A 44-year-old man with a 1-year history of angina pectoris
comes to the emergency department because of increasingly
severe chest pain during the past 2 days. He has had five
previous similar episodes, which required treatment with
increasing doses of nitroglycerin to resolve. His temperature is
37°C (98.6°F), pulse is 105/min , respirations are 16/min, and
blood pressure is 150/90 mm Hg. Cardiac examination shows an
S4. An ECG shows ST-segment depression in the precordial
leads. In addition to aspirin, heparin, and nitroglycerin, he is
given a dose of a monoclonal antibody against the platelet
lib/Illa receptor. This antibody will most likely prevent binding
of which of the following substances to platelets? - ANSWER-
Fibrinogen

examination. One year ago, she was diagnosed with a
pulmonary embolism. Two years ago, she delivered a female
stillborn at 23 weeks gestation. Physical examination today
shows no abnormalities. Laboratory studies show a platelet
count of 250,000/mm3, a prothrombin time within the reference
range, and an increased partial thromboplastin time. The
findings in this patient are most consistent with which of the
following conditions? - ANSWER-Antiphospholipid antibody

A 12-year-old African American girl is brought to the emergency
department by her mother because of a 6-hour history of fever
