Electrolytes & The Body
Amanda Cangialosi
NUR 311 - Professor Evinrude




Normal Values: 135 - 145 mEq/L
Mg 2+
Ca 2+
Balance is primarily regulated by the kidneys
Excreted through urine, sweat, and feces
Absorbed from food in GI tract
Controls water distribution between ECF and ICF
Determines osmolality of extracellular fluids
Important component to the process of nerve impulse transmission
Important in the balance of acids and bases in the body
May be caused by water loss or sodium gain
IV sodium intake
Inadequate water intake
Insensible water loss (fever, diarrhea)
Diabetes Insipidus
Cushing Syndrome
Signs & Symptoms are a result of cell shrinkage
Easily activated neurons
Nursing Interventions treat underlying cause
Use hypotonic IV solution to replenish fluids
Limit dietary sodium intake
Decrease sodium levels gradually to avoid cerebral edema
Promote sodium excretion with use of diuretics
Clients at Risk
Patients receiving tube feedings
Patients at risk for developing fevers
Patients suffering from diarrhea and/or vomitting
Patients with diseases such as Diabetes Insipidus, Cushings Syndrome, and Diabetes Mellitus
Patients who are unable to access water
Poverty, inability to ambulate, cognitive impairment
Likely Physician Orders
Water Replacement:
Increased oral fluid intake
IV 5% Dextrose in water
IV Hypotonic Saline
Sodium Reduction
Dietary sodium intake restriction
Nursing Assessment
Observe extremities
Twitching, seizures, agitation
Edema may be present with increased ECF volume
Psychological assessment
Restlessness, agitation, lethargy
Cardiac assessment
Blood pressure & central venous pressure may be increased with elevated ECF volume
Blood pressure and central venous pressure may be decreased with decreased ECF volume
Hypotension may be present with decreased ECF volume
Skin assessment
Mucus membranes may be dry with decreased ECF volume
Skin may be flushed with increased ECF volume
Symptoms result from cellular swelling as water moves from ECF to ICF in order to attempt to compensate for the sodium imbalance
The first symptoms are noted in the Central Nervous System as brain cells begin to swell
Irritability, confusion, dizziness, personality changes
Several symptoms vary according to ECF volume changes
Increased ECF volume: blood pressure and central venous pressure will increase, weight gain, headache, and abdominal cramps may occur
Decreased ECF volume: blood pressure and central venous pressure will decrease, cold/clammy skin, tachycardia, nausea, vomiting, diarrhea and dry mucus membranes may occur
Life threatening symptoms include seizures and coma
Overall loss of fluid
Wound drainage
Water excess (dilutes ECF)
Overuse of hypotonic IV fluid
Excessive thirst (leading to excessive water intake)
May occur with disease processes such as SIADH and hypoaldosteronism
Clients at Risk
Patients with problems causing polydipsia
Such as SIADH
Patients with disease processes such as heart failure and liver failure
Patients who have suffered an overall fluid loss
Trauma resulting in large wounds and/or burns
Patients who do not have access to adequate foods
Poverty, immobility, cognitive deficiencies
Treatment depends on underlying cause
Water excess
fluid intake is restricted
Fluid loss
IV solutions may be used to replenish sodium and fluids
Hypertonic solutions will do this
Drugs may be used to block ADH - thus stopping the body from retaining water and excreting sodium
Specific drugs will be used to treat and prevent hyponatremia associated with chronic diseases
Likely Physician Orders
The physician may order several different interventions depending on the underlying cause of the sodium imbalance
With water excess, the physician will most likely order a fluid restriction on the patient's diet
In cases of severe fluid loss, the physician will likely order a 3% Normal Saline IV solution to replenish fluids and sodium
A vasopressin drug such as Vaprisol may be ordered to inhibit ADH activity
In the case of a chornic disease, (i.e. heart failure, liver failure, SIADH) a drug such as Samsca will most likely be ordered
Nursing Assessment
Observe neurological system to assess CNS function - indicative of cellular swelling in brain
is patient confused, irritable, and/or apprehensive?
has personality changed?
Are muscle spasms, tremors, cramps, or seizures present?
Observe cardiac system - indicative of ECF volume excess or deficit
Is patient hypo or hypertensive?
Is central venous pressure too high/low?
Is jugular vein filling normally?
Is pulse thready?
Is pulse too fast or too slow?
Observe skin - indicative of fluid loss or water excess
Are mucus membranes dry?
Is skin cold and/or clammy?
Has abnormal weight gain occured?
Is edema present?
Geriatric Considerations
Inability to access necessary foods containing sodium
Inability to access water, resulting in dehydration
Cognitive deficiencies
Inability to feed oneself necessary foods containing sodium or drink enough water
Heart and/or liver failure
geriatric patients are more likely to suffer from bodily systems not working properly, such as the heart and liver
Insufficient thirst mechanism
with age the thirst mechanism may not work properly, causing a geriatric patient to drink too much or too little water
Insufficient hunger mechanism
with age, bodily mechanisms triggering one to feel hungry may be diminished, causing one to eat less, leading to malnutrition
The following problems are concerns for elderly patients, but are not considered normal findings!
Normal values: 3.5 - 5.0 mEq/L
Main cation in the intracellular fluid!
Main cation of the extracellular fluid!
Plays an important role in the sodium-potassium pump
Balances of K+ are directly responsible for resting potential of nerve and muscle cells
Intracellular osmolality depends on potassium
Acid-base balance is affected by potassium balance
Mainly obtained through dietary means
Potassium is mainly excreted by renal system
Balance between extracellular and intracellular potassium concentration is crucial to potassium working correctly in the body
Many symptoms are a result of increased cellular excitability
Muscular: weakness in legs, abdominal cramping
Affect: Anxious, irritable
Cardiac: Irregular pulse, Cardiac arrest
GI: diarrhea
ECG Changes:
Peaked T Wave
Loss of P wave
Widened QRS
Ventricular fibrillation or standstill

