CNA in a Hospital: Duties, Pay, Patient Ratios & How to Get Hired
Over 40% of all Certified Nursing Assistants work in hospitals — the largest single employer of CNAs in the United States. Hospital CNAs earn an average of $19–$24/hour, roughly 15–20% more than nursing home CNAs, and gain exposure to every type of patient care from emergency triage to post-surgical recovery. This guide covers exactly what a hospital CNA does, legal patient ratios, medication rules, and how to get hired.
Quick Reference: Review the sections below for a comprehensive guide to CNA — covering exam structure, preparation strategies, and what to expect on test day.
What Does a CNA Do in a Hospital?
A hospital CNA (Certified Nursing Assistant) provides hands-on patient care under the supervision of Registered Nurses (RNs) and Licensed Practical Nurses (LPNs). Unlike nursing home CNAs who follow a predictable daily schedule with long-term residents, hospital CNAs work in fast-paced, high-acuity environments where patient needs change rapidly.
The core responsibilities of a CNA in a hospital include:
- Vital signs monitoring — blood pressure, temperature, pulse, oxygen saturation every shift (or more frequently for ICU patients)
- Activities of Daily Living (ADLs) — bathing, grooming, dressing, oral hygiene, and toileting assistance
- Ambulation and repositioning — helping patients walk, turn every 2 hours to prevent pressure sores, and transfer safely
- Intake and output (I&O) tracking — documenting fluids consumed and urine/drainage output
- Specimen collection — urine, stool samples, and blood draws (if trained as a phlebotomist)
- Patient observation — reporting changes in skin condition, mental status, pain level, or behavior to the RN immediately
- Equipment setup — preparing beds, monitoring equipment, and supplying rooms
- Patient communication — answering call lights, providing emotional support, and relaying patient concerns to the care team
Hospital CNAs also document all care activities in the Electronic Health Record (EHR) system — typically Epic or Cerner — making accurate charting a critical job skill.
Hospital CNA Duties by Department
CNA responsibilities vary significantly by hospital unit. Here's what to expect in each setting:
Medical-Surgical (Med-Surg) is where most hospital CNAs start. Patients are post-surgical or receiving medical treatment for conditions like pneumonia, diabetes complications, or cardiac issues.
- CNA-to-patient ratio: typically 1:8–12
- High ADL load — most patients need full assistance with bathing, mobility, and meals
- Post-surgical wound monitoring (observation only — not wound care)
- Frequent vital signs, ambulation support after surgery
- Fast bed turnover — a patient may discharge and be replaced within hours
Best for: CNAs who want volume, variety, and a fast learning curve.
The Intensive Care Unit (ICU) has the lowest patient ratios and the highest acuity. Most ICU CNAs work alongside RNs on a 1:2 nurse-to-patient assignment.
- CNA-to-patient ratio: typically 1:4–6
- Patients on ventilators, continuous IV drips, or post-cardiac surgery
- Mouth care for intubated patients (critical for preventing VAP)
- Proning patients (prone positioning) — requires training and a team lift
- Strict I&O tracking, hourly in some units
- Emotional support for families in crisis
Best for: CNAs who want to learn advanced clinical skills and work closely with the care team.
The Emergency Department (ED) is the most unpredictable unit. CNAs often function as patient care technicians (PCTs) with expanded duties.
- No fixed patient ratio — census fluctuates hourly
- EKG placement and interpretation monitoring (after training)
- Phlebotomy and IV start assistance (where scope allows)
- Patient triage support — room setup, vitals on arrival
- Splint and wound prep assistance
- Mental health holds — safety monitoring and de-escalation
Best for: CNAs who thrive in high-energy, unpredictable environments and want PCT cross-training.
The Pediatric Unit requires a different skill set — working with children and their families demands patience, play-based communication, and family-centered care.
- CNA-to-patient ratio: typically 1:6–10
- Age-appropriate vital sign ranges — must know norms for infants, toddlers, and teens
- Distraction techniques during procedures — toys, tablets, calm presence
- Parent education and family communication support
- Growth measurement — height, weight, head circumference for infants
- Safety: crib rails, ID band checks, fall prevention for mobile toddlers
Best for: CNAs who love working with children and families, and have patience for higher emotional demands.
The Oncology Unit cares for cancer patients undergoing chemotherapy, radiation, or surgical recovery. It requires emotional resilience and infection-control rigor.
