Chapter 29 Questions
Question 1 of 5
The nursing instructor is giving a class on assessing cardiac clients after thoracic surgery. What assessment is most important for the nurse to perform when caring for this client?
Correct Answer: D
Rationale: The nurse assesses the blood pressure (BP) and pulse rate in both arms after thoracic surgery. Although it is necessary for the nurse to also assess pulmonary artery pressure, temperature, skin, and mentation after thoracic surgery, blood pressure and pulse rate are the most essential assessments.
Question 2 of 5
When discussing the nursing process, the instructor stresses that for clients undergoing cardiac surgery, it is important for the nurse to demonstrate competence. What is the rationale for this statement?
Correct Answer: C
Rationale: When the nurse is knowledgeable and competent, it relieves the client's insecurity and anxiety regarding the surgery.
Question 3 of 5
A nurse caring for a client who has had cardiac or vascular surgery knows to do hourly assessments on which of the following?
Correct Answer: B
Rationale: While assessing a client undergoing cardiac or vascular surgery, the nurse assesses the client's fluid intake and urine output on an hourly basis. The nurse may assess the blood sugar level during the initial assessment process but not hourly. For a client undergoing a cardiac or vascular surgery, the nurse does not assess for mentation. Arterial blood gases would not be assessed hourly.
Question 4 of 5
The nurse is caring for an older adult client who is deciding whether to have cardiovascular surgery. The client asks the nurse why the risks are greater for them than for a younger person. What would be the nurse's answer?
Correct Answer: A
Rationale: Many older adults have comorbidities such as diabetes, heart failure, cardiac dysrhythmias, hypertension, and poor renal function, necessitating careful consideration regarding the potential risks and benefits of cardiovascular surgery. These clients require close observation during the postoperative period. The other options are incorrect.
Question 5 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.
