Cardiovascular System Exam
1. What is the buildup of plaque in the arteries that can lead to heart attack, stroke, and other cardiovascular diseases?
- A. Atherosclerosis
- B. Arteriosclerosis
- C. Hypertension
- D. Diabetes
Correct answer: A
Rationale: Atherosclerosis is the correct answer. It is the buildup of plaque in the arteries, leading to the narrowing of blood vessels, reduced blood flow, and an increased risk of heart attacks, strokes, and other cardiovascular diseases. Arteriosclerosis (choice B) refers to the hardening and thickening of arterial walls, while hypertension (choice C) is high blood pressure, and diabetes (choice D) is a metabolic disorder characterized by high blood sugar levels. Therefore, choices B, C, and D are incorrect in the context of the question.
2. The client asks about side effects of taking digoxin. How does the nurse respond?
- A. Anorexia can be a side effect of digoxin.
- B. Tachycardia can be a side effect of digoxin.
- C. Constipation can be a side effect of digoxin.
- D. Urinary retention can be a side effect of digoxin.
Correct answer: A
Rationale: The correct answer is A: 'Anorexia can be a side effect of digoxin.' Anorexia, nausea, vomiting, and diarrhea are commonly known side effects of digoxin. Choice B, 'Tachycardia can be a side effect of digoxin,' is incorrect as digoxin is used to treat tachycardia, not cause it. Choice C, 'Constipation can be a side effect of digoxin,' is incorrect as constipation is not a typical side effect of digoxin. Choice D, 'Urinary retention can be a side effect of digoxin,' is also incorrect as urinary retention is not a common side effect associated with digoxin use.
3. The client on enoxaparin (Lovenox) is scheduled for surgery. What is the nurse’s priority action?
- A. Hold the enoxaparin and notify the healthcare provider.
- B. Administer the enoxaparin as scheduled.
- C. Administer vitamin K before the surgery.
- D. Monitor the client’s INR and proceed with surgery.
Correct answer: A
Rationale: The correct answer is A: Hold the enoxaparin and notify the healthcare provider. Enoxaparin, being an anticoagulant, should be held before surgery to reduce the risk of excessive bleeding during the procedure. It is crucial to inform the healthcare provider to determine the appropriate management plan. Choice B is incorrect because administering enoxaparin before surgery can increase the risk of bleeding. Choice C is incorrect as vitamin K administration is not typically indicated in this situation. Choice D is incorrect because monitoring the client's INR and proceeding with surgery without addressing the enoxaparin can lead to significant bleeding complications.
4. What is a severe and often sudden allergic reaction that can lead to breathing difficulties and anaphylactic shock?
- A. Anaphylaxis
- B. Allergic rhinitis
- C. Bronchospasm
- D. Asthma attack
Correct answer: A
Rationale: Anaphylaxis is the correct answer. It is a severe allergic reaction that can result in difficulty breathing, a drop in blood pressure, and even anaphylactic shock if not treated promptly. Choice B, allergic rhinitis, is characterized by symptoms such as a runny or stuffy nose, sneezing, and itching. Choice C, bronchospasm, refers to the sudden constriction of the muscles in the walls of the bronchioles, leading to breathing difficulties. Choice D, asthma attack, involves the inflammation and narrowing of the airways, resulting in symptoms like wheezing, coughing, and chest tightness.
5. This test measures the amount of blood the heart pumps with each beat, often used to assess heart function.
- A. Ejection fraction
- B. Cardiac output
- C. Stroke volume
- D. End-diastolic volume
Correct answer: A
Rationale: The correct answer is A: Ejection fraction. Ejection fraction is a measure of the percentage of blood that is pumped out of the left ventricle with each beat, used to assess heart function. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is not specific to each beat. Choice C, Stroke volume, is the amount of blood ejected by the heart in one contraction but does not specify the percentage of blood pumped out. Choice D, End-diastolic volume, is the volume of blood in the ventricle just before it contracts and does not directly measure the blood pumped with each beat.