Excessive potassium intake
Parenteral administration
Use of drugs containing potassium
Over-consumption of foods containing salt substitutes
Insufficient renal excretion of potassium
Kidney failure or disease
Use of diuretics that spare potassium (i.e. spironolactone)
Use of ACE Inhibitors (i.e. lisinopril)
Aldosterone deficiency
Potassium shift from intracellular to extracellular fluid
Metabolic Acidosis
Massive tissue/cell destruction
Dietary potassium intake restriction
Increased elimination of potassium
Shift potassium back into intracellular fluid
Reverse membrane excitability

Likely Physician Orders
Potassium Supplements
Either IV or Oral
IV is only used in severe cases
Dietary intake orders
Salt substitutes can be used to raise potassium
If patient is taking potassium-losing diuretics
Dietary potassium must be increased
If patient is taking diuretics and is suffering from hypokalemia
Physician may choose to change orders to a potassium-sparing diuretic
Nursing Assessment
Neurological Assessment
Observe affect: Is patient fatigued?
Is patient experiencing paresthesias or decreased reflexes?
Muscular Assessment
Is patient experiencing muscle weakness?
Is patient experiencing muscular cramping?
Is patient experiencing flabby muscles?
GI Assessment
Is patient experiencing nausea and/or vomiting?
GU Assessment
Monitor I/O: Is patient urinating excessively?
Cardiac Assessment

Take heart rate: is it fast and/or irregular?
Observe ECG:
Look at T wave: is it flattened?
Look for presence of U wave
Look at ST segment: is it depressed?

