What does the term pruritus refer to?

Pruritus specifically refers to the sensation of itching. It can be caused by various factors, including skin conditions, allergic reactions, or as a complication of underlying health issues like kidney disease. In the context of hemodialysis patients, for instance, pruritus is a common complaint due to the accumulation of waste products and other irritants that can affect the skin. Understanding this term is important in nursing and patient care, as it helps in assessing and managing patient comfort and symptom relief effectively. The other terms relate to different sensations or symptoms; for example, pain implies discomfort, dizziness refers to a sensation of unsteadiness, and swelling denotes an increase in size or volume of a body part, all of which are distinct from the sensation of itching that pruritus describes.
