100% correct answers (latest
update)
Oxygen is exchanged with CO2 at the terminal end of the ________ by
the process of diffusion via the capillary membrane - answer alveoli
CPAP - answer continuous positive pressure airway throughout
inspiration and expiration
uses: sleep apnea, mechanical intubation weaning
BIPAP - answer bilevel positive airway pressure works by providing
assistance during inspiration and preventing airway closure during
expiration.
uses: severe sleep apnea, COPD
Prior to a ABG collection, a Allen test is performed; normal return of
blood flow is - answer within 6 seconds
A patient shows s/s of anxiety prior to intubation; an ____ should be
collected - answer ABG
Balloon pressure with ET tube that is below 20 can cause - answer
aspiration pneumonia
Balloon pressure with ET tube that is above 25 can cause - answer
trachea bleed/rupture, ischemia, necrosis
, Extubation by the patient can cause - answer laryngeal swelling,
aspiration, hypoxemia, low blood pressure, death
disadvantages of a ET tube - answer decreased cough and
swallowing reflex, risk for aspiration, risk for infection, risk for ulcer
of the trachea
a __________ line suctions the ET tube consistently - answer sub-
clottial
what needs to be at the bedside for a patient with a tracheostomy? -
answer opirator
what position does a patient need to remain in that has a trach? -
answer semi-fowlers
how often do you need to assess the pressure gauge for a trach? -
answer q 8 hrs
should be 20-25 mmhg
how do you check the placement of a ET tube? - answer CXR
can also be assessed by a CO2 monitor and a laryngoscope, CXR is
best; CO2 = in lungs
what are the complications of a trach tube? - answer tube
dislodgment, pneumothorax, SUBq emphysema, air emboli,
laryngeal nerve damage, rupture, necrosis, tracheal wall
penetration, aspiration