Geriatric Considerations
Elderly patients are more likely to experience hypokalemia
Many elderly patients take diuretics and are thus at risk to develop a potassium imbalance
Elderly patients are more likely than other populations to experience GI infections and diarrhea, making them more prone to develop a potassium imbalance
Elderly patients are at a higher risk than other populations for malnutrition, making them more at risk to develop hypokalemia
1.5 - 2.5 mEq/L
Second most abundant intracellular cation!
Much magnesium is found in bone
Magnesium is important in the process of metabolizing carbohydrates and protein
Magnesium is absorbed by the GI tract
Magnesium is excreted by the kidneys
Magnesium imbalances can very easily be mistaken for calcium imbalances!
Magnesium is essential for the cardiac system to function normally, which makes imbalances dangerous and potentially life threatening
Excessive magnesium intake
Renal insufficiency
Renal failure
Magnesium sulfate supplementation
as used to treat pregnant women with eclampsia
Addison disease
Lithium therapy
Excessive vitamin D intake
Affect: Lethargic, drowsy
Diminished deep tendon reflex
Nausea and vomiting
Neuromuscular symptoms are the most common
Deep tendon reflex attenuation is one of the earliest symptoms
High concentrations can lead to somnolence, bradycardia, hypotension, heart block, and cardiac arrest
Clients at Risk
Patients with renal insufficiency or renal failure
Pregnant women with eclampsia
Patients with hypocalcemia
Patients who are prescribed or who abuse laxatives
Premature babies
Most treatment is focused on prevention
If kidneys do not function properly, do not take
Renal excretion may be increased
IV administration of calcium chloride or calcium gluconate opposes the effects of magnesium on cardiac muscle
If a patient's kidneys are not working properly, dialysis may be needed to remove magnesium
Nursing Assessment
Neurological Assessment
Are CNS functions depressed?
Is affect drowsy, lethargic, or somnolent?
Muscular Assessment
Are deep tendon reflexes present?
GI Assessment
Is patient nauseous and/or vomiting?
Cardiac Assessment
Assess heart rate: is it fast?
Assess blood pressure: is it low?
Beware that high concentrations can lead to cardiac arrest
Are there ECG changes?
Respiratory Assessment
Are respirations decreased?
Beware that apnea may develop with high concentrations
Likely Physician Orders
A physician dealing with a patient with chronic kidney disease will focus on prevention of hypermagnesmia by teaching the patient about the risks of toxicity and what sort of drugs and foods are to be avoided
In emergency situations, a physician will order IV calcium chloride or calcium gluconate in order to oppose the effects of excess magnesium on the heart - which can lead to cardiac arrest if left untreated
The doctor may promote increased fluid intake in order to promote urinary excretion of magnesium in patients with functioning kidneys
In patients with impaired renal function, dialysis will most likely be needed in order to remove magnesium as the kidneys will be unable to excrete it
Malnourishment is one major cause of hypomagnesemia
This may be a result of fasting or starvation
Chronic alcoholism may contribute to malnourishment
Parenteral nutrition without proper magnesium supplementation
Losses are generally gastrointestinal or renal
GI losses include diarrhea, vomiting, and impaired absorption ability of GI tract
Renal loses may be caused by diabetes mellitus (resulting in osmotic diuresis) and use of diuretics
Hyperactive deep tendon reflexes
Cardiac dysrhythmias
Resemblance to hypocalcemia
Oral magnesium supplements
Increased dietary intake of magnesium
Magnesium sulfate may be administered by IV or IM routes in critical situations
Medication to relieve symptoms while magnesium levels are brought back up to normal ranges
Clients at Risk
Patients with anorexia and/or bulimia
Patients who are fasting or do not have access to adequate foods
Patients receiving parenteral nutrition
Patients taking diuretics
Patients with hyperaldosteronism
Patients with celiac disease or irritable bowel syndrome
Patients taking aminoglycocide antibiotics
Patients recovering from acute renal failure
Patients with polyuria
Likely Physician Orders
Oral magnesium supplements
Increased dietary intake of magnesium
Doctor will recommend foods such as green vegetables, bananas, nuts, and oranges
In severe case scenerios, the doctor will likely order parenteral IV or IM magnesium sulfate to be administered
the doctor and nurse should be careful with administration of magnesium in this manner, as administering too rapidly can lead to cardiac and/or respiratory arrest
Nursing Assessment
Neurological assessment
Assess cognitive status: is patient confused or delirious?
Is the patient experiencing any numbness?
Beware that this patient is at risk for seizures and coma
Muscular assessment
Are deep tendon reflexes hyperactive?
Is the patient experiencing muscle cramping and/or weakness?
Is the patient experiencing tremors?
Cardiac assessment
Assess heart rate: is it irregular?
Geriatric Considerations
The geriatric population is at a higher risk to experience imbalances
Diuretic use is more common in older adults, and may cause magnesium imbalances through urinary loss
The elderly population is more likely to suffer from renal insufficiency, making the susceptible to magnesium imbalances as kidenys may be unable to properly excrete magnesium
Elderly adults may be more likely to suffer from absorption problems in the bowel due to disorders such as IBS
Elderly adults are more likely to suffer from malnourishment than other populations, making them susceptible to magnesium deficiencies
8.6 - 10.2 mg/dL
Calcium is mainly obtained through dietary means
Calcium movement must be regulated from bones to serum and vise versa to maintain normal serum levels
The ionized form of calcium is the active form
Total serum calcium levels reflect three different forms of calcium found in serum:
Bound to albumin
Complexed with phosphate, citrate, or carbonate
99% of calcium is stored in the skeletal system!
Breast cancer
Lung cancer
multiple myeloma
Prolonged immobilization
Excessive vitamin D ingestion
Use of thiazide diuretics

GI: Nausea, vomiting, reduced apatite
GU: nephrolithiasis, polyuria
Musculoskeletal: Depressed reflexes, overall weakness, bone pain, fractures
Cardiac: Shortened ST segment, shortened QT interval, dysrhythmias
Promote the excretion of calcium in urine
Loop diuretics
Increased water intake
Patient may be hydrated with saline infusions

