Summary
Cervical exams can be tricky for the novice practitioner. Think about this: it’s a blind exam, we measure that distance using only two fingers, through a layer of tissue, sometimes with a patient moving up on the bed as we examine. That is the reality of a cervical exam. Intrapartum, some nursing staff and clinicians use qualitative descriptors like "a tight 4" or "a generous 5" to convey nuance. In line with this, some report cervical examinations in “half- centimeters”. This sounds like this: “well, her last cervical exam was 5cm but now she is 5 and a half”. Is that a thing?