- CNA-to-patient ratio: typically 1:8–10
- Strict neutropenic precautions — PPE and hand hygiene are non-negotiable
- Managing nausea, fatigue, and pain side effects from chemotherapy
- Central line care awareness (RN responsibility, but CNA monitors site)
- Palliative and end-of-life comfort care — repositioning, mouth care, family presence
- Emotional support — many oncology patients have long, recurring admissions
Best for: CNAs with strong emotional intelligence and interest in long-term patient relationships.
Hospital CNA Daily Responsibilities
Receive shift handoff report from outgoing CNA or nurse Complete safety rounds — check all assigned patients within first 30 minutes Obtain and document vital signs (BP, temp, pulse, SpO2, respirations) Assist with morning ADLs — bathing, oral care, grooming, dressing Reposition immobile patients every 2 hours to prevent pressure injuries Assist patients to ambulate or use bedside commode as ordered Record all fluid intake and urine/drainage output accurately Respond to call lights promptly — within 5 minutes per most hospital standards Change bed linens and maintain a clean, safe patient environment Transport patients to imaging, therapy, or procedures as requested Report any changes in patient condition to the charge nurse immediately Chart all completed care activities in the EHR before end of shift Give a complete handoff report to the oncoming CNA CNA-to-Patient Ratios in Hospitals
The CNA-to-patient ratio determines how many patients each nursing assistant is responsible for during a shift. This is one of the most important factors affecting both patient safety and CNA job satisfaction — and it varies dramatically by unit and state.
Typical hospital CNA ratios by unit

Cardiac monitoring; patients more independent |
State staffing laws
As of 2026, California is the only state with legally mandated CNA-to-patient ratios in hospitals (1:2 in ICU, 1:6 in Med-Surg). Other states rely on hospital policies, union contracts, or nurse-to-patient ratio laws that indirectly affect CNA staffing. Check your state's Department of Health for current requirements.
For context: how many patients can a CNA have legally depends on your state and facility type. In California's nursing homes, the minimum is 3.5 hours of nursing aide care per resident per day — which translates to roughly 1:10 during a shift. Hospital minimums are less regulated outside California.
Can a CNA Administer Medication in a Hospital?
Standard CNAs cannot administer medication in a hospital. This is a legally protected nursing function reserved for RNs, LPNs, and physicians. A CNA who administers medication — even something as routine as an aspirin — is practicing outside their scope and risks immediate termination and license revocation.
However, there are two important exceptions:
1. Medication Aide / Medication Technician (CNA Med Tech)
Some states allow CNAs to earn an additional certification as a Medication Aide (CMA) or CNA Med Tech. With this certification, a CNA can administer oral, topical, and eye/ear drop medications only in specific settings (typically nursing homes and assisted living — NOT acute care hospitals) under RN supervision.
States that allow CNA medication aide roles include: Florida, Texas, Virginia, Colorado, Missouri, and others. Each state has different requirements — typically a 40–80 hour course plus a state exam.
2. Patient Care Technicians (PCTs) in the ED
Emergency Departments sometimes employ Patient Care Technicians (PCTs) — CNAs with expanded training who can start IVs, draw blood, and perform EKGs. PCTs do not administer IV medications, but they work closely with RNs who do.
If a patient asks you to give them their medication or hand them pills from their own supply — refuse politely and alert the nurse immediately. This is the correct and legally required response in every hospital setting.
Hospital CNA Salary: What to Expect
Hospital CNAs consistently out-earn their nursing home counterparts due to higher acuity demands and the competitive labor market for healthcare workers.
| Setting |
Avg. Hourly (2026) |
Avg. Annual |
| Hospital (ICU/ED) |
$21–$27 |
$44,000–$56,000 |
| Hospital (Med-Surg) |
$19–$24 |
$39,000–$50,000 |
| Nursing Home / SNF |
$16–$20 |
$33,000–$41,000 |
| Home Health Agency |
$15–$19 |
$31,000–$39,000 |
Night shifts and weekend shifts add $1.50–$3.00/hour in shift differentials at most hospitals. Union hospitals (common in California, New York, Massachusetts) pay even more — union CNAs average $24–$31/hour in high-cost-of-living states.
Career advancement from hospital CNA
Hospital experience is the best foundation for healthcare advancement. Common paths:
- LPN — 12–18 month program, average $50,000/year
- PCT / ED Tech — add phlebotomy, EKG, IV start certifications
- RN (ADN or BSN) — many hospitals offer tuition reimbursement for CNA-to-RN bridge programs
- Surgical Tech — 18-month certification, $55,000+ average
How to Get Hired as a Hospital CNA
Hospital CNAs are in demand, but competition is real — especially for ICU and ED positions. Use these strategies to stand out:
1. Get your state CNA license first
All hospitals require an active CNA certification before hiring. You must pass your state's written and skills exams through an accredited program. Most CNA training programs near you can be completed in 4–12 weeks — full-time accelerated or part-time evening/weekend options are common.
