About the ONCC Certified Breast Care Nurse Examination Exam

Breast care nurses help patients navigate treatment choices while coordinating education and support across the care team. This work includes reviewing prescription drugs, nonprescription products, and supplements for potential treatment concerns; reinforcing safe use of oral anticancer medicines; and responding to questions about chemotherapy, vaccination, and treatment effects. Nurses also assess physical changes after surgery, such as numbness or brief shooting sensations, and explain when symptoms need further evaluation. Patient-centered care involves clarifying who may receive health updates, supporting informed decisions without directing the patient’s choice, and using clear communication when a patient feels hesitant to ask questions. Care may also address fertility preservation before treatment, reconstruction after mastectomy, and the role of palliative care alongside cancer-directed therapy.

Sample Practice Questions

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

Question 1

A patient with breast cancer asks why the oncology team wants to review all prescription medicines, over-the-counter products, and supplements. What is the best explanation?

  1. ATo identify possible interactions, duplications, and effects on treatment safety.
  2. BTo determine whether the patient can avoid all follow-up visits.
  3. CTo verify that every product is manufactured by the same company.
  4. DTo decide which products the patient should discontinue permanently without further discussion.
Show answerCorrect answer: A

A complete medication reconciliation helps the team assess interactions, overlapping effects, and safety concerns during cancer treatment. Patients should report all products and receive individualized guidance before making changes.

Question 2

A patient is scheduled for a mastectomy and asks what to expect from immediate breast reconstruction. Which explanation is most accurate?

  1. AReconstruction can restore breast shape, but it does not recreate a natural breast or guarantee normal sensation.
  2. BReconstruction prevents breast cancer from recurring in the chest area.
  3. CReconstruction is only possible if no radiation therapy is planned.
  4. DReconstruction restores normal sensation in the breast in nearly all patients.
Show answerCorrect answer: A

Breast reconstruction can create a breast mound using an implant or the patient’s own tissue, but it does not restore a natural breast or reliably restore normal sensation. Recurrence risk and radiation considerations should be discussed with the surgical and oncology teams.

Question 3

A patient with breast cancer says, “I don’t understand the treatment plan, but I’m embarrassed to ask the oncologist to explain it again.” What should the nurse do?

  1. ATell the patient the plan is standard and encourage them to sign the consent form.
  2. BOffer to help the patient prepare questions and arrange a discussion with the oncology team before decisions are finalized.
  3. CAsk a family member to make the treatment decision instead.
  4. DAdvise the patient to search online for a treatment plan that seems simpler.
Show answerCorrect answer: B

The nurse can support understanding by eliciting concerns, helping formulate questions, and facilitating a discussion with the treating team. Patients should have an opportunity to understand proposed care and make informed decisions without pressure.

Question 4

A patient with breast cancer says, “I may want to have children later. Could treatment affect that?” Which nursing response is best?

  1. AReassure the patient that breast cancer treatment does not affect fertility.
  2. BEncourage the patient to discuss fertility goals promptly with the oncology team so options can be considered before treatment begins.
  3. CAdvise the patient to postpone all cancer treatment until after attempting pregnancy.
  4. DExplain that fertility preservation is only relevant after treatment is complete.
Show answerCorrect answer: B

Some cancer treatments can affect fertility, and certain preservation approaches may need to be considered before treatment starts. Prompt referral allows the patient to discuss individualized options without assuming that treatment should be delayed.

Question 5

A patient with breast cancer says they are unsure who is allowed to receive updates about their care. What should the nurse do?

  1. AShare information with any relative who calls because family members are involved in care.
  2. BAsk the patient whom they authorize to receive information and follow applicable privacy procedures.
  3. CRefuse to discuss the issue because the patient must decide without help.
  4. DGive the information to the person listed as the patient’s emergency contact in every circumstance.
Show answerCorrect answer: B

The patient’s preferences and applicable privacy requirements guide disclosure of health information. The nurse should clarify whom the patient authorizes and document or follow the organization’s procedures as appropriate.

Question 6

A patient is overwhelmed while deciding among breast cancer treatment options. Which nursing action best supports informed, patient-centered decision-making?

  1. AExplore the patient’s goals and questions, then help clarify options with the care team
  2. BChoose the treatment the nurse considers best and ask the patient to agree
  3. CDiscourage questions so the decision can be made more quickly
  4. DProvide only information about the most aggressive option
Show answerCorrect answer: A

Shared decision-making includes eliciting the patient’s values and goals, supporting questions, and helping the patient understand options in collaboration with the interdisciplinary team. The nurse should not impose a personal preference.

Question 7

A patient taking an oral anticancer medication says, “I sometimes forget doses, so I take two the next day.” Which nursing response is most appropriate?

  1. AAdvise the patient to double every missed dose to maintain the weekly total.
  2. BAsk about the medication-taking routine and direct the patient to follow the product-specific missed-dose instructions or contact the oncology team.
  3. CRecommend stopping the medication whenever a dose is missed.
  4. DTell the patient that missed doses do not matter for oral cancer treatment.
Show answerCorrect answer: B

Missed-dose instructions vary by medication, and doubling a dose may be unsafe. The nurse should assess barriers to adherence and help the patient obtain medication-specific guidance from the prescribing team or approved instructions.

How to use this practice test

The free practice bank contains 50 questions, with up to 20 randomly selected for a session. Use each set to apply breast cancer care concepts to patient scenarios, then review the results shown after the session to identify topics that need closer attention.

Preparation tips

  • Practice explaining why medication reconciliation should include prescriptions, over-the-counter products, and supplements before cancer treatment.
  • Review safe-use teaching for oral anticancer medicines, including what to say when a patient reports missed doses or taking extra doses.
  • Compare nursing responses that support informed treatment decisions, fertility discussions, and patient control over who receives care updates.
  • Review how to explain immediate reconstruction, post-mastectomy sensory changes, and palliative care without overstating what an individual patient will experience.
