Final answer:
In treating delirium, frequent reorientation, encouraging mobility, and removing tethers are helpful, whereas not letting the family stay at night is not a recommended practice and may not be beneficial.
Step-by-step explanation:
The ways to treat delirium include frequent reorientation, keeping the door open during daytime to orient the patient to the time of day, encouraging mobility to maintain function and prevent deconditioning, and removing tethers (such as catheters or restraints) that can cause confusion or agitation. However, not letting the family stay at night may not be helpful and is not generally a recommended practice in the treatment of delirium. Family presence can be reassuring to patients and help with reorientation and reducing anxiety.
