RNs must have extensive knowledge in the hard sciences and math. Most nursing programs require student nurses to take classes in subjects such as chemistry, biology, statistics, physics and human anatomy.
Classes are designed to provide students with a well-rounded understanding of the reasoning behind many medical procedures. Students who have studied organic chemistry can apply this knowledge to calculate medication dosages and thus ensure that a small child does not receive the same amount as a grown man. Knowledge of human anatomy can help nurses describe exactly where a patient complains of pain. An understanding of physics can help student nurses know how to ensure that an environment remains sterile during a medical procedure. RNs who know how medications are studied can help patients decide which medication is appropriate for their condition.
In addition to hard science classes, nurses must take classes in the liberal arts and sciences. Many nursing programs allow nurses leeway in deciding which classes to take. A student RN may take classes in a variety of fields, including political science, art history, film production, English literature and philosophy.
Taking liberal arts classes can help nurses become better at their jobs when they graduate. An RN who understands how to communicate better in writing with her patients is an RN who can be more effective at her job. A registered nurse who shares an understanding of her patient's preferences in music, art and books can help patients cope better with treatment by finding them books or movies that they enjoy.
Once an RN has completed her coursework in the liberal arts and in the hard sciences, she must complete a term of education known as clinicals. During this time, she will work full time in a hospital setting under the supervision of a nursing instructor. Clinical nursing education involves direct patient care. Student nurses learn how to administer medication, supervise patients during the post-operative care period, and perform essential nursing tasks. Students must be in attendance full time. Most nursing schools require RNs to complete at least one semester of clinical coursework.
