NBCRNA BOARD REVIEW TEST
2025
Bound O2 calculation - ANSWER Pt's Hgbx1.34mL/g x O2 saturation
Dissolved O2 calculation - ANSWER PaO2 x 0.003
Dissolved CO2 in blood calculation - ANSWER PaCO2 x 0.067. Take into
account CO2 is 20 x more soluble in blood than O2 which is then multiplied by
0.003
BMI - ANSWER kg/m^2
Ejection Fraction - ANSWER (end diastolic volume- end systolic volume)/ end
diastolic volume
Significant figures - ANSWER Rule One: All non-zero digits are significant.
Rule Two: Zeroes occurring before other figures are not significant except when
they mark the end
of the number to the right of the decimal point or occur between non-zero
figures.
SVR calculation - ANSWER [(MAP-CVP)/CO]x 80 dynes*sec/cm^-5
celsius to fahrenheit - ANSWER 1.8x C+32
