Why should a nurse instruct a client with an ileostomy to avoid enteric-coated products?
- A. The coating prevents the absorption of the product.
- B. The coating adversely affects ileostomy.
- C. The coating affects the absorption of vitamins.
- D. The coating causes particularly strong odors.
Correct Answer: A
Rationale: The correct answer is A because enteric-coated products are designed to bypass the stomach and dissolve in the small intestine, where absorption of medications occurs. Since an ileostomy bypasses the large intestine, the medication in enteric-coated products may not be fully absorbed, leading to reduced effectiveness. Choices B, C, and D are incorrect because they do not directly relate to the specific issue of absorption in the context of an ileostomy.

What is the function of the enteric nervous system?
- A. controlling voluntary movements
- B. regulating hormone secretion
- C. controlling digestion independently of the brain
- D. controlling respiratory functions
Correct Answer: C
Rationale: The correct answer is C because the enteric nervous system is a complex network of neurons that controls digestion independently of the brain. It regulates gastrointestinal functions such as peristalsis, secretion of digestive enzymes, and blood flow. This system can operate autonomously but is also influenced by the central nervous system. Choices A, B, and D are incorrect because the enteric nervous system is not responsible for controlling voluntary movements, regulating hormone secretion, or controlling respiratory functions.
Which part of a tooth most closely resembles bone tissue?
- A. enamel
- B. cementum
- C. dentin
- D. gingiva
Correct Answer: C
Rationale: The correct answer is C: dentin. Dentin is the part of the tooth that closely resembles bone tissue because it is a hard, dense tissue similar to bone in composition and structure, providing support and protection to the tooth. Dentin is located beneath the enamel and cementum, forming the bulk of the tooth structure. Enamel (choice A) is the hardest tissue in the body but is not similar to bone tissue in composition. Cementum (choice B) is a hard tissue covering the roots of teeth but is not as similar to bone tissue as dentin. Gingiva (choice D) is the soft tissue that surrounds the teeth and is not similar to bone tissue.
Which action will the nurse include in the plan of care for a patient who is being admitted with Clostridium difficile?
- A. Teach the patient about proper food storag
- C. Order a diet without dairy products for the patient.
- D. Place the patient in a private room on contact isolation.
Correct Answer: D
Rationale: The correct answer is D: Place the patient in a private room on contact isolation. This is important because Clostridium difficile is highly contagious, spread through contact with infected feces. Isolating the patient helps prevent the spread. A: Teaching about food storage is irrelevant to managing C. difficile. B: Administering medications is not mentioned in the question. C: Ordering a diet without dairy is not the priority; isolation is key to prevent transmission.
Mucosa surface cell secretes mucous which provides a physical barrier between __ and __.
- A. Mucosa and Epithelium
- B. Lymph Vessel and lamina Propria
- C. Mucosa and Lumen
- D. Lumen and Epithelium
Correct Answer: C
Rationale: The correct answer is C: Mucosa and Lumen. The mucosa surface cell secretes mucus that forms a physical barrier between the mucosa (inner lining of a cavity or organ) and the lumen (inner space of a tubular structure). This barrier protects the underlying tissues from harmful substances in the lumen.
Choice A (Mucosa and Epithelium) is incorrect because the mucosa is part of the epithelium layer, so it would not make sense for the physical barrier to be between them.
Choice B (Lymph Vessel and Lamina Propria) is incorrect because these structures are not directly related to the secretion of mucus for protection.
Choice D (Lumen and Epithelium) is incorrect because the physical barrier created by the mucus is specifically between the mucosa cells and the lumen, not the epithelium itself.
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?
- A. Hopelessness
- B. Powerlessness
- C. Chronic low self-esteem
- D. Deficient knowledge
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.
