1. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

Correct answer: A

Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.

2. A nurse is discussing denture care with the partner of a client who is unable to perform oral hygiene. Which of the following should be included in the discussion?

Correct answer: C

Rationale: The correct answer is C: 'Wrap gloved fingers with gauze to remove dentures.' This method provides a safe and effective way to remove dentures without causing damage. Choice A is incorrect because flossing dentures is not recommended. Choice B is incorrect as it suggests wiping dentures and storing them dry, which is not the best practice. Choice D is incorrect because using a washcloth may not effectively clean all denture surfaces.

3. A nurse at a provider's office is providing teaching to a client who is taking chemotherapy and losing weight. Which of the following should the nurse recommend to increase calorie and protein intake? (Select one that does not apply.)

Correct answer: D

Rationale: The correct recommendation to increase calorie and protein intake for a client taking chemotherapy and losing weight is to add cream to soups (choice B), as it provides additional calories and proteins. Using milk instead of water in recipes (choice C) can also increase the calorie and protein content. Topping yogurt with fruits (choice A) can be a healthy choice but may not significantly increase calorie and protein intake. Increasing fluids during meals (choice D) may fill up the stomach, potentially reducing the intake of solid foods, which is not ideal when trying to increase calorie and protein consumption.

4. Nutrition therapy for clients with diabetes is based on:

Correct answer: C

Rationale: Corrected Rationale: Nutrition therapy for clients with diabetes should be individualized to each client's lifestyle, preferences, and needs. This approach ensures that the dietary plan is sustainable and tailored to the client, leading to better adherence and improved health outcomes. Choices A and B are too general and do not account for individual differences among clients. Choice D, focusing solely on weight and blood glucose levels, overlooks other crucial aspects of a client's overall well-being and dietary requirements in diabetes management.

5. After reviewing the health and dental histories, the dental hygienist has adequate information to begin dietary counseling with the patient. Providing a standardized, low-carbohydrate menu is sufficient for most patients with a high caries rate.

Correct answer: B

Rationale: Both statements are false. Dietary counseling should be personalized, and a standardized low-carbohydrate menu is not sufficient for all patients.
