I really like the TEAS Exam Questions app. The full app is $7 and has tons of questions and flash cards. It provides explanations for both correct and incorrect answers (so if you guessed on something and got it right, you can know WHY it's right). Well worth the purchase, and no glitches for me thus far.
Not a nurse (yet), but I bought a pair of Nurse Mates from DSW for my serving job and I absolutely LOVE them. Pricey, but very much worth it to me. You might check out a DSW store for their work shoes and see if you find some you like!
