A nurse is caring for four adult clients on a medical-surgical unit. Which client should the nurse assess first based on the ABCDE priority framework?

A. A client with a temperature of 38.3°C (101°F) and flu symptoms. Hyperthermia and viral symptoms represent a stable physiological state without immediate life-threatening compromise. While the client requires monitoring and antipyretics, they do not take precedence over airway or circulatory emergencies. This presentation falls under the Exposure or Disability assessment categories. B. A client who is groggy and has slurred speech after surgery. Slurred speech and lethargy indicate neurological changes or anesthesia effects, categorized under "Disability" in the ABCDE framework. While concerning for potential stroke or over-sedation, these signs are secondary to active airway obstruction. The nurse should assess this client only after securing life-sustaining functions. C. A client with swelling in the neck and audible wheezing. Neck swelling and wheezing indicate a critical Airway and Breathing emergency, such as anaphylaxis or laryngeal edema. This client is at highest risk for complete respiratory arrest due to upper airway occlusion. Immediate intervention is required to maintain patency and prevent hypoxic brain injury. D. A client with a color change and decreased pulses in one leg. Diminished pulses and pallor signify Circulation issues related to peripheral vascular perfusion. While this indicates potential limb-threatening ischemia, the ABCDE hierarchy mandates resolving airway and breathing threats first. Circulatory assessment of an extremity follows the stabilization of central respiratory function.
