Final answer:
The nurse manager should instruct staff to use the downtime documentation process as described in the facility policy when the computers are unavailable during the shift.
Step-by-step explanation:
If a nurse manager is informed that the computers will be unavailable for four hours during the shift, the most appropriate action to instruct the nursing staff would be to follow Option D: Use the downtime documentation described in facility policy. Each healthcare facility should have a contingency plan for electronic documentation system failures that include manual or offline recording methods. These predetermined procedures are designed to ensure patient care is documented accurately despite technological disruptions.
Following facility policy, the staff should make written notes or use a paper charting system as specified in the protocol to record patient care during the downtime. It is essential that nurses document patient care as close to real-time as possible to maintain accuracy and continuity of care. Once the computer systems are back online, these notes can be entered into the electronic health record promptly in accordance with the facility's recovery procedure.
