A client presents to the emergency department 30 minutes after being stung by a bee. The client reports localized pain, swelling, and redness at the sting site on the right forearm. Vital signs are stable, and there are no signs of systemic allergic reaction. What is the most appropriate initial nursing intervention?
1Apply a warm compress to the sting site to promote circulation
2Administer oral antihistamines immediately to prevent allergic reaction
3Remove the stinger by scraping it out with a credit card or similar flat object✓ 정답
4Cleanse the area with hydrogen peroxide to prevent secondary infection
해설
The priority is immediate stinger removal by scraping to prevent continued venom injection. Other interventions like cold compresses or antihistamines are secondary after stinger removal.
Core Nursing ExplanationKey Concept Analysis: This question tests the priority nursing action for a bee sting in a patient showing only a localized reaction. The core principle is preventing further harm. A honeybee's stinger is barbed and remains embedded in the skin, attached to a venom sac. This sac can continue to contract and inject venom for up to a minute after the sting. Therefore, the most urgent action is to stop this ongoing venom delivery.
Answer Rationale: Key Point! The correct initial intervention is to remove the stinger by scraping it out. The "scraping" method (using a credit card, driver's license, or fingernail) is crucial. It flattens the stinger and venom sac against the skin and pushes it out, minimizing the amount of venom squeezed into the patient. This action directly addresses the source of the problem and is the first step before any other care.
Distractor Analysis:
Watch out for confusion! Option ① suggests a warm compress. For a fresh insect sting with localized swelling and pain, cold application is indicated to reduce swelling, inflammation, and pain. Heat would increase blood flow and potentially worsen swelling and venom spread.
Option ② involves administering oral antihistamines immediately. While antihistamines (like diphenhydramine) are appropriate for managing allergic symptoms and itching, they are not the initial intervention. The patient is stable with no systemic signs. The priority is to stop the venom source first. Medication administration follows assessment and initial first aid.
Option ④ recommends cleansing with hydrogen peroxide. While cleansing the wound is important to prevent infection, it is not the immediate priority. Furthermore, hydrogen peroxide can damage healthy tissue and delay healing. A milder antiseptic like soap and water or povidone-iodine is preferred after stinger removal.
Related Concepts: This scenario highlights the difference between a localized reaction (pain, redness, swelling at the site) and a systemic anaphylactic reaction (involving airway, breathing, circulation - e.g., wheezing, stridor, hypotension, hives). Nursing priorities shift dramatically if systemic signs are present (then, ABCs and epinephrine become the priority).
Concept Summary
Concept
Key Takeaway
Bee Stinger Removal
Scrape, don't squeeze! Use a flat object to prevent injecting more venom.
Local vs. Systemic Reaction
Local: Manage site. Systemic (Anaphylaxis): ABCs, Epinephrine, call for help.
Administer IM Epinephrine, ensure airway, call rapid response.
Life-threatening reaction requires immediate vasoconstriction and bronchodilation.
General Minor Wound/Cut
Cleanse with soap and water or mild antiseptic.
Primary goal is to prevent infection by removing debris and bacteria.
Anatomy, Physiology & Pharmacology Points
Pathophysiology: Bee venom contains proteins (e.g., melittin) that cause local histamine release, leading to pain, redness, and swelling (local reaction). In susceptible individuals, it triggers a massive IgE-mediated systemic release of histamine and other mediators, causing anaphylaxis.
Pharmacology - Antihistamines (e.g., Diphenhydramine): H1-receptor antagonists. They compete with histamine for receptor sites, reducing allergic symptoms like itching, hives, and rhinorrhea. They do not reverse bronchospasm or hypotension in anaphylaxis—that requires epinephrine.
Pharmacology - Epinephrine (Adrenaline): The first-line drug for anaphylaxis. It causes vasoconstriction (raising BP), bronchodilation (easing breathing), and reduces angioedema through its alpha- and beta-adrenergic effects.
Memory Tips
Bee Sting Priority: Think "Scrape Before Anything" (SBA).
Anaphylaxis vs. Local Reaction: Local = "Here" (at the site). Systemic = "Everywhere" (whole body systems affected).
Compress Rule: For new injuries/swelling, remember "Cold Comes First." Use cold to constrict vessels and reduce inflammation.
High-Frequency NCLEX Topics
This is a classic NCLEX question testing prioritization and basic first aid. The NCLEX loves to present a stable patient with a clear, immediate problem (the embedded stinger) and distract you with other reasonable but secondary nursing actions (cleaning, medicating). Always ask: "What action will stop the harmful process right now?"
