Can I get a tattoo a week after a nose job?

It is possible to get a tattoo one week after a nose job, as long as the tattoo is not on your nose.

I wouldn't and here's why: any needle puncture can produce a mild transient bacteremia where skin flora (bacteria, etc.) end up in the bloodstream. That is usually not an issue in a healthy individual as your body's natural defenses make short work of it. In fact, in surgery we use IV antibiotics at the time of incision in anticipation of bacteremia. But what if you get your tattoo and those bacteria seed your rhinoplasty wound, and you're no longer on postoperative antibiotics after 1 week? You can end up with an infectio. Although you would probably be fine getting the tattoo now, I would be extra cautious and delay it 4-6 weeks.

I would avoid getting as tattoo until you have healed well enough from your surgery, Best of luck...
