Final exam 1st year Flashcards
catheter with one curve is called
amplatz left
catheter with two curves is called
jl4
most common cause of ECG artificat is
poor skin prep
bulging or aneurysmal LV wall segment is termed
dyskinteic
fuzzy looking ECG is
60 cycle ac poer
wandering ECG is called
baseline drift
bradycardic and pt ECG has a fall of BP to 80/50
have the pt cough
what hemodynamic tracings are likely to contain c waves
atrial
standard ECG gain
1mv=1cm
by definition Nonsustained vtach lasts
less than 30 seconds
The T wave on an ECG corresponds to phase ___of the action potential
3
the pt has as. you cross av with AR1 Cath. You measure LVedp at 31. for LV gram what do you do next
administer 200mcg of intraventricular nitroglycerin to try to lower the EDP before proceeding
pacing mode that indicates atrial sensing only but both sensing and pacing in the ventricle
VDI
after stent BP drops to 84/52
dopamine IV at 10 mcg/kg/min
distance between the proximal and distal ports of a swan Ganz cath
30 cm
A lao 45 degree view of the cardiac arteries is done to
profile the RCA
highest velocity of backward blood flow is from
MR
pulsus alternans with st segment elevation during insertion of a TVP into RV suggests
RV failure
physician has to cut through heavy muscle. which sisscors most appropriate
curved mayo
max dose of nitroglycerin for treatment of hypertensive crisis is________ If BP remains high, try another medication
200 mcg/min
swan Ganz catheters should be connected to a continuous flush device which at 300mmHg infusion pressure will deliver
3-8ml flush/hr
diseases that causes an increased diastolic gradient between right and left ventricles
CP
your pt blood gas returns with low pH a low pco2 and a low bicarbonate level, you suspect
compensated metabolic acidosis
the appx percentage of o2 delivered by a simple facemask at 8-10 L/min
40%-60%
the dosage range for intravenous Lasix is
20-200mg
bumetadine drop 4mcg/kg/min. your pt Isabel e Aiken weighs 140 Ibs and cannot urinate. you mic 10 mg bumex of D5W. How fast should your infusion run in ml/hr
154ml/hr
finding a pulse, making a small decision and puncturing and pulling back leaving the stylet in place is called
modified seldinger technique
on power injector the time from when you push the exposure switch to the delivery of the programmed rate for the contrast is called rate of rise or
transition time
on the power injector the max pressure is measured in
PSI
The brachial cutdown approach or the cardiac Cath is called
sones technique
a catheter measured as 3F is equal to
1mm
the purpose of the hearing device on the contrast injector is to
decrease contrast viscosity
which vascular closure devices has a suture that is self tightening
preclose
a patient is noted to have a hematoma post procedure and manual pressure is held. if ongoing bleeding is stopped, the hematoma will usually resolve in
1-2 weeks
why are bleeding complications related to a back wall arterial stick using the seldinger less likely to happen
the stylet punctures the wall spreading the fibers rather than cutting them as with the single wall needle
methods requires the use of external pacing pads
transcutaneous
drug that is contraindicated to reverse the effects of heparin in a patient that has an allergy to egg white prior to a sheath removal
protamine sulfate
lab test is preformed to verify protamine sulfate effect and what result is needed prior to sheath pull
ACT >180 s
what complication is associated with mechanical cardiac valves
thrombus formation
minimum amount of ma required to elicit a a ventricular response
temporary pacemaker
which ofd the following can finish the validity of ventriculography
catheter tip too close to the mitral valve
chief complaint of MR
shortness of breath
condition that results from the PCW pressure exceeding oncotic pressure of plasma proteins
CHF
what length diagnostic guidewire is needed to exchange a JR4 or an IMA catheter in the subclavian artery
260cm
the rao projection provides the best imaging of which LV walk
anterior;inferior
when the fluoroscopic c arm is angled into a cardiac view so that the x-rays exit from the pt’s left abdominal area what angiographic view is this
caudal LAO
which artery is sometimes seen branching directly from the aorta
conus
Your patient Jack Hacker, a code monkey known to his friends as
Cyber Jack, presents in the cath lab with an acute myocardial infarction. He
develops ventricular tachycardia and immediately loses consciousness. He
is pulseless and not breathing. Which should be done first?
deliver an unsynchronized shock
You are administering magnesium sulfate to your patient Ms. Alberta
Einstein, a bagel maker who works at light speed. Not now, she is in cardiac
arrest. The recommended dose is:
1 to 2 g diluted in 10 ml slow IV push
Your patient Mr. Jim Carjackian, a reality TV star on Grand Theft
Auto, has pulseless electrical activity. While considering treatable causes,
an IV is started and a saline infusion begun. The first medication you should
give is:
Epinephrine 1 mg IV
