1. Which systolic blood pressure measurement is classified as prehypertension?
- A. 106 mmHg
- B. 119 mmHg
- C. 130 mmHg
- D. 141 mmHg
Correct answer: B
Rationale: According to the blood pressure classification, a systolic blood pressure between 120-139 mmHg is considered prehypertension. This range indicates an increased risk for developing hypertension if not managed appropriately. Therefore, a systolic blood pressure of 119 mmHg falls into the prehypertension category. A systolic pressure of 106 mmHg is within the normal range, while 130 mmHg and above would be classified as stage 1 and stage 2 hypertension respectively, not prehypertension.
2. An essential nutrient must:
- A. be eaten every day
- B. be obtained by the diet
- C. be water soluble
- D. be eaten at every meal
Correct answer: B
Rationale: The correct answer is B: 'be obtained by the diet.' Essential nutrients are those that the body cannot synthesize in sufficient quantities and must therefore be obtained through the diet. Choice A is incorrect because not all essential nutrients need to be consumed daily; the frequency of consumption varies. Choice C is incorrect because not all essential nutrients are water-soluble; they can be water-soluble or fat-soluble. Choice D is incorrect because essential nutrients do not need to be consumed at every meal, but rather need to be included in the overall diet regularly.
3. What chronic disease has been associated with increased risks of dental problems?
- A. diabetes mellitus
- B. chronic obstructive pulmonary disease
- C. Addison's disease
- D. asthma
Correct answer: A
Rationale: Diabetes mellitus is associated with an increased risk of dental problems, including gum disease and tooth loss, due to high blood sugar levels. While chronic obstructive pulmonary disease (COPD), Addison's disease, and asthma may have oral health implications, diabetes mellitus is specifically known for its strong association with dental issues.
4. What is the glomerular filtration rate for patients with stage 5 chronic kidney disease (CKD)?
- A.
- B.
- C.
- D.
Correct answer: A
Rationale:
5. Can fluid retention cause lab values to be deceptively high, whereas dehydration may cause the values to be deceptively low?
- A. TRUE
- B. FALSE
- C. Not always
- D. Sometimes
Correct answer: B
Rationale: The statement is incorrect. Fluid retention generally results in lab values appearing deceptively low, not high, because the excess fluid dilutes the concentration of substances in the blood. Conversely, dehydration can make lab values appear deceptively high as the reduced fluid volume in the body means substances in the blood are less diluted. Choices 'C: Not always' and 'D: Sometimes' are not specific and do not directly address the statement in the question, hence they are incorrect.
