RT EXIT EXAM 2025 QUESTIONS WITH
CORRECT ANSWERS
3 bottle drainage system - ANSWER-bottle 1- for drainage
bottle 2- water seal
bottle 3- suction control
Threshold resistor - ANSWER-aka PEEP VALVE
DEFIB - ANSWER-V FIB and
pulseless V TACH
Biphasic defibrillator - ANSWER-200 joules
Monophasic defibrillator - ANSWER-360 joules
Asystole - ANSWER-PEA
not a shockable rhythm- continue CPR
No IPPB for - ANSWER-untreated ptx (ptx with chest tubes are okay)
increased ICP
Pulmonary edema and CHF exacerbations can be treated with - ANSWER-CPAP
If you push in the air mix control on a IPPB machine, what FiO2 are you giving? -
ANSWER-100%
Systole - ANSWER-top number
pressure in the ventricles (specifically the left)
pulomonic and aortic valve have to be open
Diastole - ANSWER-bottom number
tricuspid and mitral valves have to be open for ventricles to fill with blood (REST)
12 lead ECG - ANSWER-12 different views of the heart
do not select unless it is a cardiac patient
only 10 leads are used
,P wave - ANSWER-atrial contraction
QRS - ANSWER-ventricular contraction
ST segment elevation or depression - ANSWER-MI
CAD
or ischemia of some kind in the heart
Triponin normal value - ANSWER-below 0.02
anything above indicate cardiac death as troponin is an enzyme produces by
myocardial ischemia
Where do the coronary arteries get their blood from? - ANSWER-the aorta
LAD - ANSWER-left ventricular ascending (on the front side)
aka the widow maker
if there is an obstruction here, most of the heart will not be provided with O2/blood
Digitalis - ANSWER-cardiac drug that stabilizes a rhythm
The heart should be no larger than _________ the diameter of the chest. If it is, it is
called ___________. - ANSWER-1/2
cardiomegaly
Kerly B and Kerly A lines - ANSWER-means interstitial edema > pulmonary edema>
due to left heart failure
aka cardiogenic pulmonary edema
increased CVP, PAP and SUPER increased PCWP
decreased CO and SV
Values of CHF/ Pulm edema - ANSWER-increased CVP, PAP and SUPER increased
PCWP
decreased CO and SV
non-cardiogenic pulmonary edema - ANSWER-normal size heart
increased CVP and PAP with NORMAL PCWP
, ARDS
Swan gans - ANSWER-distal- draw
proximal- push
thermistor- C.O. measurement by changing the temperature
PCWP is the best indicator to tell the difference between - ANSWER-cardiogenic
pulmonary edema (will be elevated) and
non-cardiogenic pulmonary edema (it will be normal)
Normal CaO2 and CvO2 - ANSWER-16-21% (20 Vol%) CaO2
15 Vol% CvO2
If the C(a-v)O2 is small - ANSWER-less than 4 Vol%
then C.O. is going UP and this could be SEPTIC SHOCK or ASTHMA
If the C(a-v)O2 is large - ANSWER-more than 6 Vol %
then C.O. is going DOWN
If the C(a-v)O2 is going UP and you recently increased the PEEP, then you are
_______________. - ANSWER-Decreasing the C.O.
How do you fix an intrapulmonary shunt? - ANSWER-with positive pressure to recruit
alveoli
PvO2 (mixed venous) normal - ANSWER-35-45 torr
When C.O. drops so does - ANSWER-PvO2 (mixed venous)
Peak and Plat pressures go ___________ in ARDS patients. - ANSWER-UP
Can you measure a spontaneous breath on PRVC? What is the difference between
PRVC and AC? - ANSWER-NO! It is similar to AC where if the patient triggers a breath,
they will receive what has been set.
The pressure is set at a point to not exceed and the vent will titrate this but NOT go
above the pressure while giving the set Vt
in AC, the patient will trigger and get what is set but if the pressure is going above what
we have the alarm set to, it will still give the Vt, despite going past the alarmed pressure
