Final Exam NUR 113
Normal range for Calcium - 8.5-10.5 mg/dL
Numbness, tetany, Chvostek + Trousseau's, seizures, mental status changes, dyspnea are the
manifestations of this electrolyte imbalance (hypo what?) Commonly caused by hypoparathyroidism,
malabsorption, pancreatitis, alkalosis, vit d deficiency, Mag deficiency, alcohol abuse.
Complications include: osteoporosis, seizures, laryngospasms - hypocalcemia
IV calcium gluconate and Vit D therapy (either with dietary intake or supplements) are
recommended for this electrolyte imbalance: - hypocalcemia
Muscular weakness, constipation, anorexia, nausea +vomiting, polyuria, polydipsia, lethargy, deep
bone pain, flank pain, CA stones, hypertension are the clinical manifestations of this electrolyte
imbalance? (Hyper what?)
Common causes are hyperparathyroidism, malignant tumors, immobilization, overuse of thiazide
diuretics, Vit D and A intoxication.
Complications include cardiac arrest, coma, death. - hypercalcemia
Treatment for this electrolyte imbalance would include IV admin of 0.9% Sodium chl, IV phosphate,
calcitonin hormone replacement. - hypercalcemia
These two electrolytes are regulated by parathyroid hormone - calcium and phosphate
These two electrolytes are inverted (IE being hypo they have fast S/S and being hyper they are low
and slow) - CA and Mag
This electrolyte is a major component of bone and teeth. Plays a major role in transmitting nerve
impulses and helps regulate muscle contraction and relaxation. Plays a role in blood coagulation as
well. - Calcium
Normal range for sodium - 135-145 mEq/L
, Poor skin tugor, dry mucosa, headache, decreases saliva, orthostatic hypotension, nausea, vomiting,
abdominal cramping, altered mental status, coma are all clinical manifestations of this electrolyte
imbalance (hypo what?)
Causes: fluid overload, exercise, excessive fluid intake before exercise, prolonged sweating, diuretic
use, loss of GI fluid, rental disease, adrenal insuff, hyperglycemia, heart failure.
Complications: increased intracranial pressure, lethargy, confusion, muscle twitching, focal
weakness, seizures, death. - hyponatremia
Treatment for this imbalance would be Na by mouth, lactated ringers or isotonic solution, water
restriction. - hyponatremia
thirst, increased body temp, swollen tongue, sticky mucus membranes, hallucinations, lethargy,
restlessness, irritability, pulmonary edema, seizures, twitching, nausea, vomiting, high pulse and BP
are clinical manifestations of this electrolyte imbalance? (hyper what?)
Causes: fluid deprivation, watery diarrhea, hypertonic enteral feedings, burns, diabetes insipidus,
intake of sea water, heatstroke, diaphoresis, excess cortico steroids, NA bicard, NA cl intake.
Complications: cerebral edema, seizure, coma, death - hypernatremia
Treatment for this imbalance includes: gradual lowering of NA levels by infusion of hypotonic
solution (0.45%) or D5W. - Hypernatremia
This electrolyte plays a role in controlling water distribution throughout body. Regulated by thirst,
RAAS, and ADH. Establishes the electrochemical state necessary for muscle contraction and
transmission of nerve impulses. - sodium
Normal range for magnesium - 1.3-2.1 mEq/L
(I have 1.8-2.6 per the textbook)
This electrolyte plays a major role in neuromuscular function. Activator for many intracellular
enzyme systems. Plays a role in both carb and protein metabolism. Can effect muscle cells,
irritability, or contractibility. High threshold for nerve fibers. Produces vasodilation and lowers
peripheral resistance. - magnesium
apathy, depressed mood, extreme agitation, +Trousseaus and Chvostek's, insomnia, vomiting, high
BP and increased deep tendon reflexes are s/s of this electrolyte imbalance? (hypo what?)
