Rationale for correct choices • appendicitis: The client presents with classic signs of appendicitis, including sudden onset right lower quadrant abdominal pain, nausea, vomiting, and mild fever. Appendicitis is further suggested by the progression of pain, localized tenderness, and systemic response (tachycardia). The acute presentation aligns with appendicitis rather than gastroenteritis or ectopic pregnancy. • computed tomography (CT) scan results: The CT scan shows a dilated appendix measuring 7 mm with fat stranding, which confirms inflammation consistent with appendicitis. Imaging is the definitive diagnostic tool in this scenario, providing objective evidence of the affected appendix. This finding directly supports the clinical suspicion and guides surgical intervention. • white blood cell count (WBC): The client’s WBC is elevated at 16,000/mm³, indicating an inflammatory response typical in appendicitis. Leukocytosis is a common laboratory finding in acute bacterial infection and helps differentiate appendicitis from other abdominal conditions. The elevated WBC complements the CT findings and clinical symptoms in confirming the diagnosis. Rationale for incorrect choices • Gastroenteritis: Gastroenteritis typically presents with diffuse abdominal pain, diarrhea, vomiting, and sometimes mild fever. This client has localized right lower quadrant pain without diarrhea, making gastroenteritis unlikely. Laboratory and imaging findings do not support gastrointestinal infection. • Ectopic pregnancy: Ectopic pregnancy is considered in reproductive-age females with abdominal or pelvic pain, often associated with missed periods or positive pregnancy test. This client has a negative urine pregnancy test and no gynecologic symptoms. The clinical presentation and CT findings are not consistent with ectopic pregnancy. • Electrolyte imbalances: Although electrolyte imbalances can occur with vomiting, the client’s labs show sodium, potassium, chloride, and CO₂ within normal limits. No evidence of dehydration or significant electrolyte disturbance is present. This does not explain the acute right lower quadrant pain. • Temperature: 101° F (38.3° C) orally: While the mild fever supports a systemic inflammatory response, fever alone is not diagnostic of appendicitis. It is a supportive finding rather than definitive evidence. Fever must be interpreted alongside WBC and imaging findings. • Pain level: The client’s severe pain indicates acute pathology, but pain alone cannot confirm appendicitis, as it can occur in multiple abdominal conditions. Diagnostic confirmation relies on laboratory and imaging results in addition to clinical assessment.
