In the early stage of a PE, what would ABG results probably
indicate? - correct answer -resp. alkalosis ( due to
hyperventilation)

pain. Assessment findings include: diaphoresis, hypotension,
crackles in left lower lobe, and pulse ox of 85%. What does the
nurse suspect has occurred with this patient?
a) atelectasis
b) pneumothorax
c) PE
d) flail chest - correct answer -c (PE)
Because the patient with PEEP is at risk for *tension
pneumothorax*, what is the nurse's priority action?
a) assess lung sounds q 30-60 min
, Page | 2
b) obtain order for ABG
c) have chest tube equipment on standby

A pt on mechanical ventilation is beginning to take spontaneous
breaths at his own rate & TV between set ventilator breaths.
Which mode is the ventilator on? - correct answer -SIMV

answer -*hypo = resp. acidosis (low pH, high CO2, high K+)*
ex:
-resp. depression (drugs)
-impaired breathing/chest expansion/obstruction
-*ARDS*, pulm edema, etc.

*hyper = resp. alkalosis (high pH, low CO2, low K+)*
ex:
-hyperventilation (fear, anxiety, pain)
-*mechanical ventilation*
-shock
-*early stage* of acute resp. prob (*early PE*)
True or False:
Patients with chest tubes should be encouraged to TCDB, attempt
maximum inhalations, and use ICS - correct answer -true
True or False:
