Associate degree programs in nursing offer students training and skills that they can apply either in an entry-level career or in a bachelor’s degree program. Degree programs may take two years for full-time students to complete. However, many schools require incoming students to complete certain prerequisites before beginning a program, which can extend the time needed for an associate degree in nursing, or ADN.

Online Associate Degree in Nursing: Coursework and Overview

Students working toward an ADN take several prerequisites, including both nursing-related and general education classes, in addition to nursing electives. Curriculum varies by school, but the following are some courses that students commonly take:

Nursing-Related Courses

  • Fundamentals of Nursing: Courses provide an introduction to the skills and responsibilities involved in nursing practice. Specific topics may include meeting basic human needs and nursing care delivery.
  • Human Anatomy: Individuals study the structure of human body systems, including the skeletal, muscular, digestive, and reproductive systems. Courses often have a lab component through which students can gain hands-on experience.
  • Human Physiology: While anatomy courses explore the structure of human body systems, physiology courses cover their functions. Specific topics examined generally include cells, tissues, and human organ systems. Schools may combine anatomy and physiology into one course.
  • Microbiology: Courses focus on fundamental microbiology concepts such as microbial cell structure and metabolism. Students may also examine the role of microorganisms in genetics, immunity, and disease, among other topics.
  • Mental Health Nursing: Training aims to help students acquire skills in caring for mental health patients. For example, courses usually address communication and therapeutic interventions in mental health nursing.

General Education Courses

  • Sociology: Introductory courses allow students to explore the role that factors such as race, income inequality, and gender play in society.
  • English Composition: Students can strengthen their critical thinking and writing skills by analyzing literary works both in class and in essays. Nursing candidates are likely to make use of this background as they work with medical records.
  • Psychology: In introductory courses, students can gain a fundamental knowledge of various psychology concepts, commonly including cognition, personality, learning, and behavior.

Potential Careers for Individuals with an Associate Degree in Nursing

Specific responsibilities depend on the nurse’s work setting. For example, some LPNs and LVNs help deliver and care for infants, while others perform laboratory tests. Although LPN and LVN positions may not require an associate degree, they do require completion of an accredited educational program in nursing, according to

Taking a medical-surgical nursing elective, if available, can also teach students about caring for surgical patients. notes that this is one of the many ways registered nurses (RNs) can specialize.
  • Genetics nurses screen, treat, and counsel patients with a genetic disorder, such as Huntington’s disease. Biology courses such as genetics and microbiology can educate students on diseases that genetics nurses might come across. Pathophysiology courses, which discuss disease in more detail and are sometimes offered through ADN programs, may also help prepare students for caring for patients with a disease.

Advanced nursing courses in ADN programs may discuss how to care for patients in critical situations and can help students develop an understanding of this nursing specialization.
