Chapter 29 : Caring for Clients Undergoing Cardiovascular Surgery Questions
Question 1 of 5
A client has been admitted for a commissurotomy. The nurse knows that a commissurotomy repairs which of the following?
Correct Answer: B
Rationale: Heart valves need surgical repair or replacement if they become narrowed (stenosed) or stretched (incompetent). One method of repair is commissurotomy (opening adhesions in the valve cusps), which is done without direct visualization of the valve.
Question 2 of 5
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?
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.
Question 3 of 5
A nurse caring for a client who has had cardiac surgery must understand how pulmonary artery pressure is monitored. What is important about pulmonary artery pressure?
Correct Answer: B
Rationale: Pulmonary artery pressure monitoring aids in the early treatment of fluid imbalances, prevents left-sided congestive heart failure or promotes its early correction, and helps monitor the client's response to treatment. The other options are incorrect. The measurement of pulmonary artery pressure does not assess right-sided heart pressures or left atrial pressure.
Question 4 of 5
A client has experienced a myocardial infarction (MI). After the acute stage of the MI, what is the most lethal complication the nurse should be aware can occur?
Correct Answer: B
Rationale: A ventricular aneurysm is the most lethal complication among clients who survive the acute stage of a myocardial infarction (MI). Thrombophlebitis is a complication of immobility. Mitral valve prolapse is an acquired disorder that is not a complication from having an MI. Cardiogenic shock, not septic shock, is a complication after sustaining an MI.
Question 5 of 5
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?
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.
