FCCS Post Test Newest 2026/2027 Questions
and Correct Detailed Answers Already Graded
A+
Most important indicator that a patient has a severe illness? - CORRECT
ANSWER-Tachypnea
3 respiratory types, and their criteria - CORRECT ANSWER-Hypoxemic (PaO2
<50-60)
Hypercapnic (PaCO2 >50, pH <7.36)
Mixed
Delta gap (formula, when and why it's used) - CORRECT ANSWER-Difference in
AG from normal - Difference in HCO3 from normal
In AG metabolic acidosis it's used. It tells you if there's underlying metabolic
alkalosis or respiratory acidosis with bicarb compensation IN ADDITION to the AG
metabolic acidosis. Both of those would result in a high bicarb to begin with, and
a smaller change in bicarb from normal.
, Winter's formula (equation, what it measures) - CORRECT ANSWER-1.5[HCO3]
+ 8 +/- 2
If compensation is adequate in acid/base issues
How AG changes with albumin changes - CORRECT ANSWER-Decreases 2.5-3
for every 1 decrease in albumin
Hemodynamic changes after intubation - CORRECT ANSWER-
Hypo/hypertension
Arrhythmia
Tachycardia
Pressure support equation for BiPAP - CORRECT ANSWER-IPAP - EPAP
3 types of vent cycles - CORRECT ANSWER-Volume (preset tidal volume,
relieves WOB the most)
Time (constant pressure of time)
Flow (constant pressure until inspiratory flow is below 25% of peak)
Goal tidal volume - CORRECT ANSWER-10 cc/kg
