CNO - College of Nurses of Ontario Safe Medication Administration Questions and Answers

Question 1

A nurse is preparing to administer a high-alert medication that requires an independent double check. Which of the following actions best represents a true independent double check according to the Institute for Safe Medication Practices (ISMP) and CNO's principle of safety?

Accepted Answer

The first nurse prepares the medication, and the second nurse performs their own separate check of the order, calculation, and preparation before comparing results.

Answer

A true independent double check requires two clinicians to separately and individually check all components of the medication use process (e.g., order, dose calculation, pump settings). This prevents one nurse's potential error from influencing the other's assessment. The other options describe forms of checking that are not independent and can lead to confirmation bias.

Question 2

A physician gives a nurse a telephone order for a new medication. To comply with the CNO's Medication practice standard, what is the most critical action the nurse must take after transcribing the order?

Accepted Answer

Read the order back to the prescriber for verification.

Answer

The CNO's standards emphasize clear communication to ensure safety. When taking verbal or telephone orders, the nurse is accountable for accurately recording the information and must read it back to the prescriber to verify its correctness and prevent errors. While having a colleague review it is good practice, the direct confirmation with the prescriber is the most critical step.

Question 3

A nurse discovers they administered a medication to the wrong client. After assessing the client and ensuring their immediate safety, what is the nurse's next accountability according to the CNO's standards?

Accepted Answer

Notify the prescriber and the nursing manager of the error.

Answer

After ensuring client safety, the nurse's accountability is to report the medication error to the appropriate individuals, which includes the prescriber and the nurse's manager. This facilitates timely intervention and management of the client's health and initiates the necessary follow-up and quality improvement processes. Documentation and incident reports are also required but follow notification.

Question 4

A competent client with a history of hypertension refuses their scheduled dose of metoprolol, stating, "I feel fine today and I don't want to take it." Which action by the nurse demonstrates accountability and respect for the client's right to refuse?

Accepted Answer

Documenting the refusal on the MAR and notifying the prescriber of the missed dose.

Answer

According to the CNO standards and the 10 Rights of Medication Administration, clients have the right to refuse medication. The nurse's professional accountability is to respect the competent client's decision, withhold the medication, document the refusal accurately, and inform the prescriber. This ensures the care team is aware of the situation and can make any necessary adjustments to the plan of care.

Question 5

When performing the three checks of medication administration, the nurse reads the medication administration record (MAR), retrieves the medication, and compares it to the MAR. What is the essential third check the nurse must perform?

Accepted Answer

Comparing the medication label to the MAR one last time at the client's bedside.

Answer

The three checks are a fundamental safety process. The first check is when retrieving the medication, the second is when preparing it, and the crucial third check occurs at the client's bedside, comparing the medication label against the MAR just before administration. This final check confirms the 'five rights' at the point of care, minimizing the risk of error.
