1. What is the absorbable unit of a protein?

• A. Amino acid
• B. Pepsin
• C. Glucose
• D. Sucrose

Correct answer: A

Rationale: Amino acids are the correct answer because they are the building blocks of proteins that the body absorbs after digestion. Pepsin, choice B, is incorrect as it is an enzyme that aids in the digestion of proteins, not the absorbable unit of them. Choices C and D, glucose and sucrose, are wrong because they are types of sugars, not proteins.

2. Which risk factors increase the risk of atherosclerosis?

• A. Exercise
• B. Excessive sun exposure
• C. Insufficient vaccinations
• D. Smoking

Correct answer: D

Rationale: Smoking is a major risk factor for atherosclerosis. It significantly contributes to the buildup of plaque in the arteries and thereby increases the risk of cardiovascular diseases. On the other hand, exercise is generally beneficial for cardiovascular health and is not a risk factor for atherosclerosis. Excessive sun exposure and insufficient vaccinations have no established links to atherosclerosis, making them incorrect options for this question.

3. What is the function of villi and microvilli in the GI tract?

• A. produce bile
• B. kill bacteria
• C. produce vitamin K
• D. increase the surface area for absorption

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.

4. The oral cavity is the site of a wide variety of systemic disease manifestations due to:

• A. Rapid cellular turnover
• B. Constant attack by microorganisms
• C. Trauma-intense environment
• D. All of the above

Correct answer: D

Rationale: The oral cavity is indeed the site of various systemic disease manifestations due to multiple factors. Firstly, the rapid cellular turnover in the oral mucosa makes it susceptible to diseases. Secondly, the constant presence of microorganisms in the oral cavity contributes to the development of systemic diseases. Finally, the oral cavity being a trauma-intense environment further increases the risk of systemic manifestations. Therefore, all the provided options - rapid cellular turnover, constant attack by microorganisms, and a trauma-intense environment - play a role in making the oral cavity a site for various systemic diseases. Hence, the correct answer is 'All of the above.' Choices A, B, and C are incorrect individually as they each represent only one aspect of why the oral cavity is prone to systemic disease manifestations, whereas the correct answer encompasses all these factors.

5. Which meal should be removed for a client taking warfarin?

• A. Oriental cabbage salad with chicken
• B. Beef enchilada, rice, and beans
• C. Ham and cheese sandwich
• D. Macaroni salad and grapefruit slices

Correct answer: C

Rationale: The correct meal to remove for a client taking warfarin is the 'Ham and cheese sandwich.' Ham is high in vitamin K, which can interfere with the effectiveness of warfarin, a medication that works by decreasing the clotting ability of the blood. Vitamin K can counteract the effects of warfarin by promoting blood clotting. Choices A, B, and D do not contain high amounts of vitamin K and are therefore safer options for individuals taking warfarin.
