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.

What outcome has been shown to be a benefit of breastfeeding that directly impacts the mother?
- A. conserving calcium stores
- B. contracting the uterus
- C. protecting against future hypertension
- D. speeding the resumption of ovulation
Correct Answer: B
Rationale: The correct answer is B, contracting the uterus. Breastfeeding helps contract the uterus after childbirth, reducing postpartum bleeding and helping the uterus return to its pre-pregnancy size more quickly. Choices A, C, and D are incorrect because conserving calcium stores, protecting against future hypertension, and speeding the resumption of ovulation are not direct benefits of breastfeeding to the mother.
Which dietary supplement is often recommended for patients taking statins to lower cholesterol?
- A. Iron
- B. Coenzyme Q10
- C. Calcium
- D. Magnesium
Correct Answer: B
Rationale: Coenzyme Q10 is often recommended for patients on statins because it may help reduce muscle pain, a common side effect of these medications. Iron (Choice A) is not typically recommended for patients taking statins to lower cholesterol. Calcium (Choice C) and Magnesium (Choice D) are not specifically indicated for addressing muscle pain associated with statin use, making them less suitable choices in this scenario.
How many amino acids are essential?
- A. 5
- B. 7
- C. 9
- D. 13
Correct Answer: C
Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.
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.
Which set of guidelines is intended to assess nutrient adequacy or plan intake of a population group, not individuals?
- A. RDA
- B. EAR
- C. DRA
- D. UL
Correct Answer: B
Rationale: The Estimated Average Requirement (EAR) is the correct choice because it is specifically designed to assess the nutrient adequacy of population groups, not individuals. The Recommended Dietary Allowance (RDA) (choice A) is the average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy individuals in a particular life stage and gender group. The Dietary Reference Intake (DRI) (choice C) includes the EAR, RDA, Adequate Intake (AI), and UL, making it a broader set of nutrient reference values. The Tolerable Upper Intake Level (UL) (choice D) is the highest average daily nutrient intake level that is likely to pose no risk of adverse health effects to almost all individuals in the general population.
