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. The home health nurse visits older adult clients at an assisted living center. Which foods should the nurse recommend to correct the main nutrient deficits for this population?

• A. Carbohydrates
• B. Oily fish and krill oil
• C. Yellow vegetables
• D. Dairy products

Correct answer: D

Rationale: The correct answer is D: Dairy products. Older adults are often deficient in calcium and vitamin D, which are abundant in dairy products. These nutrients are essential for maintaining bone health. Choice A (Carbohydrates) is incorrect because while carbohydrates are an essential nutrient, they are not specifically addressing the main nutrient deficits for older adults. Choice B (Oily fish and krill oil) is incorrect as these foods are sources of omega-3 fatty acids and not specifically addressing the main nutrient deficits common in older adults. Choice C (Yellow vegetables) is incorrect because although vegetables are important for overall health, they do not directly address the main nutrient deficits typically seen in older adults.

3. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?

• A. glucagon
• B. ghrelin
• C. leptin
• D. insulin

Correct answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.

4. Which vitamin is crucial for collagen synthesis and wound healing?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin E
• D. Vitamin K

Correct answer: A

Rationale: The correct answer is Vitamin C. Vitamin C is crucial for collagen synthesis, a process important for wound healing. Collagen is a key protein that helps in wound repair and tissue strength. Vitamin D is primarily known for its role in calcium absorption and bone health, not directly related to collagen synthesis. Vitamin E is an antioxidant that helps protect cells from damage but is not directly involved in collagen synthesis. Vitamin K is essential for blood clotting but does not play a major role in collagen synthesis for wound healing.

5. A healthcare professional is reviewing the lab findings of a client who has Clostridium Difficile. Which of the following findings should indicate to the healthcare professional that the client is experiencing Fluid Volume Deficit?

• A. Hct 53%
• B. Potassium 3.5
• C. Sodium 145
• D. HbA1c 5

Correct answer: A

Rationale: An elevated hematocrit level (Hct 53%) indicates hemoconcentration, a sign of fluid volume deficit. Hct measures the percentage of red blood cells in the blood and increases when there is a decrease in plasma volume, as seen in fluid volume deficit. Choices B, C, and D do not directly relate to fluid volume status. Potassium and sodium levels are more indicative of electrolyte imbalances, while HbA1c reflects average blood sugar levels over the past 2-3 months and is not specific to fluid volume status.
