Final answer:
Not all institutional pharmacies are required to be open 24/7; operating hours vary depending on their services and local regulations.
Step-by-step explanation:
The statement that institutional pharmacies must be open 24 hours per day, 7 days per week is false. While some institutional pharmacies, particularly those located in hospitals or emergency care facilities, may operate around the clock to serve patients, not all institutional pharmacies are required to be open continuously. Regulations and operating hours can vary depending on the specific type of institutional pharmacy, the services it provides, and the regulations of the state or country in which it operates. It is important to note that some institutional pharmacies have set operating hours and utilize on-call services or automated systems to handle after-hours needs.