2. Target hospitals with CNA internship programs
Many large hospital systems (HCA Healthcare, CommonSpirit, Kaiser Permanente, Ascension) run new graduate CNA programs that provide 4–6 weeks of unit-specific orientation with a mentor CNA. These programs are ideal for new CNAs with no hospital experience.
3. Start in Med-Surg, advance to specialty units
ICU and ED positions rarely go to brand-new CNAs. Spend 6–12 months on a Med-Surg or Telemetry unit building your speed, charting skills, and nurse relationships — then internally transfer to your target unit. Internal transfers are far easier than external applications for specialty positions.
4. List your CNA clinicals prominently
Your CNA clinicals (the hands-on portion of your CNA training) count as hospital experience on your resume — especially if you completed them in a hospital rather than a nursing home. List the facility name, unit, and total hours completed.
5. Highlight EHR experience
Any experience with Epic, Cerner, or Meditech in your clinical training is highly valued. Mention it specifically in your application — many hospital recruiters filter by this skill.
CNA Pros and Cons
Pros
- CNA salary data provides benchmarks that help professionals negotiate compensation and evaluate job offers objectively
- Understanding salary ranges by experience level helps professionals plan career progression and timing of role changes
- Geographic salary variation data helps candidates evaluate relocation decisions with accurate financial context
- Specialty or certification premiums within the field provide clear ROI data for professional development investments
- Published salary data creates transparency that reduces information asymmetry in compensation negotiations
Cons
- Published salary averages may not reflect local market conditions — cost of living differences make national averages misleading in high-cost cities
- Salary surveys may be based on self-reported data from non-representative samples, potentially skewing results
- Entry-level salary data is often less accurate than mid-career data, as entry-level roles vary widely in scope and title
- Benefits, bonuses, and total compensation can vary as much as base salary, making base salary comparisons incomplete
- Salary data ages quickly in high-demand fields — reports more than 1–2 years old may significantly understate current market rates
Hospital CNA Questions and Answers
Can a CNA work in a hospital?
Yes. CNAs can work in almost every hospital department — Medical-Surgical, ICU, Emergency, Pediatrics, Oncology, Labor & Delivery, and more. Hospital positions typically require an active state CNA license and a background check. Some specialty units (ICU, ED) prefer candidates with at least 6–12 months of prior CNA experience.
What is the difference between a hospital CNA and a nursing home CNA?
Hospital CNAs work with acutely ill patients for short stays (average 4–5 days), have faster-paced shifts with more frequent patient turnover, and generally earn higher wages. Nursing home CNAs care for the same residents long-term with a more predictable daily schedule. Hospital CNAs also use electronic health record systems more extensively and work more closely with physicians and advanced practice nurses.
Do hospital CNAs work 12-hour shifts?
Most hospital CNAs work 12-hour shifts — either 7 AM to 7 PM (days) or 7 PM to 7 AM (nights) — three days per week. Some hospitals offer 8-hour shifts for part-time or per diem CNAs. Night and weekend shifts come with shift differential pay of $1.50–$3.00/hour extra.
What is a CNA patient care technician?
A CNA Patient Care Technician (PCT) is a CNA who has received additional training in expanded skills such as phlebotomy (blood draws), EKG placement, and point-of-care testing. PCTs are common in Emergency Departments and are paid slightly more than standard CNAs — typically $1–$3/hour more. Most hospitals provide PCT training in-house after hiring a CNA.
How do I become a hospital CNA with no experience?
Complete a state-approved CNA training program (4–12 weeks), pass your state's written and skills exams, and apply to hospitals with new graduate CNA programs. Start with Med-Surg or Telemetry positions, which are the most open to new CNAs. Your CNA clinicals count as experience — list the hospital or facility name and total hours on your resume.
What is the CNA-to-patient ratio in a hospital?
It varies by unit and state. Typical ratios: ICU (1:4–6), Emergency Dept (1:8+, census-driven), Pediatrics (1:6–10), Med-Surg (1:8–12), Telemetry (1:10–14). California is the only state with legally mandated hospital staffing ratios. Other states rely on hospital policy or union contracts. Higher patient ratios mean more demanding shifts but are standard in many facilities.
