1. Wernicke-Korsakoff syndrome is associated with which vitamin deficiency?

• A. Thiamine (B1)
• B. Riboflavin (B2)
• C. Niacin (B3)
• D. Pyridoxine (B6)

Correct answer: A

Rationale: Wernicke-Korsakoff syndrome is indeed associated with thiamine (vitamin B1) deficiency. This syndrome is commonly seen in individuals with chronic alcoholism due to poor diet and impaired thiamine absorption. Thiamine is essential for normal brain function and energy metabolism. Riboflavin (B2) deficiency can lead to symptoms like sore throat and swollen mucous membranes, not Wernicke-Korsakoff syndrome. Niacin (B3) deficiency causes pellagra, characterized by dermatitis, diarrhea, dementia, and death, but not Wernicke-Korsakoff syndrome. Pyridoxine (B6) deficiency can result in dermatitis, glossitis, and peripheral neuropathy, but it is not associated with Wernicke-Korsakoff syndrome.

2. Which of the following terms refers to a process by which an individual receives education about the recognition of stress reactions and management strategies for handling stress, which may be instituted after a disaster?

• A. Critical incident stress management
• B. Follow-up
• C. Debriefing
• D. Defusion

Correct answer: A

Rationale: Critical incident stress management is a process that provides individuals with education about recognizing stress reactions and strategizing management techniques for handling stress after a disaster. Choice B, 'Follow-up', is incorrect because it generally refers to continuing care after initial treatment, not specifically to stress management education. Choice C, 'Debriefing', is a process where individuals involved in a critical event are brought together to discuss the event and their reactions to it. It can be part of the critical incident stress management process, but it doesn't cover the whole process. Choice D, 'Defusion', is a technique used in the immediate aftermath of a traumatic event to help individuals process their experiences, but it does not encompass the full range of education about stress recognition and management strategies.

3. 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.

4. Which of the following groups of vitamins are fat-soluble?

• A. vitamins B and C
• B. vitamins A and C
• C. vitamins B, E, K, D
• D. vitamins A, E, K, D

Correct answer: D

Rationale: The correct answer is D: vitamins A, E, K, and D. Fat-soluble vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue. Vitamins B and C are water-soluble vitamins and are not stored in the body; any excess amounts are usually excreted in the urine. Therefore, choices A, B, and C are incorrect.

5. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.
