The perinatal nurse notes a rapid decrease in the fetal heart rate (FHR) that does not recover ...

ANS: C
The nurse needs to assess the fetal heart rate immediately before and after the artificial rupture of the membranes. Changes such as transient fetal tachycardia may occur and are common. However, other fetal heart rate patterns, such as bradycardia and variable decelerations, may be indicative of cord compression or prolapse. The nurse should perform a vaginal examination to assess for cord prolapse. Administering oxygen may or may not be needed. Maternal temperature is assessed every 2 hours after artificial rupture of membranes but is not related to this situation. The nurse should not wait 30 minutes prior to doing anything.

I know this sounds cliche, but I was thinking the same thing. Thanks for confirming
