Nursing Elites

1. What pathophysiological events occur sequentially in the development of atherosclerosis?

• A. Foam cells release growth factors.
• B. Smooth muscle grows over fatty streaks creating fibrous plaques.
• C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
• D. Arterial endothelium injury causes inflammation.

Correct answer: D

Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.

2. A client with multiple sclerosis is receiving intravenous methylprednisolone. What is the nurse's priority action?

• A. Monitor blood glucose levels every 6 hours.
• B. Monitor for signs of infection.
• C. Encourage increased oral fluid intake.
• D. Check the client's temperature every 4 hours.

Correct answer: B

Rationale: When a client with multiple sclerosis is receiving intravenous methylprednisolone, the nurse's priority action is to monitor for signs of infection. Corticosteroids like methylprednisolone can suppress the immune system, increasing the risk of infection. Monitoring for signs of infection allows for early detection and prompt intervention. Monitoring blood glucose levels may be important in clients receiving corticosteroids for prolonged periods, but it is not the priority in this case. Encouraging increased oral fluid intake is generally beneficial but not the priority over monitoring for infection. Checking the client's temperature is important but not the priority action compared to monitoring for signs of infection.

3. A client with peripheral artery disease reports pain while walking. What intervention should the nurse recommend?

• A. Encourage the client to increase physical activity.
• B. Instruct the client to take rest breaks during walking.
• C. Apply warm compresses to the legs to improve circulation.
• D. Massage the affected leg to relieve the pain.

Correct answer: B

Rationale: Clients with peripheral artery disease often experience claudication (leg pain during walking) due to decreased blood flow. Encouraging rest breaks during walking helps to manage pain and improve circulation. Rest breaks allow the muscles to recover from ischemia caused by inadequate blood supply. Increasing physical activity without breaks may worsen the symptoms. Applying warm compresses can potentially lead to burns or skin damage in individuals with compromised circulation. Massaging the affected leg is contraindicated in peripheral artery disease as it can further compromise blood flow.

4. What is the expected outcome of prescribing a proton pump inhibitor to a client with a peptic ulcer?

• A. Promote healing of the gastric mucosa.
• B. Neutralize the effects of stomach acid.
• C. Inhibit the growth of Helicobacter pylori.
• D. Reduce gastric acid secretion.

Correct answer: D

Rationale: The correct answer is D: Reduce gastric acid secretion. Proton pump inhibitors (PPIs) work by reducing gastric acid secretion, which helps prevent further irritation of the gastric mucosa and allows ulcers to heal. While promoting healing of the gastric mucosa (Choice A) is an indirect outcome of reducing gastric acid secretion, the primary mechanism of PPIs is to lower acid levels. Choice B, neutralizing the effects of stomach acid, is typically associated with antacids, not PPIs. Inhibiting the growth of Helicobacter pylori (Choice C) is usually achieved with antibiotics, not PPIs.

5. A 5-week-old infant who developed projectile vomiting over the last two weeks is diagnosed with hypertrophic pyloric stenosis. Which intervention should the nurse plan to implement?

• A. Instruct the mother to give the child sugar water only.
• B. Offer oral rehydration solution every 2 hours.
• C. Provide Pedialyte feedings via nasogastric tube.
• D. Maintain intravenous fluid therapy per prescription.

Correct answer: D

Rationale: The correct intervention for a 5-week-old infant diagnosed with hypertrophic pyloric stenosis and experiencing projectile vomiting is to maintain intravenous fluid therapy. Intravenous fluids are crucial for rehydrating an infant suffering from dehydration due to rapid fluid loss from vomiting. Instructing the mother to provide sugar water only (choice A) is inappropriate and insufficient for rehydration. Offering oral rehydration solution every 2 hours (choice B) may not be effective if the infant continues to vomit. Providing Pedialyte feedings via nasogastric tube (choice C) may also not be as effective as intravenous fluid therapy in rapidly replenishing fluids and stabilizing the child's condition.
