1. Which of the following is a potential complication of tympanostomy tube placement for Eustachian
tube dysfunction?
a) Hearing loss
b) Chronic ear infections
c) Nasal bleeding
d) Ear drainage
*Answer: b) Chronic ear infections*
Rationale: Tympanostomy tube placement can lead to chronic ear infections as a complication due to
the presence of a foreign body in the ear.
2. What is the rationale behind using autoinsufflation as a treatment for Eustachian tube dysfunction?
a) To stimulate the auditory nerve
b) To manually remove earwax
c) To equalize middle ear pressure
d) To improve inner ear circulation
*Answer: c) To equalize middle ear pressure*
Rationale: Autoinsufflation helps equalize middle ear pressure by gently forcing air through the
Eustachian tube, potentially relieving symptoms of Eustachian tube dysfunction.
3. Which of the following is a recommended follow-up procedure after using nasal steroids for
Eustachian tube dysfunction?
a) Immediate tympanostomy tube removal
b) Hearing testing after 2 weeks
c) Follow-up in 3 weeks
,d) No follow-up necessary
*Answer: c) Follow-up in 3 weeks*
Rationale: Follow-up in 3 weeks after using nasal steroids helps assess the effectiveness of treatment
and the resolution of symptoms of Eustachian tube dysfunction.
4. What is the primary inflammatory response associated with allergic rhinitis (AR)?
a) Mast cell degranulation
b) Neutrophil activation
c) Macrophage proliferation
d) T-cell infiltration
*Answer: a) Mast cell degranulation*
Rationale: Allergic rhinitis involves mast cell hypersensitivity mediated by immunoglobulin E (IgE),
leading to mast cell degranulation and the release of inflammatory mediators.
5. Which of the following is a characteristic symptom of nonallergic rhinitis?
a) Severe sneezing
b) Thick nasal discharge
c) Itching of the eyes
d) Perennial nasal congestion
*Answer: d) Perennial nasal congestion*
Rationale: Nonallergic rhinitis typically presents with perennial nasal congestion triggered by
environmental factors, unlike the seasonal symptoms commonly associated with allergic rhinitis.
C. How is the diagnosis of allergic rhinitis (AR) primarily established?
a) Radiological imaging
b) Nasal endoscopy
c) Radioallergosorbent tests (RASTs)
,d) Electrocardiography
*Answer: c) Radioallergosorbent tests (RASTs)*
Rationale: Diagnosis of allergic rhinitis is clinically based, and tests such as radioallergosorbent tests
(RASTs), scratch/patch tests, and nasal cytology may be used to confirm allergen sensitivities.
6. What is a recommended management strategy for nonallergic rhinitis?
a) Oral antihistamines
b) Intranasal steroids
c) Environmental control
d) Immunotherapy
*Answer: c) Environmental control*
Rationale: Nonallergic rhinitis management primarily involves avoiding triggers and using measures like
saline irrigation and intranasal steroids to alleviate symptoms.
7. What complication is associated with allergic rhinitis (AR)?
a) Increased risk of pneumonia
b) Higher prevalence of diabetes
c) Elevated incidence of hypertension
d) Increased asthma exacerbations
*Answer: d) Increased asthma exacerbations*
Rationale: Complications of allergic rhinitis include increased asthma exacerbations due to the close
association between the two conditions, often termed "allergic asthma-rhinitis syndrome."
8. What is rhinitis?
a) A gastrointestinal condition
b) An inflammation of the sinus nasal cavity
c) A skin disorder
, d) A bone disease
Answer: b) An inflammation of the sinus nasal cavity
Rationale: Rhinitis refers to inflammation of the sinus nasal cavity.
9 Which of the following best defines translational research?
a) The process of moving knowledge from clinical practice to research.
b) Assessing evidence validity, applicability, and practicality through a grading system.
c) Defining the need for change in clinical practice without evidence-based interventions.
d) Implementing evidence-driven changes without critique or collaboration.
Answer: b) Assessing evidence validity, applicability, and practicality through a grading system.
Rationale: Translational research involves assessing evidence validity, applicability, and practicality
through a grading and critique system, which distinguishes it from other approaches.
10 What is the primary role of Primary Care Providers (PCPs) in the translational research process?
a) Conducting randomized controlled trials.
b) Defining the need for change and questioning established policies.
c) Implementing changes without considering empirical evidence.
d) Seeking assistance from medical science librarians only when necessary.
Answer: b) Defining the need for change and questioning established policies.
Rationale: PCPs initiate the translational research process by defining the need for change and
questioning established policies or procedures, which marks the beginning of evidence-driven practice
changes.
How does translational research differ from traditional approaches?
a) It disregards evidence-based interventions.
b) It excludes medical science librarians from the process.
c) It is not concerned with the validity of research findings.
d) It shapes standards based on evidence from empirical research findings.