Watch Out for Question Variations!
Shift in Priority: The same scenario could add symptoms: "The client now develops wheezing and facial swelling." The correct answer immediately changes to administering epinephrine and calling for help.
Patient Education Focus: The question could ask: "What should the nurse teach a client with a bee sting allergy?" Correct answers would include: carrying an epinephrine auto-injector, wearing a medical alert bracelet, and avoiding known triggers.
Procedure Focus: It could test the method of removal: "The nurse plans to remove a bee stinger. Which technique is correct?" Correct answer: "Scrape the skin horizontally with a firm-edged object."
Nursing Clinical Practice GuideClinical Scenario: You are triaging a 42-year-old male in the ED. He is alert, holding his right forearm. He states, "A bee got me about half an hour ago in the garden." You observe a red, swollen area about 3 cm in diameter on the dorsal forearm, with a small black dot (the stinger) visible in the center. His vital signs are BP 128/78, HR 88, RR 16, SpO2 99% on room air. He denies any trouble breathing, throat tightness, dizziness, or hives elsewhere.
Nursing Intervention Strategy:
Assessment (ABCDE): Quickly but thoroughly assess Airway, Breathing, Circulation, Disability (neuro), and Exposure (for other stings or hives). Confirm stable vitals and absence of systemic symptoms.
Immediate Action: Don gloves. Use the edge of a patient ID band or a gauze pad folded into a firm edge. Firmly scrape across the skin over the stinger to flick it out. Do not use tweezers or pinch the stinger, as this compresses the venom sac.
Subsequent Care: After removal, wash the area gently with soap and water. Apply a cold pack or ice wrapped in a cloth for 15-20 minutes to reduce swelling and pain. Elevate the arm if possible.
Medication & Monitoring: Based on provider orders, you may administer an oral antihistamine (e.g., cetirizine) for itching and/or an analgesic (e.g., acetaminophen) for pain. Continue to monitor for at least 30-60 minutes for any delayed systemic reaction, especially since the sting occurred 30 minutes prior to arrival.
Patient Education: Instruct the client to watch for signs of infection (increased redness, warmth, pus, fever) or delayed allergic reaction. Recommend OTC antihistamines for persistent itching and cool compresses. If he develops any difficulty breathing, swelling of the lips/tongue, or feels faint, he should call 911 immediately.
Patient Safety and Precautions:
Anaphylaxis Vigilance: Even with an initially localized reaction, monitor closely. Reactions can be biphasic, with symptoms recurring hours after the initial event.
Contraindication: Do not give antihistamines if the patient has significant prostate enlargement or glaucoma without consulting the provider, due to anticholinergic side effects.
Documentation: Document the time of the sting, assessment findings (including absence of systemic symptoms), method of stinger removal, interventions performed, patient response, and education provided.
Nursing Procedure & Medication FlowStinger Removal Procedure:
1. Explain the procedure to the client.
2. Perform hand hygiene and don non-sterile gloves.
3. Identify the stinger (black, small, embedded).
4. Place a flat, rigid edge (e.g., credit card, ID card, knife blade) against the skin at one side of the stinger.
5. Apply firm, sweeping pressure to scrape the stinger out in one motion.
6. Dispose of the stinger and gloves appropriately.
7. Cleanse the area.
Medication Administration (if ordered):
- Oral Antihistamine (e.g., Diphenhydramine 25-50 mg): Administer with water. Warn about potential drowsiness and advise against driving or operating machinery. Monitor for dry mouth, blurred vision, urinary retention.
- Epinephrine (for anaphylaxis - 0.3 mg IM in anterolateral thigh): This is an emergency drug. Administer immediately for signs of systemic reaction. Massage the site after injection to enhance absorption. Be prepared for repeat dosing in 5-15 minutes if no improvement. Monitor for tachycardia, hypertension, and anxiety as side effects.
A Word from Your Senior Nurse
"In the ED, we see a lot of bee stings. It's easy to jump to cleaning the wound or giving a pill, but always pause and ask: 'Is the stinger still in?' That little black dot is the source of the problem. Taking 10 seconds to scrape it out properly can significantly reduce the client's discomfort and potential for a worse reaction. This is a perfect example of a simple, independent nursing action that has a direct and immediate impact on patient outcomes. On the NCLEX and in real life, your ability to identify and act on that one key detail is what makes you an effective nurse."
