Cardiovascular System Exam Questions

1. 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: Bronchodilators are medications that relax the muscles around the airways, improving airflow and making breathing easier for patients with asthma or COPD. Corticosteroids are anti-inflammatory drugs used to reduce airway inflammation, while mucolytics help in thinning and clearing mucus. Antihistamines are used to treat allergies and not specifically to improve breathing in conditions like asthma or COPD.

2. Which condition involves the tearing of the aorta, leading to severe pain and internal bleeding?

Correct answer: A

Rationale: The correct answer is Aortic dissection. Aortic dissection is a life-threatening condition where the inner layer of the aorta tears, causing severe chest or back pain and internal bleeding, requiring immediate medical attention. Choice B, aneurysm, involves a bulging or weakening of a blood vessel wall, which is different from a tear in the aorta. Choices C and D, stroke and myocardial infarction, do not directly involve the tearing of the aorta and are distinct conditions.

3. The client is given an alpha agonist. What might it be used for?

Correct answer: A

Rationale: Alpha agonists are used for hemostasis to help control bleeding by constricting blood vessels, leading to decreased blood flow to the area. Choices B, C, and D are incorrect as alpha agonists do not typically dilate arteries, dilate veins, or decrease afterload.

4. What is a condition where the walls of the arteries in the lungs become thickened and stiff, leading to increased blood pressure in the pulmonary arteries?

Correct answer: A

Rationale: Pulmonary hypertension is a condition characterized by the thickening and stiffening of the arteries in the lungs, resulting in elevated blood pressure in the pulmonary arteries. This condition is distinct from the other choices provided. Pulmonary fibrosis involves scarring of lung tissue, pulmonary embolism is a blockage in the pulmonary artery, and pulmonary edema is the accumulation of fluid in the lungs.

5. What type of imaging test uses X-rays to visualize the blood vessels after injecting them with a contrast dye?

Correct answer: A

Rationale: Angiography is the correct answer because it is an imaging test that specifically uses X-rays to visualize blood vessels by injecting them with a contrast dye. This procedure is crucial for diagnosing conditions such as blockages or aneurysms. The other options, CT scan, MRI, and ultrasound, do not involve the use of contrast dye to visualize blood vessels with X-rays.
