Question about V/Q ... More specifically about V

BRS and FA tells me that V is maximal at the bases.

Kaplan Physio Q bank tells me V is max at the apexes.

Is there any rational reason why Kaplan would say that? Or did they simply make a mistake?

Thanks!

Kaplan is wrong. Both V and Q increase as you go towards the base, but Q more so than V -- so at the apex, V/Q = 3, but at the base, V/Q = 0.6. Kaplan may be referring to the fact that excessive V given the Q is the "problem" at the apex (why TB, an aerobe, preferentially hits upper lobes when active).
