What are the 2 main goals of IABP therapy?
Decrease the workload of the LV and reperfuse the coronary arteries.
Early IABP balloon inflation increases:
oxygen demand and decreases oxygen supply
Which of these is the most dangerous IABP timing error?
Early inflation
The IABP balloon should deflate at the:
very end of diastole
The Impella device has a purge fluid to:
prevent blood from entering the motor
If CPR is required when using an Impella device:
Decrease to P-2 and begin chest compressions
You notice the Impella purge flow rate increased from 12.8ml/hr to 13.1ml/hr, what is an appropriate action?
This is a normal automatic adjustment to the purge system.
What should be the highest point on your IABP arterial waveform?
Diastolic Augmentation Pressure.
This was marked as the correct answer, but doesn’t seem correct
How often do you need to zero an IABP with fiberoptic technology?
The fiberoptic recalibrates itself automatically.
Your patient has an Impella CP in place and you notice multiple suction alarms, what action should you take first?
Decrease the P level by 1 to release suction event and further assess patient.
Moderate hyperkalemia with a level of approximately 7mEq/L will show what type of tracing on an ECG?
Peaked T waves
What does an ECG record?
The electrical activity of the heart
According to the “turn signal method”, a RBBB has a QRS complex in V1 that is predominantly:
upright/positive
What causes the QRS to wide in a LBBB?
Delayed ventricular conduction
The electrode for lead V6 is placed in 5th intercostal space at the:
mid-axillary line
The chest leads are also called the:
precordial leads
How many electrodes are used to obtain a 12 lead?
10
Extreme axis deviation is cause when an electrical impulse originates:
in the ventricles
The vector of an electrical impulse typically travels in what direction?
down and to the left
The PR interval measures:
the time an electrical impulse is held at the AV node.
Two important questions to ask when evaluating a pediatric patient with asthma are
Prior admission to the ICU and prior history of intubation
Infants are ___ able to ____ their tidal volume, and therefore are able to compensate by ____ their respiratory rate.
Less, increase, increasing
What are the differences of the pediatric airway?
Floppy, U shape, Longer
In the asthmatic pediatric patient that is intubated and placed on the vent, the I:E ratio should be adjusted to
1:4 - 1:8
