Dosimetrist Career Guide: Role, Salary, Education, and How to Get Started
11 Apr, 2026
If you've been searching for comprehensive registered nurse information, you've come to the right place. I've spent years helping healthcare professionals navigate their career paths at healthcareers.app, and I can tell you that nursing remains one of the most rewarding, in-demand, and versatile careers in the entire healthcare ecosystem. Whether you're a high school student exploring your options, a career changer looking for stability and purpose, or a working professional curious about adjacent healthcare fields, this guide will give you the detailed, actionable information you need to make confident decisions about your future.
At healthcareers.app, we built our platform because we believe every healthcare professional deserves clear, honest guidance — and registered nursing is consistently one of the most searched career paths on our site. Let me walk you through everything from education requirements and licensure to salary expectations, specialization opportunities, and even how the nursing profession intersects with fascinating fields like forensic biology and optometry.
A registered nurse (RN) is a licensed healthcare professional who provides direct patient care, coordinates treatment plans, educates patients and families about health conditions, and serves as a critical link between patients and physicians. RNs work in hospitals, clinics, long-term care facilities, schools, corporate settings, home health agencies, and many other environments.
According to the Bureau of Labor Statistics (bls.gov), there were approximately 3.2 million registered nursing jobs in the United States as of their most recent occupational outlook data. The profession is projected to grow by 6% from 2022 to 2032, which translates to roughly 177,400 new job openings each year when accounting for retirements and workforce transitions. That growth rate is faster than the average for all occupations, making nursing a remarkably stable career choice.
One of the most important pieces of registered nurse information that I share with aspiring nurses is this: there are multiple educational pathways to enter the profession, and the right one for you depends on your timeline, budget, and long-term career goals.
The ADN is typically a two-year program offered at community colleges and some vocational schools. It's the fastest and most affordable route to becoming an RN. Graduates are eligible to sit for the NCLEX-RN licensure exam, and many hospitals hire ADN-prepared nurses — though some larger health systems now prefer or require a bachelor's degree.
The BSN is a four-year degree offered at universities and colleges. It provides a more comprehensive education that includes public health, nursing research, leadership, and community health. According to the American Association of Colleges of Nursing (aacnnursing.org), the BSN is increasingly considered the standard for professional nursing practice, and many employers offer tuition reimbursement for ADN nurses pursuing their BSN.
If you already hold a bachelor's degree in another field, accelerated BSN programs allow you to complete your nursing education in 12 to 18 months. I've worked with many career changers on our platform who've taken this route, and they consistently tell me it's intense but incredibly rewarding.
Regardless of which educational path you choose, every aspiring RN must pass the National Council Licensure Examination for Registered Nurses (NCLEX-RN). This standardized exam tests your clinical knowledge, critical thinking, and ability to provide safe, effective care. Each state's board of nursing administers licensure, and requirements can vary slightly by state — so I always recommend checking your state board's specific guidelines.
When people come to healthcareers.app looking for registered nurse information, salary is almost always near the top of their question list — and I completely understand why. You want to know that your investment in education and training will pay off.
According to the Bureau of Labor Statistics, the median annual wage for registered nurses was approximately $81,220 as of May 2023. However, salaries vary significantly based on geography, specialty, experience, and work setting:
Travel nursing has also emerged as a lucrative option, with many travel RN contracts offering weekly pay rates that far exceed local staff nurse wages — though these rates have normalized somewhat since the pandemic peak.
One of the aspects of the nursing profession that I find most exciting is the incredible range of specializations available. Once you've earned your RN license and gained some clinical experience, you can pursue certifications in dozens of specialized areas.
Many RNs go on to pursue advanced degrees that open doors to roles such as Nurse Practitioner (NP), Certified Registered Nurse Anesthetist (CRNA), Clinical Nurse Specialist (CNS), or Certified Nurse Midwife (CNM). These roles require a Master of Science in Nursing (MSN) or a Doctor of Nursing Practice (DNP) and often come with significantly higher salaries and greater autonomy in patient care.
