Is the word ministra the same in Brazilian and European Portuguese?

Yes

The word "ministra" is identical in meaning, grammar, and spelling in both Brazilian and Continental Portuguese. It functions as a feminine noun (referring to a female government minister or a female religious official) and as the third-person singular present indicative of the verb ministrar (to administer, to teach, or to provide). The only difference is in pronunciation; Brazilian Portuguese typically features more open and clearly articulated vowels, while Continental Portuguese features more vowel reduction and "closed" or swallowed vowel sounds.
