FCCS Post Test Review Exams
Questions With All Correct Answers !!
Most important indicator that a patient has a severe illness? - Correct Answers--
Tachypnea
3 respiratory types, and their criteria - Correct Answers-- Hypoxemic (PaO2 <50-60)
Hypercapnic (PaCO2 >50, pH <7.36)
Mixed
Delta gap (formula, when and why it's used) - Correct Answers-- 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 Answers-- 1.5[HCO3] + 8 +/- 2
If compensation is adequate in acid/base issues
How AG changes with albumin changes - Correct Answers-- Decreases 2.5-3 for every
1 decrease in albumin
Hemodynamic changes after intubation - Correct Answers-- Hypo/hypertension
Arrhythmia
Tachycardia
Pressure support equation for BiPAP - Correct Answers-- IPAP - EPAP
3 types of vent cycles - Correct Answers-- 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 Answers-- 10 cc/kg
Goal FiO2 on vent - Correct Answers-- Start at 1.0, then decrease as SpO2 tolerates
(goal of 92-94 saturation)
Ppeak - Correct Answers-- Peak inspiratory pressure
