The current Oregon CNA knowledge test has 80 questions in 90 minutes and requires 73%. On the skills component, candidates need at least 80% on every assigned task without missing a bolded key step. Since July 1, 2025, Oregon has one CNA level and the minimum approved training program is 105 hours: 37 classroom, 28 supervised lab, and 40 supervised clinical. OSBN requires the application, both exam components, and the background-check process before certification is issued.

Sample Oregon CNA Practice Questions

Try these sample questions to test your Oregon CNA exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 498+ question experience with AI tutoring.

1When assisting an Oregon nursing facility resident with a complete bed bath, which area of the body should the CNA wash LAST?
A.The back and buttocks
B.The perineal area
C.The face and neck
D.The feet and toenails
Explanation: The perineal area should always be washed last during a complete bed bath, moving from the cleanest area (face) to the dirtiest (perineal). This sequence prevents cross-contamination and reduces the risk of urinary tract infections. This principle applies in all Oregon long-term care facilities regulated by the Oregon Department of Human Services (ODHS).
2A resident at an Oregon long-term care facility has left-sided weakness following a stroke. When helping the resident get dressed, the CNA should:
A.Dress the right (stronger) arm first to prevent muscle fatigue
B.Dress the left (weaker) arm first to minimize discomfort and strain
C.Have the resident choose which arm to dress first
D.Call the nurse before assisting with dressing to get permission
Explanation: The correct technique is to dress the weak or affected side first and undress the strong side first. When dressing the left (weaker) arm first, the garment is positioned over the arm with limited mobility before threading the stronger arm through. This reduces pain and the risk of injury. The mnemonic is: "Dress the worst first, undress the best first."
3While providing oral care to an unconscious resident at an Oregon nursing facility, the CNA should position the resident:
A.Flat on the back (supine) to prevent neck strain
B.In a sitting position at 90 degrees
C.On the side (lateral position) with the head turned to allow drainage
D.Prone (face-down) to keep the airway clear
Explanation: An unconscious resident must be positioned on their side (lateral/Sims position) with the head turned during oral care to prevent aspiration of fluids into the lungs. The supine position is dangerous for unconscious patients because secretions and fluids can pool in the throat and be aspirated. This is a critical safety measure taught in all Oregon OSBN-approved CNA training programs.
4A resident in an Oregon nursing facility requests that the CNA leave the room during a bed bath. The CNA should:
A.Refuse and explain that the bath must be completed for the resident's health
B.Leave the room but check back every 5 minutes to ensure safety
C.Respect the resident's right to privacy and modify the approach to meet the resident's wishes
D.Notify the nurse immediately that the resident is being non-compliant
Explanation: Residents have the right to privacy and to refuse or modify care per OBRA (Omnibus Budget Reconciliation Act), which is enforced in all Oregon nursing facilities. The CNA should work with the resident to find an acceptable approach, such as having the resident wash certain areas independently. Resident rights are protected under Oregon's nursing home regulations and federal law.
5When performing nail care for a diabetic resident at an Oregon long-term care facility, the CNA should:
A.Clip toenails straight across and report any abnormalities to the nurse
B.Clip and file the toenails to keep them short and smooth
C.Refer all nail care for diabetic residents to the nurse or podiatrist
D.Soak the feet for 30 minutes before clipping to soften the nails
Explanation: CNAs should NOT clip the toenails of diabetic residents. Diabetics have reduced blood circulation and nerve sensation in the feet, making even minor cuts from nail clipping potentially serious. Toenail care for diabetic residents must be performed by a nurse or licensed podiatrist. The CNA can soak and clean the feet but must refer nail trimming to a licensed professional. This is a scope-of-practice limitation in Oregon.
6A resident at an Oregon nursing facility has dentures. When storing the resident's dentures overnight, the CNA should:
A.Store them dry in a labeled container to prevent bacterial growth
B.Rinse them with hot water and store in the resident's bedside drawer
C.Place them in a labeled container with cool water or a denture cleanser solution
D.Wrap them in a tissue and place them on the bedside table
Explanation: Dentures should be stored in a labeled container filled with cool water or a denture cleanser solution when not being worn. Hot water can warp dentures, causing them to not fit properly. Storing them dry can cause the plastic to crack or distort. Tissues and napkins are inappropriate because dentures can accidentally be thrown away. Each resident's denture container must be labeled with their name.
7While assisting a female resident with perineal care following urinary catheter use in an Oregon nursing facility, the CNA should clean:
A.In a circular motion around the catheter tubing
B.From the catheter insertion site outward, using a clean stroke each time
C.Back to front using gentle pressure
D.Starting from the outer areas and moving toward the catheter insertion site
Explanation: Catheter perineal care should be performed starting from the urethral meatus (catheter insertion site) and moving outward away from the body, using a clean stroke each time to avoid introducing bacteria toward the urethra. This technique, along with cleaning the catheter tubing for several inches, reduces the risk of catheter-associated urinary tract infections (CAUTIs), which are a major concern in Oregon long-term care facilities.
8When helping a resident use a bedpan in an Oregon nursing facility, the CNA should:
A.Place the bedpan under the resident and leave for 30 minutes
B.Warm the metal bedpan before use and provide privacy with the call light within reach
C.Position the resident flat on the back with a pillow under the head for comfort
D.Remove the bedpan immediately after use without covering
Explanation: When using a bedpan, warm a cold metal bedpan by running warm water over it (cold metal can cause discomfort or skin injury). Always ensure privacy for the resident, and leave the call light within reach so they can signal when finished. The resident should be raised to as close to a normal sitting position as possible (bed at 30-45 degrees) and should not be left for extended periods. Cover the bedpan when removing it to respect dignity.
9An Oregon CNA notices a resident's incontinence brief is soiled. The CNA should change it:
A.Only at scheduled times (morning, noon, and evening) to maintain routine
B.Immediately after discovering it is soiled to prevent skin breakdown
C.After informing the charge nurse and getting approval
D.Only if the resident complains of discomfort
Explanation: Soiled briefs must be changed immediately upon discovery to prevent skin breakdown, pressure injuries, and infections such as urinary tract infections. Prolonged contact with urine and feces causes skin maceration and irritation that can quickly progress to serious pressure injuries. Oregon nursing homes are cited and penalized by ODHS inspectors for failure to maintain skin integrity related to incontinence care.
10A resident with contractures in both hands is receiving a bed bath at an Oregon nursing facility. When cleaning between the fingers, the CNA should:
A.Force the fingers open to clean thoroughly between them
B.Gently open the hand and clean between the fingers without forcing the joints
C.Skip this area to avoid causing pain
D.Use a cotton swab to insert between the closed fingers
Explanation: Residents with contractures have permanently flexed joints that cannot be fully straightened. The CNA should gently work within the resident's range of motion, carefully and slowly opening the hand as much as is comfortable, then cleaning between the fingers without forcing the joints. Forcing contracted joints can cause severe pain, muscle tears, or fractures. Skipping hygiene in flexed areas leads to skin breakdown and infection.

