When assessing for appendicitis, what signs might the nurse look for? (Select all that apply.)

A. Rovsing sign: This sign is positive when palpation of the left lower quadrant causes pain in the right lower quadrant, indicating possible appendicitis. B. Psoas sign: This sign is positive when pain occurs upon extending the right thigh or flexing the hip against resistance, suggesting irritation of the psoas muscle due to appendicitis. C. Murphy sign: This sign is associated with gallbladder inflammation (cholecystitis), not appendicitis. D. Obturator sign: This sign is positive when pain occurs upon flexing and internally rotating the right thigh, which can indicate irritation of the obturator muscle due to appendicitis.
