When administering dimenhydrinate to an older adult client, what is the nurse's priority intervention?

When administering dimenhydrinate to an older adult client, protecting from injury is the priority intervention due to the potential side effects associated with this medication, particularly sedation and dizziness. Older adults are often more sensitive to the central nervous system effects of antihistamines like dimenhydrinate, which can lead to an increased risk of falls and other injuries.

Dizziness and impaired coordination can occur, increasing the likelihood that an older adult may experience a fall, especially if they attempt to get up or move about unassisted. Therefore, ensuring a safe environment and minimizing the risk of injury is critical. This can include guiding the patient when moving, ensuring they have sturdy support, and checking that the living area is free of hazards that could cause a fall.

While monitoring blood pressure, encouraging fluid intake, and providing a warm environment are also important aspects of care, the immediate risk of injury from falls due to sedation and dizziness takes precedence in this scenario.
