FCCN Level 2 Exam 2026 Questions and
Answers
PaO2 - Correct answer-partial pressure of oxygen in arterial blood, obtained using
an ABG
80-100mmHG
PaO2 60=SpO2 90%
SpO2 - Correct answer-saturation of peripheral oxygen, obtained using pulse ox
90-100%
SpO2 90%=PaO2 60
PaCO2 - Correct answer-35-45

,respiratory acidosis - Correct answer-low pH, high CO2
causes: CNS depression from drugs such as sedation, injury, or disease
breathe too slow, retaining CO2
respiratory alkalosis - Correct answer-high pH, low CO2
causes: pain, fever, sepsis
breathe too fast, not retaining enough CO2
HCO3 - Correct answer-22-26
metabolic acidosis - Correct answer-low pH, low HCO3
causes: diarrhea, DKA, hyperkalemia
metabolic alkalosis - Correct answer-high pH, high HCO3
©COPYRIGHT 2025, ALL RIGHTS RESERVED 2
,causes: vomiting, suctioning, hypokalemia
pH - Correct answer-7.35-7.45
reading ABGs - Correct answer-1. evaluate pH to identify acidosis or alkalosis
2. match CO2 or HCO3 with pH state using ROME to determine respiratory or
metabolic
3. assess whether CO2 or HCO3 state is opposite of pH to determine if it is
uncompensated, partially compensated, fully compensated, or corrected
non-invasive ventilation - Correct answer-CPAP/BiPAP
CPAP - Correct answer-continuous positive airway pressure; provides inspiratory
pressure
BiPAP - Correct answer-bilevel positive airway pressure; provides inspiratory and
expiratory pressure
intubation - Correct answer-insertion of ETT into trachea
RSI - Correct answer-administration of induction agent and neuromuscular
blockade agent simultaneously
intubation kit medications - Correct answer-premeds - versed and fentanyl
©COPYRIGHT 2025, ALL RIGHTS RESERVED 3
, sedatives - propofol, etomidate, ketamine
paralytics - succinylcholine, rocuronium
pressor - phenylephrine
intubation preparation - Correct answer--notify RT and pharmacist
-discuss need for intubation and obtain consent, ensure pt does not have DNI order.
-evaluate whether pt has difficult airway
-verify equipment and PPE
-assure functioning IV access
-position pt
-ensure verbalization of procedural pause
-preoxygenate
RN role during intubation - Correct answer-monitor pt vital signs especially O2
sats, administer medications, monitor time of intubation attempts, suctioning as
needed
