FCPS Part 1 Pathology MCQs: High-Yield Practice Questions & Prep

A sample of FCPS Part 1 Pathology MCQs across anatomy, physiology, haematopathology and microbiology — the subjects that carry the most weight in the paper — each with the reasoning behind the answer.

FCPS Part 1 Pathology draws heavily on anatomy, physiology, haematology and microbiology — more basic sciences than most candidates expect from a "Pathology" paper. Here is a short set of practice MCQs across the subjects that carry the most weight, each with the reasoning that makes the answer stick. The full bank has 3,800+ questions with an explanation on every one.

Anatomy & Histology

1. At the cervical transformation zone, stratified squamous epithelium meets columnar epithelium. This junction is clinically important because it is:

A) The site where ectopic pregnancies most often implant
B) The most common site of origin for cervical dysplasia and carcinoma ✅
C) Resistant to HPV infection due to keratinisation
D) Absent before puberty

Metaplastic squamous cells at this junction are the ones most vulnerable to persistent high-risk HPV infection, which is why cervical screening samples are taken from exactly this zone.

2. Which cell type is chiefly responsible for laying down new collagen during wound healing and fibrosis?

A) Macrophage
B) Fibroblast ✅
C) Neutrophil
D) Endothelial cell

Fibroblasts migrate into the wound during the proliferative phase and synthesise type III collagen first, which is later remodelled into stronger type I collagen.

Physiology

3. A left shift of the oxygen-haemoglobin dissociation curve, increasing haemoglobin's affinity for oxygen, is caused by:

A) Increased 2,3-BPG
B) Decreased pH (acidosis)
C) Decreased temperature ✅
D) Increased temperature

Hypothermia, alkalosis and low 2,3-BPG all shift the curve left; remembering this one factor lets you derive the rest, since a right shift is simply the opposite of each.

4. Which hormone plays the dominant long-term role in blood pressure regulation through renal sodium and water retention?

A) Antidiuretic hormone (ADH)
B) Aldosterone ✅
C) Atrial natriuretic peptide
D) Cortisol

Aldosterone acts on the distal tubule and collecting duct to reabsorb sodium (and water with it), making the renin-angiotensin-aldosterone axis the main long-term blood pressure regulator.

Haematopathology

5. Auer rods on a peripheral blood or bone marrow smear are most characteristic of:

A) Chronic lymphocytic leukaemia
B) Acute myeloid leukaemia ✅
C) Hodgkin lymphoma
D) Multiple myeloma

Auer rods are needle-shaped azurophilic granule clumps; they are especially numerous and bundled in acute promyelocytic leukaemia (AML-M3).

6. The Philadelphia chromosome, t(9;22) producing the BCR-ABL fusion gene, is the hallmark of:

A) Acute lymphoblastic leukaemia
B) Chronic myeloid leukaemia ✅
C) Polycythaemia vera
D) Essential thrombocythaemia

BCR-ABL creates a constitutively active tyrosine kinase, which is why tyrosine kinase inhibitors like imatinib transformed CML treatment.

Microbiology & Parasitology

7. Gram-negative diplococci on CSF Gram stain, in a previously healthy young adult with fever and neck stiffness, most likely indicate infection with:

A) Streptococcus pneumoniae
B) Neisseria meningitidis ✅
C) Haemophilus influenzae
D) Listeria monocytogenes

N. meningitidis is the classic cause of bacterial meningitis in adolescents and young adults, often with a petechial or purpuric rash from the associated meningococcaemia.

8. The definitive way to diagnose malaria is by identifying the organism on:

A) Stool microscopy
B) Thick and thin peripheral blood smear ✅
C) Urine culture
D) Sputum Gram stain

The thick smear screens for parasites and the thin smear identifies the Plasmodium species and stage, which guides treatment choice.

How to Use MCQs Well

Do timed blocks of 40 to 50 questions, then spend at least as long reviewing explanations as you did answering. Pathology rewards pattern recognition — tying a buzzword (Auer rods, Reed-Sternberg cells, Psammoma bodies) to its one correct answer — so track your misses by subject, not just by overall score, and revisit the subjects where you are weakest before moving on.

Practise With Explanations

HighYield's FCPS Part 1 Pathology QBank has 3,800+ MCQs across anatomy and histology, physiology, haematopathology, microbiology and parasitology, biochemistry, neoplasia, pharmacology and every other subject in the paper. Every question has a written explanation, and subject analytics show which area needs another pass. Your first 20 questions are free, no card required.

Frequently Asked Questions

Is FCPS Part 1 Pathology mostly basic sciences or mostly histopathology?

Both, but basic sciences carry real weight: anatomy, physiology and pharmacology questions sit alongside histopathology, haematopathology and microbiology in the paper, so a prep plan that only revises Robbins will leave gaps.

Are these real CPSP questions?

No. Our questions are modelled on the topics, style and difficulty of past papers and recalls, and are not copies of CPSP papers.
