Study Notes
Fluid Volume Deficit
- Focus on circulation, affecting heart's oxygenated blood delivery.
-
Causes:
- Hypovolemia: Both fluid and electrolyte loss.
- Dehydration: Fluid loss only.
- Hemorrhage: Blood loss from various sources (e.g., gunshot, GI bleed).
- GI Issues: Prolonged vomiting, diarrhea, NG tube suction.
- Third Spacing: Fluid shift to non-beneficial areas (e.g., liver cirrhosis). Weight loss, in this case, is not a reliable indicator.
-
Assessment:
-
Vitals:
- Decreased blood pressure, due to reduced blood volume.
- Increased heart rate, compensating for reduced blood volume.
- Increased respiratory rate, compensating for reduced oxygen circulation.
-
Cardiac:
- Weak, thready pulse, due to shunting of blood to vital organs.
- No distended neck veins (JVD), distinguishing from fluid overload.
-
Respiratory:
- Dyspnea (shortness of breath) with exertion, due to reduced oxygen circulation.
-
Neurologic:
- Confusion and fatigue, due to decreased oxygenation.
-
Renal:
- Decreased urine output, concentrated urine due to kidney's fluid retention efforts.
-
Skin:
- Dry, cracked mucous membranes, dehydration sign.
- Poor skin turgor (tenting), due to decreased elasticity.
- Potential weight loss, except in third spacing.
-
Vitals:
-
Labs:
- Elevated serum osmolality, higher concentration in the reduced blood volume.
- Elevated urine osmolality and specific gravity, concentrated urine.
- Increased hemoglobin and hematocrit (except in hemorrhage), due to concentration effect, not increased blood cell production.
- Elevated BUN and creatinine levels, potential kidney dysfunction due to reduced oxygen flow.
Fluid Volume Overload
-
Causes:
- Increased sodium content (high intake, hypertonic solutions, rapid IV).
- Heart failure: Impaired heart pumping, fluid buildup.
- Renal failure: Kidney dysfunction, fluid and toxin buildup.
- Liver cirrhosis: Fluid shift to peritoneal cavity.
-
Assessment:
-
Vitals:
- Increased blood pressure, due to increased blood volume.
- Increased heart rate (initial compensation, potentially decreased if heart struggles).
- Increased respiratory rate, compensation attempt.
-
Cardiac:
- Full, bounding pulse, due to increased blood volume.
- Distended neck veins (JVD), fluid buildup in the veins.
-
Respiratory:
- Dyspnea, fluid buildup.
- Crackles (moist rales) in lungs, fluid accumulation in alveoli.
-
Neurologic:
- Altered mental status, possible disorientation due to organ dysfunction.
- Fatigue and weakness, from organ impact.
-
Renal:
- Increased urine output (initially), dilute urine, kidney compensation.
-
Vitals:
- Skin: - Pink, moist mucous membranes, hydrated, - Potential jugular vein distention - Elastic skin turgor - No tenting - Edema
Fluid Volume Overload (Updated)
-
Clinical Manifestations:
- Kidneys: Increased urinary output with dilute urine.
- Skin: Hydrated; pink, moist mucous membranes; potential JVD; elastic skin turgor; no tenting; edema.
- Respiratory: Possible lung crackles.
- Cardiovascular: Tachycardia
- General: Increased body weight.
-
Lab Values:
- Decreased hemoglobin and hematocrit, dilution effect.
- Decreased urine osmolality and specific gravity, dilute urine.
- BUN and creatinine: May be elevated, depending on cause (kidney or organ failure).
-
Interventions:
- Treat underlying cause.
- Fluid restrictions (1200ml/day or less, Client education); avoid water pitchers.
- Sodium restrictions (2 grams/day or less; Client education on labels).
- Diuretics (e.g., furosemide).
- Dialysis (severe cases).
Fluid Volume Deficit (Updated)
-
Clinical Manifestations:
- Kidneys: Decreased urinary output, concentrated urine.
- Skin: Dry, cracked mucous membranes; poor skin turgor, tenting observed; potentially dry skin.
- Respiratory: Possible increased respiratory rate.
- Cardiovascular: Hypotension, tachycardia.
- General: Decreased body weight.
-
Lab Values:
- Increased hemoglobin and hematocrit (except hemorrhage).
- Increased urine osmolality and specific gravity, concentrated urine.
- BUN and creatinine: Usually elevated, potentially decreased in hemorrhage.
-
Interventions:
- Address underlying cause promptly.
- Shock position (head elevated, legs lowered).
- Fluid replacement (oral for mild, IV isotonic for severe).
- Isotonic solutions (e.g., LR, 0.9% NaCl) mimic plasma.
- Vasopressors (severe cases).
- Caution with oral fluids in confused/unstable clients (aspiration risk).
General Assessment Considerations
- Daily weights (consistent) are the most accurate for fluid volume status. Weights should be taken in the morning, same clothing, same scale, using a consistent linen piece.
- Monitor vital signs (blood pressure, heart rate, respiratory rate, temperature).
- Perform physical assessment (skin turgor, mucous membranes, lung sounds).
Key Points
- Fluid Volume Overload: Excess fluid in the body.
- Fluid Volume Deficit: Insufficient fluid in the body.
- Isotonic Solutions: IV fluids with the same concentration as blood; do not cause fluid shifts (examples: LR, 0.9% NaCl).
- Diuretics: Medications that remove excess fluid (example: furosemide).
- Vasopressors: Medications increasing blood pressure (example: norepinephrine).
