NURS 5355 Final Exam Questions and Correct
Answers
determine difficult intubation with?
✓ ~~~ LEMONS
size of tongue to oral cavity?
✓ ~~~ Mallampati Classification Score
absolute CI in endotracheal intubation?
✓ ~~~ total upper airway obstruction or loss of oropharyngeal landmarks from trauma
or burns
pressure on cricoid cartilage to compress esophagus to prevent regurg during
intubation?
✓ ~~~ Sellick's Maneuver
insert blade with ? hand on ? of the mouth?
✓ ~~~ left hand & on right side of the mouth to displace tongue to the left
aligns the oral, pharyngeal, and laryngeal axes?
✓ ~~~ sniffing position for intubation
goal of preoxygenation?
, ✓ ~~~ maximize arterial PaO2 & denitrogenation of functional residual capacity
maximizes time for intubation w/o O2 desaturation (7-9 min in healthy adult)
Room Air is?
✓ ~~~ primarily 21% oxygen and 78% nitrogen
rapid onset and short duration paralytic?
✓ ~~~ Succinylcholine: 30-45 sec; 5-10 mins
Increases K levels
rescue breaths during CPR?
✓ ~~~ less important; interrupts chest compressions and increases intrathoracic
pressure
see base of the uvula?
✓ ~~~ Class III Mallampati
soft palate not visible?
✓ ~~~ Class IV Mallampati
difficult BVM ventilation?
✓ ~~~ MOANS
oxygenation versus ventilation?
, ✓ ~~~ O2 to blood and tissues versus air in and out of the lungs
precludes apneic patient requiring crash airway?
✓ ~~~ RSI
steps to RSI?
✓ ~~~ prepare, assess (LEMONS) & preoxygenate (MOANS), medications
Crash intubation?
✓ ~~~ no RSI in unconscious or apneic patient due to cardiac arrest
occurs with inspiratory effort- inspiratory stridor?
✓ ~~~ Laryngospasm- forced glottic closure but with inspiration
induce amnesia, reduces autonomic reflex activity, no analgesia?
✓ ~~~ Sedatives
Mimics Acetylcholine? (depolarizing)
✓ ~~~ Succinylcholine- allows sodium to rush in and potassium out
reversal for Roc & Vec (non-depolarizing)?
✓ ~~~ Neostigmine (anticholinesterase)
ETT ? into trachea and ? above carina?
