Seminar 2 Flashcards
How is high flow oxygen measured
measured in % of O2 instead of L/min
does high flow O2 have to be humidified
Yes
how much do you titrate high flow oxygen
titrate it by 5-10% each time
How long can a person be on high flow oxygen
usually only left on for 7 days
what is the definition of high flow oxygen
when the flow rate is higher than the inspiratory rate of the patient so the patient doesn’t breath any room air
what info should be on the label of all oxygen equipment
always label with the pt’s name and the date
is optiflow or airvo considered an AGMP?
No since it only turns the water into vapor not an aerosol
how often should a nurse assess the settings flow temp and sterile water bag on optiflow or arivo system
should be accessed at least every 4 hours
for the first 24 hours a patient is on optiflow or airvo how often do you need to access patients resp status and VS
every 4 hours for the first 24 hours and then PRN after that
who is in charge of setting up titrating or discontinuing optiflow/airvo systems
resp therapist or CCN not an RN
how would you calculate how long a cylinder will supply o2 to a patient
(PSI x conversion factor)/ (L/min)
This will give you how many minutes is left in the tank at that specific flow rate
what is the conversion factor for E-class tanks
0.28
what are these called
oropharyngeal airways
how long can you use a Oropharyngeal Airway
very short term
how often do you have to remove and access an oropharyngeal airway
every 8 hours
how do you measure an oropharyngeal airway
from the mouth to the angle of the jaw or from the mouth to the earlobe
if a person is using a nasopharyngeal airway how often do you have to reposition the airway to the other nare
switch nares every 8 hours
how do you measure a nasal airway
measure from the earlobe to the tip of the nostril
what are the three components of a trach tube
Outer canula
inner canula
obturator
when caring for a patient with a chest tube what additional equipment should be at the bedside
-Two clamps
-Sterile dressing
-tape
-Bottle of sterile water
where would a chest tube be inserted if someone had fluid in the pleural space
lower chest since the fluid would sit in the bottom of the pleural space
where would a chest tube be inserted for a pneumothorax
in the upper chest since that is where the air would collect
what is an empyema
when pus builds up in the pleural space
what would you do if chest tube becomes disconnected from the drainage system
-clamp tube
-submerge in 2cm of sterile water
-clean ends and reconnect
-un clamp
what would you do if a chest tube is pulled out of the patient
-cover site with sterile gauze and tape
-leave one side un taped so air can get out but not get back in
is it ever safe to try and milk the chest tube to get clots out
no causes a lot of pressure inside the pleural space
should you ever recap a used needle
NO should only cover it with a safety device
when should a sharps container be changed
when it is 2/3 full
how much liquid is typically injected intra dermally
usually only 0.1 mL
what should a syringe be labeled with if it has medication in it
-2 client identifiers
-name of med
-dose
what is the most common site for an ID injection
inner forearm or anywhere there is not a lot of sub q tissue
when administering an ID injection the needle should be inserted at what angle
should be inserted at 5-15 degrees
how far should you insert the needle into the patient
about 3mm into the skin
how long after administration is a TB skin test read
48-72 hours
how many mm is considered negative for a TB skin test
0-4 mm is considered negative
how many mm is considered positive in high risk populations for a TB skin test
5-10 mm is considered positive in high risk populations
how many mm is considered positive for all people in a TB skin test
anything over 10mm is positive for everyone
