Final answer:
Persistent headache should be reported as a potential pregnancy complication. Braxton Hicks contractions, mild ankle edema, and increased fetal movement are generally normal during pregnancy.
Step-by-step explanation:
The nurse should include persistent headache as a manifestation of potential pregnancy complications that should be reported to the provider. Headaches during pregnancy can be a sign of conditions such as preeclampsia or gestational hypertension, which can be serious if left untreated.
Braxton Hicks contractions and mild ankle edema are normal during pregnancy and do not typically indicate a complication. Increased fetal movement is also considered normal and may not necessarily be a cause for concern.
