ALU 301 Chapter 6 Quiz

Question 1

EKG abnormalities are categorized into all of the following areas EXCEPT:

• cardiac hypertrophy
• heart rhythm
• ejection fraction
• axis or position of the heart

Answer 1

ejection fraction

Question 2

All of the following statements regarding electrophysiology procedures are correct EXCEPT:

• it is called HIS bundle procedure
• it does not attempt to induce arrhythmias
• it measures the heart conduction system
• it is used to distinguish impulse formation disorders

Answer 2

it does not attempt to induce arrhythmias

Question 3

All of the following statements regarding heart murmurs are correct except:

• the intensity of the murmur is related to the severity of the valvular impairment
• high pitched sounds of short duration occurring in systole are often associated with mitral valve prolapse
• physicians capture accurate descriptions of a murmur via physical exam using a stethoscope
• A grade 2 murmur is described as soft but easily heard

Answer 3

physicians capture accurate descriptions of a murmur via physical exam using a stethoscope ( doctors rely more on an echo for clinical classification)

Question 4

Which of the following cardiac tests is the most sensitive for the diagnosis of CAD?

• EKG
• stress echo
• stress EKG
• CT angiogram

Answer 4

CT angiogram

Question 5

All of the following are types of murmurs EXCEPT:

• systolic
• diastolic
• inorganic
• continuous

Answer 5

inorganic

Question 6

The test that uses high frequency impulses to visualize the structure and function of the heart is:

• holter monitor
• EKG
• echo
• transesophageal echo (TEE)

Answer 6

echo

Question 7

All off the following lab tests are used to identify an acute coronary syndrome EXCEPT:

• troponin I
• CPK-MM (also known as CPK-3)
• lactic acid dehydrogenase (LDH)
• aspartate aminotransferase (AST)

Answer 7

CPK-MM
(CPK-BB and CPK-MB are used. CPK-MM is found mostly in skeletal muscle)

Question 8

The diagnostic finding most related to CAD on a stress test is:

• ST segment depression
• presence of arrhythmias
• PR prolongation
• inverted P waves

Answer 8

ST segment depression

Question 10

The best indicator of the hearts left ventricular function is:

• heart rate
• ejection fraction
• septal wall thickness
• left ventricular posterior wall thickness

Answer 10

ejection fraction

Question 12

ST segment changes seen on a stress test are likely related to coronary artery disease EXCEPT:

• those seen prior to exercise

Answer 12

those seen prior to exercise

A, B, and C are correct

Question 14

Which of the following statements regarding troponins is/are correct?

A - they are normally found in trace quantities in the blood
B - they are the most sensitive and specific biomarkers for myocardial damage
C - they are elevated only when other biomarkers are elevated

B only is correct
C only is correct
A & B are correct
B & C are correct

Answer 14

A and B are correct

Answer 16

Bayes theorem

Question 17

Hypokinesis as it related to an echocardiogram is:

• increased heart wall motion

• reduced heart wall motion
• normal heart wall motion

Answer 17

reduced heart wall motion