About the Oregon CNA Exam

Frequently Asked Questions

Who administers the Oregon CNA exam?

Oregon CNA exams are administered by Headmaster (D&S Diversified Technologies) under the Oregon State Board of Nursing (OSBN). After OSBN releases a candidate to test, knowledge and skills appointments are scheduled in Oregon TMU at or.tmutest.com.

What is the passing score for the Oregon CNA exam?

The current Headmaster handbook requires 73% or better on the 80-question knowledge test. For the skills component, a candidate must score at least 80% on every assigned task and may not miss any bolded key step.

How much does the Oregon CNA exam cost?

The current OSBN fee schedule lists $106 for certification by examination, inclusive of the exam components. A skills retake is $45 and a knowledge retake is $25; separate third-party fingerprinting costs may also apply.

How many hours of training does Oregon require for CNAs?

Since July 1, 2025, an OSBN-approved nursing assistant program must provide at least 105 hours: 37 classroom, 28 supervised laboratory, and 40 supervised clinical hours. The former 155-hour figure is obsolete.

What are Oregon's CNA renewal requirements?

Oregon CNA certification renews periodically under OSBN rules. As of January 1, 2026, CNA renewal competency is shown with two hours of cultural-competency education in the preceding 48 months; the former 400-hour practice requirement no longer applies.

What are the abuse reporting requirements for Oregon CNAs?

A CNA should immediately protect the client, follow required Oregon abuse-reporting channels, and follow employer policy. Merely telling a supervisor should not be presented as a universal substitute for any direct report required by law.

Can I perform CNA duties before OSBN issues the certificate?

Do not assume a blanket grace period. Oregon rules require active CNA certification and registry listing before a person performs CNA authorized duties. A student nursing assistant in a Board-approved training program may perform duties with appropriate supervision, but completing training or the exam alone does not issue certification.

What is the difference between CNA 1 and CNA 2 in Oregon?

As of 2025, Oregon eliminated the distinction between CNA 1 and CNA 2. There is now a single CNA certification level. Previously, CNA 2 required additional training for more complex tasks.
