All functioning cells, organ, blood or any other substance need to always be constant (in this case pH) and a slight change will lead to a loss of function. Fortunately, there are chemicals called buffers that act by maintaining comstant internal environment, and they work by absorbing excess hydrogen ions or releasing them depending on the acidity or alkalinity thus resisting a change in the chemical environment.

Answer:
b. invert the IV bag and squeeze the drip chamber.
Explanation:
The drip chamber is the place where we can see the fluid that is dripping into the tubing from the IV bag. It is at the drip chamber that the speed of the IV set up is measured by counting the number of drops per minute. It is expected that the drip chamber is always half full because if it is too full, it is impossible to count the drops. However, in a case where the drip chamber is too full, the EMT must invert the IV bag and squeeze the drip chamber to allow some of the liquid out, while not allowing any flow from the IV bag into the drip chamber.
