Chest X-ray CT scan Brain scan Angiogramarrow_forwardMrs. C is a 50-year-old woman who presents with joint pain. She reports the pain has been present for about 2 years. The pain affects her hands and her wrists. She describes the pain as a “dull aching” and “a stiffness.” It is worse in the morning and improves over 2 to 3 hours.

(Use abbreviations for words that have them)arrow_forwardMr. H is a 52-year-old male who presents to the emergency department. His left leg is in a cast, and he states that 1 week ago he was in an automobile crash and broke his upper leg. Since that time, he has had difficulty “getting around” and has mostly been lying on the couch watching television. On the evening of admission he noticed a sudden onset of dyspnea and chest pain. He denies having orthopnea, cough, hemoptysis, or wheezing. He smoked two packs of cigarettes a day for 19 years but quit 3 years ago. The ABG analysis of Mr. H suggests uncompensated respiratory alkalosis with mild hypoxemia, with base excess of -1 in her arterial side, whereas -4 in her venous side. Part 1: Her actual arterial-venous oxygen content difference (Ca-vO2) is 5.31 mL/dL. (Normal range considered here is 3.5 to 5 mL/dL) Part 2: Patient's actual oxygen extraction ratio (O2ER) was 29%.
