1. Which organ absorbs water and vitamin K and may be affected by ulcerative colitis?

• A. Stomach
• B. Pancreas
• C. Large intestine
• D. Small intestine

Correct answer: C

Rationale: The large intestine is the organ that is primarily responsible for the absorption of water and vitamin K in the human body. A disease like ulcerative colitis can disrupt these functions by causing inflammation and ulcers in the lining of the large intestine, leading to digestive issues. The stomach (Choice A) primarily functions to break down and digest food, not to absorb water and vitamins. The pancreas (Choice B) secretes enzymes to aid in digestion and hormones to regulate blood sugar, but does not absorb water and vitamins. The small intestine (Choice D) is primarily responsible for absorbing nutrients from digested food, but not specifically water and vitamin K. Therefore, these other choices are incorrect.

2. Approximately 70 to 80 percent of acute pancreatitis cases are caused by gallstones or _____.

• A. infection
• B. alcohol abuse
• C. diabetes
• D. obesity

Correct answer: B

Rationale: Alcohol abuse is indeed a major cause of acute pancreatitis, along with gallstones, accounting for the majority of cases. While infections, diabetes, and obesity can also contribute to pancreatitis, they are not as prevalent as alcohol abuse and gallstones in causing acute pancreatitis.

3. Can soluble fibers be fermented by gut bacteria?

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: Soluble fibers can indeed be fermented by gut bacteria in the large intestine, leading to the production of beneficial short-chain fatty acids. This fermentation process is important for gut health and provides various health benefits. Therefore, the statement is true. Choice B is incorrect as it contradicts the known scientific fact that soluble fibers can be broken down by gut bacteria through fermentation.

4. The principal cation in plasma and interstitial fluid is:

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: The principal cation in plasma and interstitial fluid is sodium. Sodium plays a crucial role in maintaining fluid balance and is the primary cation in extracellular fluids like plasma and interstitial fluid. Potassium is the primary cation within cells, not in extracellular fluids, making it an incorrect choice. Calcium and magnesium are essential minerals but are not the principal cations in plasma and interstitial fluid, so they are also incorrect choices.

5. Much of the research investigating probiotics and intestinal illness has focused on the prevention and treatment of _____.

• A. irritable bowel syndrome
• B. Crohn's disease
• C. diverticulitis
• D. infectious diarrhea

Correct answer: D

Rationale: The correct answer is 'D: infectious diarrhea.' Research has extensively explored the use of probiotics in the prevention and treatment of infectious diarrhea. Probiotics can aid in restoring the balance of gut flora, thereby reducing symptoms. Choices A, B, and C are incorrect because while probiotics may have some benefits for these conditions, the primary focus of research in relation to probiotics and intestinal illness has been on infectious diarrhea.