Here's something I find genuinely fascinating that many aspiring nurses don't consider: the intersection of nursing with forensic biology. Forensic nursing is a growing specialty that combines clinical nursing skills with the principles of forensic science, including forensic biology — the study of biological evidence as it relates to legal investigations.
Forensic nurses, particularly Sexual Assault Nurse Examiners (SANEs) and forensic nurse investigators, are trained to collect biological evidence, document injuries for legal proceedings, and provide expert testimony in court. Their work sits at the crossroads of healthcare and the justice system, requiring knowledge of DNA evidence collection, wound pattern analysis, and chain-of-custody protocols — all concepts rooted in forensic biology.
According to the National Institutes of Health (nih.gov), forensic nursing has been recognized as a vital subspecialty that improves both patient outcomes and the quality of evidence used in criminal proceedings. If you're drawn to both nursing and the investigative sciences, this niche offers a compelling career path that directly applies forensic biology principles within a healthcare framework.
In my experience at healthcareers.app, many people researching nursing careers are also exploring other healthcare professions to find the best fit. One field I'm frequently asked about is optometry, so let me share some clarity on the education requirements for an optometrist and how this path compares to nursing.
Optometrists are healthcare providers who examine eyes, diagnose vision problems and eye diseases, prescribe corrective lenses, and in many states, treat certain eye conditions with medications. The educational path is quite different from nursing:
The Bureau of Labor Statistics reports that optometrists earned a median annual salary of approximately $125,590 and that the profession is projected to grow by 9% from 2022 to 2032. It's a fantastic career, but the time and financial investment is considerably greater than the nursing pathway — so it's important to weigh your priorities carefully.
After connecting with thousands of nurses through our platform, I've gathered insights that can help you start strong. Here are my top recommendations:
The timeline depends on your educational path. An Associate Degree in Nursing (ADN) takes approximately two years, while a Bachelor of Science in Nursing (BSN) typically takes four years. Accelerated BSN programs for those with a prior bachelor's degree can be completed in 12 to 18 months. After completing your degree, you'll need to pass the NCLEX-RN exam before you can practice.
A registered nurse holds either an ADN or BSN and provides direct patient care under physician oversight. A nurse practitioner (NP) holds a graduate degree — either a Master of Science in Nursing (MSN) or a Doctor of Nursing Practice (DNP) — and has expanded scope of practice, including the ability to diagnose conditions, prescribe medications, and in many states, practice independently without physician supervision. NPs also typically earn higher salaries.
Yes, absolutely. Forensic nursing is a recognized specialty that applies principles of forensic biology to clinical practice. Forensic nurses collect biological evidence, document injuries for legal cases, and may provide expert testimony. This field requires additional training beyond your RN license, typically through certificate programs or graduate-level forensic nursing courses.
Based on every data point I've reviewed, nursing remains one of the strongest career choices in healthcare. The Bureau of Labor Statistics projects consistent job growth, and the ongoing nursing shortage means that qualified RNs are in high demand across virtually every healthcare setting. Salaries are competitive, advancement opportunities are abundant, and the profession offers remarkable flexibility in terms of specialty, schedule, and geographic location.
The education requirements for an optometrist are significantly more extensive. Becoming an optometrist requires a bachelor's degree followed by a four-year Doctor of Optometry (OD) program, totaling at least seven to eight years of education. In contrast, you can become a registered nurse with a two-year ADN or a four-year BSN. Both are excellent healthcare careers, but they differ substantially in terms of educational investment, scope of practice, and work environment.
I hope this comprehensive guide has given you the registered nurse information you've been looking for — and perhaps opened your eyes to possibilities you hadn't previously considered, from the intriguing world of forensic biology applications in nursing to understanding how the education requirements for an optometrist stack up against the nursing pathway. The healthcare field is vast, and there's truly a place for every passion and personality within it.
