Cardiovascular System Exam
1. Which condition is characterized by chest pain due to reduced blood flow to the heart muscle?
- A. Angina
- B. Myocardial infarction
- C. Pericarditis
- D. Arrhythmia
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.
2. What test measures the pressure inside the arteries as the heart pumps blood?
- A. Blood pressure test
- B. Pulse oximetry
- C. Echocardiogram
- D. Spirometry
Correct answer: A
Rationale: The correct answer is A) Blood pressure test. A blood pressure test is specifically designed to measure the pressure inside the arteries as the heart pumps blood. This test is crucial in providing information about cardiovascular health by determining the force of blood against the artery walls. Choice B, Pulse oximetry, measures oxygen saturation in the blood, not blood pressure. Choice C, Echocardiogram, is an ultrasound test that evaluates the structure and function of the heart, not specifically blood pressure. Choice D, Spirometry, is a test used to assess lung function, not blood pressure.
3. What test measures the pressure in the arteries during the contraction and relaxation of the heart?
- A. Blood pressure test
- B. Electrocardiogram (ECG or EKG)
- C. Spirometry
- D. Pulse oximetry
Correct answer: A
Rationale: The correct answer is 'Blood pressure test.' This test measures the pressure in the arteries during the contraction (systolic) and relaxation (diastolic) phases of the heart, providing important information about heart health. Choice B, 'Electrocardiogram (ECG or EKG),' records the heart's electrical activity and is not specifically related to measuring arterial pressure. Choice C, 'Spirometry,' assesses lung function by measuring airflow. Choice D, 'Pulse oximetry,' measures oxygen saturation in the blood, not arterial pressure.
4. What is a chronic condition where the heart is unable to pump blood efficiently, leading to fluid buildup in the lungs and other parts of the body?
- A. Heart failure
- B. Cardiomyopathy
- C. Pericarditis
- D. Aortic stenosis
Correct answer: A
Rationale: Heart failure is the correct answer. It is a chronic condition characterized by the heart's inability to pump blood efficiently, resulting in symptoms like fluid buildup in the lungs and other parts of the body, shortness of breath, fatigue, and fluid retention. Cardiomyopathy (choice B) refers to diseases of the heart muscle, but it is a broader category that includes various conditions affecting the heart muscle. Pericarditis (choice C) is the inflammation of the pericardium, the sac surrounding the heart, and aortic stenosis (choice D) is a condition where the aortic valve narrows, restricting blood flow from the heart.
5. The client on furosemide is at risk for which electrolyte imbalance?
- A. Hypokalemia
- B. Hypernatremia
- C. Hyperkalemia
- D. Hyponatremia
Correct answer: A
Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. This electrolyte imbalance is a significant risk associated with the use of diuretics. Choice B, Hypernatremia, is incorrect as furosemide is not known to cause high sodium levels. Choice C, Hyperkalemia, is also incorrect as furosemide tends to cause potassium depletion rather than excess. Choice D, Hyponatremia, is not directly related to furosemide use.
