Final answer:
Automated dispensing machines located on the wards of hospitals or other healthcare facilities provide access to prescription drugs when the institutional pharmacy is closed.
Step-by-step explanation:
When an institutional pharmacy is closed, access to prescription drugs may be made available through the use of automated dispensing machines located in places other than the pharmacy. These machines are commonly found on the wards of hospitals or other healthcare facilities. They are designed to securely store and dispense prescription medications, allowing patients to access their prescribed drugs even when the pharmacy is closed.
