Physical Exam Cardiovascular System
1. The nurse is administering digoxin to a client with a heart rate of 45 bpm. What is the nurse’s priority action?
- A. Hold the digoxin and notify the healthcare provider.
- B. Administer the digoxin as ordered.
- C. Increase the dose of digoxin.
- D. Monitor the client’s heart rate and reassess in 30 minutes.
Correct answer: A
Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A heart rate of 45 bpm is already low, and digoxin can further decrease the heart rate, leading to serious complications like bradycardia or heart block. Administering the medication can exacerbate the bradycardia, hence it should be withheld. Increasing the dose of digoxin is contraindicated due to the client's low heart rate. Monitoring the heart rate alone without taking immediate action to withhold the medication is not the priority when faced with the risk of further lowering the heart rate.
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 on amiodarone reports shortness of breath. What is the nurse’s best response?
- A. Notify the healthcare provider immediately.
- B. Reassure the client that this is a common side effect.
- C. Instruct the client to monitor their symptoms at home.
- D. Suggest the client reduce physical activity.
Correct answer: A
Rationale: When a client on amiodarone reports shortness of breath, it can be indicative of pulmonary toxicity, a severe side effect associated with this medication. The nurse's priority is to notify the healthcare provider immediately to assess the situation and determine the appropriate course of action. Choice B is incorrect because shortness of breath with amiodarone should not be dismissed as a common side effect. Instructing the client to monitor symptoms at home (Choice C) may delay necessary intervention. Suggesting the client reduce physical activity (Choice D) does not address the potential serious nature of the symptom and the need for prompt evaluation.
4. Which condition is characterized by the narrowing or blockage of arteries that supply blood to the heart by plaque?
- A. Coronary artery disease (CAD)
- B. Atherosclerosis
- C. Peripheral artery disease
- D. Congestive heart failure
Correct answer: A
Rationale: The correct answer is A, Coronary artery disease (CAD). CAD specifically refers to the condition where the arteries supplying blood to the heart become narrowed or blocked by plaque buildup. Choice B, Atherosclerosis, is a general term for the hardening and narrowing of arteries due to plaque buildup but does not specifically mention the heart. Choice C, Peripheral artery disease, involves narrowing of arteries that supply blood to areas other than the heart. Choice D, Congestive heart failure, is a condition where the heart is unable to pump blood effectively but is not primarily caused by narrowed or blocked arteries.
5. The nurse is administering a beta blocker to a client with a heart rate of 58 bpm. What is the nurse’s priority action?
- A. Administer the beta blocker as ordered.
- B. Hold the beta blocker and notify the healthcare provider.
- C. Increase the dose of the beta blocker.
- D. Monitor the client’s heart rate and reassess in 30 minutes.
Correct answer: B
Rationale: The correct answer is B. A heart rate of 58 bpm is considered low, and beta blockers can further decrease the heart rate. Therefore, the nurse's priority action should be to hold the beta blocker and notify the healthcare provider for further assessment. Choice A is incorrect because administering the beta blocker without considering the low heart rate can worsen the condition. Choice C is incorrect as increasing the dose of the beta blocker can lead to further slowing of the heart rate, which is not safe in this situation. Choice D is not the priority action; holding the medication and seeking guidance from the healthcare provider is more crucial.
