Pelvic Exam Question

I posted this question on the NP forum and only got one answer. While that was appreciated, I hoped for more! Anyone on this forum have an answer?

I'm an experienced FNP, have done many pelvic exams, rarely have to repeat a pap for a bad specimen. I do an average of 1-2 a day.

I also try to give as gentle a pelvic exam as possible.

However, on occasion, not often, I have a problem. I can get the cervix into the ends of the speculum, but then when I'm done, I can't get the speculum to "let go" of the cervix, no matter what I do.

I get frustrated and of course it's uncomfortable if not outright painful for the patient.

I hate this- I wouldn't want that to happen to me as a patient- but I can't figure out what I'm doing wrong!! Help!

I use the disposable plastic speculum with the light in the handle, if that makes any difference. I usually use a medium but will use a small or a large if necessary. It probably happens with all sizes.

Thanks so much for any and all responses!
