A 77-year-old Hispanic Catholic nun (retired) who immigrated to the United States 15 years ago lives alone but in an apartment complex where her biological sister lives as well. She is being discharged home after a hospitalization for congestive heart failure with prescriptions for eight different medications. She is considered at risk for medication misuse due to what potential contributing factors? (Select all that apply.)

A. Language barrier: Limited English proficiency can impair understanding of medication instructions, increasing misuse risk. B. Ethnic background: Cultural beliefs may influence perceptions of medication use, adherence, or preference for alternative therapies. C. Living alone: Living alone can lead to forgetfulness, poor monitoring, and limited support with medication management. D. Religious background: While religious values may influence treatment decisions, Catholicism typically does not conflict with medication use. This factor alone is not strongly linked to misuse.
