ONCC Advanced Oncology Certified Nurse Practitioner Examination Practice Test

Advanced oncology nurse practitioners integrate cancer-treatment knowledge with assessment, symptom management, and shared clinical decision-making. Practice-bank questions sample scenarios involving immunotherapy-related diarrhea, vaccination during systemic treatment, cancer pain, nutritional concerns, possible bowel obstruction, transfusion reactions, swallowing difficulties, hereditary cancer risk, informed consent, and anticoagulant use before procedures.

About the ONCC Advanced Oncology Certified Nurse Practitioner Examination Exam

The work represented in these scenarios requires distinguishing urgent complications from symptoms that can be assessed and managed through planned follow-up. Examples include recognizing possible immune-mediated colitis, stopping a transfusion when an acute reaction is suspected, and prioritizing evaluation of vomiting and abdominal distention with imaging evidence of obstruction. Other questions call for safe medication counseling, such as explaining as-needed immediate-release morphine, or patient-specific guidance about vaccination and anticoagulation. Clinical communication is also central: clinicians elicit treatment concerns, support informed decisions, assess nutrition and swallowing, and identify family-history features that warrant hereditary cancer risk assessment. Together, these situations exercise differential assessment, risk recognition, supportive-care planning, patient education, and timely escalation of care across cancer treatment.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A patient receiving immune checkpoint inhibitor therapy reports new frequent watery stools and abdominal cramping. What is the most appropriate next step?

  1. AAssess severity and promptly notify the oncology team about possible immune-mediated colitis
  2. BRecommend an over-the-counter antidiarrheal and defer reporting unless symptoms last a month
  3. CAssume the symptoms are unrelated to treatment because immunotherapy does not affect the bowel
  4. DAdvise the patient to discontinue all medications, including essential maintenance medicines
Show answerCorrect answer: A

Immune checkpoint inhibitors can cause immune-mediated colitis, which may become serious. Prompt assessment of stool frequency, hydration, and associated symptoms, followed by communication with the treating team, supports timely evaluation and management.

Question 2

A patient with cancer who is receiving systemic treatment asks whether they should receive an inactivated influenza vaccine. Which response is most appropriate?

  1. ADiscuss vaccination timing with the oncology team; inactivated vaccines are generally preferred over live vaccines during immunosuppressive treatment
  2. BRecommend a live attenuated influenza vaccine without reviewing treatment status
  3. CState that all vaccines are permanently contraindicated after a cancer diagnosis
  4. DRecommend delaying every vaccine until five years after treatment ends
Show answerCorrect answer: A

Vaccination decisions should account for treatment, immune status, and timing. Inactivated vaccines are generally used rather than live attenuated vaccines in immunocompromised patients, although immune response may be reduced; the oncology team can advise on individualized timing.

Question 3

A patient with cancer and reduced appetite asks how to maintain nutrition during treatment. Which recommendation is most appropriate as an initial approach?

  1. AExplore food preferences and symptoms, and consider small, frequent, nutrient-dense meals with dietitian support
  2. BRequire a strict fasting schedule on treatment days regardless of the regimen
  3. CEliminate all protein-containing foods until appetite returns
  4. DUse high-dose supplements as a replacement for all meals without reviewing them with the care team
Show answerCorrect answer: A

Nutrition support should be individualized and address causes such as nausea, taste changes, pain, or early satiety. Small, frequent nutrient-dense meals and referral to an oncology dietitian can help; restrictive or unsupervised replacement strategies may worsen nutritional risk.

Question 4

A patient with a painful bone metastasis is prescribed oral immediate-release morphine as needed. Which instruction best supports safe use?

  1. ATake each dose at fixed intervals even when pain is absent
  2. BAvoid driving or other activities requiring alertness until the effects are known
  3. CStop the medication as soon as pain improves for one dose
  4. DCrush any tablet to make it act faster
Show answerCorrect answer: B

Opioids can cause sedation and impair reaction time, particularly when starting treatment or changing doses. Patients should avoid hazardous activities until they know how the medicine affects them. Tablets should only be altered if the specific formulation is confirmed safe to do so.

Question 5

A patient with cancer asks whether a newly diagnosed relative should undergo genetic counseling. Which feature most strongly supports referral for hereditary cancer risk assessment?

  1. ASeveral close relatives on the same side of the family had cancer at unusually young ages
  2. BThe patient has seasonal allergies and no known family cancer history
  3. CA distant relative developed cancer late in life, with no other family cases
  4. DThe patient prefers not to discuss family history
Show answerCorrect answer: A

Multiple close relatives with related cancers, particularly when diagnosed at younger-than-usual ages or clustered on one side of the family, can suggest inherited susceptibility and support referral for genetic risk assessment. The detailed pedigree and personal history guide counseling and testing decisions.

Question 6

A patient with cancer requests help understanding a proposed treatment and says the risks are unclear. What should the clinician do first?

  1. AExplore the patient's questions and provide understandable information about options, benefits, risks, and alternatives before obtaining informed consent
  2. BAsk the patient to sign immediately because the treatment plan has already been selected
  3. CTell the patient that discussing alternatives will undermine confidence in the care team
  4. DHave a family member consent instead, even though the patient has decision-making capacity
Show answerCorrect answer: A

Informed consent requires a voluntary decision based on understandable information about the proposed intervention, material risks, expected benefits, and reasonable alternatives. Addressing questions and checking understanding supports patient autonomy and shared decision-making.

Question 7

A patient with cancer has persistent vomiting and abdominal distention. Imaging shows dilated small-bowel loops, and the patient cannot tolerate oral fluids. Which initial management priority is most appropriate?

  1. AStabilize the patient with intravenous fluids and arrange urgent evaluation of the suspected bowel obstruction
  2. BEncourage a high-fiber diet and reassess the next day
  3. CAdminister an oral laxative and discharge the patient
  4. DRecommend small meals and defer assessment unless pain develops
Show answerCorrect answer: A

Vomiting, distention, and dilated bowel loops suggest obstruction with risk of dehydration and other complications. Initial care includes stabilization, typically with intravenous fluids, and urgent evaluation for cause and appropriate management.

Preparation tips

  • For new diarrhea or abdominal cramping during checkpoint-inhibitor therapy, distinguish possible immune-related toxicity from routine treatment effects and consider the need for prompt evaluation.
  • Practice immediate safety priorities for suspected transfusion reactions, including stopping the transfusion and initiating the appropriate response rather than continuing to observe symptoms.
  • Review counseling decisions involving cancer pain, inactivated vaccination during treatment, and anticoagulant management before procedures; focus on patient-specific risks and safe next steps.
  • Work through supportive-care scenarios involving poor appetite, dysphagia, vomiting, and abdominal distention, separating nutrition or swallowing assessment from signs that may require urgent intervention.
  • Use family-history patterns and patient concerns to practice hereditary-risk referral and clear communication that supports informed treatment decisions.
