1. Because of increasing cases of fluorosis, low levels of fluoride are added to commercial infant formula. Breast milk provides low levels of fluoride.
- 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: D
Rationale: The first statement is false; fluoride is not added to infant formulas due to the risk of fluorosis. The second statement is true; breast milk contains low levels of fluoride.
2. Which of the following should a patient with a history of chronic pancreatitis avoid?
- A. Low-fat dairy
- B. Lean meats
- C. High-fiber vegetables
- D. Alcohol
Correct answer: D
Rationale: The correct answer is D: Alcohol. Alcohol consumption can exacerbate chronic pancreatitis due to its detrimental effects on the pancreas. Conversely, options A, B, and C: Low-fat dairy, Lean meats, and High-fiber vegetables, are generally recommended for patients with chronic pancreatitis. These dietary options are easier on the pancreas and less likely to provoke symptoms. Therefore, they are incorrect choices in this context.
3. A nurse is assessing a client who has malnutrition. Which of the following findings should the nurse expect?
- A. Increased vital capacity
- B. Dry skin
- C. Heat intolerance
- D. Decreased mental status
Correct answer: D
Rationale: Malnutrition can lead to a variety of physical and mental symptoms. One common manifestation of malnutrition is a decreased mental status, which includes confusion, lethargy, and cognitive impairment. Dry skin is a typical finding in malnutrition due to the lack of essential nutrients needed for skin health. Heat intolerance is not a direct consequence of malnutrition. While malnutrition can affect respiratory function, it typically leads to decreased vital capacity rather than increased. Therefore, the correct answer is decreased mental status.
4. An imbalance of which nutrient may elicit delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter?
- A. Zinc
- B. Iron
- C. Sodium
- D. Potassium
Correct answer: B
Rationale: The correct answer is B: Iron. The provided extract mentions that iodine deficiency can cause delayed tooth eruption, enlarged tongue, stillbirths, altered craniofacial growth, sensitivity to cold, dry skin, depression, and goiter. Zinc, Sodium, and Potassium are not associated with these specific symptoms. Zinc deficiency can lead to other health issues but not the ones mentioned. Sodium and Potassium imbalances do not typically result in the symptoms described in the question.
5. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?
- A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
- B. Viscous fiber binds with bile in the intestine and is excreted in feces
- C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
- D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol
Correct answer: B
Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.
