Nursing Elites

1. Why is atherosclerosis dangerous to arterial function?

• A. It diminishes central circulation
• B. It causes decreased blood pressure on artery walls
• C. It narrows the arterial lumen so a clot can easily block it
• D. It increases arterial elasticity

Correct answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.

2. Which client is most likely to need regular injections of vitamin B12?

• A. The client with malabsorption syndrome.
• B. The client following a vegan eating pattern.
• C. The client whose stomach does not produce intrinsic factors.
• D. The client with alcoholism.

Correct answer: C

Rationale: The correct answer is C. The client whose stomach does not produce intrinsic factors is most likely to need regular injections of vitamin B12. Intrinsic factor is essential for the absorption of vitamin B12. Without intrinsic factor, the client cannot absorb vitamin B12 from food, necessitating the need for regular injections. Choices A, B, and D do not directly impact the production of intrinsic factors in the stomach, so they are less likely to result in the need for vitamin B12 injections.

3. With which of the following should fluoride supplements never be taken?

• A. Water
• B. Juice
• C. Milk
• D. Soda

Correct answer: C

Rationale: Fluoride supplements should never be taken with milk because the fluoride binds with the calcium in the milk, thereby reducing the effectiveness of the fluoride supplement. Other beverages like water, juice, or soda do not share this characteristic as they do not contain the same level of calcium as milk. The rationale behind choosing milk as the correct answer is that it hampers the effectiveness of fluoride supplements, whereas the other choices do not.

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

• A. A single exposure to a large quantity
• B. A single exposure to a small quantity
• C. Multiple exposures of small quantities
• D. Multiple exposures followed by chewing sugarless gum

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.

5. The component that should receive the highest priority before physical examination is the:

• A. Psychological preparation of the client
• B. Physical Preparation of the client
• C. Preparation of the Environment
• D. Preparation of the Equipments

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
