A 66-year-old with severe COPD stabilizes after an exacerbation, still walks 120 feet before severe dyspnea, uses inhalers incorrectly, smokes half a pack daily, lives alone, and has no follow-up or action plan. Which outpatient discharge and rehabilitation plan best supports long-term chronic lung management?

The plan with pulmonary rehabilitation, inhaler teaching, smoking cessation, and early follow-up is the best listed choice for this patient’s severe exertional limitation, incorrect device use, ongoing smoking, and lack of follow-up. Rehabilitation provides graded exercise, breathing retraining, and psychosocial support to improve tolerance and reduce readmission beyond simple activity advice. Inhaler teaching helps ensure medication reaches the lungs, while smoking cessation slows decline and reduces exacerbations; early review supports treatment optimization. A plan with rehabilitation, smoking cessation, an action plan, and early follow-up omits inhaler retraining, so incorrect technique may continue to limit drug delivery despite adherence. A plan with rehabilitation, inhaler teaching, an action plan, and early follow-up omits cessation support, leaving ongoing smoking to sustain airway inflammation and undermine gains. A plan with inhaler teaching, smoking cessation, an action plan, and early follow-up omits supervised rehabilitation, despite severe dyspnea that calls for monitored progression and dyspnea management. Exam caveat: near-complete plans are intentional traps, so check which stem needs each option addresses; the keyed plan does not include an action plan. Practical check: use inhaler teach-back, confirm the rehabilitation referral, support a quit date and pharmacotherapy, and book follow-up within weeks to review a written action plan.
