Question

Why are geriatric patients more likely to have an adverse reaction to vasodilator drugs?

a) Decreased sensitivity to medications
b) Increased drug metabolism
c) Altered baroreceptor function
d) None of the above

Answer 1

Geriatric patients are more likely to have an adverse reaction to vasodilator drugs due to decreased sensitivity to medications and altered baroreceptor function.

Step-by-step explanation:

Geriatric patients are more likely to have an adverse reaction to vasodilator drugs due to decreased sensitivity to medications. As people age, their bodies may become less responsive to the effects of medications, including vasodilators. This decreased sensitivity can lead to a higher risk of adverse reactions.

In addition, geriatric patients may also experience altered baroreceptor function, which can further increase the likelihood of adverse reactions to vasodilators. Baroreceptors are specialized cells that help regulate blood pressure, and when they are not functioning properly, the body's response to vasodilator drugs may be unpredictable.

Increased drug metabolism is not typically associated with increased risk of adverse reactions to vasodilator drugs in geriatric patients. Instead, it is more commonly seen in younger individuals who metabolize drugs at a faster rate.
