CHAPTER 6 & 8 RCP 180 EXAM QUESTIONS AND ANSWERS
Primary goal of VC-CMV - CORRECT ANSWER✅✅achieve a VE that matches the patients metabolic
needs
VE - CORRECT ANSWER✅✅Minute ventilation
Total oxygen consumption at rest - CORRECT ANSWER✅✅250 mL/min
Total CO2 production at rest - CORRECT ANSWER✅✅200 mL/min
Minute ventilation equation - CORRECT ANSWER✅✅tidal volume x respiratory rate
ideal body weight formula for men - CORRECT ANSWER✅✅106+6 (H in inches - 60)/2.2
Ideal body weight formula for women - CORRECT ANSWER✅✅105 + 5(H in inches - 60)/2.2
After finding ideal body weight, what do you do? - CORRECT ANSWER✅✅Multiply by 6 and by 8 to get
the tidal volume range
What is the ideal VT range for infants and children - CORRECT ANSWER✅✅4 to 8 mL/kg
A patient with ARDS will have what kind of VT rate? - CORRECT ANSWER✅✅Lower VT rate (ex. 4 mL/kg
IBW)
If an ARDS/restrictive pt needs lower VT, what should we do? - CORRECT ANSWER✅✅Increase rate so
that VE(minute ventilation) is not affected
If rate needs to be decreased to avoid a COPD/asthma pt from airtrapping, what should you do? -
CORRECT ANSWER✅✅Increase VT
