It sounds to me that if a nurse was color deficiant and knew it, that he/she could just get a second opinion on an issue/color that they were unsure of. I know of 3 different colorblind doctors and this is what they do, they just get a second opinion to be sure. They are brilliant doctors and have never caused harm due do messing up a color. I will be entering a nursing program this fall to a school that three years ago used to have in there application that you could not be colorblind and enter the program. They have since eliminated that section because they said that it was actually discrimination. The N-CLEX exam to actually get your RN license does not require a color test. It would be the place of actual employment that may screen for color blindness. I wish everyone luck!
