Nursing Elites

1. Which ethnic group has the lowest rates of type 2 diabetes?

• A. Caucasians
• B. Asian Indians
• C. Pacific Islanders
• D. African Americans

Correct answer: A

Rationale: Statistical data suggest that Caucasians generally have lower rates of type 2 diabetes compared to the other ethnic groups listed in the choices. This is not to say that Caucasians are immune to the disease, but rather that they have fewer reported instances. On the other hand, African Americans and Pacific Islanders are often identified as groups with a significantly higher risk and prevalence of type 2 diabetes. Asian Indians also exhibit higher rates compared to Caucasians. It is important to note that these are general trends observed in statistical data, and individual health outcomes can vary based on various factors such as lifestyle, diet, and genetics, among others. Therefore, the correct answer is A: Caucasians because they generally have the lowest rates of type 2 diabetes when compared to the other ethnic groups mentioned.

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. Which of the following terms describes the amount of blood ejected per heartbeat?

• A. Stroke volume
• B. Cardiac output
• C. Ejection fraction
• D. Afterload

Correct answer: A

Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.

4. Which two dietary components may help decrease blood cholesterol levels?

• A. Omega-3 fatty acids and soluble fiber
• B. Short-chain fatty acids and insoluble fiber
• C. Trans fatty acids and potassium
• D. Cis fatty acids and calcium

Correct answer: A

Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.

5. Which statement about essential nutrients should the nurse include?

• A. Fat-containing foods can help to decrease triglyceride levels.
• B. Animal sources of protein contain 20 essential amino acids.
• C. Carbohydrates are the primary source of fuel for muscles and the brain.
• D. High-fiber foods are a good source of energy.

Correct answer: C

Rationale: The correct answer is C because carbohydrates are indeed the primary source of fuel for muscles and the brain. Choice A is incorrect because while certain fats are essential, they do not help decrease triglyceride levels. Choice B is incorrect because animal sources of protein do not contain all 20 essential amino acids. Choice D is incorrect because although high-fiber foods are important for digestion and overall health, they are not a direct source of energy.
