The Drip/Late Shift
(2017, originally 2005-2006) 8 pages, 5.5"x8.5", some full-color and some black & white.
This slender minicomic collects two earlier nursing-related stories: "The Drip" (from Not My Small Diary), a true story of the author's own incompetence in a hospital setting, and "Late Shift" (from An Inside Job, with added color), in which nurses aren't allowed to quit even in the afterlife.
Besides the paper version, the stories are also online (b&w only) here and here.
