Mosby Protection-Safety Practice Test

Proper lighting is essential because visibility directly affects safety and accuracy in patient care. When lighting is adequate, staff can see hazards such as wet floors, spills, cords, or obstacles, which helps prevent slips and trips. It also supports correct identification of patients and materials; clear lighting makes labels, wristbands, and medication containers easier to read, reducing the chance of misidentification. In procedures, good lighting improves the ability to see anatomical landmarks, instrument placement, and reading measurements or monitor readings, which lowers the likelihood of errors and reduces eye strain. Conversely, poor lighting can create glare or deep shadows that hide important details, increasing risks to patients. So, lighting isn’t just about comfort—it directly protects patients by enabling safer navigation, accurate identification, and precise execution of care.
