  • Supervise and delegate appropriate tasks to licensed practical nurses (LPNs) and unlicensed assistive personnel (UAP) within state scope of practice

Overview

A registered nurse is the constant in the patient's experience of healthcare. While physicians visit for minutes during rounds, nurses are present for the full shift — assessing for changes, managing medications, catching the early signs of deterioration, and translating clinical events into terms patients and families can understand and act on.

On a medical-surgical floor, a typical nurse manages 5–7 patients through an 8 or 12-hour shift. The shift starts with a handoff report from the outgoing nurse, then a patient round to assess baseline status, review orders, check IV sites, and introduce oneself to patients who are newly admitted. From there the shift is a managed series of tasks and interruptions: medications due, a patient whose blood pressure has dropped, a family member with questions, a discharge to coordinate, a new admission coming from the ED, an IV that infiltrated and needs to be restarted.

Specialty nursing units change the patient population and the technical demands but not the fundamental structure of the role. In the ICU, nurses manage 1–2 critically ill patients on ventilators, vasopressors, and continuous monitoring, with intensive charting requirements and close collaboration with the medical team. In labor and delivery, nurses manage two patients simultaneously — mother and fetus — through a process that can shift from low-risk to emergency in minutes. In the OR, nurses function in scrub or circulating roles that require sterile technique, equipment proficiency, and the ability to support a surgical procedure while tracking supplies, documenting, and anticipating the surgeon's next step.

Nursing is one of the few occupations that remains fundamentally human regardless of technological advance. Assessment requires hands, eyes, and the clinical intuition that develops only through experience. Therapeutic presence — sitting with a frightened patient, explaining a diagnosis to a crying family — cannot be delegated to software.

Qualifications

Education:

  • Associate Degree in Nursing (ADN/ASN) — 2 years, qualifies for NCLEX; common entry path but BSN increasingly expected
  • Bachelor of Science in Nursing (BSN) — 4 years or 2-year bridge for ASN holders; preferred/required by many employers
  • Accelerated BSN (ABSN) — 12–18 months for career changers with non-nursing bachelor's degrees
  • MSN or DNP for advanced practice or leadership roles

Licensure:

  • NCLEX-RN passage — required in all states and U.S. territories
  • State RN license (or Nurse Licensure Compact multistate license if in compact state)
  • BLS — required at all healthcare employers
  • ACLS — required for critical care, ED, and procedural areas

Specialty certifications (examples):

  • CCRN (critical care), CEN (emergency nursing), RNC-NIC (neonatal intensive care), CNOR (perioperative), OCN (oncology), CDE (diabetes education), CMSRN (med-surg)
  • ANCC specialty certification available for most nursing specialties — typically requires 2,000+ hours of specialty practice plus examination

Skills expected at most acute care facilities:

  • IV insertion, PICC care, central line maintenance
  • Blood administration and transfusion monitoring
  • Wound assessment, dressing changes, negative pressure wound therapy
  • Foley catheter insertion and care
  • NG tube insertion and tube feeding management
  • EHR documentation: Epic, Cerner, Meditech

Career outlook

Nursing is consistently ranked among the most in-demand professions in the United States, and that designation will remain accurate for the foreseeable future. The Bureau of Labor Statistics projects a 6% growth rate for RNs through 2032 — but in the context of a specialty experiencing active shortages today, that number understates the near-term demand.

The drivers are structural. Baby Boomers are aging into the highest healthcare utilization years of their lives. The existing nursing workforce is also aging — a significant share of experienced RNs are approaching retirement age. Nursing school enrollment has increased, but clinical training slot constraints limit how quickly new graduates can enter the workforce. The pandemic caused tens of thousands of experienced nurses to exit the profession earlier than planned.

The geographic distribution of the shortage is uneven. Rural hospitals, inner-city safety-net facilities, and skilled nursing facilities face the most severe staffing challenges. Urban academic medical centers with higher wages and training reputations are better positioned to recruit but not immune to vacancies. Long-term care nursing — SNFs, assisted living, memory care — faces a persistent crisis that higher wages alone have not resolved.

