1. Before Dianne performs the formal research study, what do you call the pre-testing, small-scale trial run to determine the effectiveness of data collection and methodological problems that might be encountered?
- A. Sampling
- B. Pre-testing
- C. Pre-Study
- D. Pilot Study
Correct answer: D
Rationale: The correct answer is 'Pilot Study.' A pilot study is a small-scale trial run conducted before the formal research study to identify and address any issues related to data collection and methodology. This helps in determining the effectiveness of the research process and identifying potential problems that may arise. Choice A, 'Sampling,' refers to the process of selecting a subset of individuals from a larger population for research. Choice B, 'Pre-testing,' simply involves testing something before the main testing phase. Choice C, 'Pre-Study,' is not a commonly used term in research methodology and does not specifically refer to the small-scale trial run described in the question.
2. A common comorbidity in patients with Chronic Kidney Disease (CKD) is:
- A. Liver disease
- B. Malnutrition
- C. Acute renal failure
- D. Difficulty breathing
Correct answer: B
Rationale: Malnutrition is a common comorbidity in patients with Chronic Kidney Disease (CKD). This is mainly due to factors such as dietary restrictions, poor appetite, and the body's increased nutritional needs as it struggles to deal with the disease. Liver disease (Choice A) is not typically associated directly with CKD, although both conditions may coexist in some patients. Acute renal failure (Choice C) is not a comorbidity but a severe and potentially lethal progression of CKD. Difficulty breathing (Choice D) is not a comorbidity but can be a symptom of severe kidney disease or other underlying conditions. However, malnutrition is more commonly observed in CKD patients compared to difficulty breathing.
3. Which nutrient is most important for maintaining fluid balance in the body?
- A. Protein
- B. Sodium
- C. Calcium
- D. Vitamin C
Correct answer: B
Rationale: Sodium plays a key role in maintaining fluid balance and regulating blood pressure.
4. Although a balanced diet is essential for tissue healing and repair, which of the following should the dental hygienist identify as the nutrient of highest priority for a patient with gingivitis or periodontal disease?
- A. Carbohydrates
- B. Vitamin C
- C. Vitamin D
- D. Monosaccharides
Correct answer: B
Rationale: Vitamin C is crucial for collagen production and connective tissue repair, making it a key nutrient for healing gingival tissues in patients with gingivitis or periodontal disease. Carbohydrates are a source of energy and not directly related to tissue repair. Vitamin D is important for bone health but is not the highest priority for gingival tissue healing. Monosaccharides are simple sugars and not as essential for tissue repair as Vitamin C.
5. Which of the following statements are true about iron?
- A. The iron needs of vegans are 20% higher, and the needs of endurance athletes are 10% lower.
- B. It is one of the most common nutrient deficiencies in the world.
- C. Its absorption is increased by Vitamin C and during pregnancy.
- D. Its absorption is increased by tannic acid and calcium in milk.
Correct answer: C
Rationale: Choice C is correct because iron absorption is indeed increased by Vitamin C and during pregnancy. The other choices are incorrect. Choice A is wrong as there are no universally accepted percentages for the iron needs of vegans and endurance athletes. Choice B is inaccurate as iron deficiency is actually one of the most common nutritional deficiencies worldwide. Choice D is incorrect because tannic acid and calcium in milk actually inhibit iron absorption rather than increasing it.
