Cardiovascular System Exam
1. What is the term for inflammation of the bronchial tubes, often leading to a persistent cough and mucus production?
- A. Bronchitis
- B. Asthma
- C. Pneumonia
- D. Cystic fibrosis
Correct answer: A
Rationale: The correct answer is 'Bronchitis.' Bronchitis refers to the inflammation of the bronchial tubes, which can be acute or chronic, leading to symptoms like coughing and increased mucus production. Choice B, 'Asthma,' is a chronic condition characterized by inflammation and narrowing of the airways, often causing wheezing and shortness of breath. Choice C, 'Pneumonia,' is an infection that inflames air sacs in one or both lungs, leading to symptoms like fever, cough, and difficulty breathing. Choice D, 'Cystic fibrosis,' is a genetic disorder that affects the lungs and digestive system, causing mucus buildup and respiratory issues.
2. The client has a prescription for sublingual nitroglycerin. What is the nurse's instruction for how to take this medication during an episode of chest pain?
- A. Take one tablet every 5 minutes, up to three tablets.
- B. Take one tablet every hour until the pain subsides.
- C. Take two tablets immediately if chest pain occurs.
- D. Take one tablet with a full glass of water.
Correct answer: A
Rationale: The correct answer is A. The standard instruction for sublingual nitroglycerin during an episode of chest pain is to take one tablet every 5 minutes, up to three tablets. If the pain persists after taking three tablets, the client should seek emergency help. Choice B is incorrect because taking one tablet every hour is not the appropriate dosing for acute chest pain. Choice C is incorrect as taking two tablets immediately is not in line with the recommended dosing instructions. Choice D is incorrect because sublingual nitroglycerin should be placed under the tongue, not swallowed with water.
3. The client on warfarin has an INR of 3.8. What is the most appropriate action by the nurse?
- A. Administer vitamin K.
- B. Hold the next dose of warfarin.
- C. Increase the dose of warfarin.
- D. Notify the healthcare provider immediately.
Correct answer: A
Rationale: An INR of 3.8 is elevated, indicating an increased risk of bleeding. Administering vitamin K can help reverse the effects of warfarin. Holding the next dose of warfarin would be appropriate if the INR was too high, but not as the first-line action. Increasing the dose of warfarin would worsen the situation by further increasing the INR. Notifying the healthcare provider is important, but immediate action to address the elevated INR is necessary.
4. The client on furosemide (Lasix) is at risk for which electrolyte imbalance?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hyponatremia
- D. Hypernatremia
Correct answer: B
Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. This electrolyte imbalance is a significant risk associated with diuretic use. Choices A, C, and D are incorrect. Hyperkalemia (choice A) is not typically associated with furosemide use. Hyponatremia (choice C) and hypernatremia (choice D) are related to sodium levels, not potassium levels affected by furosemide.
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.
