Which problem should take priority in the care of an outpatient with AIDS?

A. Skin integrity: While important (especially with KS or immobility), it is often a secondary concern compared to the complexity of the medical regimen. B. Physical mobility: Mobility is important for quality of life, but in the outpatient setting, medical stability depends on treatment. C. Social isolation: This is a significant psychosocial issue, but physiological and management needs usually take priority in nursing care plans. D. Therapeutic regimen management: For an outpatient with AIDS, adherence to Highly Active Antiretroviral Therapy (HAART) is the most critical factor. Failure to manage the regimen leads to drug resistance, opportunistic infections, and disease progression.
