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 a blood clot that forms in a vein, often in the legs, and can cause serious complications if it travels to the lungs?
- A. Deep vein thrombosis (DVT)
- B. Pulmonary embolism
- C. Varicose veins
- D. Atherosclerosis
Correct answer: A
Rationale: The correct answer is Deep vein thrombosis (DVT). DVT is a blood clot that forms in a deep vein, typically in the legs, and can lead to serious complications if it breaks loose and travels to the lungs, causing a pulmonary embolism. Varicose veins (choice C) are enlarged, twisted veins usually found in the legs but are not related to blood clots. Atherosclerosis (choice D) is a condition where arteries become narrowed and hardened due to a buildup of plaque, not directly related to blood clots.
3. The client on a beta blocker has a blood pressure of 88/58 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. Increase the dose of the beta blocker.
- D. Continue to monitor the client and reassess in 30 minutes.
Correct answer: A
Rationale: The correct action for the nurse to take when a client on a beta blocker presents with a blood pressure of 88/58 mm Hg is to hold the beta blocker and notify the healthcare provider. Beta blockers can further decrease blood pressure, which is already low in this case. Administering the beta blocker as ordered (Choice B) would exacerbate the hypotension. Increasing the dose of the beta blocker (Choice C) would be inappropriate and unsafe given the low blood pressure. Continuing to monitor the client and reassessing in 30 minutes (Choice D) could lead to a delay in necessary intervention. Therefore, the priority is to hold the medication and seek guidance from the healthcare provider.
4. The healthcare provider is monitoring a client receiving lidocaine IV. What side effect is the healthcare provider most concerned about?
- A. Severe headache
- B. Nausea and vomiting
- C. Seizures
- D. Tremors
Correct answer: C
Rationale: Seizures are the most concerning side effect of lidocaine IV administration due to its potential to indicate lidocaine toxicity, which can lead to serious complications such as cardiovascular collapse. Headache, nausea, and tremors are not typically associated with lidocaine IV and are less concerning compared to seizures in this context.
5. The nurse is teaching a client about the side effects of beta blockers. What is the most important side effect to monitor?
- A. Hypotension
- B. Bradycardia
- C. Hyperkalemia
- D. Tachycardia
Correct answer: A
Rationale: The most important side effect to monitor when a client is on beta blockers is hypotension. Beta blockers can cause a significant drop in blood pressure, especially at the initiation of therapy. Monitoring for hypotension is crucial to prevent complications such as dizziness, syncope, or falls. While bradycardia can also occur with beta blockers, hypotension takes precedence due to its immediate impact on perfusion. Hyperkalemia is not a common side effect of beta blockers. Tachycardia is actually a condition that beta blockers aim to treat, so it is not a side effect to monitor.
