1. Low levels of high-density lipoproteins (HDL) are?
- A. associated with being underweight
- B. more prevalent in males
- C. highly predictive of CHD risk
- D. not a good predictor of CHD risk
Correct answer: C
Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.
2. A nurse is providing discharge teaching about food choices to a client who has hypokalemia. Which of the following foods should the nurse identify as the best source of potassium?
- A. 1 cup grapes
- B. 1 cup shredded lettuce
- C. 1 cup cooked tomatoes
- D. 1 cup apple slices
Correct answer: C
Rationale: Cooked tomatoes are high in potassium, which is crucial for maintaining normal cell function, nerve transmission, and muscle contraction, making them a suitable choice for addressing hypokalemia. Grapes, shredded lettuce, and apple slices do not contain as much potassium as cooked tomatoes, so they are not the best choice for addressing hypokalemia.
3. Are the following statements both true: 'Most excess energy intake, whether from protein, carbohydrate, alcohol, or fat, is stored in the liver' and 'Fat is a good source of energy, but the preferred fuel is protein'?
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true, but the second is false
- D. The first statement is false, but the second is true
Correct answer: B: Both statements are false
Rationale: Both of the given statements are false. The first statement is inaccurate because the primary location for excess energy storage is not the liver, but rather adipose tissue where it is stored as fat. While the liver does have a role in energy storage and metabolism, it is not the main storage site for excess intake. The second statement is also incorrect. Although fat and protein can be used as sources of energy, the body's preferred source of energy is carbohydrates. They break down more efficiently and are easier for the body to use. The body prefers to conserve protein for other essential functions, such as tissue repair and the production of enzymes. Therefore, protein is not the preferred fuel source.
4. Which types of diabetes are characterized by the body's cells becoming resistant to insulin? (Select all that apply)
- A. Gestational diabetes
- B. Type II diabetes
- C. Type I diabetes
- D. Both A and B
Correct answer: D
Rationale: In both gestational diabetes and Type II diabetes, the body's cells become resistant to insulin, leading to elevated blood glucose levels. Insulin resistance in these types of diabetes prevents glucose from entering the cells, causing it to accumulate in the bloodstream. On the other hand, Type I diabetes is characterized by the body's inability to produce insulin because the immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. Therefore, the correct answer is both A and B. Choice C, Type I diabetes, is not characterized by insulin resistance but rather by the body's inability to produce insulin. Therefore, it is incorrect. Choice D, Both A and B, includes the correct options of gestational diabetes and Type II diabetes, making it the correct answer.
5. A Hazard Analysis and Critical Control Points (HACCP) program would address which element of food service?
- A. cleaning and disinfecting of utensils
- B. developing healthy menus
- C. controlling patient calorie intake
- D. prescribing diets for patients with swallowing problems
Correct answer: A
Rationale: The correct answer is A. Hazard Analysis and Critical Control Points (HACCP) programs are designed to ensure food safety by identifying and controlling potential hazards. This includes addressing the cleaning and disinfecting of utensils to prevent contamination and maintain safe food handling practices. Choices B, C, and D are incorrect because HACCP primarily focuses on preventing food safety hazards rather than developing menus, controlling calorie intake, or prescribing diets for specific medical conditions.
