Nursing Elites

1. Which factor has been shown to increase the risk of development of atherosclerosis?

• A. Menopause
• B. Age older than 35
• C. Increased levels of arachidonic acid
• D. Elevated HDL cholesterol

Correct answer: A

Rationale: The correct answer is A: Menopause. Menopause is associated with an increased risk of atherosclerosis due to hormonal changes that affect lipid profiles and vascular health. Conversely, B: Age older than 35 is not necessarily a risk factor for atherosclerosis on its own, though atherosclerosis risk does generally increase with age. C: Increased levels of arachidonic acid is not specifically linked to atherosclerosis; it's a fatty acid that can be both beneficial and harmful to health depending on its metabolic pathway. D: Elevated HDL cholesterol is actually beneficial rather than harmful because HDL cholesterol is known as 'good' cholesterol that helps to reduce the risk of heart disease and atherosclerosis.

2. Which of the following are examples of mechanical digestion? Select all that apply.

• A. Heat
• B. Segmentation
• C. Option B and D
• D. Peristalsis

Correct answer: C

Rationale: Mechanical digestion involves physical movements that break down food in the digestive tract. Segmentation (choice B) and peristalsis (choice D), which are both movements of the muscles in the digestive tract, are examples of this type of digestion. Heat (choice A), on the other hand, is related to chemical digestion, not mechanical digestion. Therefore, choice C (Option B and D) is the correct answer as it includes both examples of mechanical digestion provided in the choices. Choices A and D are incorrect because heat (choice A) is not a mechanical digestion process, and peristalsis (choice D) is a movement that helps propel food along the digestive tract but is not directly involved in breaking down food physically.

3. Which group is least susceptible to insufficient intake of protein?

• A. The elderly
• B. Individuals with low income
• C. Adults participating in endurance exercise
• D. Patients who are chronically ill

Correct answer: C

Rationale: Adults who participate in endurance exercise are typically more aware of their nutritional needs and have higher protein intake compared to other groups. The rationale behind why the other choices are incorrect is as follows: A: The elderly are often at a higher risk of insufficient protein intake due to various factors such as reduced appetite, dental issues, and decreased muscle mass. B: Individuals with low income may struggle to afford protein-rich foods, making them more susceptible to insufficient protein intake. D: Patients who are chronically ill may have specific dietary restrictions or challenges that can lead to inadequate protein consumption.

4. A nurse is developing a program about strategies to prevent foodborne illnesses for a community group. The nurse should plan to include which of the following recommendations? (Select one that does not apply).

• A. Keep cold food temperatures below 4.4�C (40�F).
• B. Reheat leftovers before eating.
• C. Wash raw vegetables thoroughly in clean water.
• D. Keep cooked foods at 48.9�C (120�F).

Correct answer: D

Rationale: The correct answer is to keep cooked foods at 48.9�C (120�F). This temperature is too low to keep cooked foods safe from bacterial growth. The ideal temperature to keep cooked foods safe is above 60�C (140�F). Choices A, B, and C are all important strategies to prevent foodborne illnesses. Keeping cold food temperatures below 4.4�C (40�F) helps prevent bacterial growth, reheating leftovers before eating kills any bacteria that may have grown during storage, and washing raw vegetables thoroughly in clean water helps remove dirt and bacteria.

5. In which type of shock does the patient experience a mismatch of blood flow to the cells?

• A. Distributive
• B. Cardiogenic
• C. Hypovolemic
• D. Septic

Correct answer: A

Rationale: The correct answer is A: Distributive shock. Distributive shock is characterized by a widespread increase in vascular permeability leading to a relative hypovolemia and a mismatch of blood flow to the cells. Choice B, Cardiogenic shock, is due to the heart's inability to pump effectively. Choice C, Hypovolemic shock, results from a decrease in intravascular volume. Choice D, Septic shock, is caused by a systemic response to infection.
