Choose the most likely options for the information missing from the statement(s) by selecting from the lists of options provided. The nurse recognizes that the client has ____ evidenced by ____. (Finding)

• Appendicitis: The sudden onset of right lower quadrant pain, elevated WBC count, low-grade fever, and CT scan findings of a dilated appendix and fat stranding point to acute appendicitis. This is a common surgical emergency that requires prompt diagnosis and intervention. • Computed tomography (CT) scan results: The CT scan is the most definitive diagnostic tool for appendicitis. A 7 mm dilated appendix with fat stranding is classic radiologic evidence of appendiceal inflammation and supports surgical consultation. • White blood cell count: The client’s WBC is 16,000/mm³, which is elevated and indicative of a systemic inflammatory response, commonly seen in appendicitis. Leukocytosis helps confirm infection and supports imaging findings. Rationale for Incorrect Options: • Gastroenteritis: Typically presents with diffuse abdominal cramping, diarrhea, and vomiting, often related to foodborne illness or viral infection. The absence of diarrhea and the presence of localized RLQ pain make this diagnosis unlikely. • Peptic Ulcer Disease: Presents with epigastric pain, often related to meals or NSAID use. Pain is typically described as burning or gnawing, and not associated with right lower quadrant tenderness or leukocytosis, which are more consistent with appendicitis. • Red blood cells count: The RBC count is within normal limits and does not aid in diagnosing appendicitis. It may be more relevant in cases of anemia, bleeding, or systemic illness but is not diagnostic in this scenario. • Temperature: 100.8° F (38.2° C): A low-grade fever supports the presence of inflammation or infection. While nonspecific, it adds clinical weight to the suspicion of appendicitis when correlated with WBC elevation and CT results.
