NR 341 RESPIRATORY EXAM WITH
100% CORRECT ANSWERS 2025/2026
nasal cannula correct answers >> -0.24-0.44 (24-44%) O2
-place on 1-6L do not got over
- at 4L add humidification
-if not effective switch to high flow nasal cannula or other device
high flow nasal cannula correct answers >> 0.60-0.90 (60-
90%)
1-15L, usually starts at 6L
should have humidification
Simple face mask correct answers >> 0.30-0.60 (30-60%)
6-15L
used for mouth breathers
venturi mask correct answers >> 0.24-0.50 (24-50%)
color coded
used for more specific oxygen percentage, high flow
partial nonrebreather correct answers >> 0.35-0.60 (35-60%)
10-15L
rarely used
, exhalation ports are opens
nonrebreather correct answers >> 0.60-0.80 (60-80%)
15L
must be spontaneously breathing
one way valves stay closed
bag valve mask correct answers >> 1.00 (100%)
15L
manual resuscitation bag
noninvasive positive pressure ventilation correct answers >>
aka BiPAP (sometimes just nasal, inspiratory and expiratory
pressures set ex: 15/10)
delivers forced constant pressure into airway ex: emphysema,
COPD.
CPAP: constant pressure full face mask.
nursing considerations for O2 correct answers >> 4L or
more= humidification
assess O2 stats, RR, lung sounds
monitor for O2 toxicity
mask is an aspiration risk
prior to intubation correct answers >> analgesics: morphine
sedatives: benzos, neuroleptics, Propofol
