Fluid balance, electrolytes, and fluid replacement Flashcards
Fluid balance
assessment of the volume of water lost from the body and volume of water gained
Fluid Balance: Water gained
- Fluid and food in diet
- IV infusions
Fluid Balance: Water loss
- Urine
- evaporation from the skin
- sweat
- respiration
- feces
Assessment and recording of fluid balance is done by measuring?
what goes in (oral fluid, IV fluids) and what comes out (urine, blood loss, vomiting, diarrhea)
What is insensible loss and why is it important midwives are mindful of it?
Fluid loss that cannot be measured: sweating, evaporation from high temperature, respiration from exercise like labor
Conditions that contribute to fluid imbalance in maternity care:
- hypovolemic shock
- pre-e
- septic shock
- anaphylactic shock
- hyperglycemia
ABCDE for assessment of fluid and electrolyte status: A
Assess airway and note general impression. is she thirsty, dry mouth, cracked lips?
A woman with fluid overload may have
wheezing or excessive secretions
ABCDE for assessment of fluid and electrolyte status: B
assess respiratory rate and measure oxygen saturation
crackles, wheezing, and or pink frothy sputum and deteriorating oxygen saturation may indicate pulmonary edema
ABCDE for assessment of fluid and electrolyte status: C
Circulation: measure the VS: Pulse, BP, and temp
with fluid depletion, signs of compensatory mechanisms may become evident: HR increases, and as fluid depletion continues, BP will drop although this will be a late sign in a pg woman.
ABCDE for assessment of fluid and electrolyte status: D
manifestations of hypovolemic shock and electrolyte imbalance will affect neurological function. dizziness and anxiety may occur. reflexes may be affected. rising urea can affect level of consciousness
ABCDE for assessment of fluid and electrolyte status: E
Exposure: edema, skin turgor, acute weight changes, and blood loss
Why is IV fluid administration used for fluid replacement
will improve the volume of fluid within the intravascular compartment (Blood vessels) and this in turn has an impact on fluid in the extravascular compartment (Interstitial space and cells)
Why is it important to insert an iv as soon as problems arise or waiting for medical assistance?
peripheral shutdown will increase as I’ll health progresses, making it increasingly difficult to gain IV access
