Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?

• A. The client is hyperventilating due to anxiety.
• B. The hypoxic drive was reduced by the oxygen therapy.
• C. The client is experiencing respiratory alkalosis.
• D. The client is experiencing metabolic acidosis.

Correct answer: B

Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.

2. What is the most critical initial intervention for a client who is actively seizing?

• A. Restrain the client to prevent injury
• B. Insert an oral airway
• C. Turn the client to the side
• D. Apply soft restraints to the wrists

Correct answer: C

Rationale: The most critical initial intervention for a client who is actively seizing is to turn the client to the side. This action helps maintain an open airway and prevents aspiration during a seizure. Restrain the client to prevent injury (Choice A) is incorrect because restraining a client during a seizure can lead to injury. Inserting an oral airway (Choice B) is not recommended as it can cause injury and is not necessary during an active seizure. Applying soft restraints to the wrists (Choice D) is also not recommended as it can lead to harm and does not address the immediate airway management needed during a seizure.

3. What pathophysiologic process is producing the symptoms of gout in a client with sudden onset of big toe joint pain and swelling?

• A. Deposition of crystals in the synovial space of the joints produces inflammation and irritation.
• B. Degeneration of joint cartilage causing inflammation.
• C. Infection of the joint space leading to inflammation.
• D. Increased synovial fluid causing joint swelling and pain.

Correct answer: A

Rationale: The correct answer is A. Gout is characterized by the deposition of uric acid crystals in the synovial fluid of joints, which triggers inflammation and pain. This process is known as crystal-induced arthritis. Choice B is incorrect as gout does not involve degeneration of joint cartilage. Choice C is incorrect as gout is not caused by an infection of the joint space. Choice D is incorrect as gout does not result from increased synovial fluid but rather from the deposition of uric acid crystals.

4. The nurse uses a diagram to show that the tetralogy of Fallot involves a combination of four congenital defects. What are the defects?

• A. Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy
• B. Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy
• C. Aortic stenosis, atrial septal defect, overriding aorta, right ventricular hypertrophy
• D. Pulmonary stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy

Correct answer: B

Rationale: The correct answer is B: Pulmonary stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy. Tetralogy of Fallot involves these four congenital defects. Choice A is incorrect because it includes aortic stenosis instead of pulmonary stenosis, atrial septal defect instead of ventricular septal defect, and left ventricular hypertrophy instead of right ventricular hypertrophy. Choice C is incorrect as it includes aortic stenosis and atrial septal defect instead of pulmonary stenosis and ventricular septal defect. Choice D is incorrect because it includes aortic hypertrophy instead of overriding aorta.

5. The nurse is providing discharge teaching for a client with heart failure. Which instruction should be included to prevent fluid overload?

• A. Weigh yourself daily and report a gain of 2 pounds in 24 hours
• B. Increase fluid intake to stay hydrated
• C. Consume a high-sodium diet to retain fluids
• D. Engage in vigorous exercise daily

Correct answer: A

Rationale: The correct answer is A: 'Weigh yourself daily and report a gain of 2 pounds in 24 hours.' Daily weight monitoring is crucial for detecting fluid retention early in clients with heart failure. Reporting a gain of 2 pounds in 24 hours can indicate fluid overload, prompting timely intervention. Choice B is incorrect because increasing fluid intake can exacerbate fluid overload in clients with heart failure. Choice C is incorrect as a high-sodium diet can worsen fluid retention. Choice D is incorrect as vigorous exercise can strain the heart and worsen heart failure symptoms.
