F&E and Respiratory Flashcards

1
Q

What is the difference between dehydration and volume depletion?

A

Dehydration: Hypernatremia with water loss (losing water as sodium rises)

Volume depletion: Isotonic loss - water and sodium are lost equally

Q

What is the difference between the distribution of fluids in children under 5 and those over 5?

A

Under 5: More volume in the extracellular so unstable and can shift rapidly with changes in either metabolic or environmental facts causing F&E imbalances

Over 5: More volume in intracellular so their fluid is more stable

Q

How do immature kidneys put a child at increased risk of F&E imbalances?
