Final answer:
Limited access to healthcare due to immigration status is the most concerning issue for abuse of a 70-year-old immigrant farmworker. This issue can lead to increased vulnerability to abuse and mistreatment, considering factors like exploitation and support system deficiencies.
Step-by-step explanation:
Among the concerns for a 70-year-old recent immigrant working as a farmworker in the U.S. and experiencing persistent headaches, the most concerning issue for abuse would be limited access to healthcare services due to immigration status (Option B). While language barriers (Option A), occupational hazards (Option C), cultural expressions of pain (Option D), and social isolation (Option E) are significant, lack of healthcare access is a critical aspect that can be directly linked to an increased risk of abuse and mistreatment. Based on research like Snipes et al., and other factors such as vulnerability to exploitation, this issue would be of most concern.
Studies such as those conducted by Snipes et al. (2007) on stress among Mexican immigrant farmworkers highlight work-related stressors including injustice in work conditions and cultural adjustment. Elderly individuals have specific vulnerabilities, including the increased likelihood of abuse by caregivers, especially when isolated or subject to high stress and lack of support, as identified by Kohn and Verhoek-Oftedahl (2011).
