Question 4Select one:

a.Functional residual capacity (FRC)

b.Inspiratory capacity (IC)

c.Residual volume (RV)

d.Total lung capacity (TLC)

e.Vital capacity (VC)

a.Functional residual capacity (FRC)

What changes to forced vital capacity (FVC) and FEV₁/FVC ratio compared to predicted are consistent with a restrictive pattern on spirometry? 

Question 11Select one:

a.Both FVC and FEV₁/FVC ratio are increased 

b.Both FVC and FEV1/FVC ratio are reduced 

c.FVC is increased, FEV₁/FVC ratio is reduced

d.FVC is reduced, FEV₁/FVC ratio is normal or increased

e.FVC is normal, FEV₁/FVC ratio is reduced 

FVC is reduced, FEV₁/FVC ratio is normal or increased
