Chapter 29 : Caring for Clients Undergoing Cardiovascular Surgery Questions
Question 1 of 5
A client had a cardiac transplant 6 weeks ago. The client calls the clinic and informs the nurse he has a fever of $101^{\circ} \mathrm{F}$, chest tenderness, and flulike symptoms. What does the nurse suspect the client is experiencing?
Correct Answer: B
Rationale: Acute rejection occurs from 1 week to 3 months after the transplant; almost all transplant recipients experience acute rejection to some degree. Hyperacute rejection is rare and occurs within a few minutes of the transplant when the donor organ and recipient are extremely mismatched. Chronic rejection may occur at any time over the remaining lifetime of a recipient, causing varying degrees of damage to the donor heart. Subacute rejection is not a classification of rejection.
Question 2 of 5
The nurse is obtaining vital signs for a client in the clinic who has had a cardiac transplant. The nurse obtains an apical heart rate of 110 beats/minute. What is a priority action by the nurse?
Correct Answer: C
Rationale: The transplanted heart beats faster than the client's natural heart, averaging about 100 to 110 beats/minute, because nerves that affect heart rate have been severed. The new heart also takes longer to increase the heart rate in response to exercise. If the client is asymptomatic, there is no reason to obtain an ECG or notify the physician. The nurse would not administer the calcium channel blocker without a physician's prescription.
Question 3 of 5
A client is diagnosed with obstructive atherosclerotic plaque of the left carotid artery. What procedure does the nurse anticipate preparing the client for?
Correct Answer: A
Rationale: Endarterectomy is the resection and removal of the lining of an artery. This type of surgery is performed to remove obstructive atherosclerotic plaques from the aorta, carotid, femoral, or popliteal arteries. A thrombectomy is used to remove a thrombus for a vessel. An embolectomy is the removal of an embolus. Coronary artery bypass grafting is not indicated for the removal of an atherosclerotic plaque.
Question 4 of 5
A client is in the intensive care unit with a diagnosis of severe uncontrolled hypertension. What method of monitoring would best meet the needs of this client?
Correct Answer: B
Rationale: Direct blood pressure monitoring continuously displays the waveform and indicates the client's systolic, diastolic, and mean arterial pressures. This type of equipment eliminates the need to auscultate the BP. Direct BP monitoring may be used in clients with severe and sustained hypertension or hypotension and during and after cardiac surgery. Central venous pressure monitoring would be used to detect an excess or deficit in venous blood volume and would not be indicated for this client. Pulmonary artery pressure monitoring aids in the early treatment of fluid imbalances prevents left-sided heart failure or promotes its early correction and helps monitor the client's response to treatment and would not be indicated for this client. A manual reading is dependent on who takes the BP and can vary in its readings. It is not as accurate as the direct blood pressure monitoring.
Question 5 of 5
The nurse is measuring central venous pressure readings for a client receiving fluid resuscitation. Prior to obtaining the reading, what nursing action is required?
Correct Answer: B
Rationale: When measuring CVP, the nurse makes sure that the transducer is at the level of the client's right atrium; otherwise, an incorrect reading is obtained. The client is positioned supine or with the head slightly elevated but in exactly the same position as during previous measurements. Between CVP measurements, the head of the bed can be raised or lowered.
