1.
A 55-year-old patient with long-standing hypertension presents with gradual
decline in renal function. Which finding most strongly supports hypertensive
nephrosclerosis as the cause?
A. Heavy proteinuria
B. Asymmetric kidney size
C. Enlarged kidneys with cysts
D. Rapid onset hematuria
Correct Answer: B
Rationale:
Hypertensive nephrosclerosis typically causes progressive ischemic damage,
leading to small, scarred, often asymmetric kidneys. Heavy proteinuria suggests
glomerular disease, while enlarged cystic kidneys suggest polycystic disease.
,2.
Which dental structure is derived from ectoderm during tooth development?
A. Dental pulp
B. Cementum
C. Enamel
D. Dentin
Correct Answer: C
Rationale:
Enamel originates from oral ectoderm, while dentin, pulp, and cementum arise
from mesenchymal (neural crest) cells.
3.
A patient with poorly controlled diabetes presents with facial swelling, nasal
congestion, and black eschar on the palate. The most likely diagnosis is:
A. Actinomycosis
B. Invasive aspergillosis
C. Mucormycosis
D. Oral candidiasis
Correct Answer: C
Rationale:
Mucormycosis is a life-threatening fungal infection seen in uncontrolled
diabetes, characterized by tissue necrosis and black eschar, especially in the
sinuses and palate.
4.
Which medication is most appropriate for acute anaphylaxis?
A. Diphenhydramine
B. Hydrocortisone
,C. Epinephrine
D. Albuterol
Correct Answer: C
Rationale:
Epinephrine is the first-line, life-saving treatment for anaphylaxis due to its
rapid effects on bronchoconstriction, hypotension, and edema.
5.
A panoramic radiograph shows a well-defined radiolucency surrounding the crown
of an unerupted mandibular third molar. The most likely diagnosis is:
A. Radicular cyst
B. Dentigerous cyst
C. Odontogenic keratocyst
D. Ameloblastoma
Correct Answer: B
Rationale:
A dentigerous cyst forms around the crown of an unerupted tooth, most
commonly third molars.
6.
Which laboratory finding is most consistent with iron deficiency anemia?
A. Elevated ferritin
B. Increased mean corpuscular volume
C. Decreased transferrin saturation
D. Elevated reticulocyte count
Correct Answer: C
Rationale:
Iron deficiency anemia is characterized by low ferritin, low transferrin
saturation, and microcytosis, with a low reticulocyte response.
, 7.
Which nerve provides sensory innervation to the maxillary teeth?
A. Inferior alveolar nerve
B. Lingual nerve
C. Greater palatine nerve
D. Posterior superior alveolar nerve
Correct Answer: D
Rationale:
The posterior superior alveolar nerve, a branch of the maxillary division of the
trigeminal nerve (V2), supplies the maxillary molars and premolars.
8.
A patient receiving long-term corticosteroid therapy is at greatest risk for which
complication?
A. Hyperkalemia
B. Osteoporosis
C. Hypoglycemia
D. Bradycardia
Correct Answer: B
Rationale:
Chronic corticosteroid use leads to bone resorption, decreased calcium
absorption, and osteoporosis, increasing fracture risk.
9.
Which oral lesion is considered potentially malignant?
A. Aphthous ulcer
B. Leukoplakia
