Postoperative dysrhythmias, specifically atrial dysrhythmias, are common in the first three days
following CABG surgery. Although dehydration, paralytic ileus, and acute respiratory distress
syndrome could occur, they are not common complications. - ✔✔The nurse is providing
postoperative care to a patient who underwent coronary artery bypass graft (CABG) surgery. For
which common complication would the nurse monitor the patient?
Morphine sulfate is the drug of choice for a patient with unrelieved chest pain, even after the
%
administration of nitroglycerin. Esmolol is a β-blocker used to slow down the heart during minimally
invasive direct coronary artery bypass (MIDCAB). Docusate is a stool softener that facilitates bowel
movements. Ticagrelor is used in dual antiplatelet therapy on a patient with ongoing angina and
negative cardiac markers. - ✔✔A patient who has received a maximum dose of nitroglycerin
continues to report chest pain. Which medication would the nurse anticipate administering to this
patient next?
-Esmolol
-Docusate
-Ticagrelor
-Morphine sulfate
-Inferior wall
Blockage of the right coronary artery may result in an inferior wall MI because the right coronary
artery supplies blood to the inferior wall of the heart. Damage to one or more other coronary arteries
may result in anteroseptal and anterolateral MIs. Anterior wall infarctions result from blockages in the
left anterior descending artery. - ✔✔In which location would a myocardial infarction (MI) occur due to
blockage of the right coronary artery?
Papillary muscle dysfunction occurs if the papillary muscles attached to the mitral valves are involved
in infarction. A patient may have papillary muscle infarction if a murmur is heard upon auscultation at
the cardiac apex. The presence of S3 and S4 sounds of the heart and crackles in breath sounds
indicate heart failure. The deep sound heard at the lower left sternal border upon auscultation
indicates acute pericarditis. - ✔✔The nurse assesses a patient who has been diagnosed with
papillary muscle dysfunction. Which observation supports the patient's diagnosis?
-S3 heart sound
-Murmur at the cardiac apex
-Crackles in bilateral lung bases
-Deep sound at the lower left sternal border
-Small incisions are made between the ribs.

-A mechanical stabilizer is placed to immobilize the operative site.
-A thoracoscope or robotic assistance is used to free the internal mammary artery.
MIDCAB offers patients with disease of the left anterior descending or right coronary artery an
approach to surgical treatment that does not involve a sternotomy and cardiopulmonary bypass
(CPB). It involves several small incisions between the ribs to dissect the internal mammary artery
(IMA) with a thoracoscope or with robotic assistance. The heart is then slowed or stopped temporarily
with adenosine, which is assisted by a mechanical stabilizer to immobilize the operative site. The IMA
is then sutured to the coronary artery. A robot is used to replace the mitral valve during robot-assisted
cardiothoracic surgery. Transmyocardial laser revascularization involves cardiac catheterization.
Mechanical stabilizers are used on a - ✔✔A patient is scheduled for a minimally invasive direct
coronary artery bypass (MIDCAB). Which steps are involved in the procedure? Select all that apply.
-A robot is used to replace the mitral valve.
-Small incisions are made between the ribs.
-Cardiac catheterization is performed during the procedure.
-A mechanical stabilizer is placed to immobilize the operative site.
-A thoracoscope or robotic assistance is used to free the internal mammary artery.
-Brisk walking (3 to 4 miles per hour)

Physical activity improves the physiologic functioning and psychologic well-being of a patient with
acute coronary syndrome. Therefore the nurse should encourage the patient to walk at a rate of 3 to
4 miles per hour. Painting while seated is a low-energy activity. Carpentry and running at 7 miles per
hour are high-energy activities for a patient with acute coronary syndrome. - ✔✔The nurse provides
a list of health-promoting regular physical activity examples to a patient with coronary artery disease
(CAD). Which activity would the nurse include on the list?
-Painting while seated
-Performing carpentry
-Jogging (7 to 8 miles per hour)
-Brisk walking (3 to 4 miles per hour)
-Implantable cardioverter-defibrillator (ICD)
The most common approach to preventing a recurrence is the use of an ICD. It has been shown that
an ICD improves survival compared with drug therapy alone. Drug therapy and a PCI will not prevent
a recurrence of SCD. A CABG is not necessary. - ✔✔A patient who survived an episode of sudden
cardiac death (SCD) is recovering in the intensive care unit (ICU). Which intervention would the nurse
anticipate to prevent a recurrence?

Myoglobin is a serum cardiac marker that is released into the circulation within two hours after an MI.
Myoglobin's role in diagnosing MI is limited because it lacks cardiac specificity. Creatine kinase-MB
(CK-MB) levels begin to rise about six hours after an MI, are specific to myocardial cells, and help
quantify myocardial damage. Cardiac-specific troponin T (cTnT) and cardiac-specific troponin I (cTnI)
are highly specific indicators of MI. - ✔✔Cardiac biomarker levels are being evaluated for a patient
who is suspected of having a myocardial infarction (MI). Which biomarker lacks specificity for
diagnosing an MI?
-Myoglobin
-Creatine kinase-MB (CK-MB)
-Cardiac-specific troponin I (cTnI)
-Cardiac-specific troponin T (cTnT)
