Nursing Elites

1. A factor contributing to the risk for dehydration in the older adult is that _____.

• A. drinking fluids causes loss of bladder control
• B. older adults do not seem to notice mouth dryness as readily as younger people
• C. increased fluid intake will decrease the intake of nutrient-dense foods
• D. changes in intestinal motility contribute to excess fluid loss

Correct answer: C

Rationale: Older adults may not notice mouth dryness as readily as younger individuals, increasing their risk for dehydration, especially if they do not consciously increase fluid intake.

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

• A. enzymes present in the stomach
• B. a protective bacteria in the stomach
• C. bicarbonate present in the stomach
• D. the mucus lining of the stomach

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. What is your estimate of the population of pregnant woman needing tetanus toxoid vaccination?

• A. 632.5 C. 450.5
• B. 512.5 D. 332.5
• 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.

4. A fire has broken in the unit of DMLM R.N. The best leadership style suited in cases of emergencies like this is:

• A. Autocratic
• B. Participative
• C. Democratic
• D. Laissez Faire

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.

5. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?

• A. Longer exposure leads to an increased risk of demineralization
• B. Longer exposure increases the opportunity for remineralization
• C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
• D. The critical pH at which enamel decalcification occurs is 5.5 or less

Correct answer: B

Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.
