1. Sugar alcohols have anticariogenic properties and can protect the teeth by decreasing demineralization, enhancing remineralization, or increasing salivary flow, even in the presence of a fermentable carbohydrate. Name 3 sugar alcohols.
- A. Sorbitol
- B. Mannitol
- C. Xylitol
- D. Erythritol
Correct answer: D
Rationale: Sugar alcohols such as sorbitol, mannitol, and xylitol are commonly used in sugar-free products and have properties that help protect teeth from caries by promoting remineralization and increasing salivary flow. Erythritol is another common sugar alcohol used as a sweetener in various products, but it was not listed in the question.
2. Surgery schedules are communicated to the OR usually a day prior to the procedure by the nurse of the floor or ward where the patient is confined. For orthopedic cases, what department is usually informed to be present in the OR?
- A. Rehabilitation department
- B. Laboratory department
- C. Maintenance department
- D. Radiology department
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
3. Which monosaccharide is the most sweet?
- A. Glucose
- B. Dextrose
- C. Fructose
- D. Sucrose
Correct answer: C
Rationale: Fructose is the sweetest of the monosaccharides. Note that glucose and dextrose are the same, and sucrose is a disaccharide, not a monosaccharide.
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. Sickle cell disease is an example of an inherited mistake in the amino acid sequence.
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: A
Rationale: The statement is TRUE. Sickle cell disease is caused by a genetic mutation in the hemoglobin gene, leading to an abnormal amino acid sequence. This results in the production of abnormal hemoglobin molecules, causing red blood cells to become sickle-shaped. This inherited condition is a classic example of a genetic error affecting the amino acid sequence, making choice A the correct answer. Choices B, C, and D are incorrect as they do not accurately reflect the nature of sickle cell disease.
