concerns, overcome resistance behaviors, manage transference (patient unconsciously redirects feelings from past significant person onto nurse) and countertransference (nurse unconsciously redirects feelings onto patient—seek supervision, self-awareness), facilitate behavior change, promote problem-solving), termination phase (review progress toward goals, reinforce gains, discuss feelings about ending relationship, summarize accomplishments, provide referrals if needed, plan for follow-up), boundaries in therapeutic relationships (professional boundaries (therapeutic purpose, clear roles, time-limited, focus on patient needs), boundary violations (excessive self-disclosure, secrecy, role reversal, dual relationship (friend, family, business partner, romantic/sexual relationship—NEVER
