Free OCN Exam Flashcards

OCN certification validates adult oncology nursing knowledge. It supports professional recognition but does not replace RN licensure, employer competency validation, or state scope-of-practice rules.

Candidates need an active unencumbered RN license, recent RN experience, recent adult oncology nursing practice hours, and recent oncology education before applying.

The exam has 165 multiple-choice questions. Only 145 are scored; 20 are pretest items mixed into the test and should be answered like any other question.

The passing standard is a scaled score of 55 on ONCC's 25-75 scale. It is not a raw percent correct and cannot be directly converted from a practice-test percentage.

ONCC exams use generic drug names. Study medications by generic name, drug class, mechanism, major toxicities, monitoring, and patient teaching.

Study time should follow the OCN blueprint. Symptom management/supportive care and treatment modalities deserve repeated review because they represent the largest share of content.

Prioritize risks that are important and changeable, such as tobacco use, UV exposure, alcohol use, vaccination gaps, physical inactivity, and occupational exposures. Teach without blame.

Screening applies to asymptomatic people. New symptoms, abnormal findings, or positive screening results require diagnostic follow-up rather than routine screening advice.

Refer for genetic risk assessment when history suggests inherited risk, such as young-onset cancer, multiple relatives in a pattern, rare cancers, or multiple primary cancers.

Navigation reduces delays by coordinating appointments, clarifying next steps, addressing barriers, and closing referral loops across diagnosis, treatment, survivorship, and end-of-life care.

A survivorship plan summarizes diagnosis and treatment, surveillance needs, late effects, health maintenance, recurrence symptoms, psychosocial needs, and who owns follow-up care.

Palliative care can begin at diagnosis and continue with disease-directed therapy. It focuses on symptom relief, communication, goals, caregiver support, and quality of life.

Malignant tumors can invade surrounding tissue and metastasize. Benign tumors may still cause problems by location or pressure, but they do not metastasize.

TNM describes tumor extent, regional lymph node involvement, and distant metastasis. Nurses use staging to understand prognosis, treatment intent, teaching needs, and surveillance plans.

Performance status estimates functional ability and treatment tolerance. Declining function can affect eligibility for therapy, need for rehabilitation, goals-of-care discussions, and safety planning.

Tumor markers can help with monitoring, prognosis, or treatment response in selected cancers, but they usually cannot diagnose cancer by themselves and must be interpreted in context.

Early trials emphasize dose, safety, and toxicity. Later trials compare effectiveness, monitor outcomes, and may involve larger patient groups. Informed consent is always essential.

Evidence-based practice combines current research, clinical expertise, patient preferences, and local policy. It is stronger than habit, tradition, or anecdote alone.

Chemotherapy is often given in cycles to target cancer cells while allowing normal tissues, especially marrow and mucosa, time to recover between treatments.

Suspected vesicant extravasation requires stopping the infusion, leaving access in place, following the drug-specific protocol, notifying the provider, and documenting assessment and interventions.

Anthracyclines such as doxorubicin can impair cardiac function. Monitor for dyspnea, edema, fatigue, reduced ejection fraction, and other signs of heart failure.

Cisplatin can cause nephrotoxicity, ototoxicity, neuropathy, and significant nausea. Hydration status, renal function, urine output, hearing changes, and antiemetic adherence are key.

Teach gentle cleansing, protection from friction and sun, avoidance of unapproved products on the treatment field, and prompt reporting of moist desquamation or infection signs.

Brachytherapy places radiation close to or inside the tumor. Nursing priorities include time, distance, shielding, source precautions, visitor limits, and clear instructions if a source dislodges.

Checkpoint inhibitors can trigger immune-related adverse events in organs such as colon, lung, liver, skin, endocrine glands, and kidneys. New inflammatory symptoms need early reporting.

Targeted therapies act on specific molecular pathways or receptors. Patient teaching should connect the target to expected benefit, unique toxicities, adherence, and required monitoring.

