A teenager is admitted to the medical unit with a significant loss of extracellular fluid (ECF) volume following several sports practices in the extreme heat
Which sign or symptom is most representative of an early significant loss of extracellular fluid volume that the nurse needs to monitor in the client? A) High urine output
B) Congestive heart failure
C) Hypotension
D) Coma
C
Feedback:
The volume of ECF is the most important regulated aspect of body fluid balance. Without adequate ECF, the body cannot maintain normal blood pressure. A significant loss of ECF volume can drop blood pressure to a life-threatening point where cells can no longer function, due to a lack of oxygen and nutrients. Untreated, this can progress to a coma. Too much ECF can place a person in a fluid overload state, leading to high blood pressure and risk for conditions such as congestive heart failure.
