What are common signs of anaphylaxis in a recovering patient?

The signs of anaphylaxis are critical to identify promptly because this severe allergic reaction can be life-threatening. The correct choice highlights rapid swelling, difficulty breathing, hives, and hypotension as common manifestations of anaphylaxis.

Rapid swelling, often referred to as angioedema, can occur particularly around the face, throat, and tongue, leading to acute airway obstruction. Difficulty breathing is a hallmark sign of anaphylaxis due to bronchoconstriction and laryngeal edema, which can significantly compromise the patient’s ability to breathe effectively. Hives, or urticaria, are often present as a skin manifestation of an allergic reaction, indicating systemic involvement. Hypotension, or a significant drop in blood pressure, can occur due to vasodilation and increased vascular permeability, which can lead to shock and requires immediate intervention.

The other options include symptoms that may be associated with various medical conditions but do not specifically represent the typical signs of anaphylaxis. Recognizing and understanding these signs is essential for timely treatment, such as administering epinephrine, which can rapidly reverse the symptoms of anaphylaxis.
