Lab Values
Lab Value 136-145 meq/L
NA+
Causes influx into the intracellular space
Hypotonic
Fluid Overload causes Na+ levels to_____ and dx with_____
Drop & Hyponatremia
Normal range pH
7.35 - 7.45
True/False: Hyperkalemic client should use salt substitute
False
Lab value 1.3 -2.1 meq/L
Mg+
The solution has same concentration of particles as the cell.
Isotonic
Client education for Dx of Hypernatremia (2)
1.) ^ po fluid intake
2.) limit Na+ intake
Excessive vomiting, ^ use antacids,
Alkalosis
Insensible fluid loss occurs
Lungs/respiration and skin/ perspiration
lab value 3.5 - 5.1 meq/L
K+
Causes H2O to move out of cell.
Hypertonic
These electrolytes have a reciprocal relationship and use a pump to cross the membrane
Na+ & K+
Hyperventilation causes loss of
CO2
Name three reasons the older client is at higher risk for fluid and electrolyte imbalance
Impaired thirst response
Decreased body fluid d/t decreased muscle mass & ^ adipose.
^ medications, ^ comorbidities, Decline in cardiac, renal and respiratory function
A value of 12meq/dl (normal 9-10.5 meq/L)
Hypercalcemia
The two extracellular compartments H2O can move to
Intravascular & Interstitial
What cardiac sx can Hyperkalemia cause
Cardiac dysrhythmia
pH 28 CO2 30 HCO3 22
Respiratory Acidosis
Specific Gravity 1.030 indicates
Concentrated urine/dehydration
A lab value of 130 meq/L (normal value 136-145meq/L)
Hyponatremia
Solutes moves from higher concentration to lower concentration
Diffusion
A positive Chvostek and or Trousseau's sign
Tetany Hypocalcemia
pH 47 CO2 36 HCO3 34
Metabolic Alkalosis
The best indicator of fluid status is
Daily weight
