The pathophysiology instructor is discussing heart disease with a class of prenursing students. One of the students asks what indications there are for coronary artery bypass surgery. What would be an acceptable answer(s) from the instructor? Select all that apply.
- A. Atheromas are calcified and noncompressible.
- B. The heart cannot be repaired without compromising oxygenation of the body.
- C. The client has multiple coronary artery occlusions.
- D. Transluminal coronary angioplasty is necessary.
- E. The Anatomic location of the occlusion(s) interferes with the safe insertion of a coronary artery catheter.
Correct Answer: A,B,E
Rationale: A coronary artery bypass is performed when (1) the client has multiple coronary artery occlusions, (2) the atheromas are calcified and noncompressible, or (3) the anatomic location of the occlusion(s) interferes with the safe insertion of a coronary artery catheter. This makes the other options incorrect.
After being discharged from the hospital after undergoing cardiothoracic surgery, the client asks the nurse when it will be possible to resume sexual activity. What is the best response by the nurse?
- A. I can't believe you are worried about that so soon after your surgery.
- B. You won't be able to resume sexual activity until your 6-month checkup with the surgeon.
- C. In about 2 to 4 weeks if you are able to climb stairs without difficulty breathing or chest pain.
- D. You may have a difficult time resuming sexual activities after this surgery.
Correct Answer: C
Rationale: Sexual relations usually can be resumed in 2 to 4 weeks after cardiothoracic surgery depending on one's comfort level and tolerance for activity; climbing two flights of stairs without dyspnea or chest pain is a common guideline. The other options are nontherapeutic responses to the client's concern. Six months is an excessively long time period to wait if the client has been able to resume activities without shortness of breath or chest pain.
The nurse reinforces teaching for a client who is scheduled for coronary artery bypass surgery. The client asks, 'What vessels can be used if my saphenous vein doesn't meet the requirements?' Which vessel(s) should the nurse include in the response to the client? Select all that apply.
- A. The basilic vein
- B. The axillary vein
- C. The popliteal vein
- D. The gastroepiploic artery
- E. The internal thoracic artery
Correct Answer: A,D,E
Rationale: Alternative graft vessels include the following: the internal mammary and internal thoracic arteries in the chest; the basilic and cephalic veins in the arm, the radial artery in the arm, and the gastroepiploic artery from the stomach, in some cases. The axillary and popliteal veins are not alternative graft vessels; therefore, the nurse should not include them in the response to the client.
A client is diagnosed with obstructive atherosclerotic plaque of the left carotid artery. What procedure does the nurse anticipate preparing the client for?
- A. Endarterectomy
- B. Thrombectomy
- C. Embolectomy
- D. Coronary artery bypass graft
Correct Answer: A
Rationale: Endarterectomy is the resection and removal of the lining of an artery. This type of surgery is performed to remove obstructive atherosclerotic plaques from the aorta, carotid, femoral, or popliteal arteries. A thrombectomy is used to remove a thrombus for a vessel. An embolectomy is the removal of an embolus. Coronary artery bypass grafting is not indicated for the removal of an atherosclerotic plaque.
A client was driving a car without wearing a seat belt and slid off the road and hit a tree. The client's chest was crushed against a steering wheel. What type of lethal injury does the nurse anticipate the client may have suffered?
- A. Cardiac tamponade
- B. A pleural effusion
- C. Bladder trauma
- D. Fractured pelvis
Correct Answer: A
Rationale: A nonpenetrating injury of the chest, such as being crushed against a steering wheel, may cause bruising and bleeding of the heart. Because the pericardium encloses the heart, blood accumulates in the pericardial space, resulting in cardiac tamponade. Although a fractured pelvis and bladder trauma may be sustained, they are generally not lethal. A pleural effusion would not result from this traumatic injury.
