How to Deal with Hyperkalemia Fast

The human body is an intricate symphony of interconnected systems, each meticulously regulated to maintain a delicate balance. Among the most crucial of these balances is the precise concentration of electrolytes, particularly potassium. When potassium levels in the blood surge above normal, a potentially life-threatening condition known as hyperkalemia arises. This isn’t just a minor blip on the health radar; it’s a medical emergency that demands swift, decisive action. Ignoring or delaying treatment for hyperkalemia can lead to severe cardiac arrhythmias, muscle weakness, paralysis, and in extreme cases, even death. Therefore, understanding how to deal with hyperkalemia quickly and effectively is not just beneficial, it’s essential for anyone concerned with optimal health – whether you’re a patient at risk, a caregiver, or simply an individual seeking comprehensive health knowledge.

This definitive guide will plunge into the depths of hyperkalemia, demystifying its causes, recognizing its subtle yet critical symptoms, and most importantly, providing a clear, actionable roadmap for rapid intervention. We will strip away the medical jargon, offering concrete examples and practical strategies for immediate management, ensuring that you are equipped to navigate this challenging condition with confidence and competence.

Unmasking the Silent Threat: What Exactly is Hyperkalemia?

Before we delve into rapid solutions, a foundational understanding of hyperkalemia itself is paramount. Potassium is a vital electrolyte, playing a critical role in nerve signal transmission, muscle contraction (especially heart muscle), and maintaining fluid balance. Normal serum potassium levels typically range from 3.5 to 5.0 milliequivalents per liter (mEq/L). Hyperkalemia is diagnosed when these levels exceed 5.0 mEq/L.

The severity of hyperkalemia is often categorized:

• Mild Hyperkalemia: 5.1 to 5.9 mEq/L

• Moderate Hyperkalemia: 6.0 to 7.0 mEq/L

• Severe Hyperkalemia: Above 7.0 mEq/L

It’s crucial to understand that even mild elevations can be dangerous, particularly in individuals with underlying heart conditions. The higher the potassium level, the greater the risk of serious complications.

The Culprits Behind the Surge: Why Does Hyperkalemia Occur?

Hyperkalemia doesn’t just appear out of thin air; it’s a consequence of an underlying issue that disrupts the body’s delicate potassium regulation. Identifying the root cause is often key to effective long-term management, but in an acute situation, immediate treatment takes precedence. Common culprits include:

• Kidney Dysfunction: The kidneys are the primary regulators of potassium excretion. When kidney function is impaired, due to chronic kidney disease, acute kidney injury, or even severe dehydration, potassium can accumulate in the bloodstream. Imagine a clogged drain; water (potassium) backs up because it can’t be flushed away.

• Medications: A wide array of medications can elevate potassium levels. These include:

  • ACE Inhibitors (e.g., lisinopril, enalapril) and Angiotensin Receptor Blockers (ARBs) (e.g., valsartan, losartan): Commonly prescribed for high blood pressure and heart failure, these drugs can reduce aldosterone production, a hormone that promotes potassium excretion.

  • Potassium-Sparing Diuretics (e.g., spironolactone, amiloride, triamterene): Unlike other diuretics that flush potassium, these specifically prevent its loss. While beneficial for certain conditions, they can cause hyperkalemia, especially in combination with other medications or kidney issues.

  • NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) (e.g., ibuprofen, naproxen): Prolonged or high-dose use of NSAIDs can impair kidney function, indirectly leading to potassium retention.

  • Beta-Blockers (e.g., propranolol, metoprolol): These medications can shift potassium out of cells into the bloodstream.

  • Digoxin: Toxicity from this heart medication can lead to hyperkalemia.

  • Heparin: In some cases, heparin can cause hypoaldosteronism, leading to elevated potassium.

• Excessive Potassium Intake: While less common as a sole cause in individuals with healthy kidneys, consuming large amounts of potassium-rich foods or supplements, especially in the presence of compromised kidney function, can contribute. Think of someone on dialysis who overindulges in bananas and oranges.

• Cellular Shift: Conditions that cause potassium to move out of cells and into the bloodstream:

  • Tissue Damage/Cell Lysis: Trauma, severe burns, rhabdomyolysis (muscle breakdown), and tumor lysis syndrome (rapid breakdown of cancer cells during chemotherapy) release intracellular potassium into the circulation.

