, Pathophysiology Exam 2026-2027: 102 MCQs with Answers
Section A: Immunology and Infection (Questions 1-5)
Question 1
Describe how the body responds to an infection involving T cells and B cells.
A) T cells directly engulf pathogens while B cells promote inflammation
B) T cells produce cytokines, which stimulate B cells to produce antibodies
C) B cells activate T cells to release histamine and chemokines
D) T cells and B cells both produce antigens to neutralize toxins
Answer: B
Explanation: In the adaptive immune response, helper T cells recognize antigens presented
by antigen-presenting cells and release cytokines. These signaling molecules activate B cells,
which differentiate into plasma cells that secrete specific antibodies targeting the pathogen.
Question 2
A patient presents with high fever, severe headache, and stiff neck during summer months.
Which infection is most likely?
A) Lyme disease
B) West Nile Virus
C) Erythema infectiosum
D) Gonorrhea
Answer: B
Explanation: West Nile Virus is transmitted through infected mosquito bites and typically
presents with severe neurological symptoms including high fever, headache, and nuchal
rigidity (stiff neck). It is more common during mosquito season in summer and early fall.
Question 3
Which microorganism causes Lyme disease and how is it transmitted?
A) Virus transmitted by mosquito bite
B) Bacterium transmitted by tick bite
C) Fungus transmitted by contaminated soil
D) Parasite transmitted by flea bite
Answer: B
Explanation: Lyme disease is caused by the spirochete bacterium Borrelia burgdorferi,
,transmitted to humans through the bite of infected Ixodes ticks. Early manifestations may
include erythema migrans rash, fever, and fatigue.
Question 4
A child presents with mild fever, upper respiratory symptoms, and suddenly develops bright
red cheeks resembling a slap mark. This presentation is characteristic of:
A) Measles
B) Scarlet fever
C) Fifth disease (erythema infectiosum)
D) Roseola
Answer: C
Explanation: Erythema infectiosum, commonly known as fifth disease, is caused by
parvovirus B19. The classic presentation includes a febrile upper respiratory illness followed
by the characteristic "slapped cheek" facial rash, which typically appears after the initial
symptoms resolve.
Question 5
Which statement correctly differentiates innate immunity from adaptive immunity?
A) Innate immunity targets specific pathogens while adaptive immunity is general and non-
specific
B) Innate immunity is the first line of defense and is non-specific; adaptive immunity
develops after exposure and is specific
C) Both innate and adaptive immunity require prior exposure to pathogens
D) Innate immunity involves antibody production while adaptive immunity involves physical
barriers
Answer: B
Explanation: Innate immunity provides immediate, non-specific defense mechanisms
including physical barriers, phagocytic cells, and inflammatory responses. Adaptive
immunity develops over time following exposure to specific antigens, involving memory
cells and targeted responses through B and T lymphocytes.
, Section B: Genetics and Congenital Disorders (Questions 6-10)
Question 6
Which statement best explains how DNA changes lead to congenital abnormalities?
A) DNA changes only affect physical appearance and not organ development
B) Mutations in genes or chromosomal abnormalities disrupt normal embryonic development
C) Congenital abnormalities result exclusively from environmental factors during pregnancy
D) DNA changes are repaired before birth and rarely cause abnormalities
Answer: B
Explanation: Congenital abnormalities arise from alterations in DNA, including gene
mutations (such as single nucleotide changes) or chromosomal abnormalities (such as
aneuploidy or structural rearrangements). These genetic alterations disrupt normal
developmental processes during embryogenesis.
Question 7
Obesity and diabetes in a pregnant individual are risk factors for having a child with which
condition?
A) Cystic fibrosis
B) Huntington's disease
C) Spina bifida
D) Hemophilia
Answer: C
Explanation: Maternal obesity and pre-gestational diabetes are established risk factors for
neural tube defects, including spina bifida. Hyperglycemia during early pregnancy interferes
with normal neural tube closure, which occurs around weeks 3-4 of gestation.
Question 8
Why is hemophilia more common in males?
A) The gene mutation is located on the Y chromosome
B) Males have only one X chromosome, so a single recessive mutation on the X chromosome
causes the disorder
C) Females are immune to bleeding disorders
D) The disorder is caused by environmental factors that affect males exclusively
Answer: B
Explanation: Hemophilia A and B are X-linked recessive disorders. Males inherit only one
