Step-by-step explanation:
No, nursing assistants are not responsible for starting oxygen therapy. Starting oxygen therapy is typically the responsibility of respiratory therapists. Respiratory therapists specialize in evaluating and treating patients with lung and cardiovascular diseases. They work as part of a medical team to develop treatment plans and may operate advanced equipment like ventilators and blood gas analyzers. Nursing assistants focus on providing general patient care, which may include tasks like assisting with bathing, dressing, and feeding patients.
