1. A patient with chronic renal failure should avoid which of the following?

• A. Potassium
• B. Calcium
• C. Iron
• D. Zinc

Correct answer: A

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys play a crucial role in regulating potassium levels in the body. In renal failure, the kidneys may not be able to excrete excess potassium effectively, leading to hyperkalemia. Calcium, iron, and zinc are not typically restricted in chronic renal failure unless there are specific individual circumstances, making them incorrect choices.

2. Which type of anemia is associated with chronic kidney disease?

• A. Iron-deficiency anemia
• B. Vitamin B12 deficiency anemia
• C. Aplastic anemia
• D. Erythropoietin deficiency anemia

Correct answer: D

Rationale: The correct answer is D: Erythropoietin deficiency anemia. Chronic kidney disease often leads to anemia due to decreased production of erythropoietin. This hormone, produced by the kidneys, stimulates red blood cell production in the bone marrow. Iron-deficiency anemia (choice A) is more commonly caused by insufficient dietary iron intake or chronic blood loss. Vitamin B12 deficiency anemia (choice B) is usually due to inadequate dietary intake, malabsorption, or pernicious anemia. Aplastic anemia (choice C) is a bone marrow failure disorder characterized by pancytopenia (decreased red blood cells, white blood cells, and platelets) rather than a deficiency in erythropoietin production.

3. People who use monoamine oxidase inhibitors for the treatment of depression need to avoid foods high in:

• A. Folate
• B. Tyramine
• C. Potassium
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B: Tyramine. Tyramine can interact with monoamine oxidase inhibitors, leading to hypertensive crises. Folate (choice A) is not contraindicated with monoamine oxidase inhibitors. Potassium (choice C) is an essential mineral and not specifically contraindicated with these medications. Vitamin K (choice D) is not a concern for interactions with monoamine oxidase inhibitors.

4. Where do most peptic ulcers occur?

• A. Esophagus
• B. Stomach
• C. Duodenum
• D. Jejunum

Correct answer: C

Rationale: Most peptic ulcers occur in the duodenum, particularly in cases of duodenal ulcers. Peptic ulcers are most commonly found in the duodenum or the first part of the small intestine. While ulcers can also occur in the esophagus and stomach, they are predominantly located in the duodenum. Therefore, options A, B, and D are incorrect.

5. When does short-bowel syndrome usually occur?

• A. The longitudinal muscles of the intestine contract
• B. More than 50% of the small intestine is surgically removed
• C. More than 50% of the large intestine is surgically removed
• D. Transit time is decreased due to infection or drugs

Correct answer: B

Rationale: Short-bowel syndrome typically occurs when more than 50% of the small intestine is surgically removed. This condition leads to malabsorption issues due to the reduced length of the intestine for absorption. Choices A, C, and D are incorrect because short-bowel syndrome specifically relates to the insufficient length of the small intestine, not the contraction of longitudinal muscles, surgical removal of the large intestine, or decreased transit time due to infection or drugs.
