Which of the following conditions is characterized by joint pain?

The condition characterized by joint pain is arthralgia. This term specifically refers to pain that occurs in one or more joints, and it can arise from a variety of causes, including injury, inflammation, or underlying systemic conditions such as arthritis. Understanding arthralgia is essential for recognizing the symptoms associated with various musculoskeletal disorders and ensuring appropriate diagnostic and treatment pathways.

In contrast, cardiomegaly refers to an enlargement of the heart, typically associated with various heart conditions, and does not involve joint pain. Atelectasis is the partial or complete collapse of a lung, resulting in respiratory issues, while bruit describes an abnormal sound heard during auscultation of blood vessels and is not related to joint pain. Each of these conditions has different implications and clinical assessments, highlighting the specificity of joint-related symptoms in arthralgia.
