Question #33

A 48-year-old woman presents to the office with a 3-week history of progressive shortness of breath. She does not drink or smoke. She had been in generally good health until she began losing weight about 2 months ago. One week ago she began vomiting after meals. Her family history is unremarkable. She is afebrile, and on chest examination she has dullness to percussion, decreased breath sounds without egophany at the right base. Her abdominal exam is unremarkable with no tenderness to palpation, no hepatosplenomegaly and normal bowel sounds. Wisely, you decide to get a chest x-ray:

You proceed with some laboratory studies:

Serum values:

Hct=37% WBC=8,700 N67 L20 M10 E3 Amylase=86 Total protein=6.2 LDH=210

Thoracentesis values:

RBC=110,000 WBC=1,100 Mono70 Neut20 Meso10 Protein=4.3 LDH=300 Amylase=450 pH=7.43 Cytology=negative

The most likely diagnosis is:

  1. A small esophageal rupture
  2. Pancreatitis
  3. A pancreatic pseudocyst
  4. Pleural adenocarcinoma
  5. Tuberculous pleurisy

Explanation


Question #34

A 45-year-old man presents to you with the following leg ulcer of the lateral calf:

He has had this lesion going on 3-4 months. It is minimally painful and has failed soaking in water, wrapping it with bandages, cleaning with hydrogen peroxide or applying bacitracin. Being the astute clinician you do a complete history and on review of systems you also get a history of arthralgias and occasional bloody diarrhea over the past few years. On exam, he does have some evidence of synovitis in diffuse joints but otherwise the physical exam is unremarkable.

The most likely diagnosis is

  1. Venous insufficiency ulcer
  2. Pyoderma gangenosum
  3. Ulceration of squamous cell carcinoma
  4. Necrotizing vasculitis
  5. Ulceration associated with arterial insufficiency

Explanation


Question #35

You are seeing a 43-year-old woman for a health maintenance checkup. She is generally healthy with no history of coronary heart disease. She does have a positive family history for myocardial infarction in a 53-year-old brother and 59-year-old sister. She smokes 1 pack of cigarettes a day but is unwilling to consider stopping at this time. At a recent visit, you obtained a lipid profile which revealed an LDL=140 with a normal HDL. This is consistent with a previous measurement made one year prior.

The best strategy for the next phase of management for this woman is:

  1. Begin an HMGCoA Reductase Inhibitor
  2. Begin Cholestyramine
  3. Recommend adherence to a dietary regimen
  4. Reassure the patient that her cholesterol is acceptable
  5. Recommend one glass of wine per day

Explanation


Question #36

A 77-year-old woman presents to the emergency room with sudden onset of severe chest pain radiating to her back just a few minutes after lifting a carton of books. Her past medical history is noteworthy for chronic hypertension and mild obesity. Her only medications include a daily aspirin and a thiazide diuretic, both of which she infrequently takes. On examination she is anxious and in severe pain. Her heart rate is 89/min and her blood pressure is 175/105 mm Hg. On examination her chest, heart, abdomen and extremities are normal. There is no point of tenderness over the chest or back. All pulses are full and bowel sounds are normal.

Her Hgb=11, BUN=18 mg/dL, creatinine=1.1 mg/dL.

Two EKG's are performed 10 minutes apart and both look like this:

She is given sublingual nitroglycerin with a decrease in blood pressure to 150/90 mm Hg and her heart rate=90. After the nitroglycerin she states her chest pain is still intense and is rated a 9 on a scale of 1-10 (1 = minimal, 10 = worst pain in my life).

You then get a chest x-ray:

Which one of the following is the most appropriate next step in managing this patient?

  1. Lower the blood pressure urgently using intravenous medications
  2. Do a transthoracic echocardiography
  3. Call a cardiovascular surgeon
  4. Obtain a series of radiographs of the spine to rule out ruptured vertebral disc
  5. Do an abdominal ultrasonagraphy immediately to exclude aortic aneurysm with rupture

Laboratory studies reveal a Hgb=11 g/dL, WBC=1.1, Platelets=30,000. All other chemistries, liver function tests, urinanalysis and chest x-ray are within normal limits. Blood cultures are obtained.

Which of the following is the most appropriate intervention at this time?

  1. Parenteral acyclovir and ceftazidime
  2. Granulocyte colony-stimulating factor (G-CSF)
  3. Platelet transfusion
  4. All of the above

Explanation


Question #38

  3. periekg

  4. repolariz

  5. repolariz2

Explanation
