Question 1 of 5
Which of the following would be a contraindication to use an HME on a mechanically ventilated patient?

Question 3 of 5
Calculate the functional residual capacity (FRC) from the following results: TLC=5750 ml, IRV=3000 ml, Vt=500 ml, RV 1200 ml
Correct Answer: D
Rationale: FRC = RV + ERV. Since ERV isn't given, FRC = TLC - (IRV + Vt) = 5750 - (3000 + 500) = 2250 ml.
Question 4 of 5
What method can be used to identify a virus?
Correct Answer: D
