Amount needed to replace fluid loss (from v/d)

35

What are some medical conditions that cause fluid imbalance?

Loss of protein

Endocrine disease

42

Sensible water loss

10-20 cc/lb/day

Urine

43

Insensible water loss

10 cc/lb/day

What are the major electrolytes of intracellular fluid?

Potassium, magnesium, phosphorus

46

What is the most abundant electrolyte?

Sodium

47

What primarily influences water distribution?

Sodium

48

What is a clinical sign of sodium imbalances?

Primarily neurological problems

49

What is hyponatremia?

Low Sodium Levels

50

What is hypernatremia?

High Sodium Levels

51

What is the dominant intracellular ion?

Potassium

52

What does potassium provide for the body?

It maintains osmotic pressure and cell metabolism and is responsible for the electical potentials in the muscles and nerves

58

What laboratory tests are used to determine fluid therapy needs?

Chemical profiles

PCV/TP

Urine specific gravity

59

Choice of fluids is based on what?

Severity of dehydration

Composition of fluids lost

Abnormality requiring correction

60

Crystalloid Fluids

What are they, what do they do?

Contain small solute particles which can pass through membranes

These fluids move into all body compartments
