FP-C Equations & Formulas
Question 1: Original PO2 given barometric pressure O2
Concentration (0.21) x Barometric pressure Sea level=760 torr
CORRECT ANSWER : 0.21 x 760 = 159 torr
Question 2: Percentage of O2 required at higher altitudes (i.e. if
my FiO2 is 0.3 at 10,000 feet, what do I need to increase my FiO2 to at 20,000?) (%FiO2 x Current barometric pressure) / New barometric pressure CORRECT ANSWER : 10,000-20,000 feet: (0.3 x 523) / 349 = 0.44 (New FiO2)
Question 3: Potential PO2 FiO2 x 5 = Potential FiO2
CORRECT ANSWER : 0.21 x 5 = 105 (Normal)
Question 4: PaO2/FiO2 Ratio Ratio of arterial oxygen partial
pressure to fractional inspired oxygen
CORRECT ANSWER : Used to distinguish ARDS severity

Question 6: ETT depth
CORRECT ANSWER : 3x tube size
Question 7: Suction/NG/Foley size
CORRECT ANSWER : 2x ETT size
Question 8: Chest tube size
CORRECT ANSWER : 4x ETT size
Question 9: Fluid Resuscitation-Neonate
CORRECT ANSWER : 10mL/Kg
Question 10: Fluid Resuscitation-Pediatric
CORRECT ANSWER : 20mL/Kg
Question 11: Fluid Resuscitation-Adult
CORRECT ANSWER : 30mL/Kg
Question 12: Fluid Maintenance-Pediatric
- | Page
CORRECT ANSWER : 4-2-1 rule
1-10 kg --> 4mL/Kg (For the first 10kg) 2-20 kg --> 2mL/Kg (For the second 10kg) >20 kg --> 1mL/Kg (For every Kg above 20)
So, for a 30 kg child, maintenance fluid rate would be:
40 ml/hr + 20 ml/hr + 10 ml/hr = 70 ml/hr
Question 13: Blood administration-Universal donor
CORRECT ANSWER : O Negative
Question 14: Blood administration-Universal recipient
CORRECT ANSWER : AB
Question 15: Parkland burn formula

1/2 in the first 8 hours 1/2 in the next 16 hours
Question 16: Universal or "Consensus" burn formula
CORRECT ANSWER : 2-4mL x weight in kg x TBSA burned
- | Page
1/2 in the first 8 hours 1/2 in the next 16 hours
Question 17: Rule of "Nines" for burn surface area calculation
CORRECT ANSWER : Rule of "Nines" for burn surface area
calculation
