Nursing Elites

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

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

Correct answer: D

Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.

2. The client with infective endocarditis must be assessed frequently by the home health nurse. Which finding suggests that antibiotic therapy is not effective and must be reported by the nurse immediately to the healthcare provider?

• A. Nausea and vomiting
• B. Fever of 103 degrees Fahrenheit (39.5 degrees Celsius)
• C. Diffuse macular rash
• D. Muscle tenderness

Correct answer: B

Rationale: A fever of 103 degrees Fahrenheit indicates that the infection is not under control despite antibiotic therapy. Fever is a common sign of ongoing infection or inadequate response to treatment. Nausea and vomiting, diffuse macular rash, and muscle tenderness are not typically indicative of the effectiveness of antibiotic therapy in treating infective endocarditis.

3. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

4. A client on long-term corticosteroid therapy for rheumatoid arthritis presents with weakness and hypotension. What is the nurse's first action?

• A. Administer a PRN dose of corticosteroids.
• B. Place the client in a supine position.
• C. Encourage oral fluid intake.
• D. Review the client's recent medication history.

Correct answer: A

Rationale: Administering a PRN dose of corticosteroids is the correct first action when a client on long-term corticosteroid therapy presents with weakness and hypotension. In this scenario, the client is likely experiencing adrenal insufficiency due to prolonged corticosteroid use. Administering corticosteroids promptly can help correct this insufficiency and improve the client's symptoms. Placing the client in a supine position may be necessary for symptomatic hypotension, but addressing the root cause with corticosteroids is more crucial initially. Encouraging oral fluid intake is important for many conditions but is not the priority in this case. Reviewing the client's recent medication history can provide valuable information but is not the first action needed to address the client's current presentation.

5. The nurse is providing care for a client with a percutaneous endoscopic gastrostomy (PEG) tube. Which intervention should the nurse implement to prevent complications associated with the tube?

• A. Elevate the head of the bed to 15 degrees during feedings
• B. Aspirate gastric contents before administering medications
• C. Clamp the tube between feedings
• D. Flush the tube with water before and after feedings

Correct answer: D

Rationale: Flushing the PEG tube with water before and after feedings helps prevent clogging and maintains tube patency. Proper flushing is essential for avoiding complications related to tube blockages. Elevating the head of the bed is important for preventing aspiration during and after feedings, not specifically related to PEG tube complications. Aspirating gastric contents before administering medications is not routinely recommended for PEG tube care. Clamping the tube between feedings can lead to tube occlusion and is not a standard practice in PEG tube care.