  • Acidosis: Metabolic or respiratory acidosis can cause hydrogen ions to move into cells and potassium ions to move out, leading to hyperkalemia.

  • Insulin Deficiency: Insulin promotes potassium uptake into cells. In conditions like diabetic ketoacidosis, lack of insulin can lead to potassium exiting cells.

• Adrenal Insufficiency (Addison’s Disease): The adrenal glands produce hormones like aldosterone, which regulate potassium excretion. Insufficiency can lead to impaired potassium excretion.

• Pseudohyperkalemia: This is a false elevation of potassium due to issues with blood collection or handling, such as prolonged tourniquet application or vigorous fist clenching, which can cause red blood cells to lyse and release potassium. It’s crucial to rule this out, especially if the patient is asymptomatic.

Recognizing the Red Flags: Symptoms That Demand Attention

The insidious nature of hyperkalemia lies in its often subtle and non-specific symptoms, especially in its early stages. This makes early recognition challenging but critical. As potassium levels rise, the symptoms become more pronounced and potentially life-threatening.

Early and Non-Specific Symptoms:

These can be easily mistaken for other conditions, making a high index of suspicion vital, especially in individuals at risk.

• Fatigue and Weakness: A generalized feeling of being tired and lacking energy. Imagine feeling unusually drained after minimal effort.

• Nausea and Vomiting: Upset stomach, feeling like you might throw up, or actually vomiting. This can sometimes be dismissed as a minor digestive issue.

• Muscle Aches and Cramps: Similar to what you might experience after a strenuous workout, but without the preceding activity.

• Numbness or Tingling (Paresthesias): A pins-and-needles sensation, often in the extremities.

Moderate to Severe Symptoms (Requiring Immediate Intervention):

As hyperkalemia progresses, the symptoms become more alarming and are indicative of significant electrolyte imbalance.

• Muscle Weakness progressing to Paralysis: This is a direct consequence of potassium’s role in muscle function. It can start as difficulty moving limbs and progress to complete paralysis, including respiratory muscles, leading to breathing difficulties. Imagine struggling to lift your arm or feeling your legs give out.

• Bradycardia (Slow Heart Rate): The heart beats unusually slowly, which can reduce blood flow to vital organs.

• Palpitations: A sensation of the heart racing, pounding, or skipping beats, even though the overall rate might be slow. This is due to the heart’s electrical instability.

• Arrhythmias (Irregular Heartbeat): This is the most dangerous complication. Hyperkalemia can disrupt the heart’s electrical conduction system, leading to life-threatening rhythms like ventricular fibrillation or asystole (cardiac arrest).

• Shortness of Breath: If respiratory muscles are affected or if cardiac output is severely compromised, breathing can become labored.

• Abdominal Cramping and Diarrhea: While less specific, gastrointestinal symptoms can sometimes be present.

The ECG’s Tale: What the Heart Reveals

The electrocardiogram (ECG or EKG) is an indispensable tool for rapidly assessing the severity of hyperkalemia and guiding immediate treatment. Specific changes on the ECG indicate the heart’s electrical instability caused by elevated potassium. These changes often correlate with potassium levels, but individual responses can vary.

• Mild Hyperkalemia (K+ 5.5-6.5 mEq/L): Tall, peaked T waves (especially in precordial leads). These are narrow and symmetrical, unlike the broad, rounded T waves seen in other conditions. Think of them as sharply pointed mountains.

• Moderate Hyperkalemia (K+ 6.5-7.5 mEq/L):

  • Prolonged PR interval: The time it takes for the electrical impulse to travel from the atria to the ventricles is extended.

  • Loss of P wave: The atrial activity becomes less visible or disappears entirely.

  • Widening QRS complex: The ventricular depolarization takes longer, indicating impaired conduction within the ventricles.

• Severe Hyperkalemia (K+ > 7.5 mEq/L):

  • Sine wave pattern: A chaotic, undulating pattern that indicates profound cardiac electrical dysfunction, often preceding ventricular fibrillation or asystole. This is an ominous sign requiring immediate, aggressive intervention.

  • Ventricular fibrillation or Asystole: Complete cessation of effective cardiac pumping or no electrical activity, leading to cardiac arrest.

Actionable Insight: If an individual presents with any of the moderate to severe symptoms, especially in the context of risk factors for hyperkalemia, immediate medical attention is paramount. Do not wait. Call emergency services (e.g., 911 in the US, 115 in Vietnam) immediately.

