Final answer:
Permanent markers should be used to write on count sheets and tray lists because they provide a durable and smudge-resistant way to maintain legible and unaltered records critical in healthcare settings.
Step-by-step explanation:
When working with count sheets and tray lists in a healthcare or clinical setting, it is important to use writing instruments that ensure the information remains legible and unaltered through various conditions. In this context, the recommended option to use for writing on count sheets and tray lists would be c) Permanent markers.
Permanent markers are preferred because they provide a lasting record that is resistant to smudging, water damage, and other environmental factors that could cause the ink to run or become illegible. Regular ink pens may not provide the same level of durability, and their ink can easily be smeared if the count sheets come into contact with moisture. Pencils are also not suitable as they can be easily erased or smudged, leading to inaccurate count data. Water-based markers, like regular ink pens, are susceptible to smudging and are not waterproof.
Therefore, permanent markers are generally the best choice for ensuring that the information recorded on count sheets remains clear and reliable over time, which is essential in maintaining accurate inventory and tracking records within a healthcare environment.
