Difficulty Level: Dynamically Determined Based on Exam Scope
==============================
SECTION 1: Advanced Assessment and Differential Diagnosis
Question 1: A 58-year-old male presents with crushing substernal chest pain radiating to
the left arm, diaphoresis, and nausea. Vital signs are BP 88/52 mmHg, HR 110 bpm, RR
24/min, SpO2 91% on room air. Which immediate intervention takes priority?
A. Administer sublingual nitroglycerin
B. Obtain a 12-lead ECG within 10 minutes
C. Administer aspirin 325 mg chewable
D. Initiate IV morphine for pain relief
Correct Answer: B
,Rationale: In a patient with suspected acute coronary syndrome, obtaining a 12-lead
ECG within 10 minutes is the priority to identify ST-elevation myocardial infarction and
guide immediate reperfusion therapy. While aspirin and pain management are
important, ECG acquisition must not be delayed as it determines the pathway for
emergent percutaneous coronary intervention.
Question 2: A 42-year-old female with type 1 diabetes presents with polyuria, polydipsia,
fruity breath odor, and Kussmaul respirations. Laboratory studies reveal glucose 420
mg/dL, pH 7.18, bicarbonate 12 mEq/L, and anion gap 22. Which electrolyte abnormality
requires the most careful monitoring during initial treatment?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hyponatremia
Correct Answer: B
Rationale: During diabetic ketoacidosis treatment, insulin administration drives
potassium intracellularly, and fluid resuscitation dilutes serum potassium. Despite initial
hyperkalemia due to acidosis, total body potassium is depleted. Hypokalemia can
precipitate fatal cardiac arrhythmias and must be monitored closely with aggressive
potassium replacement as insulin therapy progresses.
,Question 3: A 67-year-old patient with a history of atrial fibrillation on warfarin presents
with sudden onset of left-sided weakness, facial droop, and slurred speech. The last
known well time was 90 minutes ago. INR is 2.8. Which action is most appropriate?
A. Administer IV alteplase immediately
B. Obtain emergent CT head without contrast
C. Give IV vitamin K and fresh frozen plasma
D. Start aspirin 325 mg orally
Correct Answer: B
Rationale: The first step in suspected acute ischemic stroke is emergent non-contrast
CT head to differentiate ischemic from hemorrhagic stroke before any thrombolytic or
antithrombotic intervention. Alteplase is contraindicated with an INR greater than 1.7,
and aspirin should not be given until hemorrhage is excluded.
Question 4: A 35-year-old female presents with fatigue, weight gain, cold intolerance,
constipation, and dry skin. Laboratory studies show TSH 12.5 mIU/L and free T4 0.6
ng/dL. Which physical examination finding is most consistent with this diagnosis?
A. Exophthalmos and pretibial myxedema
B. Bradycardia and delayed deep tendon reflex relaxation
C. Tremor and lid lag
D. Tachycardia and warm moist skin
Correct Answer: B
, Rationale: These laboratory values indicate primary hypothyroidism. Bradycardia and
delayed relaxation phase of deep tendon reflexes are classic physical findings in
hypothyroidism due to decreased metabolic rate and reduced tissue responsiveness.
Exophthalmos and tremor are associated with hyperthyroidism.
Question 5: A 55-year-old male with chronic obstructive pulmonary disease presents
with worsening dyspnea, increased sputum production, and purulent sputum. Arterial
blood gas on room air shows pH 7.32, PaCO2 58 mmHg, PaO2 62 mmHg, and HCO3 30
mEq/L. Which acid-base disorder is present?
A. Acute respiratory acidosis
B. Chronic respiratory acidosis with metabolic compensation
C. Metabolic alkalosis
D. Mixed respiratory and metabolic acidosis
Correct Answer: B
Rationale: The elevated PaCO2 with near-normal pH and elevated bicarbonate indicates
chronic respiratory acidosis with renal compensation. The bicarbonate has risen to
compensate for the chronic CO2 retention, maintaining pH near normal. This pattern is
typical in stable COPD patients with chronic hypercapnia.
Question 6: A 48-year-old female presents with severe epigastric pain radiating to the
back, nausea, and vomiting. She has a history of heavy alcohol use. Laboratory studies
show lipase 1200 U/L and amylase 950 U/L. CT abdomen reveals pancreatic edema
