What is a condition where the pulmonary arteries become blocked by a blood clot, leading to chest pain, shortness of breath, and other symptoms?
- A. Pulmonary embolism
- B. Pneumothorax
- C. Pulmonary edema
- D. Pulmonary hypertension
Correct Answer: A
Rationale: The correct answer is A: Pulmonary embolism. Pulmonary embolism occurs when a blood clot blocks one of the pulmonary arteries, leading to symptoms like chest pain and shortness of breath. This condition is a medical emergency as it can be life-threatening if not treated promptly.
B: Pneumothorax is the collapse of the lung due to air leaking into the chest cavity, not caused by a blood clot in the pulmonary arteries.
C: Pulmonary edema is the accumulation of fluid in the lungs, causing breathing difficulties, but it is not due to a blood clot in the pulmonary arteries.
D: Pulmonary hypertension is high blood pressure in the arteries of the lungs, not caused by a blockage from a blood clot.
The nurse is caring for a client on digoxin with a heart rate of 48 bpm. What is the nurse's priority action?
- A. Hold the digoxin and notify the healthcare provider.
- B. Administer the digoxin as ordered.
- C. Administer atropine to increase the heart rate.
- D. Increase the dose of digoxin.
Correct Answer: A
Rationale: The correct answer is A: Hold the digoxin and notify the healthcare provider. A heart rate of 48 bpm is below the normal range, indicating bradycardia, a potential side effect of digoxin toxicity. Holding the medication and informing the healthcare provider is crucial to prevent further harm. Administering the digoxin (B) can worsen the bradycardia. Atropine (C) is not the first-line treatment for digoxin-induced bradycardia. Increasing the dose of digoxin (D) can exacerbate toxicity. Overall, prompt action to address the underlying cause is essential in this situation.
Which of the following conditions is identified by a P wave notch in the ECG of a client?
- A. Aortic stenosis
- B. Mitral regurgitation
- C. Aortic regurgitation
- D. Mitral stenosis
Correct Answer: D
Rationale: A P wave notch on an ECG suggests mitral stenosis, indicating delayed conduction through the atria.
What procedure is used to remove fluid from the pleural space to help a patient breathe more easily?
- A. Thoracentesis
- B. Bronchoscopy
- C. Echocardiogram
- D. CT scan
Correct Answer: A
Rationale: The correct answer is A: Thoracentesis. This procedure involves inserting a needle or catheter into the pleural space to drain excess fluid, relieving pressure and allowing the patient to breathe more easily. Bronchoscopy (B) is used to visualize the airways, not remove fluid. Echocardiogram (C) is an ultrasound of the heart, not used for pleural fluid drainage. CT scan (D) is an imaging test, not a procedure for fluid removal. Thoracentesis is the appropriate choice for this scenario.
What is the term for a condition where the lung collapses due to air leaking into the space between the lung and the chest wall?
- A. Pneumothorax
- B. Pleural effusion
- C. Atelectasis
- D. Pulmonary fibrosis
Correct Answer: A
Rationale: The correct answer is A: Pneumothorax. Pneumothorax is the term used to describe a condition where the lung collapses due to air leaking into the pleural space. This causes pressure on the lung, leading to its collapse. Pleural effusion (B) is the accumulation of fluid in the pleural space, not air. Atelectasis (C) is the collapse of a portion or the entire lung due to various reasons but not air leakage. Pulmonary fibrosis (D) is a condition where lung tissue becomes scarred and thickened, not related to air leakage causing lung collapse.
