Question 1
A 62-year-old patient with long-standing hypertension presents with progressive
exertional dyspnea and bilateral ankle edema. Echocardiography reveals concentric
left ventricular hypertrophy with preserved ejection fraction. What is the most
likely diagnosis?
A. Dilated cardiomyopathy
B. Heart failure with preserved ejection fraction
C. Acute cor pulmonale
D. Restrictive cardiomyopathy
Correct Answer: B
Rationale: Long-standing hypertension commonly leads to concentric hypertrophy
and diastolic dysfunction, resulting in heart failure with preserved ejection fraction
despite normal systolic function.
,Question 2
A dental patient receiving long-term bisphosphonate therapy reports jaw pain and
exposed bone following tooth extraction. What is the most likely complication?
A. Alveolar osteitis
B. Osteoradionecrosis
C. Medication-related osteonecrosis of the jaw
D. Chronic periodontitis
Correct Answer: C
Rationale: Bisphosphonates impair bone remodeling and are associated with
medication-related osteonecrosis of the jaw, particularly after invasive dental
procedures.
Question 3
A patient presents with sudden-onset severe headache, neck stiffness, and
photophobia. CT scan of the head is normal. What is the next most appropriate
diagnostic step?
A. MRI of the brain
B. Lumbar puncture
C. Cerebral angiography
D. EEG
Correct Answer: B
Rationale: In suspected subarachnoid hemorrhage with a normal CT scan, lumbar
puncture is necessary to detect xanthochromia or red blood cells in cerebrospinal
fluid.
,Question 4
Which oral lesion is most strongly associated with tobacco use and has a high risk
of malignant transformation?
A. Aphthous ulcer
B. Leukoplakia
C. Oral candidiasis
D. Lichen planus
Correct Answer: B
Rationale: Leukoplakia is a premalignant lesion strongly linked to tobacco use and
carries a significant risk of progression to oral squamous cell carcinoma.
Question 5
A patient with poorly controlled diabetes presents with fever, facial pain, black
nasal discharge, and palatal necrosis. What is the most likely diagnosis?
A. Acute bacterial sinusitis
B. Invasive candidiasis
C. Mucormycosis
D. Wegener granulomatosis
Correct Answer: C
Rationale: Mucormycosis is a life-threatening fungal infection seen in
immunocompromised patients, especially those with uncontrolled diabetes,
characterized by tissue necrosis.
Question 6
Which electrolyte abnormality is most commonly associated with prolonged QT
interval on ECG?
A. Hyperkalemia
B. Hypokalemia
, C. Hypercalcemia
D. Hypermagnesemia
Correct Answer: B
Rationale: Hypokalemia delays ventricular repolarization, leading to QT interval
prolongation and increased risk of arrhythmias.
Question 7
A child presents with delayed eruption of teeth, retained primary teeth, and
multiple impacted permanent teeth. Which condition is most likely?
A. Cleidocranial dysplasia
B. Down syndrome
C. Amelogenesis imperfecta
D. Osteogenesis imperfecta
Correct Answer: A
Rationale: Cleidocranial dysplasia is characterized by delayed tooth eruption,
supernumerary teeth, and skeletal abnormalities including clavicular hypoplasia.
Question 8
Which arterial blood gas finding is expected in acute pulmonary embolism?
A. Respiratory acidosis with hypercapnia
B. Metabolic acidosis with normal oxygenation
C. Respiratory alkalosis with hypoxemia
D. Normal pH with hyperoxia
Correct Answer: C
Rationale: Acute pulmonary embolism typically causes hyperventilation leading
to respiratory alkalosis, along with impaired gas exchange resulting in hypoxemia.
