Cardiovascular System Exam Questions Questions
Question 1 of 5
What test measures the pressure inside the arteries as the heart pumps blood?
Correct Answer: A
Rationale: The correct answer is A: Blood pressure test. This test measures the pressure inside the arteries during the heart's pumping cycle. It assesses systolic and diastolic pressure, indicating the force exerted by blood on artery walls. Pulse oximetry (B) measures oxygen saturation, not arterial pressure. Echocardiogram (C) is an ultrasound that assesses heart structure and function, not arterial pressure. Spirometry (D) measures lung function, not arterial pressure. Therefore, the blood pressure test is the most relevant choice for assessing arterial pressure.
Question 2 of 5
What type of medication is used to relax the muscles around the airways and improve breathing in conditions like asthma and COPD?
Correct Answer: A
Rationale: The correct answer is A: Bronchodilator. Bronchodilators are used to relax the muscles around the airways, allowing them to open up and improve breathing in conditions like asthma and COPD. They work by widening the airways, making it easier to breathe. Corticosteroids (B) reduce inflammation, mucolytics (C) help loosen mucus, and antihistamines (D) are used for allergies and not specifically for relaxing muscles in the airways. Therefore, A is the correct choice for this question.
Question 3 of 5
What is a surgical procedure to remove one of the lobes of the lungs, often performed to treat lung cancer?
Correct Answer: A
Rationale: The correct answer is A: Lobectomy. A lobectomy involves the surgical removal of one of the lobes of the lungs, often performed to treat lung cancer localized in a specific lobe. This procedure allows for targeted removal of cancerous tissue while preserving the remaining healthy lung tissue. Explanation for other choices: B: Pneumonectomy - This involves the complete removal of an entire lung and is not specific to removing a lobe. C: Thoracotomy - This is a surgical incision into the chest, not specific to removing a lobe of the lung. D: Tracheostomy - This is a surgical procedure to create an opening in the neck to insert a tube into the trachea for breathing and is not related to removing a lobe of the lung.
Question 4 of 5
Which type of lung cancer is strongly associated with exposure to asbestos?
Correct Answer: A
Rationale: The correct answer is A: Mesothelioma. Mesothelioma is a type of cancer that affects the lining of the lungs, abdomen, or heart, and is primarily caused by exposure to asbestos fibers. Asbestos exposure is a well-established risk factor for developing mesothelioma. Adenocarcinoma, squamous cell carcinoma, and small cell lung cancer are not typically associated with asbestos exposure. This association is key in determining the correct answer.
Question 5 of 5
What is a surgical procedure to create an opening in the windpipe to assist with breathing?
Correct Answer: A
Rationale: The correct answer is A: Tracheostomy. This surgical procedure involves creating an opening in the windpipe to assist with breathing by bypassing any obstructions in the upper airway. It is commonly performed in cases of severe respiratory distress or when a patient requires long-term mechanical ventilation. Choice B: Lobectomy involves surgical removal of a lobe of the lung and does not directly relate to creating an opening in the windpipe for breathing assistance. Choice C: Thoracotomy is a surgical incision into the chest wall but is not specifically related to creating an opening in the windpipe. Choice D: Pleurodesis is a procedure to treat recurrent pleural effusion by creating adhesions between the layers of the pleura but does not involve creating an opening in the windpipe.
