Unit 20, 21

Question 1

right coronary artery (RCA)

Answer 1

supplies the inferior wall of the heart and the right ventricle

Question 2

right marginal artery

Answer 2

supplies blood to the right ventricle

Question 3

left coronary artery

Answer 3

supplies blood to the left side of the heart

Question 4

12 lead ECG

Answer 4

takes picture of heart at different angles to see blockage or delay of electrical current

Question 5

when do you use 12 lead instead of 4 lead

Answer 5

STEMI
ST- elevation myocardial infarction

if wave doesn’t go back to basline before going to northing

Question 6

atherosclerosis

Answer 6

refers to fatty plaque buildup within the wall of a coronary artery

Question 7

stenosis

Answer 7

narrowing of a blood vessel

Question 8

diastole

Answer 8

a phase of contraction where the coronary arteries are perfused

Question 9

what is STEMI caused by

Answer 9

caused by a complete occlusion of a coronary artery that results in ST segment elevation

Question 10

unstable angina

Answer 10

ischemic chest pain that occurs at rest without ECG or cardiac enzyme changes

Question 11

left anterior descending (LAD)

Answer 11

coronary artery supplying the anterior wall of the heart

Question 12

left circumflex (LCX)

Answer 12

coronary artery supplying the lateral wall of the left ventricle

Question 13

subendocardial ischemia

Answer 13

represents the ST segment depression on an ECG in the context of ischemic chest pain

Question 14

how much aspirin do you give

Answer 14

325 mg
four 81 mg chewable

Question 15

pericarditis

Answer 15

STEMI mimic that is the result of inflammation of the pericardium, that may result in widespread, concave ST elevation

Question 16

percutaneous intervention (PCI)

Answer 16

the standard of care for STEMI in the hospital

Question 17

anginal equivalents

Answer 17

signs of myocardial ischemia other than chest pains

Question 18

acute coronary syndrome

Answer 18

blanket term that includes unstable angina, STEMI, and NSTEMI

Question 19

treatments for ischemic chest pain

Answer 19

aspirin, nitroglycerin, oxygen if needed, narcotic analgesics

Question 20

if you want to give Nitroglycerin make sure:

Answer 20

blood pressure is 99mmHG

Question 21

infarction

Answer 21

death of heart tissue due to ischemia

Question 22

STEMI positive

Answer 22

1mm or more of ST elevation in 2 or more contiguous limb leads is positive for STEMI

Question 23

cariogenic pulmonary edema is most like to be the result of ____ ventricular infarct

Answer 23

left

Question 24

sgarbossa

Answer 24

criteria to identify STEMI in the presence of LBBB (left bundle branch block)

Question 25

how much nitroglycerin

Answer 25

3 doses (1 ever 5 mins) (if u want more, call medic control)

Question 26

angina caused by and relieved

Answer 26

due to strenuous activity insufficient blood flow to myocardium, narrowed arteries relieved with nitro or rest

Question 27

myocardial infarction caused by and relieved

Answer 27

occur at any time not relieved by rest

Question 28

anytime patient complains of chest pain

Answer 28

put on a 12 lead

Question 29

angina treatment

Answer 29

oxygen, nitroglycerin, aspirin, 12 lead

Question 30

acute myocardial infarction

Answer 30

THROMBUS -occlusion of blood flow caused by formation rough inner surface of diseased artery -can break loose and form embolism

Question 31

acute myocardial infarction (AMI) can cause

Answer 31

-Ischemia (injury & death of cell) -Dysrhythmia (electrical issue) - cardiogenic shock -sudden death (cardiac arrest within 2 hours)

Question 32

how do they treat AMI at the hospital

Answer 32

-fibrinolytics (therapy) -balloon angiplasty -aspirin -beta blocker (slows heart, widens blood vessels for more BP)

Question 33

left sided chronic heart failure

Answer 33

coughing up pink frothy sputum

Question 34

Aneurysm

Answer 34

-Weakened sections of arterial walls begin to dilate (balloon). -Bursting can cause rapid, life-threatening internal bleeding.
