I work in a small town, Community Health currently, and in an ER before that. I have a tattoo on my shoulder, and patients never saw it, however we had a tech that had tattoos on the backs of her hands, a respiratory therapist with peace and lover on the tops of his knuckles, two radiology techs and one RN with tribal style arm bands that always show below their sleeve line. I dont think that in this day and age of healthcare professional shortages that facilities can afford to be that picky. If you are licensed, can do a good job at patient care, they need you, regardless of how much ink you have.
That being said... nursing schools are a different story. The way the students look does reflect on the clinical program and the school that they are attending. Because they are PROVIDING you a service (by educating you) they can afford to be more demanding. Worst case scenerio, you will probably have to wear a long sleeve t-shirt under your scrub top. yes, there are several make-ups that you can use, but i would not recommend them in a clinical setting. with the amount of times you will be washing your hands, and at times up to your elbows, the make-up is not practical. Even if it the label says it is waterproof, it will fade during the day. It, is also fairly expensive to do your whole arms with every day.
Follow the rules to the best of your ability, get through school, and then I doubt that you will have any problems in the workforce.
Good Luck, Brandy
