CRNI: Technology and clinical application Practice Test Exam
with Correct Q & A 2023/2024
A femoral line can remain in place no longer than ______ hours. correct answers 4
The goal of PICC placement is to end in the ________ juncture. correct answers Cavalatrial
Proper PICC placement can be confirmed by EKG by _________? correct answers Peak in P wave
3 layers of the vein anatomy correct answers Tunica intima, tunica media, tunica adventitia
tunica intima correct answers the innermost layer of a blood vessel, composed of a single layer of cells;
the only tissue in the body that platelets do not stick to.
tunica media correct answers The middle and thickest layer of tissue of a blood vessel wall, composed of
muscle cells that allow the vessel to expand or contract in response to changes in blood pressure and
tissue demand.
tunica adventitia correct answers The outer layer of tissue of a blood vessel wall, composed of elastic
and fibrous connective tissue. Important not to drag needle against this layer, otherwise vein will
constrict
Allen's test correct answers Is the process of occluding the radial artery and ulnar artery at the same
time, maintaining pressure until the pt's hand turns white, then releasing the ulnar artery and observing
for blood return to the hand to assure adequate circulation via ulnar artery to allow placement of a
catheter into the radial artery.
What can cause dampened wave forms from an arterial line? correct answers Catheter tip against artery
wall or catheter is kinked
Ischemia or necrosis of the area can be a complication of an arterial line caused by _____? correct
answers Embolisms (air, thrombus, catheter, particulate matter)
Rotate arterial site every _____ hrs. correct answers 96 hrs
Administration set (dome and pressure tubing) change every _____ hrs. correct answers 48
How long do you apply pressure after an inadvertent arterial puncture? correct answers 4-6 minutes
The recommended dwell time for peripheral midline is _____? correct answers 4 weeks or less
Does a midline (tip ending below the axillary) need xray placement confirmation? correct answers No
Recommended dwell time of PICC line? correct answers Unknown/not studied
Recommended dwell time for a non-tunneled percutaneous catheter correct answers 3 to 10 days
