According to College of Nurses of Ontario, “Each jurisprudence examination consists of 50 multiple-choice questions.”[1]
Prepare for the CNO - College of Nurses of Ontario exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: A nurse has been charged with an offence under the Criminal Code of Canada that is unrelated to their nursing practice. According to the Regulated Health Professions Act, 1991, what is the nurse's reporting obligation to the CNO?
Answer: D. The nurse must self-report the charge in writing to the CNO.
Explanation:
The correct answer is D. A nurse charged with an offence must report it to the CNO in writing, and this applies even when the charge has nothing to do with nursing practice.
A is wrong because the duty is personal. An employer cannot take it over. B is wrong because the duty begins at the charge and does not wait for a guilty finding. C is wrong because the workplace connection does not decide whether you must report.
Rule to remember: reporting duties to the regulator belong to the nurse, and they are triggered by the charge itself, not by the outcome or the setting.
Question: During a head-to-toe assessment, a CNO-registered nurse notes that a client has unequal pupils. What is the nurse's priority action?
Answer: B. Notify the physician immediately as this may indicate a neurological emergency
Explanation:
The correct answer is B. Unequal pupils can point to a neurological emergency such as raised pressure inside the skull, so the physician needs to hear about it immediately.
A is wrong because documenting and carrying on delays action on a possible emergency. C is wrong because pain medication does not address the finding and could hide further changes. D is wrong because waiting to reassess leaves a possibly deteriorating client unattended.
Rule to remember: a new, unexpected finding that may threaten life or neurological function calls for immediate escalation. Document it afterwards.
Question: According to the CNO's Code of Conduct, what is the primary accountability of a nurse when they identify a conflict between their personal beliefs and a client's care plan?
Answer: C. To provide safe, compassionate, and timely care until other arrangements are made.
Explanation:
The correct answer is C. When personal beliefs conflict with a care plan, the nurse keeps providing safe, compassionate and timely care until other arrangements are in place, so the client is not left without service.
A is wrong because handing the client over immediately can leave a gap in care. B is wrong because it focuses on the nurse's conflict and puts the client's needs second. D is wrong because documenting and consulting an ethics committee may be useful, but neither is the primary accountability.
Rule to remember: the client's well-being comes first, and care must continue without interruption while the conflict is resolved.

A client writes to the College of Nurses of Ontario (CNO) stating that a nurse assaulted him during care. What action may CNO take in this situation?
Answer: B. Investigate the allegation
Explanation: When a client reports an allegation of assault by a nurse, the appropriate action for the College of Nurses of Ontario (CNO) is to investigate the allegation. The CNO is responsible for investigating complaints against nurses to ensure the safety and well-being of the public. This investigation process involves gathering information, interviewing relevant parties, and determining whether disciplinary action or further steps are necessary to address the complaint. Referring the complaint to the nurse's employer, requesting employment termination, or involving law enforcement may occur depending on the outcome of the investigation and the severity of the allegation, but the initial step is to investigate the allegation internally.
Which of the following responsibilities falls exclusively under the mandate of the College of Nurses of Ontario (CNO)?
Answer: C. Establishing requirements for entry to practice to ensure public safety.
The CNO's primary mandate, as dictated by provincial legislation, is to protect the public. [29] This is achieved by regulating the nursing profession, which includes setting the standards and requirements for individuals to enter the profession. [4, 29] Advocating for nurses' working conditions and negotiating salaries are roles of a union, like the Ontario Nurses' Association (ONA), while offering liability protection and other professional development are often functions of a professional association, like the RNAO. [29, 32]
Who holds the highest priority as a substitute decision maker (SDM) for an incapable adult under Ontario's Health Care Consent Act hierarchy?
Answer: C. Court-appointed guardian of the person with treatment authority
A court-appointed guardian of the person who has been granted authority to make treatment decisions ranks highest in the HCCA substitute decision maker hierarchy.
Which body in Ontario has the authority to review findings of incapacity made by health practitioners and resolve disputes between substitute decision makers and healthcare providers?
Answer: C. The Consent and Capacity Board
The Consent and Capacity Board is an independent tribunal that reviews capacity findings, resolves SDM disputes, and can authorize treatment in certain circumstances.
