EBN Twitter Journal Club – Session Two

We all know that exposure to tobacco smoke during pregnancy can have negative effects on both maternal and child health. Yet, we haven’t had an understanding of all specific effects until now.  The study under review this week gives nurses insight into this important public health issue and has the potential to influence nursing care of women and families during pregnancy.

Our discussion will take place from Thursday, January 31 to Friday, February 4th.  To participate, simply tweet using #ebnjc.
