1. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

2. 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.

3. A nurse is caring for a client who has a new prescription for a low-sodium diet. The client's family has requested to bring in some of the client's favorite foods. Which of the following food items should the nurse tell the family members to omit?

• A. Boiled rice
• B. Flat bread
• C. Broiled fish fillet
• D. Pickled vegetables

Correct answer: D

Rationale: The correct answer is 'Pickled vegetables.' Pickled vegetables are high in sodium due to the pickling process, making them unsuitable for a low-sodium diet. Boiled rice, flat bread, and broiled fish fillet are generally lower in sodium compared to pickled vegetables and can be included in a low-sodium diet. Therefore, the nurse should advise the family to omit pickled vegetables to adhere to the client's dietary restrictions.

4. The type of medicine that proposes that a person's inherent "life force" can foster self-healing is known as _____ medicine.

• A. homeopathic
• B. integrative
• C. naturopathic
• D. Ayurvedic

Correct answer: C

Rationale: Naturopathic medicine is based on the belief that a person's inherent "life force" can promote self-healing, often using natural therapies and lifestyle changes.

5. Metabolic control is especially important for women with gestational diabetes to ensure the infant does not develop:

• A. microsomia
• B. macrosomia
• C. type 1 diabetes
• D. type 2 diabetes

Correct answer: B

Rationale: Metabolic control is crucial for women with gestational diabetes to prevent the development of macrosomia, which is characterized by an abnormally large baby. This condition poses risks such as birth injuries and necessitates careful management of blood sugar levels. Microsomia is not a known term related to this context. Type 1 and type 2 diabetes are not conditions the infant would develop as a result of gestational diabetes in the mother.
