1

What is a non-invasive assessment?

An observation indicating an impairment of cardiac function is decreased level of consciousness

2

How does Mucus Membrane Color help with assessment?

The color is a reflection of hemoglobin saturation in the capillary blood

3

If Cardiac function is ______, pulse will be affected.

impaired

4

What is "Auscultation of Heart Sounds?"

Auditory examination of the heart.
- Done with a stethoscope over the valve, chamber or great vessel

5

What can Vectocardiogram assist in finding?

1) precisely locate the site of myocardial infarction
2) diagnose conduction defects
3) diagnose chamber hypotrophy

6

On a vectocardiogram, where are they placed?

fiver over the pericardium
one on the left leg
one in the back of neck

7

What is Pulse Tracing?

Pulsation described by the flow of blood through the artery during CC
can be drawn as a waveform potting pressure against time

8

What is an Echocardiogram?

ultrasonic sound waves that generate and direct into the cardiac structures and reflect waves at different angles and lengths according to structure and density

9

What is a Doppler Study?

Made by using a handheld microscope placed on the skin over a lubricating gel

10

What does a Chest X-ray show?

examination of the size and contour of the heart and related structures are visualized

11

What is an invasive assessment of function?

Greater risk of the individual study

12

X-ray with barium shows a cardiac silhouette shows a enhanced image than a single chest x-ray alone.
T/F

True

13

Cardiac Cauterization
For a right-heart cath, the cath is placed in the _____ or _____ artery

Brachial or Femoral

14

Cardiac Cauterization
For a left-heart cath, the cath is commonly placed in the ____ artery

Femoral

15

Once the cath is placed and guided into the atrium:

- pressures are recorded
- blood samples are obtained to examine oxygen content
- contrast medium is injected to visualized chamber function and valve patency

16

Once the cath is passed into the ______, the sequence is repeated

ventricles

17

What is a Coronary Angiography?

Fluoroscopic visualization of the coronary arteries and left heart structure using an (iodine) contrast dye.

18

What is another name for Coronary Angiography?

Arteriography

19

Hot and Cold spot Imaging
Nuclear imaging with radiohead pharmaceuticals:

1) conflicting history for myocardial infarction
2) Equivocal ECG abnormalities
3) an individuals cardiac enzymes have been elevated because of surgery or trauma
