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.

Correct Answer is A
Explanation
A: Providing the client with a diet high in protein is essential for maintaining skin integrity. Protein is crucial for tissue repair and regeneration, which helps prevent skin breakdown and promotes healing of existing wounds.
B: Repositioning the client every 3 hours is less effective than the recommended every 2 hours. Frequent repositioning helps to relieve pressure on vulnerable areas and prevent pressure injuries.
C: Massaging bony prominences is not recommended as it can cause further damage to already fragile skin and underlying tissues. Gentle handling and avoiding pressure on these areas are more appropriate.
D: Applying cornstarch to keep the skin dry is not advisable as it can lead to skin irritation and breakdown. Instead, using moisture-wicking products and maintaining proper skin hygiene are better practices.
