Study Notes
Management of Fluid & Electrolyte Alterations
- Ensure medications align with specific fluid and electrolyte imbalances (e.g., avoid potassium-sparing diuretics in hyperkalemia).
- Administer medications accurately, maintaining correct dosages and methods (e.g., dilute IV potassium to prevent cardiac complications).
- Monitor vital signs, lab values, and physical symptoms for treatment effectiveness, particularly for patients on high-dose diuretics.
Relationship with Other Systems
- Electrolytes like potassium and calcium are essential for cardiovascular health; imbalances can lead to arrhythmias or heart failure.
- Kidneys regulate fluid and electrolyte homeostasis; failure can result in hyperkalemia or hyponatremia.
- Hormones (e.g., aldosterone, ADH) control sodium and water balance; disorders like SIADH lead to imbalances.
- DKA patients require careful fluid resuscitation and potassium management due to insulin therapy's effect on potassium levels.
Collaboration in Care
- Work with physicians and endocrinologists to manage IV fluids, electrolyte replacements, and medication adjustments.
- Collaborate with dietitians to create nutritional plans to restore balance.
- Coordinate with pharmacists to ensure appropriate medication use and evaluate drug interactions affecting electrolyte levels.
Prioritizing Nursing Care
- Conduct comprehensive assessments to identify critical imbalances and symptoms (e.g., dysrhythmias in hyperkalemia).
- Implement emergency interventions (e.g., administer calcium gluconate for high potassium levels).
- Continuously reevaluate and adjust care plans based on patient response and lab results.
Pharmacology Principles Across the Lifespan
- Monitor for potential electrolyte depletion in patients on diuretics (e.g., hypokalemia with loop diuretics).
- Administer electrolyte supplements while considering contraindications and interactions.
- Understand fluid types (isotonic, hypertonic, hypotonic) and their appropriate use relative to patient conditions.
Risk Factors for Imbalances Across Lifespan
- Infants and children: Susceptible to dehydration due to higher metabolic rates and immature renal function.
- Older adults: Increased risk of imbalances from age-related kidney decline and chronic conditions (e.g., heart failure).
- Acute illness or trauma can lead to significant fluid/electrolyte disturbances (e.g., burns, sepsis).
- Chronic diseases (e.g., DKA, heart, kidney diseases) disrupt fluid and electrolyte balance.
- Certain medications (e.g., diuretics, corticosteroids) can cause electrolyte disturbances like hypokalemia or hypernatremia.
Prevention Strategies
- Educate patients about hydration and balanced electrolytes, especially during illness or extreme temperatures.
- Advocate for early monitoring of fluid intake/output among high-risk populations (e.g., infants, elderly).
- Encourage a balanced diet with adequate fluids and electrolyte-rich foods or supplements.
- Regularly adjust medications to minimize adverse effects on electrolyte balance, particularly for patients with chronic conditions.
