Question

A 25-year-old female was hospitalized because of increasing shortness of breath and development of a cough with blood-tinged sputum. Except for asthmatic attacks precipitated by various environmental allergies, she had always been in good health. One week before hospitalization, this patient had developed what she called "a cold" characterized by a mild sore throat and nonproductive cough, malaise, and a generalized dull headache. Three days prior to hospitalization the patient experienced a 15 minute severe shaking chill. After this episode the cough became worse and more productive of sputum (bloody looking). A physical examination revealed an oral temperature of 104 F, pulse 124 per minute, and blood pressure 112/70. Respirations were 36 per minute; each expiration was accompanied by a "grunt". The chest was hyper-resonant to percussion and filled with inspiratory and expiratory wheezes. Fine crackling rales were heard on inspiration over the lower anterior chest just to the right of the sternum. The patient had a total leukocyte count of 12,500 per cubic millimeter, with 71% segmented neutrophils, 17% band cells, 11% lymphocytes and 1% eosinophils. Urine was found to have a pH of 5.5 and gave a 1+ reaction for protein. A freshly collected sputum was gram stained and revealed numerous gram positive cocci and rods. Chest X ray revealed a distinct infiltrate involving the right middle lobe. The Quellung reaction was positive. The patient's physician ordered procaine penicillin, 600,000 units via the intramuscular route every 6 hours and intermittent positive pressure breathing treatments to relieve the bronchospasm and allow the patient to rest more comfortably.