The Rapid Response Plan: How to Deal with Hyperkalemia Fast

Dealing with hyperkalemia fast requires a multi-pronged approach aimed at three critical goals: stabilizing the heart, shifting potassium back into cells, and removing excess potassium from the body. The specific interventions chosen will depend on the severity of hyperkalemia, the presence of ECG changes, and the patient’s overall clinical condition. It’s crucial to reiterate that these interventions are typically administered in a hospital setting under strict medical supervision.

1. Cardioprotection: Stabilizing the Heart (Immediate Priority for ECG Changes)

When ECG changes indicative of hyperkalemia (especially widened QRS or sine wave) are present, protecting the heart from life-threatening arrhythmias is the absolute top priority. This is achieved by counteracting the effects of potassium on cardiac cell membranes.

• Intravenous Calcium (Calcium Gluconate or Calcium Chloride):
  • Mechanism: Calcium does not lower potassium levels but directly antagonizes the depolarizing effects of hyperkalemia on cardiac myocytes, stabilizing the cell membrane and reducing the risk of arrhythmias. Think of it as putting a shield around the heart.

  • Administration: Typically, 10 mL of 10% calcium gluconate is administered intravenously over 5-10 minutes. Calcium chloride is a more concentrated form and is often preferred in cardiac arrest situations.

  • Effect: The onset of action is almost immediate (within minutes), and the effects last for about 30-60 minutes. This provides a crucial window to initiate other potassium-lowering therapies.

  • Example: A patient arrives in the emergency room with severe muscle weakness and an ECG showing a widened QRS complex and absent P waves. The first line of treatment, even before definitive potassium levels are known, would be IV calcium to stabilize their heart and prevent immediate cardiac arrest.

2. Shifting Potassium Intracellularly: Moving Potassium Out of the Bloodstream

Once the heart is protected (if necessary), the next step is to rapidly shift potassium from the extracellular space (bloodstream) back into the cells. This doesn’t remove potassium from the body but temporarily lowers serum levels, buying more time for definitive removal strategies.

• Insulin and Dextrose:
  • Mechanism: Insulin promotes the uptake of potassium into cells, primarily into skeletal muscle and liver cells, by stimulating the Na+/K+-ATPase pump. Dextrose is co-administered to prevent hypoglycemia, as insulin will also lower blood glucose levels.

  • Administration: Typically, 10 units of regular insulin are given intravenously, followed by 25-50 grams of dextrose (e.g., 50-100 mL of D50W). For patients with elevated blood sugar, dextrose may be omitted or given in smaller amounts, but blood glucose must be closely monitored.

  • Effect: Onset of action is usually within 10-20 minutes, with peak effect at 30-60 minutes, lasting for several hours. This is a highly effective and widely used method.

  • Example: After receiving calcium, the patient’s ECG stabilizes, but their potassium level is 7.2 mEq/L. The next intervention would be an insulin-dextrose infusion to rapidly drive potassium into their cells, aiming for a quick reduction in serum levels.

• Beta-2 Agonists (e.g., Salbutamol/Albuterol):

  • Mechanism: High doses of inhaled or nebulized beta-2 agonists stimulate the Na+/K+-ATPase pump, promoting potassium entry into cells.

  • Administration: Often administered as a nebulized solution (e.g., 10-20 mg of albuterol).

  • Effect: Onset of action is around 30 minutes, with effects lasting 2-4 hours. While less potent than insulin-dextrose, it can be a useful adjunct or an alternative in patients where insulin is contraindicated or less desirable (though less common).

  • Example: A patient with mild-to-moderate hyperkalemia (without severe ECG changes) might receive nebulized salbutamol as part of their initial management plan, especially if they also have underlying respiratory issues.

• Sodium Bicarbonate (Less Frequently Used for Acute Hyperkalemia):

  • Mechanism: In the setting of metabolic acidosis, sodium bicarbonate can shift potassium into cells by correcting the acidosis. As pH increases, hydrogen ions move out of cells, and potassium moves in.

  • Administration: Administered intravenously.

  • Effect: Less reliable and slower acting than insulin-dextrose. Its primary role is in hyperkalemia with concomitant metabolic acidosis. It is generally not recommended as a first-line treatment for hyperkalemia alone.

