Final answer:
A Class H pharmacy must not allow the misuse or theft of controlled substances and must ensure all medication dispensed is safe and has not been altered, as such actions can lead to severe patient harm.
Step-by-step explanation:
A Class H pharmacy, which is typically involved in hospital or clinical settings, should adhere to strict protocols to ensure patient safety and maintain compliance with healthcare regulations. In light of the presented scenario, a Class H pharmacy must not engage in the practice of allowing employees to misuse or steal controlled substances, such as syringes of painkillers.
It is imperative for pharmacies to have systems in place to prevent drug diversion and to ensure that all dispensed medication is safe and unaltered. The incident where a healthcare worker, dealing with addiction, was caught stealing and replacing syringes, leading to patients contracting HIV, highlights the grave consequences of such negligence. Therefore, a Class H pharmacy should not perform any activities that compromise drug integrity or patient health.
