with A+ Graded Answers
How does age-related acidity decline in the stomach affect medication absorption?
Absorption of some medications is affected by age-related acidity declines in the stomach.
How do age-related changes in total body water and serum albumin levels affect medication
distribution?
Age-related changes such as decreased total body water and low serum albumin levels affect
medication distribution, predisposing older adults to toxicity.
How does decreased liver mass and blood flow affect medication metabolism?
Decreased liver mass and blood flow alter medication metabolism, making more medication available
in the bloodstream and predisposing older adults to toxicity.
How does variable renal function due to normal aging affect the elimination of medications?
Eliminating medications by the kidneys is affected by variable renal function due to normal aging.
What are the consequences of declines in neurotransmitters such as acetylcholine and dopamine
associated with normal aging?
Declines in neurotransmitters such as acetylcholine and dopamine associated with normal aging can
lead to increased toxicity.
What are the effects of diseases like Alzheimer's and Parkinson's on neurotransmitter loss?
Diseases like Alzheimer's and Parkinson's cause neurotransmitter loss, compounding the problem and
leading to increased toxicity.
What are the side effects of anticholinergic medications in older adults?
Anticholinergic medications cause dry mouth, urinary retention, confusion, and impaired cognition in
older adults.
What is the purpose of the Beers Criteria?
To decrease inappropriate medication use in the elderly.
What are some common medications included in the Beers Criteria?
Benzodiazepines, first-generation antihistamines, tricyclic antidepressants, and NSAIDs.
What are the risks associated with benzodiazepines?
Cognitive impairment, delirium, falls, fractures, and motor vehicle accidents.
What are the risks associated with first-generation antihistamines?
Confusion, dry mouth, constipation, and other anticholinergic symptoms such as drowsiness,
somnolence, blurred vision, urinary retention, dry mouth, dizziness, constipation, and confusion.
What are the risks associated with tricyclic antidepressants?
