Exam 1: Education, Fluids, Electroytes, Renal Failure, Acid Base Imbalances Flashcards
What are some risk factors for a fluid volume excess?
Excessive fluid replacement, kidney failure, heart failure, long term corticosteroid use, SIADH, psychiatric disorders with polydipsia, and water intoxication.
What are some risk factors for a fluid volume deficit?
Hemorrhage, vomiting, diarrhea, profuse salivation, fistulas, ileostomy, profuse sweating, burns, severe wounds, long term NPO status, diuretic therapy, GI suction, hyperventilation, diabetes insipidus, fever, coma, impaired motor func
What are some complications of a fluid volume excess?
CHF, pulmonary edema, skin breakdown, poor perfusion, coma, potential for injury, possibly seizures and multi organ system failure.
What are some complications of a fluid volume deficit?
Potential for injury, poor perfusion, seizures, coma, hypovolemic shock, multi system organ failure
What are some things a nurse should assess for a pt with a fluid imbalance?
Input and output, daily weight, medications, hx of renal or endocrine issues, LOC, vitals, muscle weakness or spasms, visual changes, headaches, skin, extremities, edema, pulses, cap refill, skin color and temp
What labs are a priority to look at for a fluid volume excess and what are the anticipated results?
Serum osmolality: decreased
CBC: decreased
BUN: decreased
Serum sodium: decreased
Urine specific gravity: decreased
REMEMBER: it’s decreased because it’s very diluted!
What labs are a priority for a fluid volume deficit and what are the anticipated results?
Serum osmolality: increased
CBC: increased
BUN: increased
Serum sodium: increased
Urine specific gravity: increased
REMEMBER: it’s increased because it’s very concentrated!
What are some potential assessment findings for a fluid volume excess?
Tachycardia, bounding pulse, hypertension, distended neck veins, weight gain, tachypnea, shallow respirations, shortness of breath, moist crackles in lungs, pitting edema, cool and clammy skin, altered LOC, headache, weakness
What are some potential assessment findings for a fluid volume deficit?
Weight loss, skin tenting, dry mucous membranes, weak thready pulse, orthostatic hypotension, lightheadedness, flat neck veins, oliguria, syncope, hypovolemic shock
What are some interventions that may be implemented for a fluid volume deficit?
Oral rehydration, isotonic IV solution (0.9% NaCl or LR), O2 for confusion, monitor I&Os, daily wt, monitor vitals and peripheral pulses, monitor LOC and mental status, and safety precautions.
If SEVERE: hypotonic IV solution (0.45% NaCl)
What are some interventions that may be implemented for a fluid volume excess?
Monitor vitals, pulses, edema, lung sounds, and I&Os, daily wt, Fowlers position, treat cause first then may use diuretics (furosemide and mannitol) restrict intake of water and sodium.
If SEVERE: hypertonic IV solution (D5W NaCl or D5W in LR)
What are some causes of hypercalcemia?
Bone destruction, bone disorders, hyperparathyroidism, decreased excretion from kidney disease, glucocorticoids, dehydration, immobilization, calcium or vitamin D overdose from supplements, acidosis, thiazide diuretics, and increased intake of calcium antacids.
What may be some causes of hypocalcemia?
Low intake, lactose intolerance, parathyroidism, pancreatitis, multiple blood transfusions, alkalosis, laxative abuse, malabsorption syndromes, kidney disease, vitamin D deficiency, low magnesium, alcoholism, diarrhea, loop diuretics, wound drainage, and immobility
What are some assessment findings a nurse might find with hypercalcemia?
Tachycardia, hypertension, bounding pulse, lethargy, weakness, confusion, decreased reflexes, n/v, bone pain, bone fractures, polyuria, and kidney stones.
What are some assessment findings a nurse may find with hypocalcemia?
Bradycardia, hypotension, weak peripheral pulses, tetany, positive chvoteks and trousseaus signs, dysphasia, fatigue, anxiety, depression, hyperreflexia, muscle spasms, and numbness and tingling of extremities and around mouth.
What are some priority nursing intervention and medications for hypercalcemia?
Find and treat underlying cause, hydrate with fluids, low calcium diet, increase wt bearing exercises, strain urine for kidney stones, assess, for flank pain, give furosemide to excrete through kidneys, give calcitonin to lower serum levels, give pamidronate to lower levels
What are some priority nursing interventions for hypocalcemia?
Find and treat underlying cause, increase intake of calcium and vitamin D, administer IV calcium gluconate, monitor ECG.
What are some foods that are rich in calcium?
Milk, yogurt, mozzarella, cheddar, collard greens, broccoli, kale, sardines, salmon, shrimp, beans, food fortified with calcium
What are some causes of hyperkalemia?
Acidosis, burns, injuries, infections, potassium sparing medications, high intake, medications high in K, renal failure, adrenal insufficiency, overuse of K salt substitute
What are some causes of hypokalemia?
Diarrhea, vomiting, inadequate intake, overuse of laxatives, low magnesium levels, excessive sweating, hydration with fluids w/o K, stress, alkalosis, wound drainage, potassium wasting diuretics, kidney disease, water intoxication, GI suction
What are some assessment findings a nurse may find with hyperkalemia?
Irregular pulse, bradycardia, irritability, anxiety, leg cramping and pain, weakness, abdominal cramps, diarrhea, dysrhythmias, and paresthesias.
