Squamous Cell Carcinoma. This nonmelanoma skin cancer may appear as a firm red nodule, a scaly growth that bleeds or develops a crust, or a sore that doesn't heal. It most often occurs on the nose, forehead, ears, lower lip, hands, and other sun-exposed areas of the body. Squamous cell carcinoma is curable if caught and treated early.
The hard skills are the hands-on procedural skills that a typical bedside nurse must use to perform the job effectively, while soft skills are the intangible interpersonal skills one needs to facilitate communication and navigate the workplace successfully.
So yes, there are a lot of potentially difficult science courses, depending on your ability, your motivation, and your background. But you don't need more than algebra, and many nurses seem to manage just fine forgetting much of the theory they have learned. There is room for the nurse who just follows instructions, but there is also a great need for nurses who can function on the fly and in a crisis, and they usually need to retain more of the background they so laboriously leaned (think ICU, OR, ER, Labor and Delivery, PAR).
