Cardiovascular System Exam Questions
1. What is the amount of tension the ventricle must develop during contraction to eject blood from the left ventricle into the aorta?
- A. Afterload
- B. Preload
- C. Automaticity
- D. Ejection fraction
Correct answer: A
Rationale: Afterload is the correct answer because it refers to the pressure or tension that the ventricle must overcome during systole to eject blood into the aorta. Preload, on the other hand, is the degree of stretch of the ventricular muscle at the end of diastole before it contracts. Automaticity is the ability of the heart to generate electrical impulses independently, and ejection fraction is the percentage of blood pumped out of the ventricle with each heartbeat. Therefore, in the context of the question, afterload best describes the amount of tension the ventricle must develop to eject blood into the aorta.
2. A client has a disposable three-chamber chest tube in place. Which of the following findings should indicate to the nurse that the client is experiencing a complication?
- A. Continuous bubbling in the water-seal chamber
- B. Occasional bubbling in the water-seal chamber
- C. Constant bubbling in the suction-control chamber
- D. Fluctuations in the fluid level in the water-seal chamber
Correct answer: Continuous bubbling in the water-seal chamber
Rationale: Continuous bubbling in the water-seal chamber indicates air is leaking into the pleural space, which is a complication. The water-seal chamber should have intermittent bubbling during normal functioning. Occasional bubbling in the water-seal chamber is normal and shows the system is working as intended. Constant bubbling in the suction-control chamber suggests an issue with the suction control. Fluctuations in the fluid level in the water-seal chamber are an expected finding.
3. A healthcare provider is providing education to the family of a client who has been diagnosed with bipolar disorder. Which of the following instructions should the healthcare provider include?
- A. The client should avoid all stressful situations.
- B. Encourage the client to get plenty of rest.
- C. Make sure the client takes prescribed medications regularly.
- D. Provide the client with information about support groups.
Correct answer: C
Rationale: The correct answer is C: 'Make sure the client takes prescribed medications regularly.' Consistent medication adherence is crucial in managing the symptoms and stabilizing mood in individuals with bipolar disorder. Choice A is incorrect because avoiding all stressful situations is often not feasible and not the primary treatment approach for bipolar disorder. Choice B, while important, is not as critical as ensuring medication compliance. Choice D is helpful but not as essential as medication adherence for the treatment of bipolar disorder.
4. The physician orders a Salem sump tube for gastrointestinal intubation. The nurse prepares for the insertion and obtains which of the following items from the supply room?
- A. A tube with a single lumen that connects to suction
- B. A tube with a large lumen and an air vent
- C. A Sengstaken-Blakemore tube
- D. A Dobbhoff weighted tube
Correct answer: B
Rationale: A tube with a large lumen and an air vent is a Salem sump tube. A tube with a single lumen is called a Levin’s tube. A Sengstaken-Blakemore tube is used to control bleeding in the esophagus. A Dobbhoff weighted tube is used for feedings.
5. After working at your job for 10 months and feeling unable to tolerate the tension and stress between staff nurses and the laissez-faire nurse manager who is not a leader, what is the best course of action?
- A. Submit a resignation and leave within 30 days.
- B. Complain to staff about the nurse manager.
- C. Seek another position within the healthcare organization and apply for a transfer.
- D. Inform the chief nursing officer that you are leaving and explain your dissatisfaction with the lack of leadership.
Correct answer: C
Rationale: In this situation, it is best to seek another position within the healthcare organization and apply for a transfer. Making professional decisions should involve careful evaluation and consideration. It is important to align personal values with the organizational culture. By seeking advice from a mentor or counselor, you can gain valuable insights and consider different perspectives. Resigning abruptly, complaining to staff, or informing the chief nursing officer without exploring other options may not be the most effective or professional approach in this scenario.
