No, I don't think a hospital can function effectively without nurses. Nurses are crucial for patient care and monitoring. They give medications and treatments and provide emotional support to patients and their families. They also help doctors by acting as a bridge between them and the patients. Without nurses, the quality of patient care would drop a lot.

Yes, but it would be very difficult. Doctors and other medical staff could take over some of the duties that nurses do, and technology could help with some tasks. But the workload on doctors and other staff would be too much, and patient care would suffer because there wouldn't be enough personalized attention. It would be a temporary and not very good solution.

Partially, some tasks could be outsourced or automated, and volunteers or family members could help with basic care. Telemedicine might reduce the need for in-person nursing. But for critical care and emergencies, skilled nurses are still needed. Their expertise in patient care can't be replaced, and the hospital's efficiency and effectiveness would suffer without them.
