A client is receiving oral vancomycin for a first episode of severe Clostridioides difficile infection. Review the trended data and answer the questions.

Quick answer
The client has fulminant C. difficile colitis with hemodynamic instability, rising lactate, and abdominal rigidity, indicating possible toxic megacolon or perforation. Immediate provider notification and escalation to surgical evaluation is the priority.

Why this is correct
Worsening vital signs, rising WBC and creatinine, and progression from distention to rigidity are red flags for fulminant colitis. Delaying escalation risks perforation, sepsis, and death.

Clinical picture
Fulminant C. difficile infection is defined by hypotension, shock, ileus, or megacolon. Abdominal rigidity and absent bowel sounds suggest impending perforation. Surgical consultation is indicated for severe complicated disease.

Memory hook
Remember the '3 Ds' of severe C. diff: Distention, Deteriorating vitals, and Drowsiness. Escalate immediately when these appear.

NCLEX decision rule
In severe C. difficile infection, lack of improvement after 3 days of appropriate therapy or any sign of hemodynamic instability or peritonitis warrants urgent provider notification and consideration of surgical evaluation.

Why the alternatives are wrong
Continuing current therapy and reassessing in 4 hours is unsafe because the client is deteriorating rapidly. Requesting an infectious disease consult without immediate provider notification delays critical intervention. Administering an antipyretic and encouraging oral fluids is insufficient for hypotension and possible perforation.
