The nurse is assessing a client with suspected appendicitis. Which finding is most indicative of this condition?

Choice A reason: An IgE-mediated (Type I) hypersensitivity reaction, like anaphylaxis, occurs post-bee sting, with rapid onset of rash, shortness of breath, hypotension, and tachycardia. IgE antibodies trigger mast cell degranulation, releasing histamine, causing vasodilation, bronchoconstriction, and systemic symptoms, matching the client’s acute presentation.

Choice B reason: Cell-mediated (Type IV) hypersensitivity involves T-cells, causing delayed reactions like contact dermatitis, not rapid systemic symptoms. Bee sting reactions are immediate, driven by IgE, not T-cells. Rash, hypotension, and respiratory distress indicate anaphylaxis, not a delayed cell-mediated response.

Choice C reason: Autoimmune responses involve self-directed antibodies, as in lupus, not triggered by external allergens like bee stings. The client’s acute rash, hypotension, and respiratory distress suggest an IgE-mediated anaphylactic reaction, not an autoimmune process, which is unrelated to acute allergen exposure.

Choice D reason: Type II hypersensitivity involves antibody-mediated cytotoxicity, as in transfusion reactions, not allergen-induced systemic symptoms. Bee sting reactions are IgE-driven, causing immediate anaphylaxis with rash and hypotension, not cytotoxic damage, making Type II inappropriate for the client’s acute presentation.

Choice A reason: Chronic constipation and serum gastrin levels are not directly relevant to acute pancreatitis. Constipation may indicate gastrointestinal issues, but gastrin primarily relates to gastric acid secretion. These do not confirm pancreatitis or guide acute management, unlike amylase levels, which are diagnostic for pancreatic inflammation.

Choice B reason: Helicobacter pylori antibodies indicate gastric infection, unrelated to pancreatitis, which involves pancreatic inflammation. Urine output is a general vital sign but not specific to pancreatitis diagnosis. Amylase and symptom severity are more critical for confirming and managing acute pancreatitis, making this less valuable.

Choice C reason: Bowel sounds and abdominal pain degree provide general information but are nonspecific. Pain is expected in pancreatitis, and bowel sounds may vary. Serum amylase and nausea/vomiting severity are more diagnostic, directly reflecting pancreatic inflammation and its systemic effects, making them more critical to report.

Choice D reason: Serum amylase levels are a key diagnostic marker for acute pancreatitis, as pancreatic inflammation releases amylase into the blood. Severity of nausea and vomiting reflects disease impact and fluid loss, guiding treatment. These are the most valuable data for reporting, as they confirm diagnosis and inform management.
