What is medication reconciliation?
- A. Comparing the patient's current medication orders to all of the medications actually being taken
- B. The administration of high alert medications that have been ordered on admission to an acute care facility
- C. The completion of an incident report following a variance that resulted in a serious complication
- D. A printout of computerized patient data that identifies the times that all of the ordered medications are to be administered
Correct Answer: A
Rationale: Medication reconciliation is the process of comparing a patient's current medication orders to all of the medications that the patient is actually taking. Administering high alert medications and completing an incident report are not the same as medication reconciliation. A printout of computerized patient data that identifies the times that all of the ordered medications are to be administered is a description of the medication administration record (MAR), not a description of medication reconciliation.

- C. Schedule I medications are only prescribed in monitored units for patient safety.
- D. Schedule I medications are found in antitussives and antidiarrheals sold over the counter.

The physician has asked a nurse to administer a drug intravenously to a patient who is unresponsive. How can the nurse ensure that the drug is administered to the right patient?
- A. By waking him up to ask him his name
- B. By identifying the patient's room number
- C. By checking the patient's wristband
- D. By asking the nursing assistant for the patient's location
Correct Answer: C
Rationale: The nurse should identify a patient by checking his wristband, which has the patient's name. The nurse should not ask the patient to confirm his name, because some patients, particularly those who are confused or have difficulty hearing, may respond by answering yes. Additionally, this patient is unresponsive. The nurse can obtain the patient's location by asking any other member of the health care staff, but should verify the patient's identity by checking the wristband. The nurse should not rely on the patient's room number alone.
