When should patients be re-assessed for fall risk?

Patients should be re-assessed for fall risk under specific circumstances that can affect their mobility and overall safety. The correct choice emphasizes that reassessment is particularly important in situations that could impact a patient's risk of falling.

When a patient is transferred to another unit within a facility, they may encounter new environments or changes in their care, which could affect their mobility and balance. This new setting may expose them to different hazards or necessitate adjustments to their care plan, making reassessment crucial.

The use of mobility devices is another significant factor. When a patient starts using a mobility aid, such as a walker or cane, their gait, balance, and need for assistance may change. This alteration in their mobility strategy should prompt a reassessment to ensure their safety and to determine if additional support or modifications are needed.

While family visits can provide social support, they do not typically affect the patient's physical condition or mobility in a way that would necessitate immediate fall risk reassessment. Therefore, the emphasis on reassessing in the other two situations, while excluding family visits, confirms a pragmatic approach to ensuring patient safety.
