A nurse is assisting with the care of a client in the emergency department who presents with abdominal pain, bloating, nausea, and rebound tenderness. Which of the following potential provider prescriptions should the nurse anticipate or identify as contraindicated for the client?

This scenario involves an emergency department client presenting with clinical signs of acute peritonitis or appendicitis. Knowledge of gastrointestinal pathophysiology, perforation risks, and emergency pre-operative management must be applied to identify harmful clinical interventions. Choice A rationale Intravenous access is essential for fluid resuscitation and medication administration in acute abdominal conditions. It maintains vascular volume, addresses dehydration from nausea, and provides a route for rapid therapeutic interventions. Choice B rationale Intravenous hydromorphone provides necessary analgesia for severe abdominal pain. Relieving acute pain lowers sympathetic nervous system stimulation, stabilizes vital signs, and improves client cooperation during physical examinations without masking localized peritoneal signs. Choice C rationale Administering 0.9 percent sodium chloride intravenously maintains intravascular volume and corrects electrolyte imbalances. This preserves renal perfusion and addresses fluid shifts into the peritoneal space caused by localized inflammatory responses. Choice D rationale Intravenous piperacillin/tazobactam provides broad-spectrum antimicrobial coverage targeting enteric pathogens. Early antibiotic administration is crucial to treat or prevent intra-abdominal sepsis resulting from suspected bacterial translocation or localized organ perforation. Choice E rationale Cleansing enemas increase intraluminal pressure within the colon and stimulate peristalsis. In a client with rebound tenderness indicating peritoneal inflammation, this increased pressure can cause perforation of an inflamed appendix or diverticulum. Choice F rationale Maintaining a diet as tolerated is contraindicated because the client exhibits signs of an acute abdomen requiring potential surgical intervention. The client must be strictly nothing by mouth to prevent aspiration during anesthesia.
