A. Gravity pulls on air as well as everything else. The closer to the earth you are the more the air is compressed by gravity and the higher the air pressure as you ascend the pressure falls
B. There is a leak in the dropper somewhere the vacuum created by squeezing the bulb before putting it into the medicine holds the fluid in place if you lose vacuum the fluid flows out.

Pressure decreases at higher altitudes because there is less atmosphere above you to cause the pressure.

Yes indeed, gravity does act on air just like everything else. Also, At the earth's suface, we are at the "bottom" of the air column and have the weight of all that air over us causing pressure. As you move up in the column (i.e. away from the earth's surface) then you have less air mass weighing down on you causing lower pressure.
