BIM INTERNAL MEDICINE ITE EXAM
Question 1: A 65-year-old male presents to the emergency department
with sudden onset of severe chest pain radiating to his left arm. He has a
history of hypertension, diabetes mellitus type 2, and hyperlipidemia.
His ECG shows ST-segment elevation in leads II, III, and aVF. Which
coronary artery is most likely occluded?
A) Left anterior descending artery B) Right coronary artery C) Left
circumflex artery D) Posterior descending artery
The right coronary artery supplies the inferior wall of the heart, which
corresponds to leads II, III, and aVF on ECG. The left anterior
descending artery would affect the anterior wall (leads V1-V4), while
the left circumflex affects the lateral wall (leads I, aVL, V5, V6).
Question 2: A 45-year-old female with a history of Graves' disease
presents with palpitations, tremor, weight loss, and heat intolerance. Her
TSH is <0.01 mIU/L and free T4 is elevated at 3.8 ng/dL. Which
medication should be initiated first for symptomatic relief?
A) Methimazole B) Radioactive iodine C) Propranolol D)
Propylthiouracil
Beta-blockers like propranolol provide immediate symptomatic relief
from adrenergic symptoms such as tachycardia, tremor, and anxiety in
thyrotoxicosis. Antithyroid medications take weeks to become effective,
and radioactive iodine is not used for acute symptom control.
Question 3: A 72-year-old male with COPD presents with increased
dyspnea, productive cough with yellow sputum, and low-grade fever. His
oxygen saturation is 88% on room air. Which intervention should be
prioritized?
,A) Initiate broad-spectrum antibiotics immediately B) Administer
supplemental oxygen to maintain SpO2 88-92% C) Start systemic
corticosteroids D) Perform arterial blood gas analysis
In COPD patients, oxygen should be titrated carefully to maintain
saturation between 88-92% to avoid suppressing respiratory drive and
causing CO2 retention. While antibiotics and steroids may be needed,
oxygen therapy addresses the immediate life-threatening hypoxemia.
Question 4: A 58-year-old female presents with fatigue, pallor, and
paresthesias in her hands and feet. Laboratory studies show hemoglobin
8.2 g/dL, MCV 112 fL, and serum vitamin B12 level of 120 pg/mL. What
is the most appropriate initial treatment?
A) Oral iron supplementation B) Folic acid supplementation C)
Parenteral vitamin B12 injections D) Oral vitamin B12 tablets
Severe vitamin B12 deficiency with neurological symptoms requires
parenteral replacement initially to ensure adequate absorption and
rapid correction. Oral supplementation may be considered for
maintenance after initial repletion, but neurological symptoms
mandate aggressive initial therapy.
Question 5: A 35-year-old male presents with acute onset of severe
headache, neck stiffness, photophobia, and fever. Lumbar puncture
reveals cloudy CSF with WBC 1,200/mm³ (90% neutrophils), glucose 35
mg/dL, and protein 180 mg/dL. What is the most likely diagnosis?
A) Viral meningitis B) Bacterial meningitis C) Tuberculous
meningitis D) Fungal meningitis
Bacterial meningitis typically presents with high neutrophil count, low
glucose, and elevated protein in CSF. Viral meningitis usually has
lymphocytic predominance and normal glucose levels. The acute
presentation and CSF findings are classic for bacterial etiology.
Question 6: A 60-year-old male with a history of alcohol use disorder
presents with hematemesis and melena. Endoscopy reveals large
esophageal varices with active bleeding. Which medication should be
administered immediately?
A) Pantoprazole IV B) Octreotide IV C) Metoclopramide D) Sucralfate
Octreotide reduces portal pressure by causing splanchnic
vasoconstriction, which is critical in controlling acute variceal bleeding.
,Proton pump inhibitors do not address the underlying portal
hypertension mechanism in variceal bleeding.
Question 7: A 50-year-old female presents with progressive proximal
muscle weakness, difficulty climbing stairs, and a heliotrope rash on her
eyelids. Creatine kinase is elevated at 2,400 U/L. What is the most likely
diagnosis?
