This is the dynamic process in which the body maintains balance by constantly adjusting internal and external stimuli
Homeostasis
Electrolytes are a substance that will disassociate into THIS when dissolved in water
IONS
Symptoms of this include anorexia, n/v, headache, confusion, dry skin, edema
HYPONATREMIA
This is an intervention for a patient with hyponatremia
-Assess for s/s nausea and malaise
-Monitor neuro status
-Restrict water intake
-Administer meds/fluids as ordered (sodium tabs, sodium-containing IV fluids
-Etc
metabolic alkalosis
r) loss of hydrogen ions (think stomach acid)
These two systems are involved in providing "feedback" to help with regulation
NERVOUS SYSTEM and ENDOCRINE SYSTEM
Nervous system uses NERVES
Endocrine system uses HORMONES
INTRACELLULAR ELECTROLYTES
Positive Chvostek and Trousseau Signs indicate this
HYPOcalcemia- other signs are numbness, tingling, seizures, irritability, bronchospasm
(Chvostek- facial twitch when tapping on nerve, Trousseau-spasm/tetany with BP cuff inflated)
This is a nursing intervention for excess fluid volume.
Monitor VS and possible CVP
Daily weights
Assess for vein distention, edema, dyspnea
Monitor I&O
Assess edema
Replace electrolytes
Administer diuretics as ordered
Pt with RR of 8 is expected to have this imbalance
Increased CO2, possible respiratory acidosis
These are the two main "compartments" that hold body fluids
Intracellular fluid
stabilizing agent for parts of cell, cell shape, assist with nutrient transport across, into, and out of cell
Extracellular fluid
interstitial tissue fluid and intravascular fluid
Sodium, chloride, calcium, bicarbonate
EXTRACELLULAR ELECTROLYTES
Symptoms are chest pain, nystagmus, paresthesias, bone pain and tenderness, tissue hypoxia
HYPOphosphatemia
Normal range for pH
7.35-7.45
Decreased CO2, respiratory alkalosis
The term for daily intake matching daily output
EUVOLEMIA
Muscle cramps, palpitations, weakness may mean THIS electrolyte is low
POTASSIUM
Signs are constipation, muscle weakness, hypoactive DTRs, flank pain
HYPERcalcemia
CMP
BMP- BUN and creatinine, glucose, carbon dioxide, calcium, sodium, potassium, chloride
These are common causes of metabolic acidosis.
Lactic acidosis, ketoacidosis (increased production, such as in sepsis or DKA)
Renal failure (reduced H+ excretion)
Diarrhea (excessive bicarb loss)
The excess accumulation of fluid in the interstitial tissue spaces
EDEMA
aka "third spacing"
Edema is the result of a disruption of the filtration and osmotic forces of the body's circulating fluids
Low HR, Low BP, difficult/slow breathing
Signs of HIGH magnesium
HYPERnatremia
Fever, chills, altered BP, respiratory difficulty, pain in chest/flank, n/v, rash are all signs of THIS
Blood transfusion reaction
Treatment: Stop transfusion, keep IV open with saline, given benadryl/possibly steroids, KEEP THE BLOOD to send back to lab, consult MD for lab testing orders
These two organs work together to maintain acid-base balance
Lungs
Kidneys
