During a physical exam, what test are you performing if you press into a patient's abdomen about 2-3 inches while they lie on their back?

The correct answer relates to a technique known as deep palpation. This method involves pressing down into a patient's abdomen by about 2-3 inches to assess the underlying structures more thoroughly. Deep palpation allows a clinician to evaluate size, shape, tenderness, and any abnormalities in the organs, masses, or fluid within the abdominal cavity. It is particularly used to detect deeper issues that may not be apparent upon lighter examination.

Light palpation, on the other hand, would involve a gentler touch to assess surface characteristics and tenderness without penetrating deeply into the abdomen. Therefore, while light palpation is an important part of an abdominal exam, it does not encompass pressing down to the extent described in the question.

Blumberg's sign is a specific test for rebound tenderness that assesses for peritoneal irritation, not the palpation technique itself. Voluntary guarding refers to a patient's conscious tightening of abdominal muscles during palpation, which can occur due to discomfort or anxiety, rather than a technique employed by the clinician.

In summary, the given scenario clearly describes a deep palpation technique since it involves applying significant pressure to evaluate the deeper abdominal organs and structures.
