Chicago Emergency Medical Technician (EMT) Practice Exam

Visceral pain is the correct answer because it specifically refers to pain that originates from internal organs, such as those found in the abdominal cavity. This type of pain is often described as a deep, squeezing, or dull sensation and is typically poorly localized, which means that it can be difficult for patients to identify its exact location. Visceral pain is usually a result of the stretching, inflammation, or ischemia of the organs.

In contrast, rebound pain indicates pain that occurs upon the release of pressure from the abdomen and is primarily associated with peritonitis or appendicitis. Somatic pain arises from the skin, muscles, and bones, and is well-localized, making it easier for patients to pinpoint the pain. Parietal pain, also localized, originates from irritation of the peritoneum, the lining of the abdominal cavity, and generally has a sharp or stabbing quality distinct from the diffuse nature of visceral pain.
