Final answer:
The nurse is preparing for the expanded role of a Clinical Nurse Specialist (CNS) (option 1) in geriatric nursing, which requires significant education and aligns with rising healthcare demands due to the aging population.
Step-by-step explanation:
The nurse who is planning to pursue further education to become an expert in geriatric nursing who carries out direct care is preparing for the role of a Clinical Nurse Specialist (CNS). A CNS is an advanced practice nurse who can provide expert advice related to specific conditions or treatment pathways. Given the aging population and the expected increase in the demand for healthcare services related to elder care, such as geriatric nutrition and home healthcare nursing, pursuing a career as a geriatric CNS will align with the trends in the healthcare labor market. Social changes like the Affordable Care Act have increased the demand for healthcare services, making professions like that of a CNS essential for meeting the healthcare needs of the aging population, particularly the baby boomers. This career path requires significant education and training but tends to be a lucrative choice.
