Final answer:
Option C: Water used in compounding must be purified, ensuring the removal of contaminants. Antiseptics are used on tissues for microbial control. Potable water is safe to drink but not necessarily pure enough for compounding.
Step-by-step explanation:
The water used in compounding must be purified. This ensures that any potential contaminants that could interfere with the compound being made are eliminated. Purified water has been processed to remove impurities such as chemicals, biological contaminants, and suspended solids, making it suitable for use in pharmaceutical preparations and laboratory settings.
Antiseptics are suitable for use on living tissues for microbial control to prevent infection. Items like pre-sterilized glass or plastic graduated pipettes are used to transfer sterile liquids. They are essential for maintaining the sterility of the solutions being handled in laboratory environments.
The term potable water refers to water that is clean enough to drink safely and does not contain harmful levels of chemical pollutants or microorganisms. Although potable water is generally safe for consumption, it may not necessarily meet the sterility or purity requirements for compounding pharmaceuticals or laboratory procedures, where purified water is necessary.
