Rasmussen was a nurse manager of the coronary care (critical care) unit at UCLA Medical Center, where she was considered an expert clinician and leader in the care of cardiac and critical care patients, exerting her influence over clinical practice through her leadership, publications, and presentations. She went on to become nursing director of the critical care units at Glendale Adventist Medical Center, a position she held when, tragically, she was murdered in 1986. She was a tireless advocate for patients, ensuring that they received the highest-quality professional and compassionate care possible. Rasmussen’s leadership and guidance created an environment in which there was a sense of common purpose, high morale and teamwork. Whether delivering care herself or supervising others, she was dedicated to the highest principles of nursing practice. Rasmussen, who entered college at age 16, was described as “brilliant” by her peers at the UCLA School of Nursing, where she obtained her master’s. She also taught at the school and lectured internationally on critical care nursing.
