stroke. He is being cared for at home and has home health
assistance. Residual effects of his stroke include dysphasia and

secondary to fever, chills, and productive cough. His CXR
demonstrates the following: What is the most likely cause of
this finding?
A. COPD
B. bacterial pneumonia
C. viral pneumonia
D. aspiration pneumonia
D. aspiration pneumonia
Rationale: This patient has aspiration pneumonia. That is
evident by the collection in the right base of the lung. With his
past medical history significant for ischemic stroke in
,dysphasia, aspiration has to be high on the differential list for
this patient.
A 72-year-old male with a past history of CAD, HTN, HLD,
tobacco use, and Type 2 DM presents to the ED with complaints
of sudden onset of severe pain to his left lower leg that started
about two hours earlier. Vital signs are as follows: BP 148/92,
HR 105, T 99.1 F. Lab work is notable for lactic acid of 3.4 and
CBC with WBC count of 14,000. Physical exam reveals cool, pale

his toes or his calf. Which of the following is the suspected
diagnosis?

D. acute limb ischemia.
D. acute limb ischemia.
Rationale: The patient has evidence of a cold leg without
sensation that occurred after severe acute pain of the leg
,before admission. He has lactic acidosis and a lack of
peripheral pulses on doppler ultrasound. This represents
acute limb ischemia.
