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. Mrs. Pichay who is for thoracentesis is assigned by the nurse to any of the following positions, EXCEPT:

A. straddling a chair with arms and head resting on the back of the chair
B. lying on the unaffected side with the bed elevated 30-40 degrees
C. lying prone with the head of the bed lowered 15-30 degrees
D. sitting on the edge of the bed with her feet supported and arms and head on a padded overhead table

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.

3. A client with frequent kidney stones is receiving dietary teaching from a nurse. Which of the following instructions should the nurse include?

A. Limit your intake of dairy products.
B. Increase your consumption of protein-rich foods.
C. Avoid eating tree nuts, such as almonds.
D. Take a vitamin C supplement twice daily.

Correct answer: A

Rationale: The correct answer is to instruct the client to limit their intake of dairy products. Dairy products are high in calcium and can contribute to kidney stone formation in susceptible individuals. Increasing protein intake may lead to higher excretion of calcium, which can exacerbate kidney stone formation. While tree nuts are high in oxalates, which can contribute to kidney stone formation, it is not the primary concern in this case. Vitamin C supplements can increase oxalate levels in the urine, potentially increasing the risk of kidney stone formation, so it should not be recommended.

4. Which statement by a client indicates a need for further teaching about food safety?

A. I will use the food before the expiration date listed on the package.
B. I will wash my strawberries before I eat them.
C. I will drink unpasteurized milk as it has many gut-healthy probiotics.
D. I will wash my hands after I prepare raw chicken.

Correct answer: C

Rationale: The correct answer is C because drinking unpasteurized milk can contain harmful bacteria, which poses a risk to food safety. Choice A is correct as it emphasizes using food before the expiration date. Choice B is also correct as washing fruits before consumption is a good food safety practice. Choice D is correct as well since washing hands after handling raw chicken is crucial to prevent cross-contamination. Therefore, choice C is the only statement that indicates a need for further teaching on food safety.

5. A patient on a low-sodium diet should avoid which of the following foods?

A. Fresh fruits
B. Unsalted nuts
C. Canned soup
D. Plain rice

Correct answer: C

Rationale: Canned soup is the correct answer. Canned soups are often high in sodium due to added salt and should be avoided on a low-sodium diet. Fresh fruits (Choice A) are typically low in sodium and a good choice for a low-sodium diet. Unsalted nuts (Choice B) are also low in sodium and can be included in a low-sodium diet. Plain rice (Choice D) is a low-sodium food and can be part of a low-sodium diet.
