Final answer:
A medical assistant should flush their eyes for 15 to 20 minutes with clean water or saline solution after a splash exposure to a chemical or hazardous material.
Step-by-step explanation:
The question on how long a medical assistant should flush their eyes after a splash exposure is related to workplace health and safety procedures. In the context of hazardous materials or chemical exposure, industry standard safety guidelines recommend flushing the affected eye area for 15 to 20 minutes with clean water or saline solution immediately after exposure. This duration is crucial to effectively remove the contaminant and minimize potential damage to the eye tissues. It's important to note that while the reference text discusses the adaptation of the human eye to darkness, the information doesn't directly pertain to eye flushing protocols following chemical exposure.
