An entomologist on a swamp survey develops a bullseye (target) rash around a tick bite site three days after the bite. This presentation is MOST consistent with:
Answer: Lyme disease (erythema migrans)
Erythema migrans, the expanding bullseye-pattern rash, is the hallmark early sign of Lyme disease caused by Borrelia burgdorferi transmitted by Ixodes ticks.
When removing an embedded tick from a person, the CORRECT technique is to:
Answer: Grasp the tick close to the skin with fine-tipped tweezers and pull upward with steady pressure
The CDC recommends using fine-tipped tweezers to grasp the tick as close to the skin as possible and pulling upward with steady, even pressure to avoid leaving mouthparts in the skin.
A pest management professional presents with nausea, headache, and weakness after applying an organochlorine product in an enclosed space. The MOST appropriate antidote class for severe organochlorine poisoning is:
Answer: Benzodiazepines for seizure control
Organochlorines cause CNS stimulation and seizures; benzodiazepines are the treatment of choice for seizure management, unlike organophosphates which require atropine and pralidoxime.
Which of the following is the MOST critical personal protective equipment item when applying fumigants such as methyl bromide or sulfuryl fluoride?
Answer: Self-contained breathing apparatus (SCBA)
Fumigants at lethal concentrations cannot be detected by smell at safe levels, requiring SCBA to provide a completely independent air supply for applicators.
A person reports being stung by a Africanized honey bee swarm and received over 500 stings. Even without allergy, this victim is at serious risk for:
Answer: Systemic toxic envenomation causing renal failure, rhabdomyolysis, or cardiac arrhythmia
Mass envenomation with hundreds of bee stings delivers enough melittin to cause systemic toxicity including hemolysis, rhabdomyolysis, acute kidney injury, and cardiac dysrhythmias.
During a pest inspection, a technician is splashed with a liquid pyrethroid concentrate on bare skin. After removing contaminated clothing, the skin should be washed with:
Answer: Soap and large amounts of cool water for at least 15 minutes
Washing with soap and copious water for at least 15 minutes removes the pyrethroid from the skin without causing additional irritation from harsh chemicals.
Which of the following bee or wasp venom components is the PRIMARY cause of anaphylaxis in sensitized individuals?
Answer: Phospholipase A2 (PLA2)
Phospholipase A2 is the major allergen in honey bee venom responsible for IgE-mediated anaphylaxis in sensitized individuals.
