Vinod K. Bhutani, MD, and Ronald J. Wong; October 2017
A newborn with elevated total serum bilirubin (TSB) due to hemolytic disease was placed on a mattress with embedded phototherapy lights for treatment, but the TSB continued to climb. The patient was transferred to the neonatal ICU for an exchange transfusion. The neonatologist requested testing of the phototherapy lights, and their irradiance level was found to be well below the recommended level. The lights were replaced, the patient's TSB level began to drop, and the exchange transfusion was aborted.

Admitted to the hospital for treatment of a hip fracture, an elderly woman with end-stage dementia was placed on the hospice service for comfort care. The physician ordered a morphine drip for better pain control. The nurse placed the normal saline, but not the morphine drip, on a pump. Due to the mistaken setup, the morphine flowed into the patient at uncontrolled rate.

A man with a history of poorly controlled diabetes and pancreatic insufficiency was found unresponsive. Paramedics transported him to the emergency department, where a resident placed a right internal jugular line for access but was unable to confirm placement. The resident pulled the line, opened a second line insertion kit, started over, and confirmed placement with ultrasound. The patient went into cardiac arrest, and a chest radiograph noted a retained guidewire in the pulmonary artery.
