Code Blue - Emergency
James White
 The protagonist of the story is Sommaradvan healer Cha Thrat. She bravely saved a human pilot who crashlanded on her planet, despite a complete lack of knowledge about his physiology. Contact with her species was established by the accident, so knowledge of their social customs is still virtually non-existent. However, she is invited to join the Sector General staff. Cha Thrat innocently wreaks havoc by following her instincts and social customs. First she befriends a hypochondriac Chalder. Next, she is invited to assist at a therapeutic surgery operation to amputate the limb of a Hudlar, which will prolong its life (see Star Healer.) When given the honor of cutting the limb, she obliges - and then deliberately cuts her own arm off as well, in accordance with the custom of her people. Next she saves the untouchable patient Khone (see Star Healer), and then finds a weird parasite species on a derelict spaceship. Due to the chaos she causes, every department in the hospital now refuses to allow her near their patients. O'Mara values her unusual approaches, and decides to add her to his staff.
