There s hardly a disease process or medical
intervention that does not involve a threat or a
potential threat to a patient s fluid and electro-
lyte balance. Even patients who are only
mildly ill can rapidly develop critical imbal-
ances.
The nurse is the health-care worker who
most continually observes and evaluates pa-
tients progress. So the nurse is most logically
accountable for assessing and reporting real or
potential fluid and electrolyte disturbances.
Very minor changes in a patient s behavior
such as slight restlessness， twitching， or a
change in breathing patterns may be early
signs of imbalance. A knowledgeable nurse
can recognize these minor changes， report
them accurately， and effectively manage the
situation; frequently she can prevent serious
or even life-threatening problems.
This Skillbook will help you to build a foun-
dation of competence. It focuses on the
nurse s role in assessment， record-keeping，
and management of fluid and electrolyte dis-
turbances. And it gives real applications of
these complex and sometimes difficult-to-
grasp principles. This book begins with the
physiology of fluids and electrolytes in the
balanced state (homeostasis); continues with
definitions and tips for recognizing imbalance;
describes the function of the key electrolytes
