A 32-year-old client comes to the clinic with complaints of fatigue, muscle aches, and a rash on the thigh. The nurse observes a circular, red lesion with central clearing, resembling a bull's-eye. The client mentions having recently been on a camping trip in a wooded area. What is the most appropriate initial nursing action?

Rationale: A. Administer a dose of doxycycline as prescribed by the healthcare provider is correct because the client presents with classic signs of early Lyme disease, including fatigue, muscle aches, and the characteristic erythema migrans rash (bull’s-eye lesion), following a recent exposure in a wooded area where ticks are prevalent. Early antibiotic therapy, typically doxycycline for adults, is the first-line treatment and is crucial to prevent disease progression to more severe stages that can involve joints, the nervous system, or the heart. The nurse’s role is to promptly administer the prescribed antibiotic while monitoring for adverse effects. B. Assess the client for signs of neurological involvement, such as facial palsy is important in later stages of Lyme disease (disseminated infection), but it is not the first priority in a client with early localized disease. Early recognition and treatment prevent progression to these complications. C. Initiate a discussion about safe hiking practices to prevent tick bites is a valuable preventive intervention but does not address the client’s immediate health concern. Education on prevention can be provided after starting treatment. D. Schedule the client for serological testing for Lyme disease is not the most appropriate initial action because serological tests may be negative in the early stages of infection. Diagnosis of early Lyme disease is primarily clinical, based on the appearance of the characteristic rash and exposure history. Waiting for lab confirmation can delay necessary treatment.
