A nurse at a summer camp is assessing a camp counselor who has just been stung by a bee. The client says "I've had a bad reaction to bee stings before." Which findings should the nurse expect if the client develops anaphylaxis? Select all that apply

A. Urticaria, commonly known as hives, results from the systemic release of histamine and other inflammatory mediators from mast cells and basophils. These mediators increase capillary permeability and cause localized vasodilation, leading to the characteristic raised, pruritic wheals on the skin. In anaphylaxis, this integumentary response is often one of the earliest and most visible indicators of a generalized type 1 hypersensitivity reaction. B. Tachypnea occurs as a compensatory mechanism for respiratory distress caused by bronchospasm and laryngeal edema during an anaphylactic event. As the airway narrows due to inflammatory swelling, the body increases the respiratory rate to maintain adequate gas exchange and cellular oxygenation. The nurse must recognize an increased breathing frequency as a critical sign that the client's pulmonary function is being compromised by the systemic allergic response. C. Hypertension is not an expected finding in anaphylaxis; instead, the nurse would expect to see profound hypotension. Massive systemic vasodilation and increased capillary permeability lead to a relative and absolute fluid volume deficit within the intravascular space. This drop in systemic vascular resistance results in distributive shock, which is a life-threatening component of anaphylaxis that requires immediate intervention with epinephrine to restore blood pressure. D. Abdominal cramping is a recognized gastrointestinal manifestation of anaphylaxis caused by the contraction of smooth muscles in the digestive tract. Histamine release triggers increased peristalsis and mucosal edema, which can lead to nausea, vomiting, or acute cramping pain. While often overshadowed by respiratory or cardiovascular symptoms, these gastrointestinal findings are important diagnostic criteria for a multi-systemic anaphylactic reaction following an allergen exposure. E. Bradycardia is atypical in the early stages of anaphylaxis, where the heart rate usually increases significantly as a compensatory response to falling blood pressure. Tachycardia occurs as the heart attempts to maintain cardiac output in the face of widespread vasodilation and reduced venous return. A slow heart rate is generally only seen in the terminal stages of cardiovascular collapse or if the client is taking specific medications like beta-blockers. F. Angioedema involves deep dermal and subcutaneous swelling, particularly around the face, lips, tongue, and throat, due to massive fluid leakage from the vasculature. This finding is highly concerning in anaphylaxis because it can lead to total upper airway obstruction and asphyxiation within minutes. The nurse must prioritize the assessment of the oral cavity and neck to ensure the airway remains patent during the progression of the allergic reaction.
