A nurse is caring for a client who was stung by a bee on the back and shoulders. The client reports pain, redness, and blistering. Which nursing action should the nurse implement first?

The immediate priority after a honey bee sting is to remove the stinger as quickly as possible. The correct technique is to scrape it out using a dull edge, such as a credit card or fingernail, rather than pinching and pulling it out with tweezers or fingers.

The rationale is rooted in the unique anatomy of the honey bee's venom apparatus. The stinger is bifurcated and attached to a venom sac that contains a piston-like mechanism. When the stinger embeds in human skin, the venom sac remains attached and continues to pulsate, actively injecting venom for up to 60 seconds after the initial sting ^[1]. Pinching or squeezing the venom sac with forceps or fingers compresses the sac, which can forcefully expel additional venom into the wound, worsening the local tissue injury and increasing the total venom dose ^[1].

A scraping motion with a straight edge, such as a credit card, effectively dislodges the stinger without applying pressure to the venom sac. This minimizes the volume of venom injected. The speed of removal is the most critical factor; even a delay of a few seconds can result in a significantly greater venom load. Therefore, removing the stinger by scraping is the first and most time-sensitive nursing action to limit the extent of the envenomation ^[1].

Other interventions, such as applying a cold compress for pain and swelling, administering an oral antihistamine for pruritus, or applying a topical corticosteroid for inflammation, are appropriate secondary measures. However, they do not address the ongoing mechanical injection of venom, which is the primary driver of the client's escalating pain, redness, and blistering. A warm compress is contraindicated as it would promote vasodilation and potentially enhance venom absorption.
