Cardiovascular System Exam Questions

Question 1 of 5

Which condition is characterized by chest pain due to reduced blood flow to the heart muscle?

Correct Answer: A

Rationale: The correct answer is A, Angina. Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle, often due to coronary artery disease. Choice B, Myocardial infarction, involves the death of heart muscle tissue due to a lack of blood supply, presenting with symptoms similar to angina but more severe. Pericarditis (Choice C) is inflammation of the pericardium, the sac surrounding the heart, which may cause chest pain but is not primarily due to reduced blood flow. Arrhythmia (Choice D) refers to abnormal heart rhythms but is not directly related to chest pain due to reduced blood flow.

Question 2 of 5

Which structure serves as the major chemoreceptor of the heart?

Correct Answer: A

Rationale: The correct answer is A, the carotid body. The carotid body is the major chemoreceptor of the heart responsible for detecting changes in blood oxygen, carbon dioxide, and pH levels. This specialized structure helps regulate the cardiovascular system's response to maintain appropriate oxygen levels in the blood. Choices B, C, and D are incorrect as they are not directly involved in chemoreception in the heart. The aortic body is primarily involved in blood pressure regulation, the vagus nerve is a cranial nerve responsible for parasympathetic innervation, and the SA node is known as the heart's natural pacemaker.

Question 3 of 5

What is an acute respiratory infection that inflames the alveoli in one or both lungs, causing them to fill with fluid or pus?

Correct Answer: A

Rationale: Pneumonia is the correct answer because it is an acute respiratory infection that inflames the alveoli in one or both lungs, leading to the accumulation of fluid or pus. This condition presents with symptoms like cough, fever, and difficulty breathing. Bronchitis is the inflammation of the bronchial tubes, not the alveoli. Tuberculosis is a bacterial infection that primarily affects the lungs but does not always result in alveolar inflammation. Asthma is a chronic respiratory condition characterized by airway inflammation and narrowing, not alveolar inflammation.

Question 4 of 5

Which condition is characterized by fluid collection in the lungs, making it difficult to breathe?

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.

Question 5 of 5

The client on atorvastatin (Lipitor) should be advised to report which of the following symptoms?

Correct Answer: A

Rationale: The correct answer is A: Muscle pain. Muscle pain can be a sign of rhabdomyolysis, a serious side effect of statins like atorvastatin. Rhabdomyolysis is a condition where muscle fibers break down rapidly and release their contents into the bloodstream, which can lead to kidney damage. Headache, nausea, and dizziness are not commonly associated with atorvastatin use and are less likely to indicate a serious adverse reaction compared to muscle pain.
