What is foodborne transmission? |
Food contaminated with a pathogen. |
|
# 1 way to break the chain of infection? |
Handwashing |
|
Pacemaker of the heart? |
SA node. |
|
electrical conduction system of the heart. |
SA node- AV node- bundle of his- left and right bundle branches- purkinje fibers. |
|
Artifacts |
Study alternating current, somatic, and wandering baseline. |
|
Know cardiac cycle |
P wave atrial depolarization, QRS ventricle depolarization, T wave ventricle repolarization, U wave not usually seen but associated with ventricle repolarization. |
|
Standardization mark dimensions |
2mm wide 10mm high. Normal standardization let's MA know machine is properly calibrated. |
|
Normal running speed of an ekg |
25/mm sec or 25mm/mv. ( MV equals millivolts) |
|
Gain vs amplitude |
When you increase the amplitude you also increase the gain on the machine. |
|
Holter monitor |
Portable ambulatory electrocardiograph |
|
Holter monitor records |
Continuous recording of cardiac activity for at least 24 hours. |
|
Patient activity diary |
Record all activities- physical, emotional, sexual, sleep and times. |
|
Contraindication. (Contra=against) |
used to say that something (such as a treatment, procedure, or activity) should not be done or used in a particular situation for medical reasons. |
|
Stress test instructions |
No tobacco, no caffeine, no alcohol 3 hours prior to test. |
|
Medicine stress test instructions |
It's should take their normal medications unless otherwise instructed. |
|
Beta blockers |
Should be avoided specifically for the heart prior to a stress test. |
|
When PT experiences extreme fatigue. |
The stress test should be stopped. |
|
Dextrocardia |
Condition where the heart is pointed towards the right side of the chest. Electrodes go on right side of chest and arm leads are flipped (RA goes on LA) |
|
Telemetry |
Way of monitoring the heart while hospitalized (looks for pattern of your heartbeats to spot heart probs and monitor effectiveness of medications) |
|
Telemetry unit. |
5 colored wires attached to it with 5 sticky pads that are attached to PT's chest. |
|
Limb leads. |
LL= Left leg, RL= Right leg the ground ( when referring to the ground it is the right leg), LA= Left arm, RA= right arm. |
|
If PT has no legs |
Place electrodes on lower portion of abdomen, above the pelvic cavity. |
|
HEP A |
Transmitted via fecal oral route (affects the liver) |
|
HEB B & C |
Transmitted via a needle stick (affects the liver) |
|
Sepsis |
Something contaminated with a pathogenic microorganism. |
|
Asepsis |
Abscence of pathogenic microorganisms |
|
What goes in biohazardous bag |
Anything contaminated with bodily fluids except sharp objects. |
|
What goes in a sharps container? |
All sharp objects contaminated with bodily fluids. |
|
Which pulse is checked during emergency situations and during CPR? |
Carotid pulse. |
|
What is an interval? |
Waveform plus a segment |
|
QT interval goes from? |
Beginning of QRS complex to the end of the T wave. |
|
PR Interval goes from |
The beginning of the P wave to the beginning of the QRS complex. |
|
Counting Horizontal boxes calculates |
PT heartrate |
|
Dimensions of the squares |
Small 1mm by 1mm, large 5mm by 5mm |
|
A 3 lead ekg monitors |
Bipolar leads 1, 2 and 3 |
|
3 categories of leads. |
Bipolar, chest , augmented |
|
Lead angles |
Lead 2 records from the right arm to the left leg. ( lead 2 shows the heart rhythm clearer then all the other leads) |
|
Lead AVR angle |
Records from the right arm and a central location between the left arm and the left leg. |
|
Bipolar and augmented leads |
Record side to side and top to bottom of the heart. |
|
Leads V1-V6 ( chest leads) |
Record from front to the back of the heart. |
|
Dysrhythmia & arrhythmia |
Are synonyms for an irregular heartbeat. BOTH MEAN ABNORMAL RHYTHM. |
|
Normal QRS complex measures |
0.06-0.10 seconds |
|
A normal PR interval measures |
0.12-0.20 secs |
