Question 20

Isopropyl alcohol is the appropriate solution for cleaning a counting tray.

Using isopropyl alcohol effectively disinfects and cleans the counting tray, ensuring that it is free from contaminants that could compromise the integrity of medications being counted.

A) Isopropyl alcohol

This option is correct because isopropyl alcohol is a widely accepted disinfectant that effectively eliminates bacteria and viruses, making it ideal for cleaning surfaces in a pharmacy setting, including counting trays.

B) Povidone iodine

Povidone iodine is primarily used as a surgical scrub or antiseptic but is not typically used for cleaning counting trays due to its staining properties and inability to evaporate quickly, which could leave residue.

C) 0.9% sodium chloride

While 0.9% sodium chloride is a sterile solution used for various medical purposes, it does not possess disinfectant properties and is therefore unsuitable for cleaning surfaces like counting trays.

D) Chlorhexidine gluconate

Chlorhexidine gluconate is an antiseptic effective against certain bacteria but is not recommended for cleaning counting trays as it can leave a residue and is more commonly used for skin disinfection.

Conclusion

Isopropyl alcohol stands out as the best choice for cleaning a counting tray due to its effective disinfectant properties and quick evaporation, preventing residue. The other options either lack suitable disinfectant capabilities or may introduce unwanted residues, making them less appropriate for this purpose.
