Which device is used to count and transfer oral solid medications from a stock bottle to a patient's container?

The counting tray is specifically designed for the purpose of counting and transferring oral solid medications, such as tablets or capsules, from a stock bottle to a patient's container. It typically features a flat surface where pills can be easily counted using a counting spatula. The ridged or sloped edge of the tray allows for easy pouring of the counted medications into the appropriate container, ensuring accuracy and efficiency in the dispensing process.

While a pill cutter is useful for splitting tablets, and a medication spatula aids in the transfer of medications, neither is primarily used for counting and transferring multiple solid dosage forms. A medication dispenser may assist in organizing or distributing medications but does not serve the specific function of counting and transferring from a stock bottle. Thus, the counting tray stands out as the correct choice for this task, highlighting its central role in pharmacy practice for accurate medication dispensing.
