I'm a student in Iowa and in OB now. When I get to the point of assessing vaginal or breast areas there does have to be another nurse present and I think that nurse has to be female. Also I only watch this other nurse perform these tasks while she shows me what to look for.
What does your school do about female caths? I haven't come across this yet but I am pretty sure they wouldn't let me do it. Basically they say if I need to know it I'll learn it on the job...
