EMT Airway and Breathing Practice Exam

In the scenario described, the immediate action that is most appropriate is to administer high-flow oxygen and assess the adequacy of her breathing. The woman's acute shortness of breath, coupled with pale skin and anxiety, suggests a potential respiratory emergency that could be caused by various conditions, such as pulmonary embolism, pneumonia, or acute asthma exacerbation.

Providing high-flow oxygen is crucial because the patient's symptoms indicate she may be experiencing hypoxia, a lack of sufficient oxygen in the tissues. Administering high-flow oxygen helps quickly increase the oxygen saturation in her blood, which is critical for sustaining her vital organs and preventing further complications.

As you administer the oxygen, simultaneously assessing the adequacy of her breathing is vital. Observing her rate, depth, and effort of breathing will provide necessary information regarding her respiratory status. This dual action allows for a more informed response, ensuring that if her breathing is inadequate, further interventions, such as assisted ventilation, can be initiated promptly.

In contrast, while administering low-flow oxygen and performing a rapid assessment are also important aspects of patient care, they may not directly address the immediate needs of a patient who is showing signs of severe distress and potential hypoxia. Starting CPR is not indicated unless the patient is unresponsive and has
