What should clients be advised to do to prevent orthostatic hypotension while using assistive devices?

Clients should be advised to avoid sudden changes of position to prevent orthostatic hypotension, particularly when using assistive devices. This condition occurs when blood pressure drops significantly when a person moves from sitting or lying down to a standing position, often leading to symptoms such as dizziness or fainting. By moving slowly and gradually adjusting their position, individuals can allow their cardiovascular system adequate time to compensate for the change, which helps maintain stable blood pressure and reduces the risk of falls or injuries.

Avoiding rapid shifts can be especially important for those relying on assistive devices, as they may already have mobility limitations that make them more susceptible to balance issues and physical instability. Therefore, educating clients about the importance of making gradual movements is crucial in promoting safety and independence while using their devices.

The other options, such as limiting fluid intake, engaging in vigorous physical activity, or using devices only at night, do not address the underlying issue of managing blood pressure changes effectively and can even exacerbate the risk of falls or other complications.
