Why may patients with hiatal hernia develop anemia?

Correct Answer: B

Rationale: The correct answer is B: Gastritis may cause bleeding. In patients with hiatal hernia, gastritis can occur due to the reflux of stomach acid into the esophagus. This gastritis can lead to gastrointestinal bleeding, resulting in anemia. Choice A is incorrect because iron absorption is not necessarily reduced in hiatal hernia. Choice C is incorrect as iron stores turnover rate is not directly related to the development of anemia in this context. Choice D is incorrect as an aversion to iron-rich foods is not a common reason for anemia in patients with hiatal hernia.

Correct Answer: B

Rationale: The correct answer is B: High blood cholesterol, high blood pressure, and cigarette smoking are three major causes of atherosclerosis. Atherosclerosis is mainly attributed to the buildup of cholesterol-rich plaques in the arteries, high blood pressure causing damage to the arterial walls, and the harmful effects of cigarette smoking on blood vessels. Choices A, C, and D are incorrect because they do not directly relate to the primary causes of atherosclerosis.

Correct Answer: A

Rationale: Aspirin is best absorbed on an empty stomach to maximize its effectiveness. Taking it with cold water helps to enhance absorption. Choice B is incorrect as taking aspirin on a full stomach may reduce its absorption. Choice C is incorrect as fruit juice can sometimes interact with medications. Choice D is incorrect as taking aspirin first thing in the morning may not optimize its absorption.

Correct Answer: A

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys may not effectively filter excess potassium from the blood, leading to hyperkalemia. Calcium, iron, and zinc do not need to be avoided specifically in chronic renal failure unless there are other underlying reasons or complications.

Correct Answer: A

Rationale: A patient with diabetes should be advised to avoid simple carbohydrates. Simple carbohydrates can cause rapid spikes in blood glucose levels due to their quick absorption, which can be challenging to manage for individuals with diabetes. Complex carbohydrates and fiber-rich carbohydrates are generally better choices for individuals with diabetes as they are absorbed more slowly, leading to more stable blood glucose levels. Avoiding all carbohydrates is not necessary or recommended, as carbohydrates are an essential source of energy and nutrients in a balanced diet.
