SOLUTIONS RATED A+
✔✔What do you know regarding ischemia that is confined to only the posterior and or
lateral segments of the left ventricle? - ✔✔difficult to detect by ETT
✔✔What three conditions definitely alter the results of echocardiography in determining
CAD? - ✔✔obesity, rapid heart rate and lung disease
✔✔Specifically, when is an ETT considered to be negative? - ✔✔patient exercises to
85% of age predicted maximum heart rate without evidence of induced ischemia
✔✔All patients, even is asymptomatic, require risk stratification according to the
Farmingham risk score. At present, ACC/AHA guidelines, however, do not normally
support stress tests for asymptomatic patients without addiitonal justification. From the
list below, what could be used to justify a ETT in an asymptomatic patient? -
✔✔sedentary and wishes to begin aggressive exercise
✔✔Abdominal aortic aneurysms are often asymptomatic. What percent of AAA's are
discovered in asymptomatic patients? - ✔✔75%
✔✔Improvements in the delivery and management of healthcare are necessary if we
are to improve the overall health of this nation's population. Which of the following are
identified in your readings as strategic in the movement to improve the healthcare
system? - ✔✔population management and healthcare practice
✔✔What are the two main types of heart failure? - ✔✔left sided and main
✔✔Maintenance of an Isometric ST-segment during exercise is the response of? - ✔✔a
normal heart
✔✔The goal of self-management is to specifically do what? - ✔✔engage patients in
their own care
✔✔Your 56-year old patient presents with bradycardia with a rate of 55 and first degree
AV block. The patient is hemodynamically stable and is not experiencing any syncope
or chest pain. History includes previous myocardial infarction. Home medications
include beta blockers, daily aspirin. Lab work is non-significant for electrolyte imbalance.
You decided to treat this patient for the arrhythmia to prevent future destabilization.
From the choices below, which might be the appropriate first measure to consider? -
✔✔discontinue beta blocker and replace with another therapy if necessary
✔✔Your patient is morbidly obese and cannot sit on a bicycle or walk a treadmill. She
also has marked and severe emphysema. You need to make an assessment of the risk
, of significant CAD and your patient's family says that their relative had their diagnosis
based on an ultrasound echocardiography. What facts would influence your decision
regarding the family request for echo assessment? - ✔✔sensitivity would be reduced
because of obesity and lung disease
✔✔You are in the clinic with your mentor observing the Echocardiogram exercise test of
a 45-year old male that has been experiencing slight chest pressure almost daily during
exercise. While observing your patient, your mentor points out that the left ventricle wall
is thinning and there is some hyperkinesias of the ventricular wall. From your time in the
clinic, you know that this test will be considered to be what type of result? - ✔✔positive
✔✔Your patient is newly diagnosed with persistent Atria Fibrillation. You consider
electrocardioversion. Before undergoing this procedure you should order the following
examination to assess thrombus risk. - ✔✔Tranesophageal echocardiography
✔✔Tachyarrhythmias cause a drop in commonly blood pressure, cardiac output,
syncope, shortness of breath, and chest pain. What phenomenon most often occurs
during these arrhythmias to cause these symptoms? - ✔✔shortened diastole
✔✔At what age is atria fibrillation most common? - ✔✔60 years or older
✔✔Automaticity is a property common to all cardiac cells. Is this statement true or
false? - ✔✔true
✔✔Your patient has a maximum age-predicted heart rate of 180. During the exercise he
reaches a heart rate of 140 and then states he can no longer exercise. You see
evidence of ischemic changes on the ECG. This would be predictive of what condition?
- ✔✔significant CAD
✔✔You tell a patient that he has a murmur. He says he has been told this before, but
wonders what causes the unique sounds of a murmur. Which of the following would be
your best option? - ✔✔turbulent flow of blood
✔✔Any patient presenting with symptomatic bradycardia should be referred to a
cardiologist for management. Is this statement true or false? - ✔✔true
✔✔Encouragement of patients to take effective actions in their own healthcare refers to
the concept of: - ✔✔self-management support
✔✔You are considering adding an adjunctive form of testing to detect wall motion
abnormalities during the ETT. You select Echocardiography as the added testing. You
choose this test because you know that echocardiography does what when added to a
standard ETT? - ✔✔enhances sensitivity and specificity of CAD detection
