Final answer:
Commitment to career planning is signified by earning relevant educational qualifications like a BSN in nursing and seeking mentorship for professional growth and guidance.
Step-by-step explanation:
The activities that represent a commitment to career planning in the context provided include: earning a bachelor's degree (BSN) in nursing, and working with a seasoned mentor. Earning a bachelor's degree indicates a commitment to gaining the necessary credentials and knowledge base for advancement in the nursing profession. Working with a seasoned mentor can offer real-world insights, advice, and guidance for professional development and navigating career choices within the healthcare field. Although introducing evidence-based practice changes and discussing health needs can be part of career growth, they are not strictly career planning activities. Instead, these activities are more reflective of professional development and advocacy within one's current role.
