1. Why are LDLs known as the 'bad' type of cholesterol?

• A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.

2. What is a major goal for home care nurses?

• A. Restoring maximum health function.
• B. Promoting the health of populations.
• C. Minimizing the progress of disease.
• D. Maintaining the health of populations.

Correct answer: A

Rationale: A major goal for home care nurses is restoring maximum health function. This involves helping patients achieve their highest level of health and independence, focusing on individualized care plans tailored to each patient's needs. Choice B, promoting the health of populations, is more aligned with public health nursing rather than home care nursing. Choice C, minimizing the progress of disease, is important but not as comprehensive as restoring maximum health function. Choice D, maintaining the health of populations, is more about preventive care at a population level rather than the individualized care provided by home care nurses.

3. Has Healthy People (HP 2020), issued by the U.S. Department of Health and Human Services, resulted in a reduction of deaths from cardiovascular disease, stroke, and some cancers, as well as decreased dental caries in children aged 2 to 4 years and adults aged 53 to 44 years?

• A. Yes, both statements are true.
• B. No, both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: B

Rationale: Both statements are false. While Healthy People (HP 2020) has contributed to a reduction in deaths from cardiovascular disease, stroke, and some cancers, it did not result in decreased dental caries in children aged 2 to 4 years and adults aged 53 to 44 years. Therefore, the correct answer is B. Choice A is incorrect because the second statement is false. Choice C is incorrect as the first statement is also false. Choice D is incorrect as the second statement is false.

4. Each statement is true, except one. Which is the exception?

• A. Infant formulas should be discontinued at approximately 1 year of age
• B. Low-fat milk is not recommended for children younger than 2 years
• C. Special toddler formulas are available but are unnecessary
• D. Vitamin D-fortified whole milk should not be provided until 2 years

Correct answer: D

Rationale: The correct answer is D. Vitamin D-fortified whole milk should be provided starting at age 1 after discontinuing breast feeding or infant formulas, not at 2 years. Providing whole milk at age 2 is appropriate. Choices A, B, and C are correct statements: infant formulas are typically discontinued around 1 year of age, low-fat milk is not recommended for children under 2 years, and special toddler formulas are unnecessary.

5. Does the reduction in oxidative damage that occurs with energy restriction in animals also occur in people whose diets include _____?

• A. fiber and carbohydrates
• B. fatty acids and protein
• C. probiotics
• D. antioxidants and phytochemicals

Correct answer: D

Rationale: The correct answer is 'antioxidants and phytochemicals'. Antioxidants and phytochemicals help reduce oxidative damage in the body, contributing to healthy aging and a lower risk of chronic diseases. This is the same effect observed in animals when their energy intake is restricted. The other choices are incorrect as there is no direct evidence connecting reduced oxidative damage with diets high in fiber and carbohydrates, fatty acids and protein, or probiotics.
