Are you talking about female or male nidoran? In what Pokemon they evolve, it depends on what nidoran you catch(since the two nidorans are different). First of all, both male and female nidoran evolves, at level 16(). Both of them evolves to Nidorin@. Euh, now comes the thing that you need to remember- when either male or female nidoran evolves, you need to give ti a moon stone to get its last evolved form- if you give it to Nidorin@, you will get either Nidoking or Nidoqueen, depending on Nidorin@'s gender.
Both sexes of Nidoran evolve at level 16. Males evolve into Nidorino and females evolve into Nidorina.
At level 16, it should evolve into a Nidorino, and then, give it a moonstone to evolve it into a Nidoqueen.
Nidorino does not evolve naturally in any Pokemon game. Instead, he must be evolved with a Moon Stone. They can be found throughout the game (first one is in Mt. Moon). Best not to use it until he learned Horn Drill at level 53 though.
There is a store where you can buy moonstones, use that.
