Practice-material note: The following is an original, study-focused question bank
designed around the stated BIOL122 topics. It is not an actual Australian Catholic
University assessment, does not reproduce proprietary assessment questions, and
should not be treated as a guarantee of a particular grade.
INTRODUCTION
This comprehensive BIOL122 Human Biological Science 2 practice question bank is
designed to support preparation for Assessment 2 Vodcast work involving extrinsic
asthma and type 2 diabetes mellitus, with emphasis on pathophysiology,
pharmacology, clinical reasoning, evidence interpretation, and scientific
communication. The questions move beyond simple recall and require students to
integrate physiological mechanisms with clinical case information and therapeutic
decision-making. Particular attention is given to airway inflammation and
hyperresponsiveness in asthma, insulin resistance and progressive β-cell dysfunction
in type 2 diabetes, medication mechanisms, adverse effects, monitoring, and the
relationship between disease processes and homeostasis. The bank also incorporates
skills relevant to an academic vodcast, including interpretation of research evidence,
distinguishing primary from secondary evidence, constructing defensible clinical
explanations, and selecting appropriate information for an annotated bibliography.
Each question has one best answer followed by a detailed rationale explaining the
underlying reasoning and why the alternatives are less appropriate. Used alongside
lecture material, prescribed readings, and current ACU assessment instructions, these
questions can help students identify knowledge gaps and develop stronger
application-level responses.

QUESTIONS 1–100
Q1.
A patient with extrinsic asthma develops wheezing shortly after exposure to a known
airborne allergen. Which mechanism most directly explains the rapid onset of
bronchoconstriction?
A) Increased alveolar surfactant production
B) Reduced pulmonary blood flow
C) Mast-cell mediator release causing airway smooth-muscle contraction
D) Increased erythropoietin secretion
3
, Rationale: C is correct because allergen exposure in sensitised individuals can cross-
link IgE on mast cells, triggering mediator release such as histamine and leukotrienes.
These mediators promote bronchoconstriction and contribute to airway oedema and
mucus production. A is incorrect because surfactant primarily reduces alveolar
surface tension and does not cause acute bronchoconstriction. B does not explain the
initial airway narrowing. D regulates erythrocyte production and is unrelated to the
immediate asthmatic response.
Q2.
A student preparing a BIOL122 vodcast states that extrinsic asthma is primarily
caused by irreversible destruction of alveolar walls. Which correction is most
appropriate?
A) Asthma is primarily a disease of reduced red-cell production.
B) Asthma involves variable airway obstruction associated with inflammation
and airway hyperresponsiveness.
C) Asthma results exclusively from pulmonary vascular obstruction.
D) Asthma is caused by permanent loss of alveolar surfactant.
Rationale: B is correct because asthma characteristically involves airway
inflammation, bronchial hyperresponsiveness, bronchoconstriction, and variable
airflow limitation. A, C, and D describe mechanisms unrelated to the defining
pathophysiology of asthma. Emphysematous alveolar-wall destruction is more
characteristic of emphysema than asthma.
Q3.
A patient with allergic asthma has increased eosinophilic inflammation in the
bronchial mucosa. Which consequence would most directly contribute to persistent
airway hyperresponsiveness?
A) Increased alveolar elasticity
B) Inflammatory injury and mediator release within the airway wall
C) Increased haemoglobin synthesis
D) Reduced pulmonary capillary filtration
Rationale: B is correct because eosinophils and other inflammatory cells release
mediators that damage airway epithelium and amplify bronchial sensitivity. A would
not explain airway hyperresponsiveness. C affects oxygen transport rather than
airway reactivity. D is not the principal mechanism producing bronchial
hyperresponsiveness.
Q4.
An allergen activates a previously sensitised patient's immune system. Which
antibody is most strongly associated with the classic immediate hypersensitivity
mechanism underlying extrinsic asthma?
