Final answer:
Among the factors listed, adequate financial resources is the one that does not impair nutrition, as it allows access to a nutritious diet, unlike the others, which are health-related issues that affect eating abilities.
Step-by-step explanation:
All of the following are factors that can impair nutrition EXCEPT adequate financial resources.
1) Diagnosis of Parkinson's disease, due to symptoms like difficulty in swallowing and the potential for dementia, can contribute to malnutrition as individuals may struggle with ingestion and digestion of food.
2) History of stroke can lead to physical disabilities that may impede the ability to prepare and consume food, which can impair nutrition.
3) Use of antipsychotic medication can often have side effects such as weight gain or loss and metabolic changes, which can affect nutrition.
Factors such as stress, diet choices, underlying diseases, and socio-economic conditions all play a role in nutrition. Therefore, among the options provided, adequate financial resources do not impair nutrition; rather, they may provide the means for accessing a diverse and nutritious diet.
