Scenario #1: The nurse prepares medication for one of the patients in Room 102. After administering the medication, the nurse realizes the meds were given to the wrong patient. The nurse immediately reports the incident to the physician. Following this action, the nurse returns to the patient's room and informs and assesses the patient. The nurse completes an occurrence report and continues to monitor the patient for adverse reactions.

Scenario #2: Dante is the charge nurse on a busy medical floor. He has been informed by administration that his unit had failed to document adequately the weights of patients with CHF. Dante creates a new procedure for this documentation. He posts copies explaining the change in the break room. An in-service is conducted at 2:00 pm that day to explain further the importance of following the procedure. Dante assumes that the procedure is being followed. At the end of 3 months, Dante is surprised when his supervisor reveals the statistics. There was increased compliance in the week following the in-service, but within a few weeks, documentation had slipped to even lower levels than previously noted.
