1. What type of diet would most likely benefit a patient with cystic fibrosis?

• A. Low sodium
• B. Low fat
• C. Clear liquid
• D. High calorie, high protein

Correct answer: D

Rationale: Patients with cystic fibrosis often have malabsorption issues, leading to increased energy needs. A high-calorie, high-protein diet is recommended to help meet these needs, support growth, and maintain overall health. Choices A, B, and C do not address the specific dietary requirements associated with cystic fibrosis, making them less beneficial for these patients.

2. 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.

3. When assessing older adult clients for malnutrition at an adult day care center, which risk factors should the nurse consider?

• A. Dental problems
• B. Depression
• C. Both A and B
• D. Ability to prepare meals

Correct answer: C

Rationale: The correct answer is C: Both A and B. Dental problems and depression are both significant risk factors for malnutrition in older adults. Dental problems can lead to difficulty in chewing and swallowing, resulting in reduced food intake. On the other hand, depression can cause changes in appetite and decreased interest in eating, which can also contribute to malnutrition. Although the ability to prepare meals is important, it is not specifically identified as a risk factor for malnutrition within the context of this question. Therefore, choices A and B are the most appropriate answers.

4. A nurse is caring for a client who is receiving parenteral nutrition. Which of the following findings indicates the therapy is effective?

• A. Client has soft, formed bowel movements.
• B. Client’s mucous membranes are pink.
• C. Client reports ability to complete ADLs.
• D. Client’s blood glucose level is within the expected reference range.

Correct answer: D

Rationale: The correct answer is D because having a blood glucose level within the expected reference range indicates that parenteral nutrition is effectively meeting the client's nutritional needs. Choices A, B, and C are incorrect because soft, formed bowel movements, pink mucous membranes, and the ability to complete activities of daily living do not directly reflect the effectiveness of parenteral nutrition therapy.

5. Which food item interferes with the effectiveness of warfarin?

• A. Cauliflower
• B. Zucchini
• C. Green beans
• D. Broccoli

Correct answer: D

Rationale: Broccoli is high in vitamin K, which can affect the effectiveness of warfarin. Warfarin is an anticoagulant medication that functions by reducing the activity of vitamin K in the body. When one consumes broccoli, which is rich in vitamin K, it could counteract the anticoagulant effect of warfarin, thereby interfering with its effectiveness. On the other hand, cauliflower, zucchini, and green beans do not have significant levels of vitamin K and hence, are not known to impact the effectiveness of warfarin.
