Mandy, an adolescent girl is admitted to an acute care facility with severe malnutrition. After a thorough examination, the physician diagnoses anorexia nervosa. When developing the plan of care for this client, the nurse is most likely to include which nursing diagnosis?

Correct Answer: C

Rationale: The correct answer is C: Chronic low self-esteem. In anorexia nervosa, individuals often have distorted body image and low self-esteem, which contributes to their disordered eating behavior. By addressing the nursing diagnosis of chronic low self-esteem, the nurse can focus on interventions to help improve the client's self-worth and body image perception. A: Hopelessness may be present in anorexia nervosa but chronic low self-esteem is more directly related to the disorder. B: Powerlessness is not the primary nursing diagnosis in anorexia nervosa; it may be a secondary issue. D: Deficient knowledge is not the main nursing diagnosis in anorexia nervosa; clients generally have knowledge about their condition but struggle with self-image and self-esteem.

Correct Answer: B

Rationale: The correct answer is B: mesentery proper. The mesentery proper consists of two layers of serous membranes with a thin layer of connective tissue between them, and it attaches to the small intestine. This structure provides support and allows for movement of the small intestine. A: The lesser omentum attaches the stomach to the liver, not the small intestine. C: The greater omentum is a large apron-like structure that hangs down from the stomach and covers the intestines, but it does not specifically attach to the small intestine. D: The falciform ligament attaches the liver to the diaphragm and anterior abdominal wall, not the small intestine.

Correct Answer: B

Rationale: The correct answer is B: pulp cavity; root canal. The pulp cavity is the center of the tooth filled with blood vessels and nerves, while the root canal is the cavity within the root of the tooth. This is because the pulp cavity contains the pulp tissue, which includes blood vessels and nerves, providing nourishment and sensation to the tooth. The root canal, on the other hand, is the space within the root where the pulp tissue extends down into. Choices A, C, and D are incorrect because they do not accurately describe the specific structures mentioned in the question.

Correct Answer: D

Rationale: The correct answer is D: sublingual gland. This gland primarily produces mucus, aiding in lubrication and initial digestion. The sublingual gland is located under the tongue. A: The parotid gland primarily produces serous saliva. B: Labial glands are minor salivary glands located in the lips, producing mixed saliva. C: Submandibular gland produces a mixture of serous and mucous saliva.

Correct Answer: A

Rationale: The correct answer is A: gastric pits. Gastric pits are invaginations in the stomach lining that contain specialized cells for secretion of gastric juices. These pits increase the surface area of the stomach by providing a larger area for nutrient absorption and digestion. Plicae circulares are folds in the small intestine, not the stomach. Villi and microvilli are found in the small intestine and further increase surface area for absorption, not in the stomach.
