Nursing Elites

1. The small intestine is comprised of the cecum, colon, and rectum. The large intestine includes the duodenum, jejunum, and ileum.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: B

Rationale: Both statements are false. The small intestine consists of the duodenum, jejunum, and ileum, while the large intestine includes the cecum, colon, and rectum.

2. Which outcome has been shown to be most closely associated with breastfeeding infants of mothers who smoke?

• A. poor temperature regulation
• B. vision impairment
• C. vomiting
• D. elevated blood pressure

Correct answer: C

Rationale: The correct answer is C: vomiting. Infants breastfed by mothers who smoke are more likely to experience vomiting and gastrointestinal issues due to the transfer of nicotine and other harmful substances through breast milk. Choices A, B, and D are incorrect. Poor temperature regulation, vision impairment, and elevated blood pressure are not the primary outcomes closely associated with breastfeeding infants of mothers who smoke.

3. How many diet-related major risk factors for coronary heart disease does Mrs. Winslow have?

• A. 1
• B. 4
• C. 2
• D. 3

Correct answer: B

Rationale: Mrs. Winslow has four major diet-related risk factors for coronary heart disease: high total cholesterol, high LDL cholesterol, high triglycerides, and low HDL cholesterol. Choice A is incorrect because there are more than one risk factor present. Choices C and D are incorrect as they do not account for the total number of diet-related major risk factors identified.

4. Which food items should be avoided by a child with lactose intolerance?

• 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 should be avoided by a child with lactose intolerance because they contain lactose, which the child's body may have difficulty digesting. Option A is incorrect as popcorn, seeds, and foods containing nuts do not typically contain lactose. Option C lists wheat, rye, barley, and commercially baked goods, which are sources of gluten, not lactose. Option D includes eggs, ham, bacon, and canned meats, which are also not sources of lactose. Therefore, B is the most appropriate choice for a child with lactose intolerance.

5. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.
