TOPIC 1: INFECTIOUS DISEASES
9 Questions • 9.0% of Exam • Explores various communicable and infectious diseases, their causes, and effects on the body.
QUESTION 1
Communicable disease
Answer: A disease that can be spread from one person or species to another.
Rationale: A communicable disease is defined by its transmissibility, meaning it can be transmitted from an infected host to
a susceptible one, either directly or
indirectly. This characteristic distinguishes it from non-communicable diseases that are not spread between individuals.
QUESTION 2
Infectious disease
Answer: A disease that is caused by a pathogen and that can be spread from one individual to another.
Rationale: An infectious disease is defined by its etiology as a pathological condition stemming from a specific pathogen,
and its characteristic transmission capability between hosts. This highlights the dual criteria of causative agent and
communicability that distinguish infectious from non-infectious illnesses.
QUESTION 3
Prenatal exposure to alcohol includes
Answer: ND-PAE, decreased brain function, FAS.
Rationale: Prenatal alcohol exposure can result in neurodevelopmental disorders such as Neurobehavioral Disorder
Associated with Prenatal Alcohol Exposure (NDPAE), characterized by decreased brain function, and Fetal Alcohol
Syndrome (FAS), a more severe presentation. The key concept tested is the spectrum of adverse outcomes associated with
maternal alcohol consumption during pregnancy.

QUESTION 4
Conditions that lead to COPD
Answer: Smoking, asthma, dust, chemicals, genetics.
Rationale: Chronic obstructive pulmonary disease (COPD) is primarily caused by long-term exposure to irritants like
tobacco smoke, air pollution, and occupational dusts or chemicals, with genetic factors such as alpha-1 antitrypsin
deficiency also contributing to disease development. The key concept tested is the multifactorial etiology of COPD,
encompassing both environmental exposures and inherited predispositions.
QUESTION 5
Lyme disease
Answer: Tick-borne disease caused by the spirochete Borrelia burgdorferi.
Rationale: Lyme disease is an infectious illness transmitted by infected ticks, specifically caused by the spiral-shaped
bacterium *Borrelia burgdorferi*. This etiology defines its classification as a tick-borne spirochetal infection.
QUESTION 6
Erythema infectiosum
Answer: A febrile upper respiratory illness in a child followed by the sudden appearance of red, flushed
cheeks, "fifth disease".
Rationale: Erythema infectiosum, commonly known as fifth disease, is characterized by a prodromal febrile upper
respiratory illness followed by a distinctive erythematous rash on the cheeks. This presentation confirms the diagnosis by
linking the characteristic rash to its common antecedent symptoms.
QUESTION 7
Decubitus ulcer
Answer: Sore caused by lying down for long periods of time.
Rationale: A decubitus ulcer, or pressure injury, is skin breakdown resulting from sustained pressure, typically over bony
prominences, that impedes circulation. This prolonged ischemia leads to tissue necrosis and ulceration.
