Certified Emergency Nurse (CEN) Practice Test

Janeway lesions are characterized as non-tender erythematous lesions commonly found on the palms and soles. These lesions are typically associated with infective endocarditis and occur due to embolization of infected material, leading to localized blood flow disturbances. The non-tender nature of these lesions is significant, as it helps distinguish them from other cutaneous findings related to infection or inflammation, which are often painful or tender. Their appearance, typically as small reddish lesions, differentiates them from other lesions like nodules or ulcers that may be associated with other conditions. Recognizing Janeway lesions and their characteristics is crucial for emergency nurses, as they can indicate underlying systemic issues that may require immediate intervention.
