NUR 256 Exam 2 UPDATED ACTUAL Questions and CORRECT Answers
RESPIRATORY
1-6 L/min
24-44%
-advantages: safe and simple, easily tolerated,
does not impede eating or drinking
nasal cannula -disadvantages: drying to mucus membranes,
dislodges easily, breakdown on ears/nares,
patients breathing pattern effects FiO2 (mouth
breathing)
-need to asses skin breakdown
6-12 L/min
35-50%
-Advantages: useful for short period of time
simple face mask
-disadvantages: claustrophobia, interferes with
eating and drinking, increased risk of aspirations
-need to asses skin break down
10-15 L/min
60-90%
-advantages: delivers increased FiO2, does not dry
Partial and Nonbreather masks mucus membranes
-disadvantages: interrupts eating and drinking, bag
should not deflate, can lead to CO2 retention
-used when trach is removed
24-50%
-advantages: provide a specific amount of oxygen
venturi mask
-disadvantages: interrupts eating and drinking,
specific flow rates must be followed
, adjustable FiO2 up to 60L/min
-advantages: can be used on adults and children
High flow nasal cannula
-disadvantages: FiO2 dependent on patient
respiratory pattern
what face mask would you use for nasal cannula
someone with COPD? -it is very hard to move back to the less oxygen masks after you have moved up
21-100%
-advantages: avoids the use of artificial airways
noninvasive ventilation
-disadvantages: claustrophobia, mask can cause
skin breakdown
device that uses least amount of O2 nasal cannula
device that uses most amount of O2 non-rebreather
at what FiO2 do you need to use 4 liters
humidification
coughing technique used to help cough up mucus effectively without making you
feel too tired
Huff cough
-inhale through mouth slightly deeper than normal
-activate stomach muscles and blow air out in three breaths while making hah ha ha
sounds
helps to retrain this muscle to work more effectively, enhances your diaphgram
ability to release air
Diaphgramatic breathing -put one hand on chest and one on stomach
-deep breath in for 2 seconds feeling stomach moving outward (doing activity
correctly if stomach is moving more than chest)
purse your lips and breath out slowly through mouth
make sure to compare right and left lungs when
auscultating and palpating
respiratory assessment
reduces how hard you have to breath, helps
release air trapped in lungs, promotes relaxation,
reduces shortness of breath
-while keeping mouth closed take a deep breath in
pursed lip breathing
through nose counting to 2
-purse your lips together as if you are starting to
whistle
-while lips are pursed slowly breath outward
counting to 4 (don't force air out)
-encourages voluntary deep breathing
-patient inhale on device
incentive spirometry -goal is based on pts age, sex, and height
-should be preformed 5-10 times every hour while awake
-only nurse can teach (aids cannot)
helps to remove mucus from the airways by using
vibrations and positive pressure
acapella
-patient blows into device
