In this case, the nurse failed to promote due diligence and this resulted in the full cardiac and respiratory arrest of the patient. Here, Judy is a patient with acute depression and suicidal ideation and hence, she needed high quality patient care. However, the nurse did not meet the standards of quality care. To illustrate, the nurse did not notice the psychiatrist leaving the room and she was not cautious about the possibility of danger with the bathroom that had kept unlocked. Similarly, the psychiatrist neglected to inform the nurse that Judy was alone in the room. Evidently, the negligence of the nurse and the psychiatrist (ethically) compromised patient safety in this regard. The nurse was negligent for unlocking the bathroom door and allowing Judy to shower herself. The case study clearly indicates that Judy had high suicidal tendency and hence, she was admitted in a 24-hour emergency mental health unit. She made a suicide attempt there and was subsequently moved to a 15 minute observation protocol. It clearly reflects that Judy was extremely prone to suicidal thoughts so she might make another suicide attempt at any time. The psychiatrist might not notice that the bathroom door had been unlocked as it was not her responsibility.
