Feedback:
Type 1A, or immune-mediated, diabetes involves the autoimmune destruction of pancreatic beta cells and a consequent absolute lack of insulin. Exogenous insulin required as dietary control alone is insufficient. The central problem is an absolute lack of insulin production rather than deranged release.
Answer to Question 2
Ans:
C
Feedback:
Erosive esophagitis can be a complication of hiatal hernias if esophageal acid clearance is significantly impaired. Paraesophageal hiatal hernias are more serious than the sliding variety and require treatment. The root cause of hiatal hernias, herniation of the stomach through the diaphragm, is not normally amenable to treatment with medication. The pyloric sphincter is not associated with hiatal hernias.
