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.

Correct Answer is C

Explanation

A: Keeping a fluorescent ceiling light on at night can be too bright and disrupt sleep. A nightlight is a better option for safety without disturbing sleep.

B: Keeping the walker at the end of the bed is not ideal. The walker should be within easy reach to prevent falls when getting out of bed.

C: Placing a bath seat in the shower is a good safety measure. It provides stability and reduces the risk of slipping and falling while bathing.

D: Placing an area rug at the entry of the bathroom can be a tripping hazard. It is better to use non-slip mats that are securely placed.

A. “I have a small snack and take a bath before going to bed each day.” B. “I go to bed and get up routinely at the same time each day.” C. “I watch television until I fall asleep at night.” D. “I don’t take naps throughout the day.”

Correct Answer is C

Explanation

A: Having a small snack and taking a bath before bed can promote relaxation and improve sleep quality.

B: Going to bed and getting up at the same time each day helps regulate the body’s internal clock and promotes better sleep.

C: Watching television until falling asleep can interfere with sleep quality. The light from screens can disrupt the production of melatonin, a hormone that regulates sleep.
