Final answer:
To ensure a pharmaceutical dispenser is working correctly, a visual inspection should be conducted, leaks should be checked for, and the product level must be verified.
Step-by-step explanation:
In the context of quality control for pharmaceutical dispensing machines, the three steps to ensure that the dispenser is working properly would likely include a visual inspection, a check for leaks, and verification of the product level.
A visual inspection would involve a cursory examination of the machine for any obvious defects or contaminants. Checking for leaks is essential to ensure that the medicine is not being wasted or contaminating the surrounding environment.
Lastly, verifying the product level is crucial for ensuring that the correct amount of medicine is being dispensed, which is vital for both the safety and efficacy of the pharmaceutical product.
