A nurse is reviewing the medication list of an older adult client who takes several medications for different health problems.
The nurse recognizes that polypharmacy in older adults can increase the risk of which of the following?
Adverse drug reactions.
Medication adherence
Drug-drug interactions.
Therapeutic effects.
The Correct Answer is A
The correct answer is A.
Adverse drug reactions.
Polypharmacy, which refers to the effects of taking multiple medications concurrently to manage coexisting health problems, is common among older adults.
It is defined as the regular use of at least five medications.
Polypharmacy can lead to an increase in geriatric syndromes, decrease in functional outcomes, and increased mortality.
One of the major risks of polypharmacy is adverse drug reactions, which are harmful or unintended effects of a medication that occur at normal doses.
Adverse drug reactions can result from drug-drug interactions, drug-disease interactions, drug-age interactions, or inappropriate prescribing.
Adverse drug reactions can cause symptoms such as confusion, dizziness, falls, bleeding, or organ damage.
They can also lead to hospitalizations, increased health care costs, and reduced quality of life.
Choice B is wrong because medication adherence, which is the extent to which patients take medications as prescribed by their health care providers, can actually decrease with polypharmacy.
This is because taking multiple medications can be complex, costly, and burdensome for older adults, especially if they have cognitive impairment or low health literacy.
Medication adherence can also be influenced by patients’ beliefs, preferences, and expectations about their medications.
Choice C is wrong because drug-drug interactions are not a risk of polypharmacy per se, but rather a cause of adverse drug reactions.
Drug-drug interactions occur when two or more drugs affect each other’s pharmacokinetics (absorption, distribution, metabolism, excretion) or pharmacodynamics (mechanism of action, efficacy, toxicity).
Drug-drug interactions can alter the therapeutic effects or safety of a medication.
Choice D is wrong because therapeutic effects are the intended or desired effects of a medication that benefit the patient’s health condition.
Therapeutic effects can decrease with polypharmacy due to drug-drug interactions that reduce the efficacy of a medication.
Therapeutic effects can also be diminished by prescribing cascade, which is a phenomenon where a new medication is prescribed to treat a symptom that is actually an adverse drug reaction of another medication.

Correct Answer is C
Explanation
The correct answer is C.
Living arrangements and social support.
This is because living arrangements and social support are some of the environmental factors that can influence the psychosocial changes in older adults.Psychosocial changes refer to the changes in mental and emotional well-being, social relationships, and roles that occur as people age.Environmental factors are the external conditions or circumstances that affect a person’s life.
Choice A is wrong because physical health and functional status are not environmental factors, but rather biological factors that affect the aging process.Physical health and functional status can influence the psychosocial changes in older adults, but they are not part of the environment.
Choice B is wrong because cognitive conditions and memory loss are also not environmental factors, but rather neurological factors that affect the brain function of older adults.Cognitive conditions and memory loss can also influence the psychosocial changes in older adults, but they are not part of the environment.
Choice D is wrong because hormonal changes and sensory impairments are also not environmental factors, but rather physiological factors that affect the body function of older adults.Hormonal changes and sensory impairments can also influence the psychosocial changes in older adults, but they are not part of the environment.
Living arrangements and social support are environmental factors because they depend on the availability, accessibility, and quality of housing, transportation, community services, family networks, and social interactions that older adults have in their surroundings.Living arrangements and social support can influence the psychosocial changes in older adults by affecting their sense of independence, identity, belonging, security, and satisfaction.
Therefore, living arrangements and social support are some of the environmental factors that can influence the psychosocial changes in older adults.
