What is a chronic lung disease that includes chronic bronchitis and emphysema?
- A. Chronic Obstructive Pulmonary Disease (COPD)
- B. Pneumonia
- C. Asthma
- D. Tuberculosis
Correct Answer: A
Rationale: The correct answer is A: Chronic Obstructive Pulmonary Disease (COPD). COPD is a chronic lung disease characterized by chronic bronchitis and emphysema. Chronic bronchitis involves inflammation of the bronchial tubes, leading to excessive mucus production. Emphysema is the destruction of lung tissue, resulting in difficulty breathing. Pneumonia (B) is an acute infection of the lungs. Asthma (C) is a chronic condition characterized by airway inflammation and constriction. Tuberculosis (D) is an infectious disease caused by Mycobacterium tuberculosis affecting the lungs. Therefore, the correct answer is A as it specifically encompasses chronic bronchitis and emphysema, distinguishing it from the other options.

The nurse is administering digoxin to a client with a heart rate of 45 bpm. What is the nurse's priority action?
- A. Hold the digoxin and notify the healthcare provider.
- B. Administer the digoxin as ordered.
- C. Increase the dose of digoxin.
- D. Monitor the client's heart rate and reassess in 30 minutes.
Correct Answer: A
Rationale: The correct answer is A: Hold the digoxin and notify the healthcare provider. Digoxin is a medication that can slow down the heart rate, and a heart rate of 45 bpm is below the normal range. Holding the medication and informing the healthcare provider is the priority to prevent potential harm from further slowing the heart rate. Administering the digoxin as ordered (B) would worsen the bradycardia. Increasing the dose of digoxin (C) would be dangerous. Monitoring the client's heart rate and reassessing in 30 minutes (D) may delay necessary intervention.
The client on digoxin has a potassium level of 3.0 mEq/L. What is the nurse's priority action?
- A. Administer a potassium supplement
- B. Hold the digoxin and notify the healthcare provider
- C. Continue the current digoxin dose
- D. Administer Digibind
Correct Answer: B
Rationale: The correct answer is B: Hold the digoxin and notify the healthcare provider. A potassium level of 3.0 mEq/L can increase the risk of digoxin toxicity as hypokalemia potentiates its effects. Holding the digoxin and informing the healthcare provider allows for further assessment and possible adjustment of the medication regimen. Administering a potassium supplement (A) without adjusting the digoxin dose can still lead to toxicity. Continuing the current digoxin dose (C) without addressing the low potassium level puts the client at risk. Administering Digibind (D) is not necessary at this point as the priority is to address the low potassium level and prevent digoxin toxicity.

The client is prescribed warfarin. What should the client be taught about this medication?
- A. Avoid foods high in vitamin K.
- B. Take the medication with food to prevent stomach upset.
- C. Take the medication at the same time every day.
- D. Increase the dose if a dose is missed.
Correct Answer: A
Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is an anticoagulant that works by decreasing the blood's ability to clot. Vitamin K is essential for blood clotting, so consuming foods high in vitamin K can interfere with the medication's effectiveness. It is important for the client to maintain a consistent intake of vitamin K to ensure the medication works properly. Choices B, C, and D are incorrect because taking warfarin with food, at the same time daily, or increasing the dose if a dose is missed can result in adverse effects or reduced effectiveness of the medication.
Which procedure is used to remove excess fluid or air from the pleural space, helping to relieve pressure on the lungs?
- A. Thoracentesis
- B. Bronchoscopy
- C. Chest X-ray
- D. Arterial blood gas (ABG)
Correct Answer: A
Rationale: Thoracentesis is the correct procedure for removing excess fluid or air from the pleural space. It involves inserting a needle through the chest wall to drain the fluid or air, relieving pressure on the lungs. Bronchoscopy is used to visualize the airways, not remove fluid or air. Chest X-ray is a diagnostic tool for assessing the lungs but does not remove fluid or air. Arterial blood gas (ABG) is a test to assess oxygen and carbon dioxide levels in the blood, not a procedure to remove fluid or air from the pleural space.
