USMLE Sample Questions
Based on the National Board of Medical Examiners format.
A 70-year-old woman presents with right-sided severe headache associated with nausea, vomiting, eye pain, and blurred vision. She states her symptoms started shortly after entering her car at night. She reports seeing halos around the traffic lights. Her past medical history is remarkable only for hypertension.
On examination, the patient appears uncomfortable. Vital signs are normal. The left conjunctiva is clear with a grossly clear cornea and reactive pupil. The right eye is remarkable for diffuse conjunctival injection, a cloudy cornea, and a nonreactive mid-dilated pupil. Visual acuity is 20/40 OS and 20/200 OD. Neurologic examination findings are otherwise normal, including intact extraocular movements.
Which of the follow statements is true regarding this patient’s most likely diagnosis?
Challenging distractors are one of the most important features of a high quality USMLE exam review question.
Relief of the headache with oxygen is diagnostic.
Tonometry will confirm the diagnosis.
Erythrocyte sedimentation rate (ESR) will confirm the diagnosis.
Computed tomography (CT) of the brain will confirm the diagnosis.
Understanding why an answer choice is incorrect is just as important as knowing why it is correct for a truly effective medical student exam review course.
Tonometry will confirm the diagnosis.
Discuss findings of acute angle closure glaucoma in comparison with other serious causes of unilateral headaches.
Acute eye pain, headache, and vision disturbance precipitated by pupillary dilation (entrance into low light environment) associated with a red eye, cloudy cornea, fixed mid-dilated pupil, and firm globe is consistent with acute angle closure glaucoma.
Acute angle closure glaucoma, temporal arteritis, cluster headache, and migraine headache all may present with unilateral headache and vision disturbance with or without nausea and vomiting. Tonometry is diagnostic for acute angle closure glaucoma—an elevated intraocular pressure (IOP; typically 40-80 mm Hg) confirms glaucoma and thereby excludes the other options.
An elevated ESR is a diagnostic criterion for temporal arteritis. Termination of the headache with oxygen suggests an etiology of cluster headache. In addition, younger age at onset and miosis (rather than mydriasis) are expected with cluster headache, not acute angle closure glaucoma. CT is not diagnostic of glaucoma.
