1. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?

• A. Ionic bond
• B. Covalent bond
• C. Functional group
• D. Metallic bond

Correct answer: A

Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.

2. The parent of a child newly diagnosed with lactose intolerance is being taught by the nurse. Which food items identified by the parent indicate an understanding of foods to avoid?

• A. Popcorn, seeds, and any foods containing nuts.
• B. Milk, cheese, ice cream, and puddings.
• C. Wheat, rye, barley, and commercially baked goods.
• D. Eggs, ham, bacon, and canned meats.

Correct answer: B

Rationale: The correct answer is B. Milk, cheese, ice cream, and puddings contain lactose, which individuals with lactose intolerance should avoid. Choices A, C, and D do not contain lactose and are not typically problematic for individuals with lactose intolerance.

3. A healthcare provider is admitting a client who practices Hinduism. The healthcare provider should identify that which of the following foods is prohibited according to Hindu dietary practices?

• A. Pork
• B. Chicken
• C. Beef
• D. Seafood

Correct answer: C

Rationale: In Hindu dietary practices, beef is prohibited due to religious beliefs. Hindus consider cows to be sacred animals, and therefore consuming beef is strictly forbidden. Pork, chicken, and seafood are not prohibited in Hindu dietary practices, making choices A, B, and D incorrect.

4. Which of the following terms describes the amount of blood ejected per heartbeat?

• A. Stroke volume
• B. Cardiac output
• C. Ejection fraction
• D. Afterload

Correct answer: A

Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.

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.
