Answer to Question 1

A
Fibrinolytic agents such as streptokinase (Streptase), urokinase (Abbokinase), alteplase (Activase), and reteplase (Retavase) actually dissolve blood clots. These agents (commonly referred to as clot-busters) have proved beneficial in treating acute pulmonary embolism. Heparin is an anticoagulant, not a fibrinolytic. Vitamin K does affect clotting time but is not given therapeutically to break up an existing blood clot.

Answer to Question 2

B
Peptococci and B. fragilis are anaerobic microorganisms and may be present in the lower respiratory tract following aspiration.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
