Nursing Elites

1. What is a major constituent of cell membranes?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

2. Which ethnic group has the lowest rates of type 2 diabetes?

• A. Caucasians
• B. Asian Indians
• C. Pacific Islanders
• D. African Americans

Correct answer: A

Rationale: Statistical data suggest that Caucasians generally have lower rates of type 2 diabetes compared to the other ethnic groups listed in the choices. This is not to say that Caucasians are immune to the disease, but rather that they have fewer reported instances. On the other hand, African Americans and Pacific Islanders are often identified as groups with a significantly higher risk and prevalence of type 2 diabetes. Asian Indians also exhibit higher rates compared to Caucasians. It is important to note that these are general trends observed in statistical data, and individual health outcomes can vary based on various factors such as lifestyle, diet, and genetics, among others. Therefore, the correct answer is A: Caucasians because they generally have the lowest rates of type 2 diabetes when compared to the other ethnic groups mentioned.

3. Which vitamin acts most like a hormone?

• A. Vitamin A
• B. Vitamin B
• C. Vitamin D
• D. Vitamin C

Correct answer: C

Rationale: The correct answer is Vitamin D. Although vitamin D, also known as calciferol, has been called a vitamin, it is more appropriately classified as a hormone. Like hormones, vitamin D acts to control the function of other cell types. For example, it helps the body absorb and regulate skeletal calcium and phosphorus levels. Choice A (Vitamin A) plays a crucial role in vision and immune function. Choice B (Vitamin B) is a complex of different vitamins that play various roles in the body. Choice D (Vitamin C) is important for collagen production and acts as an antioxidant.

4. What nursing diagnosis would be most appropriate for a patient with heart failure?

• A. risk for infection
• B. fluid volume excess
• C. impaired body temperature
• D. ineffective airway clearance

Correct answer: B

Rationale: The most appropriate nursing diagnosis for a patient with heart failure is 'fluid volume excess.' In heart failure, the heart's reduced pumping ability leads to fluid retention, causing an excess of fluid in the body. This can result in symptoms such as edema, shortness of breath, and weight gain. 'Risk for infection,' 'impaired body temperature,' and 'ineffective airway clearance' are not the most appropriate nursing diagnoses for a patient with heart failure as they do not directly relate to the pathophysiology and common issues seen in heart failure patients.

5. A nurse is teaching a client who needs to increase their daily fluid intake. Which of the following foods has the highest percentage of water by weight?

• A. Yogurt
• B. Milk
• C. Lettuce
• D. Honey

Correct answer: C

Rationale: The correct answer is Lettuce. Lettuce has the highest percentage of water by weight among the options provided, making it an excellent choice to increase fluid intake. Yogurt and milk have some water content but are not as high in water percentage as lettuce. Honey, on the other hand, contains very little water and is not a good choice for increasing fluid intake.
