2 >>Which of the following findings probably would be present in a patient who sustained recurrent pulmonary emboli? ?

3 >>True statements regarding the effect of alcohol on the heart include which of the following? ?

4 >>True statements regarding cardiac neoplasms include ?

5 >>A 65-year-old man with a history of multiple prior myocardial infarctions and episodes of congestive heart failure presents to the emergency room with sustained ventricular tachycardia (VT). His blood pressure is stable and he is mentating well. Administration of which of the following antiarrhythmic agents would be most appropriate? ?

6 >>The rhythm of the patient in VII-93 converts to normal sinus after the administration of the above agent. Unfortunately, in spite of continued administration the patient develops several other episodes of sustained VT. The most recent episode is poorly tolerated with the development of significant hypotension requiring electrical cardioversion. An electrophysiologic study fails to reveal an inducible VT/VF rhythm. Which of the following treatment recommendations would be associated with the highest overall survival? ?

7 >>Which of the following statements regarding exercise and cardiovascular morbidity is true? ?

8 >>A 70-year-old woman presents with blurring of vision in the left eye since waking earlier in the morning. She reports 2 months of fevers, sweats, anorexia, and a 4.5-kg (10-lb) weight loss. She also reports increasingly severe left temporal headaches over the same time period. Her physical examination reveals scalp tenderness over the left temporal region. Her laboratories reveal a normochromic, normocytic anemia, mildly elevated alkaline phosphatase, and an erythrocyte sedimentation rate of 92. Appropriate action includes ?

9 >>Which of the following statements concerning acute rheumatic fever is true? ?

10 >>You are asked to evaluate a 65-year-old man in the emergency room complaining of the acute onset of chest pain. During your evaluation the patient becomes unresponsive and is pulseless. A cardiac monitor reveals ventricular fibrillation. What would be the most appropriate sequence of events? ?

11 >>The patient in Question eventually develops a sinus rhythm with a stable blood pressure. He is transferred to the intensive care unit. It is discovered that the etiology of his ventricular fibrillation is most likely associated with a large anterior wall and myocardial infarction. During his postinfarction recovery phase, the patient undergoes a percutaneous coronary angioplasty with a stent placement; he quickly stabilizes. The patient has no further chest pain and no further arrhythmias during his hospitalization. Which of the following would be the most appropriate management decision with respect to his arrhythmia? ?

12 >>A woman who has rheumatoid arthritis suddenly develops pain and swelling in the right calf. The most likely diagnosis is ?

13 >>A young man is brought to the emergency department after having been submerged for a prolonged period in a nearby pond. Cardiopulmonary resuscitation was performed at the scene. The patient is being ventilated by mask and bag upon arrival in the emergency department. A brief examination reveals that the patient has no obvious sites of trauma and is conscious but not communicative. His blood pressure is 90/60, pulse is 120, temperature is 36
C (96.8
F), and respiratory rate is 30. Cardiac rhythm reveals sinus tachycardia. Pulse oximetry reveals oxygen saturation of 83%. Which of the following is the best method to reverse the patient’s apparent hypoxemia? ?

14 >>A 63-year-old man has pneumococcal pneumonia with extensive air-space consolidation in the left upper and left lower lobes. He complains of extreme shortness of breath when positioned with his left side down. An arterial blood sample drawn in this position shows a PO2 of 6.2 kPa (46 mmHg); 10 min earlier, an arterial blood sample drawn while his right side was dependent had revealed a P of 8.2 kPa (66 mmHg). The most likely explanation for the drop in PO2 when the man was lying on O2 his left side is ?

15 >>A 65-year-old man presents with progressive shortness of breath. Other than a history of heavy tobacco use, the patient has a benign past medical history. Breath sounds are absent two-thirds of the way up on the left side of the chest. Percussion of the left chest reveals less resonance than normal. While you place your hand on the left side of the chest and have the patient say “ninetynine,” no tingling is appreciated in the hand. The trachea appears to be deviated toward the left. Which of the following diagnoses is most likely ?

16 >>The best way to make a diagnosis of cystic fibrosis in a patient suspected of having this disorder is ?

17 >>A 21-year-old college student with no prior medical problems begins working as a laboratory technician. Copyright 2001 The McGraw-Hill Companies. Click Here for Terms of Use. He subsequently presents because of several recent episodes of shortness of breath, cough, fever, chills, and malaise. Each episode has lasted several days. The patient is seen during the recovery phase of an episode of this type; findings at physical examination are normal. Chest x-ray reveals several ill-defined, diffuse, patchy infiltrates. The laboratory evaluation is positive only for an increased erythrocyte sedimentation rate. Pulmonary function studies display reduced lung volumes. On further questioning, it is learned that these episodes begin on days when the patient is required to tend to experiments involving laboratory rats at the animal facility. What is the best treatment for this condition? ?

18 >>The primary pathophysiologic problem in idiopathic pulmonary fibrosis is believed to be ?

19 >>A 59-year-old man with a long-standing smoking history presents with persistent dyspnea. His FEV is 1.0 1 L/min, arterial blood gas reveals P of 60 mmHg, P O CO 2 2 of 40 mmHg, pH 7.45, and O saturation of 90%. He has 2 hyperlucent lungs on chest x-ray and decreased breath sounds on physical examination. The patient’s current medical regimen consists of theophylline (300 mg twice daily) and inhaled isoproterenol. The most important addition to the patient’s therapy would be ?

20 >>Although asthma is a heterogeneous disease, a given individual with asthma would be most likely to ?
