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
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.

Explanation
A: Cleaning hearing aids with alcohol wipes is not recommended as it can damage the devices. The client should use a soft, dry cloth or a cleaning tool designed for hearing aids.
B: Expecting the hearing aids to whistle when cupping a hand over them is normal. This feedback occurs due to the sound being reflected back into the microphone.
C: Not using hairspray while wearing hearing aids is correct. Hairspray can clog the microphone and other components of the hearing aids.
D: Changing the batteries once a week is a reasonable practice, depending on the usage and type of hearing aids. This statement does not indicate a need for further instruction.
