The nurse is assessing a client's abdomen. For which reason should the nurse perform deep palpation?

Abdominal assessment is a structured clinical examination used to evaluate underlying visceral structures, peritoneal integrity, and abdominal wall characteristics. Deep palpation is a technique that applies sustained pressure to assess deeper anatomical structures such as solid organs and detect masses. It allows clinical differentiation between superficial abdominal wall findings and deeper intra-abdominal pathology. Rationale: A. Deep palpation is performed to identify abdominal organs such as the liver, spleen, kidneys, and detect deep masses. It allows the examiner to assess size, shape, and position of underlying viscera that are not accessible through light palpation. This technique evaluates deeper anatomical structures within the peritoneal cavity. B. Abdominal tenderness is primarily assessed using light palpation, which evaluates superficial pain responses and guarding. Deep palpation may worsen discomfort but is not the primary method for detecting tenderness. Tenderness assessment focuses on patient response to gentle pressure rather than deep tissue evaluation. C. Muscular resistance, including voluntary or involuntary guarding, is best evaluated using light palpation. Deep palpation may obscure subtle muscle tension due to increased pressure. Light palpation allows clearer differentiation between voluntary guarding and involuntary rigidity associated with peritoneal irritation. D. Surface evaluation of the abdomen is conducted using inspection and light palpation, not deep palpation. Surface assessment focuses on skin integrity, contour, symmetry, and superficial abnormalities. Deep palpation is intended for deeper structural assessment rather than superficial examination findings.
