Q2. Correct Answer: D
This patient is on nadolol, a nonselective beta-blocker, for the primary prophylaxis of large esophageal varices. The dose of nonselective beta-blockers should be increased in a stepwise manner until the maximum tolerated dose or until a resting heart rate of 50-55/min is met. Since this patient is already at target heart rate, there is no indication to increase the dose. Repeat endoscopy is not indicated to assess change in size of varices once initiated on nonselective beta-blockers and at target heart rate. The choice between beta-blockers or endoscopic variceal ligation depends on local resources and expertise, patient preference and characteristics, side effects, and contraindications. Carvedilol, a nonselective beta-blocker with vasodilatory properties, is a promising alternative therapy that deserves further evaluation. However, given that nadolol has achieved target heart rate and patient is tolerating it, there is no indication to change management.
