Nokea
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.

The nurse is preparing a client for coronary artery bypass surgery. What vessel does the nurse know is most commonly used for grafting?
- 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 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 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.
A client recently had a myocardial infarction (MI) and asks the nurse if he will require a heart transplant. Based on the nurse's knowledge of indications for heart transplant, what is the best response?
- A. No. Heart transplant is indicated for cardiomyopathy, end-stage coronary artery disease, and end-stage heart failure.
- B. No. Heart transplant is only indicated for congenital heart defects.
- C. Yes. You may require a heart transplant if you have another heart attack.
- D. Yes. Your heart will not function as well as it did before the heart attack, and a new heart will give you the best chance for survival.
Correct Answer: A
Rationale: In adults, heart transplantation is indicated for cardiomyopathy, end-stage coronary artery disease, and end-stage heart failure. In newborns and infants, heart transplantation is indicated for a severe congenital cardiac defect. It is performed only when other treatment modalities fail or are unavailable. It is not used to treat clients after an MI unless they meet any of the given criteria.
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.
