The nurse closely monitors an older adult for signs of medication toxicity. Which physiological change is the reason for the nurse’s action?

Renal dysfunction

Pancreatic impairment

Increased gastric motility

Increased blood volume

Answer and Explanation

The Correct Answer is A

A: Renal dysfunction is common in older adults and can lead to decreased clearance of medications from the body, increasing the risk of toxicity. Monitoring for signs of toxicity is crucial in this population.

B: Pancreatic impairment can affect digestion and insulin production but is not the primary reason for monitoring medication toxicity in older adults.

C: Increased gastric motility is not typically associated with aging. In fact, decreased gastric motility is more common and can affect drug absorption.

D: Increased blood volume is not a common physiological change in older adults. Decreased renal function and changes in body composition are more relevant factors affecting medication metabolism and excretion.
