What Does a Forensic Biologist Do? A Day Inside the Crime Lab
30 Jun, 2026
If you've searched for a registered nurse overview recently, you've probably encountered the same recycled information: earn your BSN, pass the NCLEX, get hired at a hospital. Repeat. But here's the thing — I've spent years working with nurses at every stage of their careers through healthcareers.app, and the profession has evolved so dramatically that the standard overview barely scratches the surface of what's actually possible for today's RNs.
The Bureau of Labor Statistics consistently ranks registered nursing among the most in-demand occupations in the country, and the projected growth through the next decade remains strong. But raw demand numbers don't capture the most exciting part of the story: where that demand is coming from. The traditional hospital floor is just one option in an increasingly diverse landscape of nursing careers — many of which pay more, offer better work-life balance, or provide intellectual challenges that rival those of advanced practice providers.
This registered nurse overview is different. I'm going to walk you through the foundational registered nursing information you need, then focus on seven career paths that most RN overviews completely ignore. Whether you're a pre-nursing student trying to understand the profession or a working nurse feeling stuck, this one's for you.
At its core, a registered nurse assesses patients, develops care plans, administers medications and treatments, coordinates with interdisciplinary teams, educates patients and families, and advocates for patient well-being. That's the textbook answer. The real answer is that RNs are the connective tissue of the entire healthcare system — the professionals who translate physician orders into bedside reality, catch the subtle changes that algorithms miss, and hold a patient's hand at 3 a.m. when nothing else will help.
There are three primary educational pathways to becoming an RN:
Regardless of pathway, every RN must pass the NCLEX-RN examination and obtain state licensure. Many states participate in the Nurse Licensure Compact, which allows RNs to practice across state lines — a game-changer if you're considering travel nursing or telehealth roles.
According to sources like the Bureau of Labor Statistics, RN salaries vary significantly by geography, specialty, and experience level. Nurses in metropolitan areas and states with higher costs of living generally command higher compensation. Specialty certifications, advanced degrees, and willingness to work in high-demand settings can all push compensation well above median figures. I won't fabricate a specific number here because it changes frequently, but I encourage you to use the BLS Occupational Outlook Handbook for the most current data.
This is where the standard registered nursing information stops and the real conversation begins. Below are seven RN career paths that deserve far more attention than they get.
If you've ever been curious about the intersection of nursing and interventional cardiology, the cath lab might be your calling. Cath lab nurses work alongside interventional cardiologists during diagnostic and therapeutic cardiac procedures — think angioplasties, stent placements, and electrophysiology studies. The work is procedural, high-stakes, and deeply rewarding.
What makes this path especially interesting is the adjacency to cardiology technology roles. If you've searched for cardiology tech salary data, you've probably noticed that cath lab positions pay competitively — and RNs working in cath labs often earn more than their cardiology tech counterparts because of the expanded scope of practice. Understanding the cardiology tech salary landscape can actually help you negotiate better as a cath lab nurse, because you bring both nursing clinical judgment and procedural expertise that technologists, while highly skilled, don't replicate.
Forensic nurses work at the intersection of healthcare and the justice system. Sexual Assault Nurse Examiners (SANEs) are the most well-known subspecialty, but forensic nurses also work in correctional facilities, medical examiner offices, and psychiatric facilities for the criminally committed. This path requires additional certification and specialized training in evidence collection, chain of custody protocols, and courtroom testimony.
I've spoken with forensic nurses who describe their work as some of the most meaningful in all of healthcare — and some of the most emotionally demanding. If you're drawn to advocacy and have strong emotional resilience, this is worth exploring.
Nurse informatics has been growing quietly for over a decade, but the post-pandemic acceleration of electronic health records and clinical decision-support systems has turned it into one of the hottest RN career paths available. Nurse informaticists bridge the gap between clinical practice and information technology. They design workflows, optimize EHR systems, analyze clinical data, and ensure that technology serves patients rather than burdening clinicians.
What I find compelling about this path is the work environment. Many nurse informaticists work remotely or in hybrid settings, enjoy regular business hours, and earn salaries that are highly competitive with bedside nursing — often exceeding them once you factor in the absence of shift differentials and the reduced physical toll.
Clinical research nurses coordinate and manage clinical trials, ensuring patient safety and protocol compliance while contributing directly to medical advancement. You might work for a pharmaceutical company, an academic medical center, or a contract research organization. The role involves patient screening, informed consent processes, data collection, adverse event monitoring, and collaboration with principal investigators.
This path is ideal for RNs who love science and want to influence care on a population level rather than one patient at a time. The National Institutes of Health and major academic medical centers are consistent employers in this space.
