Answer: (C)

Verified step by step guidance

1. Step 1: Begin by analyzing the problem and identifying the context. The question is asking about a treatment that helps patients breathe more easily, which is related to respiratory support.
2. Step 2: Review the options provided: antibiotics, insulin, oxygen therapy, and intravenous fluids. Consider the physiological effects of each option and how they relate to breathing.
3. Step 3: Understand the role of oxygen therapy. Oxygen therapy involves delivering supplemental oxygen to patients who have difficulty breathing due to conditions like hypoxemia, COPD, or pneumonia. It directly supports respiratory function.
4. Step 4: Eliminate the other options based on their primary functions: antibiotics treat infections, insulin regulates blood sugar levels, and intravenous fluids maintain hydration and electrolyte balance. None of these directly assist with breathing.
5. Step 5: Conclude that oxygen therapy is the correct answer because it specifically addresses the need to help patients breathe more easily by improving oxygen delivery to the lungs and tissues.
