- A. Saphenous vein
- B. Basilic vein
- C. Radial artery
- D. Gastroepiploic artery
Correct Answer: A
Rationale: The saphenous vein in the leg is the vessel most often used for grafting in coronary artery bypass. The basilic vein in the arm, radial artery in the arm, and gastroepiploic artery from the stomach are alternative graft vessels.

The client presents to the Emergency Department with blunt trauma causing bruising and bleeding of the heart. The nurse knows that which of the following may help stop the bleeding?
- A. Embolectomy
- B. Pericardiocentesis
- C. Thoracentesis
- D. Inactivity and pressure from blood in the pericardium
Correct Answer: D
Rationale: The inactivity and increased pressure from blood in the pericardium may stop the bleeding. The client may need to have the blood aspirated from the pericardial sac, in which case pericardiocentesis is performed. One aspiration is sufficient in most cases, but if bleeding continues, open thoracotomy is indicated to control blood loss. Procedures to stop the bleeding caused by heart trauma do not include embolectomy or thoracentesis. Pericarditis is inflammation of the pericardium.
The nurse is answering questions that the client and family have about the upcoming cardiovascular surgery the client is having. What expected outcome would be best for a nursing diagnosis of Knowledge Deficiency related to unfamiliarity with diagnostic tests, preoperative preparations, and postoperative care?
- A. Client and family will understand the purpose, preparation, and aftercare of tests and surgery.
- B. Provide verbal and written information concerning the surgical procedure and aftercare.
- C. Ask the client or family member to explain the surgical procedure before signing the consent form.
- D. Clarify misconceptions concerning surgery.
Correct Answer: A
Rationale: Client and family will understand the purpose, preparation, and aftercare of tests and surgery is an outcome statement that would be appropriate for the diagnostic statement. The other statements are all interventions that are associated with the diagnostic statement.
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.
The nurse listens to the lung sounds of a postoperative client and determines that the client is not able to clear the secretions from the lungs. What intervention should the nurse provide prior to suctioning?
- A. Hyperoxygenate the client with $100% oxygen.
- B. Place the client in the supine position.
- C. Plan to suction for at least 20 seconds to remove secretions.
- D. Administer a sedative prior to suctioning.
Correct Answer: A
Rationale: Hyperoxygenate with $100% oxygen before suctioning; do not suction for more than 10 to 15 seconds. Suctioning removes oxygen and can cause hypoxemia, myocardial ischemia, and dysrhythmias. Hyperoxygenation saturates the blood and hemoglobin to compensate for temporary removal during suctioning. Elevate the head of the bed; don't place the client in the supine position. Administering a sedative may cause respiratory depression and should be avoided prior to suctioning so the cough reflex will not be depressed.
The client is being prepared for cardiothoracic surgery and is very apprehensive. What medication can be administered with a physician's prescription to decrease the amount of anesthetic that the client will receive in surgery?
- A. An antipsychotic drug
- B. An anxiolytic drug
- C. An anticholinergic drug
- D. An analgesic
Correct Answer: B
Rationale: Anxiolytics may be used before surgery to lessen anxiety and sedate the client. Clients who are relaxed and sedated when anesthesia is given require a smaller dose of anesthetic. An antipsychotic would not be indicated for this client. An anticholinergic medication may be given to decrease the amount of secretions the client will have during surgery but will not decrease anxiety. An analgesic is normally given postoperatively for pain control.
