Cardiovascular System Exam Questions And Answers
1. What is the narrowing of the arteries due to the buildup of plaque, which can lead to heart attacks and strokes?
- A. Coronary artery disease
- B. Peripheral artery disease
- C. Aortic stenosis
- D. Mitral valve prolapse
Correct answer: A
Rationale: Coronary artery disease is the correct answer. It is the narrowing or blockage of the coronary arteries due to plaque buildup, which can lead to heart attacks and other cardiovascular issues. Choice B, Peripheral artery disease, involves the narrowing of arteries in the limbs, not specifically the coronary arteries. Choice C, Aortic stenosis, refers to the narrowing of the aortic valve opening, not the arteries. Choice D, Mitral valve prolapse, is a condition where the valve between the left atrium and left ventricle doesn't close properly, unrelated to arterial narrowing.
2. The client is being taught about the use of warfarin. What is the most important dietary instruction?
- A. Avoid foods high in vitamin K.
- B. Increase the intake of vitamin K-rich foods.
- C. Avoid foods high in protein.
- D. Increase the intake of foods high in calcium.
Correct answer: A
Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is a medication that works by decreasing the activity of vitamin K in the body to prevent blood clotting. Therefore, consuming foods high in vitamin K like green leafy vegetables can interfere with the medication's effectiveness. Choices B, C, and D are incorrect. Increasing the intake of vitamin K-rich foods would counteract the effects of warfarin. Avoiding foods high in protein or increasing the intake of foods high in calcium are not specifically related to the use of warfarin.
3. Which condition is characterized by fluid collection in the lungs, making it difficult to breathe?
- A. Pulmonary edema
- B. Pleurisy
- C. Pleural effusion
- D. Pneumothorax
Correct answer: A
Rationale: The correct answer is A, Pulmonary edema. Pulmonary edema is a condition where fluid accumulates in the air sacs of the lungs, causing breathing difficulty. Pleurisy (choice B) is inflammation of the pleura causing chest pain. Pleural effusion (choice C) is the buildup of excess fluid in the pleural space, the area between the layers of tissue that line the lungs and chest cavity. Pneumothorax (choice D) is the presence of air in the pleural space, which can cause a lung to collapse.
4. 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: The correct answer is Thoracentesis. Thoracentesis is a procedure specifically designed to remove excess fluid or air from the pleural space in the chest. This process helps to relieve pressure on the lungs and improve breathing. Bronchoscopy (Choice B) is a procedure used to visualize the airways and diagnose lung conditions, not to remove fluid from the pleural space. Chest X-ray (Choice C) is an imaging test that provides a picture of the structures inside the chest, including the lungs, heart, and bones. Arterial blood gas (ABG) test (Choice D) is a blood test that measures the levels of oxygen and carbon dioxide in the blood, providing information about how well the lungs are working, but it does not involve removing excess fluid or air from the pleural space.
5. The client is on dobutamine. Adverse effects of Dobutrex (dobutamine) include the following: Select all that apply.
- A. Heart failure
- B. Bradycardia
- C. Tachycardia
- D. Respiratory distress
Correct answer: C
Rationale: The correct answer is C: Tachycardia. Dobutamine is a medication that primarily increases heart rate (tachycardia) and blood pressure. Therefore, the adverse effects of dobutamine include tachycardia. Choices A, B, and D are incorrect. Heart failure is not an adverse effect of dobutamine; in fact, it is used to treat heart failure by increasing heart contractility. Bradycardia (slow heart rate) is not an expected adverse effect of dobutamine, as it usually increases heart rate. Respiratory distress is not a common adverse effect of dobutamine.
