You are the VP for the cardiovascular service line at a hospital. A nurse manager on the step-down-unit tells you about a study she just read that she thinks could benefit her floor. According to her, the study says that if the song "Marry had a little lamb" is played when a patient at risk for falls tries to get out of his chair or bed, nurses are more likely to respond to this cue than to the patient call alarm. The reason is the song is found to be irritating and the nurse wants it to stop. The only way the song will stop is if the nurse acknowledges the alarm from the patient's room. She believes that if this idea is implemented, the floor could potentially decrease fall rates and associated costs.
