Healthcare professional who evaluates, treats, and cares for persons with respiratory disorders.

• A. Nurse
• B. Respiratory Therapist (RT)
• C. Pharmacist
• D. Dentist

Answer: (B)

The main idea here is recognizing who specializes in evaluating and treating breathing problems. A respiratory therapist is trained specifically to assess respiratory status, decide on appropriate therapies, and provide care to people with lung or airway disorders. They perform pulmonary evaluations, manage oxygen and ventilator support, administer inhaled medications and airway clearance techniques, monitor responses, and adjust treatments in collaboration with physicians. This focused expertise sets them apart from other roles: a nurse provides broad patient care and monitoring, but not the specialized respiratory therapies; a pharmacist concentrates on medications; a dentist focuses on oral health. Therefore, the best answer is the respiratory therapist.