A) Polymyalgia rheumatica B) Dermatomyositis C) Systemic lupus
erythematosus D) Hypothyroid myopathy
Dermatomyositis presents with characteristic skin findings (heliotrope
rash, Gottron's papules) along with symmetric proximal muscle
weakness and elevated muscle enzymes. The combination of cutaneous
and muscular involvement distinguishes it from polymyositis.
Question 8: A 28-year-old pregnant woman at 32 weeks gestation
presents with new-onset hypertension (BP 150/95 mmHg), proteinuria,
and headache. Platelet count is 95,000/mm³ and liver enzymes are
elevated. What is the definitive treatment?
A) Magnesium sulfate infusion B) Labetalol administration C) Delivery
of the fetus D) Corticosteroid administration
This patient has HELLP syndrome (Hemolysis, Elevated Liver enzymes,
Low Platelets), a severe form of preeclampsia. Delivery is the only
definitive treatment, though magnesium sulfate is given for seizure
prophylaxis and antihypertensives for blood pressure control.
Question 9: A 42-year-old male presents with episodic headaches,
diaphoresis, and palpitations. Blood pressure readings during episodes
reach 220/120 mmHg. Plasma metanephrines are markedly elevated.
What diagnostic test should be performed next?
A) Renal ultrasound B) CT or MRI of the abdomen C)
Echocardiogram D) Thyroid function tests
Elevated metanephrines confirm pheochromocytoma. Imaging of the
abdomen (typically CT or MRI) is required to localize the tumor, which
is usually found in the adrenal glands. Biochemical confirmation
precedes anatomical localization.
Question 10: A 67-year-old male with atrial fibrillation on warfarin
presents with INR of 6.2 but no active bleeding. What is the most
appropriate management?
, A) Administer fresh frozen plasma B) Give vitamin K 10 mg IV C) Hold
warfarin and give oral vitamin K 1-2.5 mg D) Continue current
warfarin dose
For supratherapeutic INR without bleeding, holding warfarin and
administering low-dose oral vitamin K is appropriate. High-dose IV
vitamin K or FFP is reserved for active bleeding or extremely high INR
values (>10).
Question 11: A 55-year-old female presents with jaundice, pruritus, and
dark urine. Laboratory studies show alkaline phosphatase 450 U/L, total
bilirubin 4.2 mg/dL, and AST/ALT mildly elevated. Ultrasound reveals
dilated intrahepatic bile ducts. What is the next best step?
A) Liver biopsy B) MRCP or ERCP C) Hepatitis serologies D) Serum
ceruloplasmin
Cholestatic pattern with dilated bile ducts suggests biliary obstruction.
MRCP (non-invasive) or ERCP (therapeutic potential) can visualize and
potentially treat the obstruction. This pattern differs from
hepatocellular injury where transaminases would be more significantly
elevated.
Question 12: A 30-year-old male presents with recurrent episodes of
severe abdominal pain, constipation, and psychiatric symptoms. During
attacks, his urine turns dark upon standing. What is the most likely
diagnosis?
A) Lead poisoning B) Acute intermittent porphyria C) Hereditary
coproporphyria D) Wilson's disease
Acute intermittent porphyria presents with the classic triad of
abdominal pain, neuropsychiatric symptoms, and dark urine (due to
porphobilinogen oxidation). Lead poisoning can cause similar
symptoms but typically presents with anemia and basophilic stippling.
Question 13: A 48-year-old male with HIV (CD4 count 85 cells/mm³)
presents with subacute onset of headache, confusion, and focal
neurological deficits. Brain MRI shows multiple ring-enhancing lesions.
What is the most likely diagnosis?
A) Primary CNS lymphoma B) Toxoplasmosis C) Cryptococcal
meningitis D) Progressive multifocal leukoencephalopathy
In HIV patients with CD4 <100, toxoplasmosis commonly presents with
multiple ring-enhancing brain lesions. Primary CNS lymphoma
