Advanced Concepts of Nursing FINALQUESTIONS & ANSWERS.
Atmospheric air contains ________% oxygen ANS - 21%
hazards of oxygen therapy ANS - COMBUSTION
-no smoking, turn it off, gas stoves are no, frayed wires
TOXICITY
-take it off if not needed (look for options to decrease oxygen at all times)
INFECTION
-change tubing by recommendations of manufacturer
DRY MUCOUS MEMBRANES
*any oxygen therapy over 4 Liters should have humidification attached*
-scarring
low flow oxygen systems ANS - nasal cannula
-24-44% oxygen delivered
-1-6 L
high flow nasal cannula
-15 L per min, green, durable
simple face mask
-40-60% O2
-5-8 L per min
,partial rebreather mask
-take in some oxygen and some room air
-40-75% O2
-6-11 L per min with one one-way-valve
nonrebreather mask
-makes patients anxious
-80-95% O2
-10-15 L per min
-must fit snug
-no breathing in room air
nasal cannula flow rate ANS - 1-6 L/min
*anything greater than 4 L/minute requires humidification*
Nasal cannula oxygen concentration ANS - 24-44%
nasal cannula nursing interventions ANS - - ensure prongs are in the nares properly
- apply water-soluble jelly to nares as needed
- assess patency of nostrils
- assess the patient for changes in RR rate and depth
- provide humidification for flow rates >4L/minute
,high flow nasal cannula flow rate ANS - 15 L/minute
Simple face mask flow rate ANS - 5-8 L/min
simple face mask for oxygen delivers an FiO2 of ___ to ___ % ANS - 40-60%
simple face mask nursing interventions ANS - - be sure that the mask fits securely over nose and mouth
- assess skin and provide skin care to the area covered by mask d/t moisture under mask
- flow rates less than 5 Liters can result in rebreathing of C02
- monitor the patient closely for risk for aspiration
- suggest to the HCP to switch the patient from mask to the nasal cannula during eating
- can cause anxiety and claustrophobia
- eating, drinking, talking impaired
partial rebreather mask flow rate ANS - 6-11 L/min
partial rebreather mask for oxygen delivers an FiO2 of ___ to ___ % ANS - 40-75%
partial rebreather mask nursing implications ANS - - the reservoir bag attached with no valve allows the
client to rebreathe up to 1/3 of exhaled air together with room air
- complete deflation of the reservoir bag during inspiration causes C02 build-up (keep bag inflated by
INCREASING flow rate)
, - assess skin breakdown
- ensure that the client uses a nasal cannula during meals
- make sure the reservoir doesn't twist or kink
non-rebreather mask flow rate ANS - 10-15 L/min
non-rebreather mask for oxygen delivers an FiO2 of ___ to ___ % ANS - 80-95%
- delivers the highest 02 concentration possible (except for intubation)
- the one-way valve situated between the mask and reservoir allows the client to inhale maximum 02
from covering them that prevent room air from entering the mask
non-rebreather mask nursing implications ANS - - perform hourly assessment of valve and flap
- closely assess
- assess proper fit over nose and mouth
- nasal cannula during meals
how do we fill a bag with a rebreather mask ANS - increase flow rate until bag fills then put on
*if bag is partially full then increase flow rate*
problems with face masks ANS - aspiration
