Which adverse effect is of most concern for older adult clients receiving antihypertensive medications?

The most concerning adverse effect for older adult clients receiving antihypertensive medications is hypotension. Older adults often have a greater risk of experiencing low blood pressure due to factors such as physiological changes associated with aging, polypharmacy, and the presence of comorbid conditions. Antihypertensive medications, which work to lower blood pressure, can exacerbate this risk, leading to symptoms like dizziness, fainting, or falls, which can have significant health implications for this population.

Particularly in older adults, hypotension can result in decreased cerebral perfusion, increasing the likelihood of falls and subsequent injuries. Therefore, careful monitoring and management of blood pressure in older clients on antihypertensive medications are crucial to prevent these adverse effects and ensure their safety and well-being.
