1. 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

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.

2. Which practice is a type of traditional Chinese medicine?

• A. magnet therapy
• B. acupuncture
• C. faith healing
• D. biofeedback

Correct answer: B

Rationale: Acupuncture is a key practice in traditional Chinese medicine. It involves the insertion of thin needles into specific points on the body to balance energy flow and promote healing. Magnet therapy, faith healing, and biofeedback are not specifically associated with traditional Chinese medicine practices.

3. How is the stomach protected from damage by gastric acid?

• A. enzymes present in the stomach
• B. a protective bacteria in the stomach
• C. bicarbonate present in the stomach
• D. the mucus lining of the stomach

Correct answer: D

Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.

4. A client at risk for iron-deficiency anemia is being taught by a nurse about optimizing dietary intake of iron. The nurse should explain that which of the following sources of iron is easiest for the body to absorb?

• A. Spinach
• B. Cantaloupe
• C. Chicken
• D. Lentils

Correct answer: C

Rationale: The correct answer is 'Chicken.' Chicken contains heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like spinach, cantaloupe, and lentils. Heme iron, as present in chicken, is more bioavailable and is better absorbed by the body, making it an excellent source of iron for individuals at risk of iron-deficiency anemia. Spinach, cantaloupe, and lentils contain non-heme iron, which is not as efficiently absorbed as heme iron.

5. A nurse is teaching a nutrition class for clients who have type 2 diabetes mellitus. Which of the following statements should the nurse include about management of acute illness?

• A. Consume carbs every 3-4 hrs
• B. Decrease fluid intake to 1000 mL per day
• C. Monitor blood glucose twice per day
• D. Check urine for ketones every 24 hrs

Correct answer: A

Rationale: The correct statement is to 'Consume carbs every 3-4 hours.' During acute illness, it is important to maintain a consistent carbohydrate intake to help manage blood glucose levels for clients with type 2 diabetes. This frequent consumption can prevent hypoglycemia and provide energy needed during illness. Decreasing fluid intake (choice B) is not recommended during acute illness, as hydration is crucial to prevent complications. Monitoring blood glucose (choice C) more frequently than twice a day is necessary during acute illness. Checking urine for ketones (choice D) should be done more frequently than once every 24 hours during illness to monitor for diabetic ketoacidosis.
