100% Correct!!
What is the purpose of zeroing invasive pressure monitoring? When
is it done? -
correct answer ✅put to atmospheric pressure
confirms that when pressure within system is zero
done by opening reference stopcock to room air
-may be once a shift
-per hospital policy
-if system is disconnected from monitor
-when changing system (bag/tubing)
nob off to pt -->open to air to zero-->new red cap to replace
ECG line
Arterial line
PA pressure line
SPO2

Respiratory rate
noninvasive BP -
correct answer ✅
Which lines are used for invasive monitoring? -
correct answer ✅Arteries (blood pressure)
Veins (CVP)
Lungs (PA)
Abdomen (Bladder)
Pressure line does not always have to be arterial

100% Correct!!
Could be distal port (brown) of central line
What is a reason to measure bladder pressures? -
correct answer ✅Measuring intra abdominal pressure can be a
way to assess compartment syndrome
Organs swelling can cut off circulation- may not be able to breathe
supine d/t high thoracic pressures. Abdominal HTN starts at 12
mmHg
What can be used to flush arterial line? -
correct answer ✅ONLY normal saline and only a very small amount
What test should be done before taking an ABG? -
correct answer ✅Allen's test
Where is the location of the phlebostatic axis? -
correct answer ✅midaxillary and 4th intercoastal space

100% Correct!!
What determines a positive or negative allen's test? -
correct answer ✅Positive when normal color does not return
within 7 seconds- negative when it does
Why is it important to zero reference the transducer and perform a
dynamic response (square wave) test during initial setup of the
equipment? -
correct answer ✅Transducer too high, blood pressure will read
low, too low it will be a false high
What is the purpose of a square wave test? -
correct answer ✅Recognize good arterial line vs not good
Square wave test -
correct answer ✅Observe waveform sharply rise and "square off",
release flush and the waveform returns to baseline—count the
number of oscillations and observe distance between them.
Square wave test
