PRETEST FCCS REVIEW CERTIFICATION
EXAMINATION TEST 2026 FULL ANSWERS
GRADED A+
◉ 3 respiratory types, and their criteria. Answer: Hypoxemic (PaO2
<50-60)
Hypercapnic (PaCO2 >50, pH <7.36)
Mixed
◉ Delta gap (formula, when and why it's used). 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). Answer: 1.5[HCO3] +
8 +/- 2
If compensation is adequate in acid/base issues
, ◉ How AG changes with albumin changes. Answer: Decreases 2.5-3 for
every 1 decrease in albumin
◉ Hemodynamic changes after intubation. Answer: Hypo/hypertension
Arrhythmia
Tachycardia
◉ Pressure support equation for BiPAP. Answer: IPAP - EPAP
◉ 3 types of vent cycles. 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. Answer: 10 cc/kg
◉ Goal FiO2 on vent. Answer: Start at 1.0, then decrease as SpO2
tolerates (goal of 92-94 saturation)
◉ Ppeak. Answer: Peak inspiratory pressure
◉ Pplat (try to keep it below ?). Answer: Inspiratory plateau pressure
(shows alveolar distention)