Occupational health nurses work within corporations, manufacturing plants, government agencies, and other non-hospital settings to promote employee health, manage workplace injuries, conduct health screenings, and ensure regulatory compliance with agencies like OSHA. It's a Monday-through-Friday role that still lets you use your clinical skills — a combination that's increasingly rare and incredibly attractive to nurses experiencing burnout from shift work.
Nurse navigators guide patients — most commonly oncology or chronic disease patients — through the complex healthcare system. They coordinate appointments, explain treatment options, connect patients with community resources, and serve as a consistent point of contact throughout the care continuum. This role has expanded significantly as value-based care models have gained traction, and many health systems now employ navigators across multiple service lines.
The nursing skills that translate most directly here are communication, empathy, and systems thinking. If you've ever felt that the most important part of your nursing job is helping patients understand what's happening to them, this could be your niche.
This is the career path that many nurses don't even know exists until they stumble into it. Utilization review nurses work for insurance companies, managed care organizations, or hospital case management departments, reviewing patient records to determine medical necessity, authorize treatments, and ensure appropriate resource utilization. The work is largely desk-based and remote-friendly.
I'll be honest — this path gets mixed reactions from nurses. Some see it as selling out; others see it as a way to influence healthcare policy from the inside while enjoying a sustainable work-life balance. Either way, the demand is robust and the compensation is competitive.
You might be wondering why a registered nurse overview mentions cardiology tech salary at all. Here's why: one of the smartest things a nurse can do when exploring career paths is understand the compensation landscape of adjacent roles. When you know what a cardiology tech earns, you gain leverage in salary negotiations for cardiac nursing positions. You also gain clarity about whether a nursing degree offers meaningfully different earning potential than a technologist credential in the same clinical area.
Generally speaking, RNs working in cardiac specialties tend to earn more than cardiology technologists, reflecting the additional education, licensure requirements, and clinical scope that nursing brings. But the gap varies by region, employer type, and specific role. If you're weighing whether to pursue nursing versus a cardiology technology pathway, I'd recommend comparing not just starting salaries but long-term earning trajectories, advancement opportunities, and scope-of-practice ceilings.
With so many options available, how do you actually choose? Here's the framework I recommend to nurses exploring their next move:
An RN (Registered Nurse) is a licensure designation — it means you've passed the NCLEX-RN and hold an active nursing license. A BSN (Bachelor of Science in Nursing) is an educational degree. You can be an RN with either an ADN or a BSN. However, many employers now prefer or require a BSN, and it's typically needed for advancement into leadership, education, or certain specialty roles.
The timeline depends on your educational pathway. An ADN program typically takes two years, while a BSN program takes four years. Accelerated BSN programs for students who already hold a bachelor's degree in another field can be completed in 12 to 18 months. After completing your program, you'll need to pass the NCLEX-RN before you can practice.
Yes. Many nursing specialties — including cath lab nursing, forensic nursing, occupational health, and utilization review — can be entered with an RN license and on-the-job training, though professional certifications (which typically require passing an exam rather than completing a degree program) can strengthen your candidacy and earning potential.
While specific figures vary by region and employer, RNs working in cardiac specialties generally earn more than cardiology technologists. This reflects the broader educational requirements, licensure standards, and clinical responsibilities that come with the nursing role. However, cardiology tech roles have their own advantages, including shorter training timelines and focused procedural expertise. I'd encourage you to compare current data from the Bureau of Labor Statistics for both roles in your specific geographic area.
Nurse anesthetists (CRNAs) consistently rank among the highest-paid nursing professionals, but that requires a graduate degree. Among specialties accessible to RNs without advanced degrees, cath lab nursing, informatics, travel nursing, and certain procedural specialties tend to offer above-average compensation. Geographic location, shift differentials, and certifications all play significant roles in total compensation.
A truly useful registered nurse overview should do more than recite educational requirements and median salaries. It should open your eyes to possibilities you hadn't considered — and give you the practical framework to pursue them. The seven paths I've outlined here represent just a fraction of what's available to today's RNs, but they illustrate a crucial point: nursing is not a single career. It's a platform for dozens of careers, each with its own rhythm, rewards, and challenges.
Whether you're comparing a cardiology tech salary to an RN role in the cath lab, exploring the quiet appeal of nurse informatics, or considering a complete pivot into forensic nursing, the key is to stay curious and intentional. We built healthcareers.app to help you explore these paths with real job listings, and I'd encourage you to start browsing — not just for open positions, but for inspiration about where your nursing career could go next.