Oral therapy requires the same safety attention as infusion therapy: correct schedule, missed-dose instructions, interaction review, safe handling, storage, adherence checks, and toxicity reporting.

Allogeneic transplant uses donor cells and can cause graft-versus-host disease. Watch for rash, diarrhea, liver changes, mucosal symptoms, infection, and need for immunosuppression.

Use proper personal protective equipment, closed-system transfer devices when required, spill procedures, disposal controls, and pregnancy or reproductive-risk protections according to policy.

Before using a central line, assess patency, blood return per policy, dressing integrity, infection signs, patient symptoms, and any concern for malposition or thrombosis.

Pain, swelling, absent blood return, leakage, fever, erythema, arm or neck swelling, or respiratory symptoms can signal complications and require escalation before treatment continues.

Breakthrough pain is a flare despite baseline analgesia. Assess pattern, triggers, sedation, bowel regimen, adherence, and whether the long-acting regimen needs adjustment.

Constipation from opioids is expected and does not usually improve with tolerance. Prevention often requires stimulant laxatives, bowel assessment, hydration, mobility, and escalation if obstructive symptoms appear.

Prevention works better than rescue. Match antiemetics to emetic risk, timing, prior response, breakthrough symptoms, hydration status, constipation, anxiety, and home medication access.

Mucositis care includes frequent gentle oral care, pain control, infection assessment, nutrition support, avoidance of irritants, and escalation when intake or airway safety is threatened.

Assess reversible contributors such as anemia, sleep disruption, depression, pain, medications, infection, and deconditioning. Activity pacing and tailored exercise often help more than prolonged bed rest.

Peripheral neuropathy may cause numbness, tingling, pain, weakness, gait instability, or difficulty with fine motor tasks. Safety teaching and prompt dose-toxicity communication are important.

Hand-foot syndrome causes painful redness, swelling, peeling, or tenderness on palms and soles. Reduce friction and heat, moisturize, protect skin, and report functional impairment.

Lymphedema care focuses on early recognition, skin protection, infection prevention, compression or therapy referral, exercise guidance, and avoiding trauma to the affected limb when possible.

Assess reversible causes first, then support positioning, airflow, anxiety reduction, oxygen when hypoxemic, and prescribed opioids for refractory breathlessness when appropriate.

Fever during neutropenia is an emergency. Follow the urgent pathway for assessment, cultures as ordered, rapid antibiotics, provider notification, and sepsis monitoring.

Tumor lysis syndrome results from rapid cancer cell breakdown. Watch for hyperkalemia, hyperphosphatemia, hypocalcemia, hyperuricemia, renal injury, dysrhythmias, seizures, and need for urgent treatment.

New back pain with weakness, sensory changes, gait problems, or bladder and bowel dysfunction suggests cord compression. Treat as urgent to protect neurologic function.

Facial or upper-extremity swelling, dyspnea, cough, distended neck veins, and head fullness can indicate impaired venous return from the upper body and require prompt evaluation.

Concerning findings include weakness, confusion, constipation, polyuria, dehydration, and dysrhythmias. Management commonly emphasizes hydration, cardiac monitoring, and ordered calcium-lowering therapy.

Disseminated intravascular coagulation causes abnormal clotting and bleeding from clotting factor consumption. Monitor bleeding, thrombosis, labs, hemodynamics, and treatment of the underlying trigger.

After cellular or immune therapy, fever, hypotension, hypoxia, and organ dysfunction can signal cytokine release syndrome. Early grading and escalation are critical.

When a patient expresses fear, guilt, anger, or despair, first assess meaning and emotion. Avoid false reassurance, judgment, or immediately changing the subject.

Ask about the patient's values, decision-making preferences, language needs, spiritual practices, and family roles. Use qualified interpreters rather than family members for medical interpretation.

Cancer costs can cause missed appointments, unfilled prescriptions, unsafe dose changes, and distress. Screen for barriers and connect patients with social work, pharmacy, and assistance resources.
