1. Which consumption pattern of fermentable carbohydrate is considered most cariogenic?

Correct answer: C

Rationale: Multiple exposures of small quantities are considered most cariogenic. The total amount of dietary fermentable carbohydrate seems to matter less than the form and frequency in which it is consumed. Having multiple exposures of even small quantities of fermentable carbohydrate throughout the day promotes a highly cariogenic environment in the mouth. Choices A and B, involving single exposures, are less cariogenic as they do not sustain the fermentation process over time. Choice D suggests a beneficial practice by chewing sugarless gum after exposures, which can reduce the risk, making it less cariogenic compared to multiple exposures of small quantities.

2. How is the stomach protected from damage by gastric acid?

Correct answer: D

Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.

3. Stimulates secretion of bicarbonate ions and digestive enzymes from the pancreas to the small intestine:

Correct answer: D

Rationale: Secretin stimulates the pancreas to release bicarbonate ions to neutralize stomach acid and digestive enzymes into the small intestine.

4. Health practitioners evaluate disease progression in HIV-infected patients by measuring the concentrations of helper T cells and circulating virus, called _____.

Correct answer: D

Rationale: The viral load is the measure of the amount of circulating virus in the blood and is used to evaluate the progression of HIV infection.

5. Which of the following vaccines is not done by intramuscular (IM) injection?

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.
