Electrolyte imbalances S.G Test 2-DONE Flashcards
- Manifestations of hypovolemia/fluid volume deficit (pp slide 18)
Most common fluid imbalance
-thirst, dry mucus membranes
-decreased urine output/concentrated urine
-cold clammy skin
-decreased turgor
-decreased capillary refill
-Postural hypotension, tachycardia, tachypnea
-weakness, dizziness
-thready pulse
-weight loss
-Seizures, coma-shock
- Labs for hypovolemia(pp slide 18)
-increased HCT
-increased BUN
-Urine specific gravity > 1.030
- Nursing education for hypovolemia , nursing actions (pp slide 18)
Nursing education:
-drink 8 glasses/day
-respond to thirst
-avoid caffeine & alcohol
Nursing Actions:
-monitor I &o’s, monitor weight
-monitor electrolytes
-administer ordered hydration therapy
-watch position changes
Manifestations for HYPERvolemia, labs(pp slide 22)
SIADH monitor for hypervolemia manifestations
-weight gain (most common)
-jugular vein distention
-peripheral & pulmonary edema (crackles in lungs)
-Increase BP
-Dyspnea
-Muscle spasms
-Seizures, coma
LABS:
Decreased HCT; low specific gravity
Nursing actions for HYPERvolemia(pp slide 23)
-Administer diuretics as ordered
-Fluid restriction as ordered
-restrict sodium intake
-removal of fluid to treat ascites or pleural effusion
-If dysphasia or Orthopnea> Semi- Fowler’s
-Strict I & O, lung sounds, daily weight, degree of edema reposition every 2 hrs
-Promote rest & diuresis
-Inspect skincare
Causes of HYPERvolemia
-Liver failure
-renal failure
- cirrhosis
-cardiovascular
- Risks/causes of hypokalemia (PP slide 15)
-loss of K+ via the kidneys or GI tract: N/V/D
-increased shift of K+ from ECF to ICF
- dietary K+ (rare)
-Renal losses from diuretics, corticosteroids
*Corticosteroids & potassium wasting diuretics (furosemide) = main cause for hypokalemia
- manifestations of hypokalemia (wk4 pp slide 16)
Potassium <3.5
-muscle weakness
-U wave
-decreased GI: ileus
-Hyporeflexia
-shallow breathing
-weak irregular pulse
-fatigue
- risks/causes of hyperkalemia (pg.186)
-ace inhibitors
-IV potassium (too much)
-renal failure
-severe burns/crushing injuries
-potassium-sparing diuretics
-overuse of potassium supplements
-salt substitutes
-potassium-rich foods
-Addison’s disease
-rapid administration of parental potassium salts
Manifestations of hyperkalemia: (pp slide 13)
-Potassium >5.0 mEq/L
-abdominal cramps
-diarrhea
-restlessness
-hypotension, bradycardia, Arrhythmia
-muscle weakness
-increased DTR(deep tendon reflex)
-Tall peaked T waves
-Seizures
- laboratory data for hyponatremia (pp slide 10)
Sodium <135 mEq/L
Addison’s disease
Sodium & Chloride go together
Manifestations for hyponatremia (pp slide 10)
-mental confusion
-muscular weakness
-elevated temp.
-tachycardia
-weak, thready pulses
-respiratory arrest
Priority interventions for hyponatremia (pp slide 10)
-Assess airway
-reduce diuretic dosage
-fluid restriction
-hypertonic solution (3% or 5% NaCI)
- manifestations of hypernatremia (pp slide 8)
-sodium >145 mEq/L
Cushing’s syndrome
-extreme thirst
-dry flushed skin
-low grade fever
-Orthostatic Hypotension
- decreased level of consciousness
Late signs:
-Red beefy tongue
-n/v
-increased muscle tone (twitching)
Priority nursing interventions for hypernatremia (pp slide 8)
-prevent dehydration/replace fluids
-sodium restriction
-diuretics (promote sodium excretion)
-hypotonic solution (0.225% or 0.45%NaCL)
