1. To raise HDL levels, what is Mrs. Smith advised to do?
- A. quit smoking
- B. increase dietary sodium
- C. take iron supplements
- D. avoid dairy products
Correct answer: A
Rationale: The correct answer is A: quit smoking. Smoking lowers HDL levels, so quitting smoking is crucial to raising HDL levels. Increasing dietary sodium (choice B) is not linked to raising HDL levels and can have negative effects on cardiovascular health. Taking iron supplements (choice C) is not directly related to increasing HDL levels. Avoiding dairy products (choice D) is not necessary to raise HDL levels; in fact, some dairy products like low-fat options can be part of a heart-healthy diet.
2. Which of the following is NOT a physiological role of proteins?
- A. Providing resistance to disease
- B. Regulating fluid balance
- C. Repairing tissue
- D. Serving as the primary source of energy
Correct answer: D
Rationale: Proteins play a diverse range of physiological roles in the body, such as providing resistance to disease, regulating fluid balance, and repairing tissues. However, they are not the primary source of energy for the body. Carbohydrates and fats typically fulfill this role. Therefore, choice D is the correct answer, as it is not a function that proteins perform. Conversely, choices A, B, and C are all physiological functions of proteins, making them incorrect responses to this particular question.
3. A nurse at a health fair is assessing the weight status of four clients. Which of the following clients is classified as overweight?
- A. A female client who has a body mass index of 24
- B. A male client who has a body mass index of 29
- C. A female client who has a waist circumference of 101.6 cm (40 in)
- D. A male client who has a waist circumference of 96.52 cm (38 in)
Correct answer: B
Rationale: A body mass index (BMI) of 25 or higher is classified as overweight. Choice B, a male client with a BMI of 29, falls into the overweight category. Choice A, a female client with a BMI of 24, is within the normal range. Choices C and D provide information on waist circumference, which is not sufficient to determine if a client is overweight or not, as waist circumference alone does not provide the overall picture of weight status compared to BMI.
4. What physiologic role does calcium play in the body?
- A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
- B. Calcium homeostasis, structural integrity of heart muscle
- C. No known metabolic function, caries-preventing properties
- D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance.
Correct answer: A
Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.
5. A client who is postoperative following a liver transplant and weighs 65 kg. Which of the following actions should the nurse plan to take?
- A. Keep the client NPO for the first week postoperative.
- B. Limit caloric content once the client resumes eating.
- C. Stress the importance of safe food-handling practices.
- D. Decrease foods high in carbohydrates once the client resumes eating.
Correct answer: C
Rationale: After a liver transplant, it is crucial to stress the importance of safe food-handling practices to prevent foodborne illnesses, especially due to the client's altered immune system. Keeping the client NPO for the first week postoperative is not recommended as early nutrition support is essential for recovery. Limiting caloric content once the client resumes eating may not be appropriate as they need adequate nutrition for healing. Decreasing foods high in carbohydrates without a specific indication may lead to inadequate nutrient intake, which is not ideal for the client's recovery.
