1. Mrs. Seva also tells the nurse that she is often constipated. Because she is aging, what physical changes predispose her to constipation?
- A. inhibition of the parasympathetic reflex
- B. weakness of sphincter muscles of anus
- C. loss of tone of the smooth muscles of the colon
- D. decreased ability to absorb fluids in the lower intestines
Correct answer: C

2. What is the primary function of antioxidants in the diet?
- A. Provide energy
- B. Support muscle growth
- C. Neutralize free radicals
- D. Increase blood sugar
Correct answer: C
Rationale: The primary function of antioxidants in the diet is to neutralize free radicals. Free radicals can cause cellular damage, leading to various chronic diseases. Antioxidants help combat this oxidative stress by neutralizing free radicals. Choices A, B, and D are incorrect because antioxidants do not provide energy, support muscle growth, or increase blood sugar; their main role is in combating oxidative stress.
3. What action should the nurse take first for a client with Listeria food poisoning?
- A. Educate the client on safe food practices.
- B. Start a traceback to identify the source of the outbreak.
- C. Report the case to the county board of health.
- D. Ask the client if they have consumed any unpasteurized products.
Correct answer: D
Rationale: Identifying the source of Listeria is crucial for preventing further cases.
4. Which organ produces and secretes bicarbonate ions and insulin?
- A. Stomach
- B. Pancreas
- C. Large intestine
- D. Small intestine
Correct answer: B
Rationale: The pancreas is the correct answer because it performs two vital functions: producing bicarbonate ions to neutralize stomach acid in the small intestine and secreting insulin to regulate blood glucose levels. The stomach is incorrect because its primary function is to break down and digest food, not produce bicarbonate ions or insulin. The large and small intestines are also incorrect because their primary functions are to absorb nutrients and water from food, rather than producing bicarbonate ions or insulin.
5. Cancers that arise from epithelial tissues are known as:
- A. Leukemias
- B. Myelomas
- C. Carcinomas
- D. Sarcomas
Correct answer: C
Rationale: The correct answer is C: Carcinomas. Carcinomas are cancers that originate from epithelial tissues, which are the tissues lining the surfaces of organs and structures in the body. Leukemias (choice A) are cancers of the blood-forming cells, not epithelial tissues. Myelomas (choice B) are cancers that develop in plasma cells in the bone marrow, not epithelial tissues. Sarcomas (choice D) are cancers that arise from connective tissues like bone, cartilage, or muscle, not epithelial tissues. Therefore, choices A, B, and D are incorrect in the context of cancers originating from epithelial tissues.
