Question 1:
A physician has directly examined a patient’s paranasal sinuses. Which of the
following sinuses is most likely to be assessed through direct palpation under the
cheekbones?
A. Ethmoidal sinuses
B. Frontal sinuses
C. Maxillary sinuses
D. Sphenoidal sinuses
Correct Answer: C. Maxillary sinuses
Rationale: The maxillary sinuses are located beneath the cheekbones and are
accessible through palpation and percussion during physical examination. Frontal
sinuses are located above the eyebrows, ethmoidal sinuses are between the eyes and
are not directly palpated, and sphenoidal sinuses are deep within the skull and cannot
be accessed through routine physical examination.
Question 2:
Olfactory receptors responsible for the sense of smell are located in which anatomical
region?
A. Nasal vestibule
B. Inferior nasal turbinate
C. Upper nasal cavity mucosa
D. Nasopharynx
Correct Answer: C. Upper nasal cavity mucosa
Rationale: Olfactory receptors are located in the olfactory epithelium within the
superior portion of the nasal cavity. The nasal vestibule and turbinates are primarily
,2026/2027
involved in air filtration and humidification, while the nasopharynx serves as an
airway passage and is not involved in smell perception.
Question 3:
Which medication class is diphenhydramine?
A. Decongestant
B. Antihistamine
C. Expectorant
D. Antitussive
Correct Answer: B. Antihistamine
Rationale: Diphenhydramine is a first-generation antihistamine used to treat allergic
reactions by blocking histamine receptors. Decongestants reduce nasal swelling,
expectorants loosen mucus, and antitussives suppress coughing.
Question 4:
A patient develops nasal congestion after starting a new medication. Which drug is
most likely responsible?
A. Beta blockers
B. Aspirin
C. Ginkgo biloba
D. Vitamin D supplements
Correct Answer: A. Beta blockers
Rationale: Beta blockers can cause nasal congestion as a side effect due to
vasoconstrictive effects on nasal mucosa. Aspirin may cause respiratory sensitivity in
some patients but not typical congestion. Ginkgo biloba and vitamin D are not
commonly associated with nasal congestion.
Question 5:
A patient presents with pale, swollen (boggy) nasal turbinates. What is the most likely
cause?
A. Acute bacterial infection
B. Allergic rhinitis
C. Nasal trauma
D. Dehydration
,2026/2027
Correct Answer: B. Allergic rhinitis
Rationale: Pale, boggy turbinates are classic findings in allergic rhinitis due to
histamine-mediated vasodilation and inflammation. Infections typically cause
erythema and purulent discharge rather than pale swelling.
Question 6:
A patient has symptoms of sinus pain, eczema, and allergic rhinitis. Which diagnostic
test is safest and most appropriate for identifying specific allergens?
A. Skin prick test
B. RAST test
C. CT scan of sinuses
D. CBC with differential only
Correct Answer: B. RAST test
Rationale: The RAST test detects specific IgE antibodies in the blood and is safe for
patients at risk of severe allergic reactions. Skin testing carries risk of anaphylaxis.
CT scans evaluate structure, and CBC provides nonspecific inflammatory markers.
Question 7:
A pregnant woman reports frequent nosebleeds. What is the primary physiological
cause?
A. Decreased estrogen
B. Increased vascularity of nasal mucosa
C. Reduced blood pressure
D. Iron deficiency anemia
Correct Answer: B. Increased vascularity of nasal mucosa
Rationale: Pregnancy increases estrogen and blood volume, causing vascular
engorgement of nasal tissues, making them prone to bleeding. Decreased estrogen and
hypotension are incorrect, and anemia may contribute but is not primary.
Question 8:
Which sequence correctly describes airflow through the pharynx?
A. Oropharynx → nasopharynx → laryngopharynx
B. Nasopharynx → oropharynx → laryngopharynx
, 2026/2027
C. Laryngopharynx → nasopharynx → oropharynx
D. Nasopharynx → larynx → esophagus
Correct Answer: B. Nasopharynx → oropharynx → laryngopharynx
Rationale: Air passes from the nasal cavity into the nasopharynx, then oropharynx,
and finally the laryngopharynx before entering the larynx. The other sequences
incorrectly reverse or bypass anatomical structures.
Question 9:
A patient with bacterial pharyngitis is most likely to report which symptom?
A. Mild scratchy throat
B. Sudden severe throat pain
C. Intermittent throat clearing
D. Painless swallowing difficulty
Correct Answer: B. Sudden severe throat pain
Rationale: Bacterial pharyngitis typically presents with acute onset of severe throat
pain that may interfere with swallowing. Mild scratchiness is more consistent with
viral infections.
Question 10:
Smoking affects gingival tissue primarily through which mechanism?
A. Vasodilation
B. Vasoconstriction
C. Increased saliva production
D. Tissue regeneration
Correct Answer: B. Vasoconstriction
Rationale: Nicotine causes vasoconstriction, reducing blood flow to gingival tissues
and impairing healing. This increases the risk of periodontal disease.
Question 11:
Which oral finding is considered a normal age-related change in older adults?
A. Increased saliva production
B. Varicosities under the tongue
