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. What factor has been shown to contribute to poor nutritional health among adolescents?

• A. Most teens choose fruit juice and milk over soda
• B. Many teens consume energy drinks on a regular basis
• C. Teens have busy schedules and rarely drink fluids throughout the day
• D. Teens are more likely to consume low-fat milk

Correct answer: B

Rationale: The correct answer is B because many teens regularly consume energy drinks, which can contribute to poor nutritional health due to their high sugar and caffeine content, leading to unhealthy dietary patterns. Choice A is incorrect because choosing fruit juice and milk over soda would generally be considered a healthier choice. Choice C is incorrect as busy schedules leading to inadequate fluid intake might impact hydration but not necessarily poor nutritional health. Choice D is also incorrect as consuming low-fat milk is not typically a significant factor contributing to poor nutritional health among adolescents.

3. What is the name of the record that shows all medications and treatments provided on a repeated basis?

• A. Nursing Health History and Assessment Worksheet
• B. Discharge Summary
• C. Nursing Kardex
• D. Medicine and Treatment Record

Correct answer: D

Rationale: The 'Medicine and Treatment Record' is the document that maintains a comprehensive log of all medications and treatments provided on a routine basis. It does not refer to the 'Discharge Summary', which is a clinical report prepared by healthcare professionals at the end of a hospital stay or series of treatments. The 'Nursing Health History and Assessment Worksheet' is used to gather comprehensive data about the patient's health history and current health status, but it does not record ongoing treatment details. The 'Nursing Kardex' is a patient care information system used to quickly communicate patient needs, but it does not consistently record all medications and treatments provided.

4. What is the first step in the scientific method?

• A. Conduct an experiment
• B. Make an observation and ask a question
• C. Formulate a hypothesis
• D. Reach a consensus

Correct answer: B

Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.

5. On the study “effects of effective nurse-patient communication in decreasing anxiety of post operative patients” What is the Dependent variable?

• A. Effective Nurse-patient communication
• B. Communication
• C. Anxiety level
• D. Post operative patient

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
