NURS 5355 FINAL EXAM WITH COMPLETE
SOLUTIONS 100% VERIFIED
CI to CVC placement? - ANSWER No absolutes; Relative:coagulopathy &
thrombocytopenia- plt <50, INR >1.5, PTT >50
preferred subclavian vein approach? - ANSWER infraclavicular
IJ risk? - ANSWER arterial cannulation
SC risk? - ANSWER pneumo/hemo
Femoral risk? - ANSWER infection/thrombosis
site for emergent lines? - ANSWER Femoral artery and vein
sufficient collateral circulation? - ANSWER color return within 5 seconds or less
lines placed percutaneous - ANSWER through the skin (not open approach)
common ALine sites? - ANSWER Radial then Femoral
radial artery catheter approach? - ANSWER lateral to medial to stabilize artery against
flexor carpi radialis tendon
Aline steps? - ANSWER insert catheter/needle, then stabilize the introducer and
advance guide wire using actuating lever, push needle/catheter another 1-2mm, hold
, wire and remove needle while advancing catheter, remove wire
gold standard of measuring MAP in both critically and chronically ill patients? - ANSWER
PAL
common and less severe complications of ALine placement? - ANSWER temporary
occlusion due to arterial spasm, hematoma, and bleeding
RICE or pressure to treat
zero ALine to? - ANSWER midaxillary line, 4th intercostal space, Phlebostatic axis
Most common PAL placement complication? - ANSWER Thrombosis
lung disease determine by? A-a gradient? - ANSWER increased; difficulty getting O2
from alveoli to the blood
A-a gradient normal? - ANSWER reduced alveolar ventilation/hypoventilation
measurement of O2 dissolved in the blood? - ANSWER PaO2
O2 attached to hemoglobin molecules? - ANSWER oximeter- O2
elevated carboxyhemoglobin? - ANSWER CO poisoning
<pO2 60 & <O280%, oxyhemoglobin saturation curve? - ANSWER steep, large changes
in oximetry mean small changes in oxygenation
Increased PaCO2? - ANSWER reduced alveolar ventilation
vein blood flow? - ANSWER dark nonpulsatile flow- unless hemodynamic compromise
