Cardiovascular System Exam Questions Pdf
1. What is a chronic condition where the blood pressure in the arteries is persistently elevated, increasing the risk of heart disease and stroke?
- A. Hypertension
- B. Hypotension
- C. Hyperlipidemia
- D. Hyperglycemia
Correct answer: A
Rationale: Hypertension, also known as high blood pressure, is a chronic condition characterized by persistently elevated pressure in the arteries. This condition increases the risk of heart disease, stroke, and other health issues. Hypotension (choice B) refers to low blood pressure and is not the correct answer. Hyperlipidemia (choice C) is high levels of fats in the blood, not related to blood pressure. Hyperglycemia (choice D) is high blood sugar levels, not directly related to elevated blood pressure.
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. The nurse is administering nitroglycerin IV to a client with chest pain. What is the most important parameter to monitor?
- A. Blood pressure
- B. Heart rate
- C. Oxygen saturation
- D. Respiratory rate
Correct answer: A
Rationale: The correct answer is A: Blood pressure. When administering nitroglycerin IV to a client with chest pain, monitoring blood pressure is crucial as nitroglycerin can cause significant hypotension. While heart rate, oxygen saturation, and respiratory rate are important parameters to assess, blood pressure takes precedence in this scenario due to the potential hypotensive effects of nitroglycerin.
4. What is a condition where the airways become swollen and produce extra mucus, making it difficult to breathe, often associated with COPD?
- A. Chronic bronchitis
- B. Pneumonia
- C. Emphysema
- D. Tuberculosis
Correct answer: A
Rationale: Chronic bronchitis is the correct answer. It is a long-term inflammation of the bronchi, leading to persistent cough and mucus production, commonly associated with chronic obstructive pulmonary disease (COPD). Pneumonia (Choice B) is an infection that inflames the air sacs in one or both lungs. Emphysema (Choice C) is a lung condition where the air sacs in the lungs are damaged, making it difficult to breathe. Tuberculosis (Choice D) is a bacterial infection that primarily affects the lungs.
5. A client on a beta blocker has a blood pressure of 90/60 mm Hg. What is the nurse’s priority action?
- A. Hold the beta blocker and notify the healthcare provider.
- B. Administer the beta blocker as ordered.
- C. Administer a diuretic to reduce blood pressure.
- D. Continue to monitor the client and reassess in 30 minutes.
Correct answer: A
Rationale: The correct answer is to hold the beta blocker and notify the healthcare provider. A blood pressure of 90/60 mm Hg is already low, and beta blockers can further decrease blood pressure. Administering the beta blocker can potentially worsen the situation, leading to complications. Administering a diuretic or continuing to monitor the client without taking immediate action could delay necessary intervention. Therefore, holding the beta blocker and involving the healthcare provider promptly is crucial in this scenario.
