1. With which type of cancer is asbestos exposure most strongly associated?

• A. Liver cancer
• B. Peritoneal cancer
• C. Skin cancer
• D. Esophageal cancer

Correct answer: B

Rationale: Asbestos exposure is most strongly associated with peritoneal cancer, a type of cancer that affects the lining of the abdomen. While asbestos can potentially contribute to other types of cancer, there is a significant body of research indicating a robust correlation between asbestos exposure and peritoneal cancer. Asbestos exposure can also lead to mesothelioma, a cancer that affects the lining of the chest. The other options - liver cancer, skin cancer, and esophageal cancer - are not typically associated with asbestos exposure.

2. Which food is recommended for someone with lactose intolerance?

• A. Skim milk
• B. Cheese
• C. Lactose-free yogurt
• D. Whole milk

Correct answer: C

Rationale: Lactose-free yogurt is suitable for individuals with lactose intolerance as it has reduced lactose content.

3. Each statement is true of vitamin K, except one. Which is the exception?

• A. Vitamin K is produced in the gut.
• B. Vitamin K functions as a catalyst for the synthesis of blood-clotting factors.
• C. Vitamin K maintains prothrombin levels.
• D. Vitamin K absorption increases with high levels of vitamin E supplementation.

Correct answer: D

Rationale: The correct answer is D. Vitamin K absorption decreases with high levels of vitamin E supplementation because in larger amounts, vitamin E acts as an anticoagulant. Vitamin K is not produced in the gut but can be obtained from food sources or supplements. Vitamin K is essential for the synthesis of blood-clotting factors and is crucial in maintaining prothrombin levels, which is vital for proper blood clotting. The incorrect choice, D, is misleading as high levels of vitamin E supplementation hinder vitamin K absorption due to its anticoagulant properties. Dental hygienists should be aware of the importance of vitamin K in blood clotting, especially when treating patients who are on anticoagulant medications for conditions like stroke prevention.

4. What is the term for a state of disequilibrium wherein a person cannot readily solve a problem or situation using their usual coping mechanisms?

• A. Crisis
• B. Mental health
• C. Mental illness
• D. Stress

Correct answer: A

Rationale: In psychological terms, a 'Crisis' refers to a state of disequilibrium wherein a person cannot readily solve a problem or situation even by using his usual coping mechanisms. This is different from 'Mental Illness' (Choice C) which is a more general term for a wide range of mental health conditions that affect mood, thinking and behavior. 'Mental Health' (Choice B) is a state of well-being in which an individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and is able to make a contribution to his or her community. Finally, 'Stress' (Choice D) is a state of mental or emotional strain or tension resulting from adverse or demanding circumstances, but it does not necessarily disrupt equilibrium to the extent that usual coping mechanisms are ineffective, unlike 'Crisis'.

5. Begins carb digestion in the mouth:

• A. pepsin
• B. salivary amylase
• C. CCK
• D. secretin
