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. A client with a large lower-leg ulcer needs protein for wound healing. Which of the following foods should the nurse suggest?

• A. Kidney beans
• B. Grilled salmon
• C. Peanut butter
• D. Raw spinach

Correct answer: B

Rationale: Grilled salmon is the best choice for providing high-quality protein for wound healing. Salmon is rich in essential amino acids, omega-3 fatty acids, and vitamin D, which can help promote tissue repair and reduce inflammation. Kidney beans, peanut butter, and raw spinach are good protein sources but do not offer the same level of high-quality protein and nutrients needed specifically for wound healing.

3. Which mineral is important for the synthesis of thyroid hormones?

• A. Iron
• B. Zinc
• C. Iodine
• D. Magnesium

Correct answer: C

Rationale: Iodine is the correct answer. It is crucial for the synthesis of thyroid hormones by the thyroid gland. Without sufficient iodine, the thyroid cannot produce adequate amounts of hormones, leading to potential issues like hypothyroidism. Iron (Choice A), Zinc (Choice B), and Magnesium (Choice D) do not play a direct role in the synthesis of thyroid hormones, making them incorrect choices for this question.

4. Which condition is most closely associated with a high rate of gastroesophageal reflux disease?

• A. Pregnancy
• B. Anorexia
• C. Hypertension
• D. Diabetes mellitus

Correct answer: A

Rationale: Pregnancy is the correct answer as it is most closely associated with a high rate of gastroesophageal reflux disease (GERD). During pregnancy, the growing fetus exerts pressure on the stomach, leading to the backflow of stomach acid into the esophagus, causing GERD. This physiological change is a common occurrence in pregnant individuals. Conversely, anorexia, hypertension, and diabetes mellitus are not typically linked to a high rate of GERD. While these conditions have their own effects on the body, they do not directly contribute to the mechanisms that cause GERD, unlike the physical changes associated with pregnancy. Therefore, choices B, C, and D are incorrect.

5. A healthcare provider is teaching a client who has constipation about a high-fiber diet. Which of the following foods should be included as sources of fiber? (Select one that does not apply.)

• A. Whole wheat bread
• B. Kidney beans
• C. Refined cereals
• D. Blackberries

Correct answer: C

Rationale: Refined cereals are not a good source of fiber as they have been processed and stripped off most of their fiber content. Whole wheat bread, kidney beans, and blackberries are excellent sources of fiber. Whole wheat bread is made from whole grains, which are high in fiber. Kidney beans are rich in fiber and can help alleviate constipation. Blackberries are a good source of fiber and can aid in promoting bowel regularity.
