Cardiovascular System Exam
1. What is the procedure to remove a sample of tissue from the lung for examination under a microscope?
- A. Lung biopsy
- B. Bronchoscopy
- C. Thoracentesis
- D. Lobectomy
Correct answer: A
Rationale: The correct answer is A, lung biopsy. A lung biopsy involves removing a small sample of lung tissue for examination under a microscope to diagnose lung conditions. Choice B, bronchoscopy, is a procedure where a thin, flexible tube with a light and camera is inserted into the airways to view the lungs. This procedure is more for diagnostic purposes and not specifically for tissue removal. Choice C, thoracentesis, is a procedure to remove fluid from the pleural space around the lungs for diagnostic or therapeutic purposes, not for tissue biopsy. Choice D, lobectomy, is a surgical procedure to remove a lobe of the lung, usually done to treat conditions like lung cancer or severe infections, but it does not involve removing tissue for microscopic examination.
2. Which heart chamber receives oxygenated blood from the lungs and pumps it to the rest of the body?
- A. Left atrium
- B. Right atrium
- C. Left ventricle
- D. Right ventricle
Correct answer: C
Rationale: The correct answer is the left ventricle. It receives oxygenated blood from the left atrium and pumps it to the rest of the body through the aorta. The left atrium receives oxygenated blood from the lungs, the right atrium receives deoxygenated blood from the body, and the right ventricle pumps deoxygenated blood to the lungs.
3. Which condition is characterized by a chronic cough that produces mucus, often caused by long-term exposure to irritants?
- A. Chronic bronchitis
- B. Tuberculosis
- C. Asthma
- D. Sinusitis
Correct answer: A
Rationale: Chronic bronchitis is the correct answer. It is characterized by a long-term cough with mucus production, often caused by smoking or prolonged exposure to irritants. Tuberculosis (choice B) is a bacterial infection that primarily affects the lungs but does not usually present with a chronic cough as the main symptom. Asthma (choice C) is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to wheezing and shortness of breath, but it does not typically cause chronic mucus production. Sinusitis (choice D) is inflammation of the sinuses and presents with symptoms like facial pain, nasal congestion, and post-nasal drip, but not specifically a chronic cough with mucus production.
4. The nurse is preparing to administer a beta blocker to a client with hypertension. What is the priority assessment?
- A. Check the client's heart rate.
- B. Check the client's blood pressure.
- C. Check the client's respiratory rate.
- D. Check the client's temperature.
Correct answer: B
Rationale: The correct answer is to check the client's blood pressure. Before administering a beta blocker to a client with hypertension, assessing the blood pressure is crucial because beta blockers can cause hypotension, potentially leading to adverse effects. Checking the heart rate may also be important but is secondary to monitoring the blood pressure in this scenario. Respiratory rate and temperature assessments are not directly related to assessing the client's response to a beta blocker in hypertension management, making choices C and D less relevant.
5. A client on an ACE inhibitor reports a persistent cough. What is the nurse’s best response?
- A. Reassure the client that the cough is a common side effect and is usually not serious.
- B. Instruct the client to report the cough to the healthcare provider as it may require discontinuation of the medication.
- C. Advise the client to use a humidifier at night to relieve the cough.
- D. Suggest the client take an over-the-counter cough suppressant.
Correct answer: B
Rationale: The correct answer is B. A persistent cough in a client on an ACE inhibitor may indicate a serious side effect that requires discontinuation of the medication. Instructing the client to report the cough to the healthcare provider is essential for proper evaluation and management. Choice A is incorrect because simply reassuring the client may delay necessary action. Choice C is incorrect as using a humidifier may not address the underlying cause of the cough. Choice D is incorrect because taking a cough suppressant without healthcare provider guidance may mask symptoms without addressing the cause.
