Model Answers for FRCPath Part 2 Case-Based Questions with FRCPath Prep Feedback

The FRCPath Part 2 Medical Microbiology exam challenges candidates with real-life case scenarios to assess their diagnostic reasoning, laboratory interpretation, and clinical decision-making. One of the best ways to prepare is to study model answers aligned with examiner expectations.

In this post, we break down key case-based questions, present model answers, and provide actionable feedback—just like you’d receive in the real exam or a consultant-led viva.

🧪 Sample Case-Based Question 1:

Case: A 34-year-old renal transplant patient presents with fever, fatigue, and increasing creatinine levels. Blood cultures are positive for Candida albicans.

Model Answer (Condensed):

• Diagnosis: Fungaemia (Candidaemia) in immunocompromised host

• Likely source: CVC, GI translocation

• Further investigations:

  • β-D-glucan assay

  • Fundoscopy (rule out endophthalmitis)

  • Echocardiography

• Management:

  • Remove CVC

  • Start IV echinocandin (e.g., caspofungin)

  • Step down to oral azole after 2 weeks of clearance

• Infection control: Source isolation not needed; hand hygiene critical

FRCPath Prep Feedback: Excellent identification of the likely source and appropriate investigations. You should also mention the duration of therapy and criteria for transition to oral treatment. Do not forget to discuss antifungal resistance trends in Candida spp.

🦠 Sample Case-Based Question 2:

Case: You receive a sample from a 65-year-old ICU patient with ventilator-associated pneumonia. Culture grows Acinetobacter baumannii resistant to all beta-lactams including carbapenems.

Model Answer (Condensed):

• Diagnosis: XDR Acinetobacter VAP

• Resistance mechanism: OXA-type carbapenemase

• AST options: Colistin, tigecycline, cefiderocol (if available)

• Treatment approach:

  • Discuss with ID/micro consultant

  • Consider combination therapy if monotherapy fails

• Infection control: Enhanced contact precautions, environment decontamination

• Public health: Notify IPC team and monitor for transmission

Feedback:

Well-structured. To gain higher marks, justify your antimicrobial choices using EUCAST breakpoints and describe local resistance patterns if asked. Always explain your rationale for IPC escalation.
