A community health nurse is preparing a public service announcement about Lyme disease. Which of the following strategies should the nurse include as an example of secondary prevention?

Secondary prevention focuses on early detection of disease in order to limit its progression and reduce harm. Notifying your health care provider if you notice a rash is the correct answer because recognizing a potential symptom of Lyme disease — the characteristic bull's-eye rash — and seeking prompt medical evaluation represents screening and early diagnosis, which are the hallmarks of secondary prevention. Early treatment can prevent the disease from advancing to more serious stages. Checking clothing and body for ticks after being outdoors and wearing long-sleeved shirts and pants while outdoors are both examples of primary prevention, which aims to prevent disease from occurring in the first place by reducing exposure to the causative agent. Similarly, using EPA-registered insect repellants is a primary prevention strategy because it targets reducing tick bites before infection can occur. Tertiary prevention would involve managing complications or rehabilitation after Lyme disease has already been established, which none of the options describe. Students often confuse primary and secondary prevention; the key distinction is that primary prevention acts before any exposure or disease onset, while secondary prevention acts after exposure or at the earliest sign of disease to detect and treat it quickly.
