Why are antianxiety medications used cautiously in older adults?

Choice A rationale
Antacids can provide temporary relief from the symptoms of an ulcer, but they do not treat the underlying cause if the ulcer is caused by H. pylori.

Choice B rationale
H2-receptor blockers can reduce the amount of acid in the stomach, which can help an ulcer heal, but they do not kill H. pylori bacteria.
Choice C rationale
Antibiotics are used to kill H. pylori bacteria, which is the cause of some ulcers. Therefore, antibiotics are the class of drugs successful in treating an ulcer caused by H. pylori.
Choice D rationale
Proton-pump inhibitors can reduce the production of stomach acid, which can help an ulcer heal, but they do not kill H. pylori bacteria.

Choice A rationale

Hypoglycemia, or low blood sugar, does not trigger the pancreas to secrete insulin. In fact, it’s the opposite. When blood sugar levels are low, the pancreas secretes glucagon, a hormone that signals the liver to release stored glucose into the bloodstream.
Choice B rationale
Hyperglycemia, or high blood sugar, is the primary trigger for the pancreas to secrete insulin. Insulin is a hormone that helps move glucose from the blood into the cells where it can be used for energy. When blood glucose levels rise, such as after a meal, the pancreas releases more insulin.
Choice C rationale
Glucagon is a hormone produced by the pancreas that works with insulin to control blood sugar levels. However, it does not trigger the pancreas to secrete insulin. Instead, glucagon acts when blood sugar levels are low, signaling the liver to release stored glucose into the bloodstream.
Choice D rationale
Ketoacids, or ketones, are substances made when the body breaks down fat for energy. The production of ketones is usually a sign that the body is not getting enough glucose for energy. However, they do not trigger the pancreas to secrete insulin.
