The nurse is assessing a female patient who reports severe abdominal pain in the right lower quadrant (RLQ). Which condition should the nurse suspect? Select all that apply.

A. Peptic ulcer: Pain from a gastric or duodenal ulcer is typically localized in the epigastric region or the upper quadrants. It is often described as a burning or gnawing sensation related to food intake or fasting. It is anatomically distant from the right lower quadrant of the abdomen. B. Appendicitis: The vermiform appendix is located in the cecum within the right lower quadrant of the abdominal cavity. Inflammation of this organ typically causes localized pain at McBurney's point along with rebound tenderness. It is the most common surgical emergency presenting with acute pain in this specific quadrant. C. Hemorrhoids: These are swollen veins in the lower rectum and anus that cause localized discomfort, itching, or bleeding during defecation. They do not produce generalized or localized abdominal pain in the right lower quadrant. They are an anorectal vascular issue rather than an intra-abdominal inflammatory process. D. Cholecystitis: Inflammation of the gallbladder typically manifests as severe pain in the right upper quadrant (RUQ). This pain may radiate to the right scapula or shoulder following the ingestion of fatty meals. It is not a standard finding in the lower regions of the abdominal cavity. E. Tubal (ectopic) pregnancy: A fertilized ovum implanted in the right fallopian tube can cause sudden, severe pain in the right lower quadrant as the tube distends. This is a life-threatening emergency that must be ruled out in any female of childbearing age with lower abdominal pain. It requires immediate surgical or medical intervention.
