1. Low levels of physical activity are more commonly associated with which type of cancer?

A. Esophageal cancer
B. Pancreatic cancer
C. Lung cancer
D. Colon cancer

Correct answer: D

Rationale: Low physical activity is most strongly associated with an increased risk of colon cancer. Regular exercise helps regulate bowel movements and reduce inflammation, which are factors that can contribute to the development of colon cancer. Esophageal cancer, pancreatic cancer, and lung cancer are not as directly linked to low levels of physical activity.

2. What is the primary purpose of dietary fiber in the diet?

A. Improving digestion
B. Providing energy
C. Aiding in the absorption of vitamins
D. Reducing cholesterol

Correct answer: D

Rationale: The primary purpose of dietary fiber in the diet is to reduce cholesterol levels. While it does aid in digestion by promoting regular bowel movements, its main role is in lowering cholesterol. Choice A is partially correct but not the primary purpose. Choice B is incorrect as fiber is not a direct source of energy. Choice C is also incorrect as the primary role of fiber is not in the absorption of vitamins.

3. What percentage of body weight as fat does a woman with a healthy body composition typically average?

A. 5%
B. 15%
C. 25%
D. 35%

Correct answer: C

Rationale: A healthy body fat percentage for women typically ranges between 21% and 33%, with 25% being an average healthy body fat percentage. Choice A (5%) is too low for a healthy body fat percentage and is more in line with essential body fat levels. Choice B (15%) is also lower than the typical range for a healthy body fat percentage. Choice D (35%) is too high and would be considered high body fat for women.

4. What does oliguria lead to in patients with acute kidney injury?

A. Hypophosphatemia and overgrowth of bone tissue
B. An increase in blood potassium levels due to excessive excretion of parathyroid hormone
C. Sodium retention and elevated levels of potassium
D. Edema due to increased urine production

Correct answer: C

Rationale: In patients with acute kidney injury, oliguria (reduced urine output) often results in sodium retention and hyperkalemia (elevated levels of potassium). This is due to the kidneys' decreased capacity to excrete these substances. Choice A is incorrect because hypophosphatemia and overgrowth of bone tissue are not direct consequences of oliguria in acute kidney injury. Choice B is incorrect because an increase in blood potassium levels is not caused by excessive excretion of parathyroid hormone but rather by decreased excretion of potassium. Choice D is incorrect because edema is not caused by increased urine production but rather by fluid overload due to decreased urine output.
