Which nursing action is appropriate when coaching obese adults enrolled in a behavior modification program?

Correct Answer: B

Rationale: The correct answer is B because asking about situations that tend to increase appetite helps identify triggers for overeating, aiding in behavior modification. This approach targets the root cause of overeating. A is incorrect as focusing solely on caloric intake may not address emotional or situational triggers for overeating. C is incorrect as suggesting rewards like sugarless candy may not address the underlying behaviors contributing to obesity. D is incorrect as eating small amounts frequently may not address the behavioral and psychological aspects of overeating.

Correct Answer: C

Rationale: The correct answer is C: root. The root of a tooth is the portion that lies within the mandible socket, anchoring the tooth in place. The root helps support the tooth and allows for the transfer of nutrients. Dentin (A) is the hard tissue beneath the enamel, crown (B) is the visible part of the tooth above the gumline, and cementum (D) covers the root surface but is not the portion within the mandible socket.

Correct Answer: D

Rationale: The correct answer is D: iron. Ferritin is a protein that binds and stores iron in the liver and blood. It plays a crucial role in regulating iron levels in the body. Glycogen (A) is a storage form of glucose, not stored by ferritin. Lipids (B) are not stored by ferritin either. Vitamin B12 (C) is mainly stored in the liver bound to specific proteins, not ferritin. Iron is the correct answer as it aligns with the main function of ferritin in iron transport and storage.

Correct Answer: A

Rationale: The correct answer is A: lacteals. Lacteals are specialized lymphatic vessels located in the villi of the small intestine. They are responsible for absorbing dietary fats and fat-soluble vitamins. Lymphatics (choice B) are a broader term for lymphatic vessels and nodes. Veins (choice C) are blood vessels that carry deoxygenated blood back to the heart. Arteries (choice D) are blood vessels that carry oxygenated blood away from the heart. Therefore, only lacteals specifically project into the villi and absorb fatty substances, making them the correct choice.

Correct Answer: C

Rationale: The correct answer is C: pepsin. Pepsin is an enzyme produced in the stomach that helps break down proteins into peptides. It works in a highly acidic environment, denaturing proteins. Amylase (A) breaks down carbohydrates, lipase (B) breaks down fats, and maltase (D) breaks down maltose into glucose. Pepsin is specifically designed to target proteins, making it the correct choice.