Career advancement paths for RNs are among the most diverse in healthcare. Staff RNs can advance to charge nurse, unit manager, or director of nursing through the administrative track. Clinical advancement tracks (clinical nurse II, III, IV) recognize expertise without requiring administrative responsibility. APRN programs convert RN experience into prescribing authority — with NP programs producing practitioners who earn $115K–$165K in primary care and considerably more in acute and specialty care.

For someone entering nursing in 2026, the combination of persistent demand, geographic flexibility (RN licenses transfer between compact states), and multiple career tracks makes it one of the most durable healthcare investments available.

Sample cover letter

Dear Nursing Recruiter,

I am applying for the Registered Nurse position on the Medical-Surgical/Telemetry unit at [Hospital]. I graduated from [University]'s BSN program in May and passed the NCLEX-RN in June. I hold an active [State] RN license and current BLS and ACLS certifications.

During my clinical placements I completed rotations in med-surg, telemetry, the ED, and a four-week senior practicum on a 36-bed cardiac step-down unit where I worked under the supervision of a preceptor managing a full patient assignment with me. By the third week I was leading patient assessments and medication administration for five patients and reporting directly to the charge nurse when I had concerns.

The clinical experience that prepared me best for a telemetry role was in my senior practicum, where I had two patients with new atrial fibrillation being rate-controlled and two post-MI patients on heparin infusions. I became much more comfortable reading telemetry strips during that rotation — not just identifying rhythms but understanding what the clinical context of each rhythm change was and when it required escalation.

I'm drawn to [Hospital] because of the clinical ladder and the tuition support for CCRN preparation. My longer-term goal is to move into critical care, and I believe a strong med-surg/tele foundation — with structured performance feedback and access to certification support — is the right path.

I am available for 12-hour day or night shifts and flexible on start date.

Thank you.

[Your Name], BSN, RN

Frequently asked questions

What is the difference between an ASN and a BSN, and does it matter?
An Associate of Science in Nursing (ASN or ADN) is a two-year program that qualifies graduates for the NCLEX-RN. A Bachelor of Science in Nursing (BSN) is a four-year degree. Both lead to the same RN license, but many hospitals — particularly Magnet-designated facilities — require new hires to hold or complete a BSN within 2–3 years. BSN nurses statistically earn more and advance to leadership roles more readily. Entry-level hiring is possible with an ASN, but BSN completion is increasingly expected.
What does the NCLEX-RN exam involve?
The NCLEX-RN is a computer-adaptive exam that tests the nursing knowledge and clinical judgment needed for entry-level safe practice. It uses Next Generation NCLEX (NGN) question formats as of 2023 — including case studies and clinical judgment measurement items rather than simple multiple choice. Candidates answer between 75 and 145 questions, with the exam stopping when the computer determines with 95% confidence whether the candidate passes or fails.
What nursing specialties are in the highest demand?
ICU/critical care, emergency nursing, OR/perioperative nursing, and labor and delivery are consistently among the hardest-to-fill specialties. Psychiatric nursing has a severe shortage. Home health and skilled nursing facility nursing have persistent vacancies driven by working conditions and pay disparities relative to hospital roles. Travel nurses are in highest demand for these same specialties.
What is the difference between an RN and an Advanced Practice Registered Nurse (APRN)?
APRNs — Nurse Practitioners, Certified Registered Nurse Anesthetists, Certified Nurse-Midwives, and Clinical Nurse Specialists — hold master's or doctoral degrees in nursing and practice at an advanced scope that typically includes diagnosis, prescribing, and independent patient management. RNs do not diagnose or prescribe. APRNs earn $105K–$200K+ depending on specialty, significantly above staff RN wages.
How is the RN workforce shortage affecting nurse workloads?
Nursing shortages have driven higher patient-to-nurse ratios at many facilities, contributing to burnout, nurse turnover, and patient safety concerns. Research consistently links nurse staffing to patient outcomes — higher ratios are associated with increased hospital-acquired complications and mortality. Several states have implemented or are debating mandated staffing ratios, following California's pioneering 1999 law. The shortage is projected to deepen through 2030 before new graduates close the gap.
