What nursing specialties would you recommend who is more of an introvert?

Nursing Informatics is a perfect position for that.

Home Infusion would also be a good option - you have 1;1 patient ratio, you do need to know how to interface with family as well, and of course you'll need excellent IV placement and central line care experiences/skills.

All of them. I am a Scorpio introvert. No problems. I am at work to care for patients, not socialize.

Research or Informatics

Forensic nursing, legal nursing consultant and informatics are truly the best for any introvert. There is also case management or insurance review nursing.
