Bites and Stings

A nurse is assessing a client who was stung by a bee 30 minutes ago. Which assessment finding would be the priority concern indicating a systemic allergic reaction?

1 Stridor and difficulty breathing ✓ 정답
2 Localized swelling at the sting site
3 Mild itching around the wound
4 Pain and redness at the sting site

해설

Stridor and difficulty breathing indicate laryngeal edema and bronchospasm, which are life-threatening manifestations of anaphylaxis requiring immediate intervention. Localized swelling, itching, pain, and redness are non-life-threatening local reactions manageable with supportive care.

Understanding the Priority: Systemic vs. Local Reaction
When a client presents after a bee sting, the nurse must rapidly differentiate between a localized inflammatory response and a systemic hypersensitivity reaction. A localized reaction involves symptoms confined to the sting area, such as pain, redness, and swelling, which are mediated by histamine release directly at the site. In contrast, a systemic reaction, or anaphylaxis, is a severe, rapidly developing hypersensitivity response that can be life-threatening if not promptly identified and treated ^[1]. The priority in assessment is always to identify threats to the airway, breathing, and circulation (ABCs).

Analysis of Assessment Findings
The finding of stridor and difficulty breathing is the priority concern. Stridor is a high-pitched, harsh sound heard during inspiration, indicating significant narrowing or obstruction of the upper airway, specifically the larynx or trachea. In the context of anaphylaxis, this is caused by angioedema, where massive fluid shifts and swelling occur in the deep dermis and submucosal tissues ^[3]. This airway compromise directly threatens ventilation and oxygenation, representing an immediate risk of respiratory failure and death.

The other options describe findings consistent with a local allergic reaction:
- Localized swelling at the sting site is an expected local effect of histamine and other inflammatory mediators released from mast cells at the site of envenomation.
- Mild itching around the wound is a common localized symptom caused by histamine stimulating nerve endings.
- Pain and redness at the sting site are classic signs of localized inflammation, resulting from vasodilation and the activation of pain receptors.

These localized symptoms, while uncomfortable, do not indicate a systemic reaction and are not the nurse's immediate priority when a systemic, life-threatening condition is suspected.

Pathophysiology and Clinical Decision-Making
Anaphylaxis is a systemic hypersensitivity reaction that can be triggered by insect stings, particularly from hymenopteran insects like bees ^[2]. The reaction occurs when the allergen cross-links immunoglobulin E (IgE) on mast cells and basophils, triggering a massive release of mediators such as histamine, tryptase, and leukotrienes. This leads to a cascade of systemic effects: increased vascular permeability (causing edema and hypotension), smooth muscle contraction (causing bronchospasm), and vasodilation. The presence of respiratory symptoms like stridor, wheezing, or dyspnea signals that the reaction has progressed beyond a local issue and is now a systemic, multi-organ crisis. The nurse’s immediate clinical judgment must focus on securing the airway and preparing to administer intramuscular epinephrine, the first-line treatment for anaphylaxis, as delays can lead to poor outcomes, including cardio-respiratory failure ^[2]^[3].
