Chapter 29 : Caring for Clients Undergoing Cardiovascular Surgery Questions
Question 1 of 5
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?
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.
Question 2 of 5
The nurse is caring for a client postoperatively after undergoing a coronary artery bypass graft. What intervention can the nurse provide to reduce the risk of the development of wound dehiscence?
Correct Answer: D
Rationale: Instruct the client to press a pillow against the chest when deep breathing, coughing, and performing active exercise. Splinting promotes comfort and decreases the potential for dehiscence. Encouraging oral fluids will not prevent dehiscence. Lungs should be assessed every 4 hours or more frequently according to the client's condition. Suction should only be provided as needed.
Question 3 of 5
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?
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.
Question 4 of 5
The nurse is caring for a client who is having a mitral valve replacement with a mechanical valve. What instructions should the nurse be sure the client understands prior to being discharged?
Correct Answer: B
Rationale: A mechanical valve should last at least 20 years. The disadvantages are the risk for thrombi and emboli, so anticoagulation is necessary. There is a risk of bleeding, and there can be a sudden malfunction in the valve. An allograft will last 10 to 15 years. A bioprosthetic valve does not require anticoagulation but is prone to deterioration and calcification.
Question 5 of 5
A client is at the clinic for follow-up after cardiothoracic surgery and tells the nurse, 'I don't know what is wrong with me. I don't want to eat, and I feel depressed.' What is the best response by the nurse to this statement?
Correct Answer: C
Rationale: Discharge instruction should be given prior to the client leaving the hospital about it taking several weeks for a normal appetite to return and that depression is normal and temporary. The client does not need psychiatric help at this point but may benefit from a support group with other clients that have had cardiothoracic surgery. Telling a client there is no reason for being depressed is nontherapeutic and demeans the client's feelings. Telling the client to inform the physician because the depression could be serious could cause alarm.
