You only can travel to Italy or transit through other Schengen countries for up to 5 days in order to reach your final destination which is Italy based on your visa.
You can’t travel to other Schengen countries if your citizenship requires to have a visa for Europe, as a student you have gotten a national type D visa valid for “Italia” and you need to get your residence permit [Carta/Permesso di soggiorno] to travel to the other Schengen countries.

You only can travel to other Schengen countries legally if you hold a passport that does not require a visa for the Schengen zone as tourist or for business, before you have gotten your residence permit.
