Fluid Electrolyte 2 Flashcards
ECF=
And how much body fluids
Extracellular fluid
1/4-1/3
ICF =
And how much body fluid
Intracellular fluid
2/3-3/4 of the body fluids
There are two types of ECF (Extracellular fluid) what do they do
Intravacular fluids pick up o2 in lungs and nutrients in the gastrointestinal system to the interstitial fluid to cell where o2 and nutrients are used for by the cell
ICF deficit- hypovolemia
Dehydration
Decrease in fluid intake or marked increase in fluid output
What are the Causes and s/s of hypovolemia
Causes-Hyperventilation, diarrhea, vomiting,
S/S postural hypertension, weight loss, elevated temp, oliguria (report)
Weak rapid pulse
ECF excess- hypervolemia
Increase blood volume
Edema increase fluid interstitial compartments
Increase Extracellular osmolarity
What are the cause and s/s of hypervolemia
Cardiac insufficiency- decrease renal perfusion
Protein depletion- decrease plasma protein
Rapid administration of Iv saline
cirrhosis
Excessive water intake
S/S - peripheral edema, moist coracle lungs, wt gain, distend veins,
What is third spacing
Fluid where is shift to a cavity where it shouldn’t be
What is ascites
Fluid shifted into the abdomen
Hypokalemia occurs (causes) when
Lab value
Abbr
<3.5, k+ Poor intake of k+ Iv fluids for several days without dietary supplements of k+ Excessive use of diuretic Increase aldosterone secretion
s/s of Hypokalemia
Myocardial irritability ( arrhythmias, weak and irregular pulse)
Anorexia, vomiting, abdominal distinction, paralytic ileus
Profound muscle weakness
Postural hypotension
Hyperkalemia occurs when
Lab value
> 5.3
Supplements no longer needed
Renal failure , insulin insuffinencicy
Acidosis- k+ shift out of cells in exchange for h+
S/s of Hyperkalemia
> 8
GI hyperactivity
Confusion and irritability
Hypocalcemia occurs when lab value
< 4.3 Poor dietary intake of calcium and vitamin d defiency Loss via kidney Metabolic alkalosis Decrease in parathyroid hormone
S/s of hypocalcemia
Increase excitability Tetany - muscle spasm, sharp flexion of wrist and ankles Parathesias-numbness Anxiety, irritability Altered bleeding and clotting time
Hypercalcemia occurs when lab value
>10.5 Excessive intake of vitamin d Excessive intake of alkali compound (antacids ) Prolonged immobilizations Metastatic disease of bone Metabolic acidosis Parathyroid disease
S/s of Hypercalcemia
Deep bone pain
Sedative effects
High blood levels- kidney stones - shift of calcium from bones resulting in osteoporosis
Increased cardiac arrhythmias
High incidences of psychiatric disturbance
Hyponatremia occurs when
What is is
Lab value
Sign
Sodium, Na + , <135 Use of electrolyte free Iv solutin Fresh water drowning or increase h20 swallowing Ng tube irrigation with plain h20 Inadequate amount aldosterone H20 deprivation
Hyponatremia s/s
Feelings of apprehension , confusion, lethargy, headache
Muscle cramps
Postural hypotension
Hypernatremia occurs when
Lab value
>145 Ingest to much Na without water Salt water drowning Failure to drink water Excessive dieresis Ketoacidosis To much aldosterone
S/s hypernatremia
Edema, red flushed skin, dry sticky mucos, increased thirst, elevated temp, decrease urination, fatigue, restless