The doctor may inform the nurse to promote increased fluid intake in order to support renal excretion of calcium
The doctor may order the patient to increase water intake to 3,000 - 4,000 mL daily
The doctor may order synthetic calcitonin in cases of very high serum concentration of calcium
Mithracin may be ordered to to inhibit bone resorption
If hypercalcemia is a result of malignancy, the doctor may order a drug such as Aredia to inhibit osteoclasts from breaking down bones

Likely Physician Orders
The physical may order either oral or IV calcium supplements if deficiency is serious
The doctor will not order IM calcium because it damages tissues
The doctor will order a diet with many calcium rich foods
The doctor may order vitamin D supplements to aid in calcium absorption
If patients are unable to obtain calcium through dietary means, the doctor will likely order a supplement to be taken long term

Assess for muscular cramping
Assess for tetany
Cardiac Assessment
Asses ECG: Look for ST segment elonglation, prolonged QT intraval
Take heart rate: is it faster than normal?
Geriatric Considerations
Geriatric populations are more likely to experience calcium imbalances
Hypercalcemia is often caused by malignancies, which become much more common with age
Hypercalcemia is also associated with immobility and increased osteoclast activity, which are both prevalent issues in many older adults
Hypocalcemia and hypercalcemia can both result from diuretic use, which is common in elderly adults
Elderly adults are more likely to experience kidney disease than other populations, putting them at risk for hypocalcemia

Phosphorus is the primary anion in the ICF!
2.4 - 4.4 mg/dL
Phosphorus plays important roles in the body such as muscle function, RBC function, and nervous system function
Phosphorus is a prevalant part of the acid-base buffer system
Phosphorus is involved in the production of ATP
Phosphorus is involved in the metabolism of carbs, proteins, and fats
Phosphorus is mainly excreted by the kidneys
Phosphorus and calcium are inversely related in serum values
Renal failure
Kidneys are unable to excrete phosphate
Excessive phosphate ingestion
Milk, laxatives
Excessive vitamin D ingestion
Calcified deposits in soft tissue
joints, arteries, skin, kidneys, corneas
Muscle problems such as tetany
Neuromuscular irritability
Underlying cause is treated
Dietary intake of phosphate should be restricted
Increasing fluid intake may promote renal excretion of excess phosphorus
Hypocalcemic conditions should be corrected in order to allow for PTH to act on kidneys and cause phosphorus excretion
Calcium supplements & Phosphate binding agents may be used in the case of renal failure/insufficiency
Clients at Risk
Patients with renal failure
Patients with malignancies
chemotherapeutic agents contribute to hyperphosphatemia
Patients receiving enemas
some enemas contain phosphorus
Patients ingesting large amounts of vitamin D
Vitamin D enhances phosphorus absorption in GI tract
Patients with hypoparathyroidism
Likely Physician Orders
The physician will attempt to treat the underlying cause of hyperphosphatemia
The physician will most likely order a diet low in phosphorus
The physician may order increased fluid intake in order to assist with renal excretion of phosphate
The physician will most likely attempt to correct hypocalcemia if it is present, as hypocalcemia causes kidneys to retain phosphorus
If the physician is dealing with a patient with chronic renal failure, he may use calcium supplements and/or phosphate binding agents to prevent phosphate levels from elevating beyond normal limits
Nursing Assessment
Muscular Assessment
Is tetany present?
Skin Assessment
are there calcium-phosphate deposits present in skin/soft tissues?
Lab Assessment
Is hypocalcemia a current issue for this patient?
Mainly caused by malnourishment

Nursing Assessment
Neurological assesment:
Assess affect: confusion, loss of consciousness, coma
Muscular assessment
Assess muscles for weakness
Respiratory assessment

Cardiac assessment
Take heart rate - is it slow?
Assess stroke volume - is it decreased?
Likely Physician Orders
The doctor will attempt to treat the underlying cause of deficiency
Oral supplementation of phosphate will most likely be ordered
The doctor may order increased dietary intake of foods with phosphorus in them
In severe cases, the doctor will most likely order IV administration of sodium phosphate or potassium phosphate
Geriatric Considerations
Geriatric patients are more likely to suffer renal failure than other populations, increasing their likelihood of hyperphosphatemia
Geriatric patients are more likely to suffer malignancies than other populations, making them more likely to use chemotherapeutic agents that may increase phosphate levels
Geriatric patients who are immobile or who have lost their appetite may suffer from malnutrition - which can cause hypophosphatemia
Geriatric patients are more likely than other populations to suffer from malabsorption syndromes which can interfere with GI abosrption of phosphate
