1. 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.

2. Which of the following is not true about Pure Experimental research?

• A. There is a control group
• B. There is an experimental group
• C. Selection of subjects in the control group is randomized
• D. There is a careful selection of subjects in the experimental group

Correct answer: D

Rationale: In Pure Experimental research, subjects in the experimental group are typically selected randomly to minimize bias and ensure that the results are attributable to the intervention being studied. Therefore, the statement 'There is a careful selection of subjects in the experimental group' is not true. This careful selection would introduce bias and compromise the validity of the experimental results. Choices A, B, and C are true for Pure Experimental research as it involves both a control group, an experimental group, and randomization of subject selection in the control group to ensure comparability.

3. Medication for treating high blood cholesterol levels should not be used for most people unless:

• A. The patient has at least three major risk factors for coronary heart disease
• B. The patient has been experiencing symptoms of coronary heart disease for at least three months
• C. The patient's medical insurance covers prescription drugs
• D. Treatment with Therapeutic Lifestyle Changes (TLC) alone is unsuccessful after three months

Correct answer: D

Rationale: The correct answer is choice D because medication for high cholesterol is typically not considered unless Therapeutic Lifestyle Changes (TLC), which include diet and exercise, have not proven effective after a three-month period. This approach ensures that lifestyle modifications are given a fair chance to lower cholesterol levels before resorting to medication. Choice A is incorrect because the number of risk factors for coronary heart disease does not dictate when to begin medication; it is about the effectiveness of lifestyle changes. Choice B is incorrect as the duration of coronary heart disease symptoms does not determine when to start medication; the focus is on the response to TLC. Choice C is incorrect because the coverage of prescription drugs by the patient's insurance does not influence the medical decision to use medication for high cholesterol; it is based on medical necessity and effectiveness of prior interventions.

4. A client with nephropathy secondary to diabetes mellitus is receiving dietary teaching from a nurse and plans to make dietary adjustments. Which of the following instructions should the nurse include?

• A. Consume less than 45% of total calories from carbohydrates per day.
• B. Eat no more than 300 mg of cholesterol per day.
• C. Consume less than 0.8 g/kg of body weight of protein per day.
• D. Eat at least 45 g of fiber per day.

Correct answer: D

Rationale: For a client with nephropathy secondary to diabetes mellitus, increasing fiber intake is essential as it can help manage blood sugar levels and improve overall bowel health. Choice A is incorrect because carbohydrates should be controlled but not limited to less than 45% of total calories. Choice B is incorrect as the recommended daily cholesterol intake for individuals with diabetes is less than 200 mg. Choice C is incorrect as protein intake should be individualized based on the client's condition and should not be limited to less than 0.8 g/kg of body weight per day.

5. A condition that often progresses to become type 2 diabetes mellitus is:

• A. type 1 diabetes mellitus
• B. high blood pressure
• C. chronic pancreatitis
• D. impaired glucose tolerance

Correct answer: D

Rationale: Impaired glucose tolerance is a pre-diabetic state characterized by higher than normal blood sugar levels. It is often associated with insulin resistance and can progress to type 2 diabetes mellitus. Type 1 diabetes mellitus (Choice A) is an autoimmune condition where the body attacks insulin-producing cells, leading to a lack of insulin production. High blood pressure (Choice B) and chronic pancreatitis (Choice C) are not directly linked to the progression to type 2 diabetes mellitus.
