B、 Rebound tenderness, McBurney’s sign, low-grade fever.
C、 Right lower quadrant pain, Chvostek’s sign, muscle guarding.
D、 Periumbilical pain, Trousseau’s sign, pain relief with pressure.

【正确答案】 B

【答案解析】Rebound tenderness, McBurney’s sign (pain midway between umbilicus and right iliac crest), and a low-grade fever are all signs of appendicitis. Other clinical findings include a rigid abdomen, a preference to lie still with right leg flexed, right lower quadrant pain, muscle guarding, periumbilical pain, anorexia, nausea, and vomiting. The other findings aren’t signs of appendicitis.
