Explanation
Four evidence-based decisions Test an unformed stool in a client with three or more new unexplained unformed stools in 24 hours after reviewing laxatives and alternative causes. Begin contact precautions while evaluation is pending. For an initial CDI episode, fidaxomicin is preferred when resources permit and oral vancomycin remains acceptable. When symptoms resolve, do not perform a repeat test of cure.
Step 1 — Test the right client and specimen New unexplained diarrhea establishes pretest probability. Review laxatives and other causes, then send only unformed stool through the facility's diagnostic-stewardship algorithm.
Step 2 — Isolate before confirmation CDC recommends isolation and contact precautions for suspected or confirmed CDI so transmission prevention does not wait for the laboratory result.
Step 3 — Apply the treatment hierarchy IDSA/SHEA conditionally prefers fidaxomicin for an initial episode because of sustained response; a standard oral vancomycin course remains an acceptable alternative when resources or access limit fidaxomicin.
Step 4 — Avoid test-of-cure error Repeat testing is not recommended after symptoms resolve because a client may remain colonized despite clinical recovery.
NCLEX rule Link symptoms, specimen quality, immediate isolation, resource-sensitive treatment, and clinical follow-up.
Scenario (Stage 2 — Analyze cues)The client has six new watery stools without recent laxative use after significant antibiotic exposure.
Clinical judgment targetDistinguish immediate precautions and appropriate testing from premature or unnecessary repeat testing.
Diagnostic stewardship — Testing only an appropriate symptomatic client with an unformed specimen and interpreting results within the clinical context.
Initial CDI therapy — Fidaxomicin is preferred when available for an initial episode; oral vancomycin remains an acceptable alternative.
Test of cure — Repeat C. difficile testing after symptom resolution, which is not recommended because persistent colonization can produce a positive result.
