Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

2. An adult male is brought to the ER after a motorcycle accident with periorbital bruising and bloody drainage from both ears. Which finding requires immediate attention?

• A. Rebound abdominal tenderness.
• B. Diminished breath sounds bilaterally.
• C. Rib pain with deep inspiration.
• D. Projectile vomiting.

Correct answer: D

Rationale: In this scenario, the patient's periorbital bruising and bloody drainage from both ears suggest a severe head injury. Projectile vomiting is a red flag symptom that may indicate increased intracranial pressure, which requires immediate attention to prevent further neurological deterioration. Rebound abdominal tenderness (choice A) typically indicates peritonitis and is not directly related to the primary head injury. Diminished breath sounds bilaterally (choice B) suggest a pneumothorax or hemothorax, which are important but not as immediately life-threatening in this context. Rib pain with deep inspiration (choice C) is concerning for rib fractures or pulmonary contusion, which are also important but do not take precedence over addressing the potential increased intracranial pressure.

3. A client with Addison's disease becomes confused and weak. What is the nurse's first action?

• A. Administer a dose of hydrocortisone immediately.
• B. Check the client’s electrolyte levels.
• C. Administer a dose of normal saline.
• D. Measure the client’s blood pressure in both arms.

Correct answer: A

Rationale: The correct answer is to administer a dose of hydrocortisone immediately. In Addison's disease, confusion and weakness can be signs of an adrenal crisis. Administering hydrocortisone promptly is crucial to prevent further deterioration. Checking electrolyte levels (Choice B) is important but not the first action in managing an acute adrenal crisis. Administering normal saline (Choice C) is not the priority in this situation. Measuring blood pressure in both arms (Choice D) is not the initial action needed to address the client's confusion and weakness in Addison's disease.

4. A client is admitted with a large pleural effusion. Which procedure should the nurse prepare the client for?

• A. Thoracentesis.
• B. Endotracheal intubation.
• C. Chest tube insertion.
• D. Bronchoscopy.

Correct answer: A

Rationale: Corrected Rationale: The correct procedure for a client with a large pleural effusion is thoracentesis. Thoracentesis is a diagnostic and therapeutic procedure used to remove fluid from the pleural space, which can help relieve symptoms associated with pleural effusion. Choice B (Endotracheal intubation) is incorrect as it is a procedure to secure the airway by placing a tube into the trachea. Choice C (Chest tube insertion) is incorrect as it is typically done to drain air or fluid from the pleural space over a longer period. Choice D (Bronchoscopy) is incorrect as it is a procedure used to visualize the airways and diagnose lung conditions, not specifically for pleural effusion removal.

5. 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.
