VN 22 Test 2 Flashcards
- Manifestations of hypovolemia and Labs
Thirst, dry mucus membranes
Cold clammy skin
Decreased skin tumor and decreased capillary refill
Postural hypotension, tachycardia, Tachypnea
Thready pulse
Decreased urine output, concentrated urine
Weakness, dizziness
Weight loss (may be weight gain from fluid that is trap)
Seizures, coma-Shock
Labs: HCT-increased, Specific gravity >1.030, increased BUN
- Education of Hypovolemia
Drink 8 glassed/ day
Respond to thirst
Avoid caffeine and alcohol
- Actions of Hypovolemia
MonitorI&Os
Monitor electrolytes
Administer ordered rehydration therapy
Monitor weight
Watch position changes
- Manifestations of hypervolemia
*SIADH monitor for hypervolemia manifestations
Weight gain is the most common
Jugular vein distention
Peripheral edema
Increase BP (Hypertension)
Dyspnea (Crackles, Pulmonary edema)
Muscle spasms
Seizure, coma
Labs: decreased HCT; low specific gravity
- Nursing Action of hypervolemia
Administer diuretics as ordered
Fluid restrictions as ordered
Restriction of sodium intake
Removal of fluid to treat ascites or pleural effusion
If dyspnea or orthopnea> Semi-Fowler’s
Strict I &O, lung sounds, daily weight, defrocked edema, reposition q 2 hours
Promotes rest and diuresis
Inspect skin care
- Nursing actions for fluid imbalance
Monitor intake and output
Monitor electrolyte levels
Auscultate lungs
Measure weights daily
- Risks/causes of hypokalemia
- Renal losses from diuretics(potassium-wasting diuretic), corticosteroids (NEED TO KNOW)
- manifestations of hypokalemia
Potassium < 3.5mEq/L
Muscle Weakness
U Wave
Decreased GI: lleus
Hyporeflexia
Shallow breathing
Weak irregular pulse
Fatigue
- risks/causes of hyperkalemia
-Severe tissue trauma
-Burns
-potassium sparing diuretic: Spironolactone
-Ace inhibitors
-Overdose IV potassium
- Manifestations of Hyperkalemia
Potassium >0.5 mEq/L
Abdominal Cramps

-Muscle weakness
-Elevated temp
-Tachycardia
- Weak, Thready pulses
- Respiratory arrest
- laboratory data for hyponatremia
Sodium and chloride go together. If one goes the other one goes as well
- manifestations of hypernatremia
Change (decrease) in level of consciousness
