Resumen
A mock urine chemical analysis demonstration was designed for an undergraduate chemistry for health professions course, mainly composed of undergraduate nursing students. This demonstration was presented after a midsemester lecture series on acid–base chemistry, redox reactions, and colorimetry in chemical education and medical diagnostic practices. Chemistry is a first-year core subject in undergraduate health professions (nursing, exercise sciences, premedical, etc.) curricula, making it an important topic for teaching and learning. Here, a demonstration was created to help nursing students visualize the role of acid–base, redox chemistry, and colorimetry, in relation to healthcare diagnostics. Five mock urine sample solutions were made, using “everyday” grocery items and several lab materials, to simulate five patient samples: metabolic alkalosis, muscular degenerative disease, glycosuria/diabetes mellitus, metabolic acidosis, and diabetic acidosis/ketoacidosis. The undergraduate health professions students (127 of 148 polled) were able to learn acid–base and redox chemistry while solving the mystery of a “scenario” urine sample. Additionally, students responded well to this demonstration, with 137 of 148 polled recommending this demonstration for future chemistry for health professions classrooms. These mock urine samples are easy to make and are a cost-effective, student friendly, and engaging way to illustrate acid–base and redox chemistry to undergraduate health professions students. The results of the mock urine sample analysis (using urine diagnostic strips) were reproduced in three separate student groups totaling nearly 170 individuals.
