Dehydration (Fluid Electrolyte & Acid-Base Imbalance)

Question 1

dehydration

Answer 1

• volume deficit
• dec interstitial and intravascular fluids
• kidney not Fx properly / losing fluid:
• • draw from IS and cells
• • leads to dehydrated cells

Question 2

causes of dehydration

Answer 2

• inadequate intake of fluid
• 3rd spacing
• perspiration
• filtration in kidney
• vomiting/diarrhea

Question 3

Third Spacing

Answer 3

• there are 2 normal spaces for fluid in the ECF (interstitial space & intravascular space)
• 3rd space = transcellular space (abn)
• Ex: fluid in abd, bleeding into joint/body cavity, pleural space
• fluid difficult to get into 3rd space and difficult to get out of 3rd space
• fluid accumulates in transcellular space and is not readily exchanged
