not associated with tetracycline therapy.
Rationale 3: Pruritus, or itching, and jaundice, a yellowish discoloration of the skin, are associated with fatty degeneration of the liver, a serious adverse effect of tetracycline.
Rationale 4: Exfoliative dermatitis is an adverse effect associated with tetracycline. However, it is associated with pruritus, not jaundice.
Global Rationale: Serious adverse reactions of tetracycline include anaphylaxis; fatty degeneration of the liver, producing jaundice; and exfoliative dermatitis. Cholestatic hepatitis is an adverse effect associated with erythromycin estolate, a macrolide. Acute pancreatitis is not associated with tetracycline therapy. Exfoliative dermatitis is an adverse effect associated with tetracycline. However, it is associated with pruritus, not jaundice.
