Cardiovascular System Exam Questions Pdf
1. Which of the following is a chronic condition characterized by difficulty breathing due to airflow obstruction, commonly associated with long-term smoking?
- A. Chronic obstructive pulmonary disease (COPD)
- B. Asthma
- C. Pulmonary hypertension
- D. Bronchitis
Correct answer: A
Rationale: The correct answer is A, Chronic obstructive pulmonary disease (COPD). COPD is a chronic lung condition characterized by persistent airflow obstruction, commonly linked to long-term smoking. Choice B, Asthma, is a chronic condition characterized by reversible airflow obstruction and airway inflammation triggered by various factors like allergens and irritants. Choice C, Pulmonary hypertension, is a condition characterized by high blood pressure in the arteries of the lungs. Choice D, Bronchitis, is an inflammation of the bronchial tubes that may be acute or chronic, but it is not typically associated with long-term smoking like COPD.
2. The client on warfarin has an INR of 1.2. What is the nurse’s priority action?
- A. Increase the dose of warfarin
- B. Administer vitamin K
- C. Monitor for signs of bleeding
- D. Hold the next dose and notify the healthcare provider
Correct answer: A
Rationale: The correct answer is to increase the dose of warfarin. An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating that the dose is subtherapeutic. The priority action in this situation is to adjust the dose to achieve the target therapeutic INR range (usually 2-3) to prevent thromboembolic events. Administering vitamin K is not necessary as the INR is low, and there are no signs of bleeding. Monitoring for signs of bleeding is important but not the priority in this case since the INR is subtherapeutic. Holding the next dose and notifying the healthcare provider would delay the intervention needed to adjust the dose and achieve the therapeutic range.
3. Which condition involves the body's immune system attacking the lungs and kidneys, causing severe respiratory and renal damage?
- A. Goodpasture syndrome
- B. Sarcoidosis
- C. Wegener's granulomatosis
- D. Interstitial lung disease
Correct answer: A
Rationale: Goodpasture syndrome is the correct answer. It is an autoimmune disease characterized by the immune system attacking the lungs and kidneys, leading to bleeding in the lungs and kidney failure. Sarcoidosis primarily affects the lungs and lymph nodes, not the kidneys. Wegener's granulomatosis affects the lungs, sinuses, and kidneys, but it is characterized by inflammation of blood vessels. Interstitial lung disease involves scarring of the lung tissue, not direct immune system attacks on the lungs and kidneys.
4. The client on nitroglycerin complains of a headache. What is the most appropriate response by the nurse?
- A. Administer acetaminophen as prescribed for the headache.
- B. Hold the next dose of nitroglycerin.
- C. Discontinue the nitroglycerin immediately.
- D. Notify the healthcare provider immediately.
Correct answer: A
Rationale: The correct response is to administer acetaminophen as prescribed for the headache. Headaches are a common side effect of nitroglycerin due to vasodilation. Administering acetaminophen can help relieve the headache. Holding the next dose of nitroglycerin (Choice B) may not address the current headache, and discontinuing nitroglycerin immediately (Choice C) without healthcare provider guidance can be dangerous due to the potential for rebound hypertension. Notifying the healthcare provider immediately (Choice D) is not necessary for a common side effect like a headache, and the nurse can manage this symptom independently.
5. Which type of heart disease involves the stiffening of the heart muscle, reducing its ability to relax and fill with blood?
- A. Restrictive cardiomyopathy
- B. Hypertrophic cardiomyopathy
- C. Dilated cardiomyopathy
- D. Ventricular hypertrophy
Correct answer: A
Rationale: The correct answer is A, restrictive cardiomyopathy. This condition specifically involves the stiffening of the heart muscle, leading to a reduced ability to relax and fill with blood between beats. Choice B, hypertrophic cardiomyopathy, is characterized by abnormal thickening of the heart muscle, not stiffening. Choice C, dilated cardiomyopathy, involves the enlargement and weakening of the heart chambers, not stiffening. Choice D, ventricular hypertrophy, refers to the thickening of the walls of the heart's pumping chambers but does not specifically involve the stiffening that is characteristic of restrictive cardiomyopathy.
