What are the three areas of 4H0X1 duties?

• A. Respiratory Therapy, Pulmonary Laboratory, Cardiology Laboratory
• B. Respiratory Therapy; Pulmonary Laboratory
• C. Cardiology Laboratory
• D. Respiratory Therapy and Cardiology Laboratory

Answer: (A)

The question tests the range of duties for this Air Force health services role, which includes three clinical areas: respiratory care, pulmonary testing, and cardiac diagnostics. Respiratory therapy involves helping patients with breathing problems—administering inhaled medications, delivering airway clearance therapies, providing oxygen support, and monitoring how patients respond to treatment. The pulmonary laboratory focuses on lung function testing, such as spirometry, lung volumes, diffusion capacity, and bronchodilator response, to evaluate and track respiratory conditions. The cardiology laboratory handles heart-related diagnostics, including 12-lead EKGs and stress testing, to assess cardiac function and guide treatment decisions.

Together, these areas show the breadth of the role: supporting patient care across respiratory therapy and enabling important diagnostic information in pulmonary and cardiology labs.
