Pharmacology and the Nursing Process by Linda Lane Lilley: Practice Exam

Streptokinase is a medication used to dissolve blood clots, and hemothorax is a condition where blood accumulates in the pleural space of the lungs. The first recorded use of streptokinase to dissolve a clotted hemothorax was in 1947, making the correct answer A. The other options are incorrect because they are either too early or too late for the first recorded use of streptokinase in treating hemothorax. Option B is 1958, which is more than a decade later than the first recorded use. Option C is 1960, which is also after the first recorded use. Option D is 1933, which is earlier than the first recorded use.
