FCCN Level 2 UPDATED Actual Exam
Questions and CORRECT 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
metabolic alkalosis - CORRECT ANSWER✔✔- high pH, high HCO3
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
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
intubation process - CORRECT ANSWER✔✔- -following sedation, bag mask ventilate the
pt
-physician visualize ETT passing through cords
-anesthesia backup will be notified after 10 minutes or 2 attempts to secure the airway
post intubation care - CORRECT ANSWER✔✔- -portable chest x-ray, ABGs
-obtain sedation and analgesia orders
-hourly RASS observation
-monitor for hemodynamic changes
FiO2 - CORRECT ANSWER✔✔- fraction of inspired oxygen; the concentration of oxygen
in the air we breathe
RA is 21%, maximum is 100%
lung protection FiO2 goal: maintain SpO2 target with FiO2 <60%
PEEP - CORRECT ANSWER✔✔- positive end-expiratory pressure, provides positive
pressure to airways during expiration and helps keep alveoli open
common mechanical ventilator setting in which airway pressure is maintained above
atmospheric pressure
disadvantages: increased thoracic pressure decreases venous return to the heart. high levels
can cause barotrauma, tension pneumo
respiratory rate - CORRECT ANSWER✔✔- minimum number of breaths per minute the
vent will ensure your pt takes
increase the rate to blow off CO2, decrease rate to retain
tidal volume - CORRECT ANSWER✔✔- amount of air that moves in and out of the lungs
during a breath. calculated based on predicted body weight (height and gender)
6mL/kg is ideal
minute ventilation - CORRECT ANSWER✔✔- tidal volume x respiratory rate
