Which action is the priority during treatment of a patient with breathing difficulty and wheezing who is not yet severely hypoxic?

• A. administer oxygen
• B. assist ventilation
• C. call medical command
• D. reassure the patient only

Answer: (A)

The main idea here is to ensure the patient’s oxygen supply is adequate. In a person with breathing difficulty and wheezing, giving supplemental oxygen right away helps prevent hypoxemia as you evaluate and treat the underlying cause. Even though the airway is narrowed and wheezing is present, oxygen won’t worsen the situation and it buys time to improve oxygen delivery to tissues while bronchodilators or other therapies are administered. Start with a steady flow of oxygen using the appropriate device (typically a nasal cannula first, escalating to a non-rebreather if the patient’s saturation remains low or they’re in significant distress). Continuously monitor the oxygen saturation and work of breathing. If signs of ventilatory failure appear—inadequate breaths, fatigue, decreasing tidal volume, altered mental status—you would then move to assisted ventilation. Reassuring the patient is helpful, but it doesn’t address the critical need to oxygenate. Medical control can be contacted for orders, but the immediate priority is to administer oxygen.
