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.

Which of the following nutrients provide energy?(Select ONE that does not apply.)
- A. Carbohydrates
- B. Fats
- C. Protein
- D. Water
Correct Answer: D
Rationale: Carbohydrates, fats, and proteins are the three macronutrients that provide energy (calories) to the body. Carbohydrates are the body's primary source of energy, fats act as a secondary source when carbohydrate energy is exhausted, and proteins are used for energy when carbohydrate and fat sources are low. Choice D, Water, is essential for the body's functions, but it does not provide energy.
Which suggestion is most appropriate to increase calorie intake for a patient with stomach cancer, aiming to prevent weight loss and wasting?
- A. Replace whole fat milk with skim milk or water
- B. Avoid peanut butter and other nuts
- C. Choose high-fat meat instead of lean meat
- D. Limit alcohol intake to two drinks per day
Correct Answer: C
Rationale: The correct answer is C: Choose high-fat meat instead of lean meat. High-fat meats are more calorie-dense than lean meats, which makes them a good choice for increasing calorie intake. This is crucial for patients with stomach cancer who want to avoid weight loss and wasting. Choice A is incorrect because skim milk or water contains fewer calories than whole fat milk. Choice B is also incorrect because peanut butter and nuts are high in calories and therefore should not be avoided when trying to increase calorie intake. Finally, choice D is not a good suggestion to increase calorie intake as alcohol does not provide the necessary nutrients needed for a balanced diet. In fact, excessive alcohol can harm the liver and other organs, and it's not a reliable source of calories.
Why is atherosclerosis dangerous to arterial function?
- A. It diminishes central circulation
- B. It causes decreased blood pressure on artery walls
- C. It narrows the arterial lumen so a clot can easily block it
- D. It increases arterial elasticity
Correct Answer: C
Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
