Final answer:
Compounding for injections and other non-oral solutions must be done in a sterile environment, such as a hospital or compounding pharmacy, following strict cleanliness standards and procedures like dilution calculations.
Step-by-step explanation:
Compounding for parenteral, enteral, ophthalmic drops, or irrigating solutions must occur in a sterile environment, such as a hospital pharmacy or a compounding pharmacy that meets specific cleanliness standards to ensure patient safety.
For example, when dealing with hypokalemia, healthcare professionals need a sterile IV bag and a stock solution of KCl to prepare a diluted intravenous solution. Aides must perform a dilution calculation to achieve the proper concentration for safe administration. Choosing the correct route of administration, such as intravenous or parenteral, depends on factors like drug absorption and the desired plasma levels.
