What symptom would most likely be associated with late dumping syndrome?
- A. abdominal cramps
- B. nausea
- C. diarrhea
- D. confusion
Correct Answer: D

Dental hygienists should not encourage patients with eating disorders such as bulimia to brush immediately after vomiting because self-induced vomiting causes erosion of tooth enamel and dentin hypersensitivity.
- A. Both the statement and the reason are correct and related
- B. Both the statement and the reason are correct but are not related
- C. The statement is correct, but the reason is not correct
- D. The statement is not correct, but the reason is correct
Correct Answer: D
Rationale: The corrected question emphasizes that patients with eating disorders like bulimia should not brush immediately after vomiting as it can worsen enamel erosion due to the acidic content in the mouth. The correct answer is D because patients should rinse with water or a fluoride mouthwash instead of brushing to protect their teeth. Choice A is incorrect because encouraging patients to brush after vomiting is not recommended. Choice B is incorrect as the reason provided is valid but not suitable for the action of encouraging brushing. Choice C is incorrect as the reason for not brushing after vomiting is to prevent enamel erosion.
Almost all (99%) of the calcium in the body is used for?
- A. regulating the transmission of nerve impulses
- B. providing energy for cells
- C. providing rigidity for the bones
- D. regulating muscle contraction
Correct Answer: C
Rationale: The correct answer is C: providing rigidity for the bones. Almost all of the calcium in the body is utilized for maintaining the strength and structure of bones and teeth. Calcium plays a crucial role in skeletal health by providing rigidity and support to the skeletal system. Choices A, B, and D are incorrect because while calcium is essential for various physiological functions like nerve transmission, cell energy production, and muscle contraction, the majority of calcium in the body is primarily allocated for bone health.
What laboratory value would be considered a high-risk measure for coronary heart disease assessment?
- A. triglycerides > 150 mg/dL
- B. BMI > 31
- C. LDL cholesterol < 128 mg/dL
- D. blood pressure of 128/82 mmHg
Correct Answer: B
Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.
Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?
- A. The DRIs replace the older recommended daily allowances
- B. Current DRIs attempt to estimate required nutrients to improve long-term health
- C. DRIs specifically address individuals whose requirements are affected by a disease state
- D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients
Correct Answer: C
Rationale: The correct answer is C. DRIs are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.
