A 13-year-old male has a cough with an inspiratory whoop and an SpO2 of 93%. What should you do next?

In this scenario, the patient exhibits signs that suggest a respiratory issue commonly seen in conditions such as pertussis, indicated by the "inspiratory whoop" associated with coughing. His oxygen saturation level of 93% indicates that he is hypoxic and may require supplemental oxygen to improve his oxygenation.

Administering oxygen by nasal cannula is appropriate as it provides immediate support for the patient's oxygen needs. By increasing the amount of oxygen available for the patient, the goal is to improve his saturation levels, potentially alleviating hypoxia and supporting his respiratory function until further evaluation and treatment can be provided.

While other interventions, such as assisting ventilations or administering medications like beta antagonists or agonists, may be relevant in specific situations, ensuring the patient's oxygen supply is generally the priority when a patient presents with low oxygen saturation. This step is crucial to prevent further complications as you continue to assess and manage the patient’s overall respiratory condition.
