Final answer:
When a pharmacist must leave the premises, the pharmacy can either hire a temporary pharmacist or close temporarily. Hiring a temporary pharmacist ensures the continuity of pharmaceutical care, while closing temporarily may inconvenience patients but ensures patient safety.
Step-by-step explanation:
When a pharmacist must leave the premises, the pharmacy has two options. One option is to hire a temporary or relief pharmacist who can take over the duties in their absence. This ensures that there is still a licensed professional present to dispense medications and provide necessary guidance to patients. Another option is to close the pharmacy temporarily until the pharmacist returns. This may inconvenience patients, but it ensures that proper pharmaceutical care is maintained.
