A nurse is caring for a 28-year-old patient with severe asthma who presents to the emergency department with acute respiratory distress. Which action should the nurse take first to ensure patient safety?

Assessing respiratory status and oxygen saturation is the first priority to determine severity and guide immediate interventions. Other actions like positioning, bronchodilator administration, or ABG sampling should follow assessment.

Clinical Reasoning and Priority Setting in Acute Respiratory Distress

When a patient with severe asthma presents with acute respiratory distress, the initial moments of care are critical. The fundamental principle guiding the nurse's first action is the nursing process: assessment must always precede intervention. Before any treatment is administered, the nurse must establish a baseline of the patient's current physiological status to ensure the chosen intervention is appropriate and to later evaluate its effectiveness. This is not merely a procedural step but a critical safety mechanism.

The 2026 formalized expert recommendations from the French Society of Emergency Medicine and the French Intensive Care Society provide a structured framework for this initial assessment. The guidelines emphasize that the very first step in managing a patient with respiratory distress is a rapid, systematic clinical evaluation to determine the severity and immediate threats to life ^[1]. This evaluation directly informs all subsequent therapeutic decisions. Administering a bronchodilator (option 1) or positioning the patient (option 2) are high-priority interventions, but performing them without first understanding the patient's degree of hypoxemia, work of breathing, and overall stability could delay the recognition of a deteriorating condition or lead to an incomplete picture for the medical team. Similarly, while obtaining an arterial blood gas (option 3) is a valuable diagnostic tool, it is an invasive procedure that provides data after a processing delay; it does not replace the immediate, non-invasive, and continuous information gained from a direct respiratory assessment and pulse oximetry.

The recommended initial assessment involves a "look, listen, and feel" approach integrated with objective data. The nurse must immediately evaluate the patient's level of consciousness, ability to speak, use of accessory muscles, respiratory rate, pattern, and breath sounds, while simultaneously obtaining a pulse oximetry reading ^[1]. A saturation below 90% on room air signifies critical hypoxemia and necessitates immediate, aggressive intervention. This rapid assessment allows the nurse to prioritize actions based on objective findings. For example, a silent chest on auscultation, indicating severely diminished airflow, is a more ominous sign than loud wheezing and would signal an impending respiratory arrest, changing the urgency and type of intervention needed. Therefore, the act of assessing respiratory status and oxygen saturation is the foundational safety action that directly guides and validates every subsequent step, from bronchodilator therapy to escalation of care ^[1].
