Cardiovascular System Exam Questions Pdf
1. The nurse is caring for a client on digoxin. What is the most important assessment before administering this medication?
- A. Check the client’s heart rate.
- B. Check the client’s blood pressure.
- C. Check the client’s respiratory rate.
- D. Check the client’s oxygen saturation.
Correct answer: A
Rationale: The correct answer is to check the client’s heart rate before administering digoxin because one of the side effects of digoxin is bradycardia. Monitoring the heart rate is crucial to assess whether the client's heart rate is within the acceptable range before giving the medication. Checking the blood pressure (Choice B), respiratory rate (Choice C), or oxygen saturation (Choice D) are important assessments in general patient care, but they are not specifically related to the administration of digoxin.
2. What is the term used to describe a condition where the blood flow to the brain is temporarily interrupted, often referred to as a 'mini-stroke'?
- A. Transient ischemic attack (TIA)
- B. Stroke
- C. Myocardial infarction
- D. Pulmonary embolism
Correct answer: A
Rationale: The correct answer is A: Transient ischemic attack (TIA). A transient ischemic attack (TIA) is often called a 'mini-stroke' because it is characterized by a temporary interruption of blood flow to the brain, resulting in stroke-like symptoms that typically resolve within a short period. Choice B, 'Stroke,' is incorrect because a stroke involves a more prolonged interruption of blood flow, leading to lasting brain damage. Choices C and D, 'Myocardial infarction' and 'Pulmonary embolism,' are unrelated conditions involving the heart and lungs, respectively, and do not describe a temporary interruption of blood flow to the brain.
3. 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.
4. Which test measures how well the lungs work by assessing the amount of air the lungs can hold and how quickly air can be exhaled?
- A. Spirometry
- B. Pulse oximetry
- C. Arterial blood gas (ABG)
- D. Chest X-ray
Correct answer: A
Rationale: The correct answer is A, Spirometry. Spirometry is a pulmonary function test that evaluates lung function by measuring the amount of air a person can exhale and how quickly, assisting in the diagnosis of conditions such as asthma and COPD. Choices B, C, and D are incorrect because Pulse oximetry measures oxygen saturation in the blood, Arterial blood gas (ABG) evaluates blood pH, oxygen, and carbon dioxide levels, and a Chest X-ray provides an image of the lungs but does not measure lung function.
5. The client is receiving intravenous dopamine. What is the most important nursing assessment?
- A. Monitor heart rate and rhythm
- B. Monitor blood pressure
- C. Monitor respiratory rate
- D. Monitor oxygen saturation
Correct answer: A
Rationale: The correct answer is to monitor heart rate and rhythm when a client is receiving intravenous dopamine. Dopamine is known to potentially cause arrhythmias, making this assessment crucial. While monitoring blood pressure, respiratory rate, and oxygen saturation are important nursing assessments, they are not the most critical when dopamine is being administered.
