Norepinephrine
Levophed (alpha & beta)
Peripheral vasoconstrictive action by stimulating alpha adrenergic receptors
Nitroglycerin tabs deteriorate when exposed to - Answer-air and light
Also deteriorates in PVC plastic tubing and bags, so it's often mixed in glass

defibrillators are charged from 50-360 Joules of energy
Tridel - Answer-Tridel, Nitroglycerine counteracts the Erg's precipitated coronary
vasospasm
transducer converts - Answer-one form of energy into another
Thermistors transducer - Answer-temperature into electrical energy
Zero Transducer - Answer-13.6 mmH2O
Piezoelectric transducers (crystals) - Answer-electrical wavers into ultrasound waves
then they record the reflected pressure waves and convert them back to electrical
energy so we can view the echogram
,Medical pressure transducers - Answer-convert BP energy inot electrical energy
asepsis means - Answer-absence of infectious agents
aseptic skin prep is directed at cleanliness and eliminating alcl infectious agents or
pathogens
skin cannot be sterilized as microorganisms or resident skin flora live with us constantly
and are considered nonpathogenic
Isometric (static) exercise - Answer-pushing against a wall
Increase BP and systemic vascular resistance
with LITTLE changes in CO and O2 demand consumption
Isotonic (dynamic) exercise - Answer-muscular contraction of large muscle groups that
results in movement
calcified plaque is often associated to what - Answer-unstable angina,
thrombus formation
myocardial infarction
considered a "complicated lesion" is an unstable ruptured plaque
ASHD plaque - Answer-atherosclerotic heart disease
THREE PHASES
1. FATTY STREAKS
2. RAISED FIBROUS PLAQUES
3. COMPLICATED LESIONS ARE CALCIFIED FIBROUS PLAQUES , which rupture,
hemorrhage in the plaque and/or thrombus.
Stunned mycardium - Answer-brief period of severe coronary ischemia the LV
dysfunction may gradually improve over a three hour period
hibernating myocardium - Answer-recovers over a period of days or months
dyskinetic - Answer-LV wall bulges
severely ischemic areas
hypokinetic - Answer-LV wall fails to contract
more mildly ischemic areas
Prinzmetal or variant angina occurs - Answer-at rest without warning
due to coronary spasm, not CAD
EMD electromechanicalbb dissociation is termed - Answer-Pulseless Electrical Activity
or PEA
, state with organized electrical depolarization in heart, but not contractions or
undetectable.
Synchronized cardioversion - Answer-treats AFib/flutter and SVT arrhythmias
If meds fails, get good ECG
SYNCHRONIZE THE DEFIB PULSE TO R WAVE
RRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR

Heart biopsy - Answer-Left heart - 5000 units heparin - no protamine
Right heart - no heparin
Valium, Diazepam - Answer-Most common anti anxiety agent used
Ergonovine and methergine - Answer-require nitroglycerin on hand
Ergo maleate and Methergine stimulate alpha-adrenergic and serotonin receptors in
smooth muscle of coronary and can cause spasm in Prinzmetal angina pts
Ergo not used much in US and was replaced by Methergine
Also used to stimulate uterine muscle contractions during birthing
Increased iodine in contrast makes it - Answer-radiopaque due to heavy metal that
absorbs x-ray
cimetidine prednisone - Answer-iv meds given with benadryl for prophylaxis
amrinone, milrinone - Answer-Increases cardiac contractility, vasodilator.
Blood pressure support
It can treat congestive heart failure
digitalis - Answer-Treats CHF atrial arrhythmias.
Increases blood flow and reduces edema in hands and ankles
Strengthen the force of the heartbeat by increasing the amount of calcium in the heart's
cells. (Calcium stimulates the heartbeat.)
Loxaglate, hexabrix - Answer-low-osmolar contrast agent is much safer and
