Ok, I have a problem.  My AP2 teacher ran out of power point to
lecture and one and a half hours to kill so she told us to get out the
tables.  We just got finished with the vans and arteries so she told
us to massage the vans and arteries to increase there blood flow.  I
remembered 1. in basic they said not to massage the vans and arteries
and 2 It could cous stroke and 3 a nursing supervisor said that
simulating the caratic artery could cause heart arithmea.  I stood up
and told her what the nursing supervisor said.  She countered with you
can push on the carotic artery for one and a half minet if you only do
one side at a time.  I didn't massage and vans or arteries but my
classmates did.

Is my teacher incompetent or am I over worrying?
