1. When is Prevident indicated?
- A. High caries risk
- B. Crown and bridge work
- C. Orthodontic decalcification
- D. All of the above
Correct answer: D
Rationale: Prevident is indicated for all the situations listed in the choices. It is recommended for patients with a high risk of caries to reduce the risk of tooth decay. It is also used in dental procedures like crown and bridge work to strengthen enamel and prevent cavities. Furthermore, it is utilized for orthodontic decalcification to aid in remineralizing the tooth structure and prevent further damage. Therefore, the correct answer is 'All of the above.' While choices A, B, and C are individually correct, selecting 'All of the above' is the most appropriate as it encompasses all the possible indications for Prevident.
2. The ideal time to begin taking folate to prevent neural tube defects is:
- A. Before conception
- B. Once pregnancy begins
- C. At 6 weeks
- D. Upon completion of the first trimester
Correct answer: A
Rationale: Folate is crucial before conception to prevent neural tube defects. Neural tube development occurs early in pregnancy, often before a woman knows she is pregnant.
3. Nutrients that may help decrease high blood pressure levels include:
- A. magnesium and sodium
- B. protein and monounsaturated fat
- C. calcium and potassium
- D. dietary fiber and plant sterols
Correct answer: C
Rationale: Calcium and potassium play vital roles in regulating blood pressure, with potassium helping to balance the negative effects of sodium.
4. Why are blood glucose levels high in type 1 diabetes?
- A. The urinary excretion of glucose is impaired
- B. The lean body mass is metabolized to produce glucose via gluconeogenesis
- C. The absorption of glucose from the gastrointestinal tract is more efficient
- D. There is insufficient insulin to facilitate the transport of glucose into the cells
Correct answer: D
Rationale: In type 1 diabetes, the body's immune system destroys the beta cells in the pancreas that produce insulin. This leads to an insufficient amount of insulin, which is required to facilitate the transport of glucose into the cells. Consequently, blood glucose levels remain high. The other options are incorrect. Option A is incorrect because urinary excretion of glucose does not directly contribute to blood glucose levels. Option B is incorrect because, while gluconeogenesis does produce glucose, it is not the cause of high glucose levels in type 1 diabetes. Option C is incorrect because absorption efficiency of glucose from the gastrointestinal tract does not affect the amount of insulin available to transport glucose into cells.
5. Which of the following statements about Z-Track technique is false?
- A. Z-Track injections prevent irritation of the subcutaneous tissues
- B. The technique involves creating a Zig-Zag like pattern of medication
- C. It forces the medication to be contained in the subcutaneous tissues
- D. It is used when administering Parenteral Iron
Correct answer: B
Rationale: The Z-Track technique is aimed at preventing medication leakage into the surrounding tissues by sealing the medication in the muscle, not by creating a Zig-Zag pattern. Choice A is correct as Z-Track injections help prevent irritation. Choice C is correct as it accurately describes how the technique works. Choice D is also correct as the Z-Track technique is commonly used when administering Parenteral Iron to prevent staining and irritation of the surrounding tissues.
