Learn Arabic (Modern Standard): هي ممرضة هناك.

In Arabic, there is no present tense verb for 'to be' (am, is, are). You simply place the independent pronoun هي (she) right next to the noun ممرضة (nurse) to mean 'She is a nurse'.

How do I pronounce the pronoun هي?

It is pronounced 'hiya' (sounding a bit like the English phrase 'see ya'). It is the standard subject pronoun used for 'she'.

Why does ممرضة end with the letter ة?

The letter ة (taa marbuta) is a common feminine marker. Because the subject pronoun is هي (she), the noun describing her must also be feminine. If we changed the pronoun to هو (he), the noun would drop the ة and become ممرض (male nurse).

Wait, doesn't هناك mean 'there is'?

It can! The word هناك is very flexible. Sometimes it means 'there is' or 'there are', but at the end of a sentence like this, it simply refers to a location: 'over there'.
