Anatomy Lecture Exam IV Acid/Base/Electrolyte Balance

Your body is approximately [blank_start]70%[blank_end] water.

This type of body fluid is located within or inside the cell.

The two principal electrolytes of ICF are:

The body is made up of 2 body fluid compartments which are:

Interstitial fluid and plasma are examples of ECF

The two principle electrolytes of ECF are:

When giving a patient an IV the IV fluids go into the [blank_start]ECF[blank_end] and are [blank_start]isotonic[blank_end] so it will [blank_start]not[blank_end] shrink or swell the cells.

Water losses of which the individual is aware are called [blank_start]sensible[blank_end] water loss.

Water produced by cellular reactions is called [blank_start]metabolic[blank_end] water.

Which of the following examples are considered insensible water loss (may choose more than one)

put the following in order to give a mathematical formula [blank_start]pH[blank_end] = [blank_start]-log[blank_end] [blank_start][H+][blank_end]

A pH of 10 is [blank_start]1,000[blank_end] times more [blank_start]alkaline[blank_end] than a pH of 7.

Normal arterial blood pH is:

[blank_start]Respiratory alkalosis[blank_end] ------> hyperventilation [blank_start]Metabolic acidosis[blank_end] ---------> kidney failure, diabetes [blank_start]Respiratory acidosis[blank_end] -------> COPD [blank_start]Metabolic alkalosis[blank_end] --------> taking too many tums

What two ways do you regulate your pH?

[blank_start]Buffer[blank_end]s are two or more molecules which minimize pH change on addition of acid or base.

The buffer system is a weak acid minus the salt of that acid.

If hydrogen ion concentration goes up pH will go [blank_start]down[blank_end].

Acids are H+ [blank_start]acceptors[blank_end] and bases are H+ [blank_start]donors[blank_end].

What determines if an acid is strong or weak?

Buffers stop the change of pH an acid would have on a solution

Blood CO2 regulation is a balance is CO2 [blank_start]production[blank_end] and CO2 [blank_start]elimination[blank_end].

A reason blood CO2 levels would be high is:

Respiratory acidosis: ? [H+] ? pH ? CO2

Respiratory Alkalosis: ? [H+] ? pH ? CO2

Normal urine pH
