1. Which physiologic role does vitamin C play in the body?

• A. Transcribing DNA to RNA
• B. Absorption and regulation of calcium
• C. Protects integrity of cellular membranes
• D. Catalyst for synthesis of blood-clotting factors

Correct answer: C

Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.

2. Dental hygienists are in a key position to assess and detect signs and symptoms of systemic disease because more than one third of the patients treated in a dental office frequently do not interact with a general health care provider.

• A. Both the statement and the reason are correct and related
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: Dental hygienists often see patients more regularly than general healthcare providers, allowing them to identify systemic issues early.

3. Diseases of the heart and blood vessels are collectively referred to as _____.

• A. Coronary artery disease
• B. Cardiovascular disease
• C. Coronary heart disease
• D. Coronary vessel disease

Correct answer: B

Rationale: The correct term for diseases of the heart and blood vessels is cardiovascular disease. While coronary artery disease (Choice A) specifically involves the narrowing of coronary arteries, it is just one type of cardiovascular disease. Coronary heart disease (Choice C) is also a specific condition related to the heart's blood vessels. Choice D, coronary vessel disease, is not a commonly used term to describe diseases of the heart and blood vessels. Therefore, Choice B, cardiovascular disease, is the most inclusive and appropriate term to refer to these conditions.

4. Which of the following is a tricyclic antidepressant drug?

• A. Venlafaxine (Effexor)
• B. Fluoxetine (Prozac)
• C. Sertraline (Zoloft)
• D. Imipramine (Tofranil)

Correct answer: D

Rationale: Imipramine (Tofranil) is a tricyclic antidepressant drug. This class of medications is used to treat depression, and they work by increasing the levels of certain chemicals in the brain that help lift mood. On the other hand, Venlafaxine (Effexor) is a serotonin and norepinephrine reuptake inhibitor (SNRI), Fluoxetine (Prozac) is a selective serotonin reuptake inhibitor (SSRI), and Sertraline (Zoloft) is also an SSRI. Therefore, they are not classified as tricyclic antidepressants.

5. What type of debridement involves proteolytic enzymes?

• A. Interventional C. Surgical
• B. Mechanical D. Chemical
• C.
• D.

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.
