Which unit should I spend the next 2 yrs on? M/surg or tele or a year on both? I want to specialize in Critical care. i have 7 yr of LPn experience but in nsg homes. I am a new RN should I use this experience or start from scratch. I hated being a Nursing home nurse, I didnt feel like a professional at all, although the pay was irresistable but I am proof that Higher pay does not add to your professional esteem if you have no responsibility. Please Respond.