  • Example: A patient presents with severe diabetic ketoacidosis and hyperkalemia. Correcting their acidosis with intravenous sodium bicarbonate would not only address the acidosis but also contribute to lowering their potassium by shifting it intracellularly.

3. Removing Potassium from the Body: The Definitive Solution

While shifting potassium intracellularly provides a temporary reprieve, the ultimate goal is to remove excess potassium from the body. These methods are slower acting but provide sustained potassium reduction.

• Diuretics (Loop Diuretics, e.g., Furosemide):
  • Mechanism: Loop diuretics increase potassium excretion in the urine by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased water and electrolyte loss.

  • Administration: Administered intravenously, especially in patients with adequate kidney function and signs of fluid overload.

  • Effect: Onset of action is typically within 15-30 minutes for IV furosemide. Its effectiveness depends on kidney function. It’s often used as an adjunct rather than a sole treatment for severe hyperkalemia.

  • Example: A patient with moderate hyperkalemia and good kidney function might receive furosemide to help them excrete excess potassium through increased urination. This is particularly useful if fluid overload is also a concern.

• Potassium Binders (Cation Exchange Resins, e.g., Sodium Polystyrene Sulfonate – SPS/Kayexalate):

  • Mechanism: These resins exchange potassium ions for other ions (like sodium or calcium) in the gastrointestinal tract, thereby preventing potassium absorption and promoting its excretion in feces.

  • Administration: Can be given orally (mixed with water or sorbitol, though sorbitol co-administration is now generally avoided due to gastrointestinal complications) or rectally as an enema.

  • Effect: Onset of action is slow (hours), so they are not suitable for acute, life-threatening hyperkalemia but are excellent for sustained reduction or preventing recurrence.

  • Example: After initial emergency measures stabilize a patient with chronic kidney disease and hyperkalemia, they might be given oral SPS to help prevent their potassium from rising again over the next few hours and days.

• Hemodialysis:

  • Mechanism: This is the most effective and rapid method for removing potassium from the body. Blood is drawn from the patient, passed through a dialyzer (artificial kidney) where excess potassium (and other waste products) are removed, and then returned to the patient.

  • Administration: Performed in a specialized dialysis unit.

  • Effect: Immediate and highly efficient in lowering potassium levels.

  • When Indicated: Reserved for severe, refractory hyperkalemia (not responding to other treatments), patients with end-stage renal disease, or those with significant kidney failure where other methods are ineffective.

  • Example: A patient with severe hyperkalemia (e.g., K+ > 7.5 mEq/L) and significant ECG changes who is also anuric (not producing urine) due to acute kidney injury would likely be taken for emergency hemodialysis as it offers the fastest and most complete potassium removal.

A Note on Oral Intake and Lifestyle Adjustments (for stable patients)

While not part of immediate, fast-acting treatment, managing dietary potassium is crucial for long-term control and prevention of recurrence once the acute crisis is averted.

• Dietary Restriction: Educate patients on high-potassium foods to limit or avoid. Examples include:
  • Fruits: Bananas, oranges, potatoes (especially skins), tomatoes, avocados, prunes, dried fruits.

  • Vegetables: Spinach, broccoli, certain beans and lentils.

  • Other: Salt substitutes (often potassium chloride), nuts, chocolate, dairy products (in large quantities).

• Review Medications: Work with healthcare providers to review and potentially adjust medications that contribute to hyperkalemia. This might involve reducing dosages, switching to alternative drugs, or adding potassium-wasting diuretics if appropriate.

• Address Underlying Cause: Long-term management involves treating the root cause of hyperkalemia, whether it’s optimizing kidney function, managing heart failure, or addressing adrenal insufficiency.

A Step-by-Step Action Plan for Suspected Hyperkalemia (In a Medical Setting)

This is a simplified overview of how medical professionals approach suspected hyperkalemia.

1. Immediate Assessment & ECG:
   • Rapidly assess vital signs (heart rate, blood pressure, respiratory rate).

   • Obtain a 12-lead ECG immediately. Look for peaked T waves, prolonged PR, widened QRS, or sine wave pattern.

   • Action: If ECG changes are present, start IV calcium immediately (Calcium Gluconate 10%, 10mL IV over 5-10 min).

2. Blood Work:

   • Draw blood for urgent serum potassium, creatinine (to assess kidney function), blood glucose, and other electrolytes.

   • Action: While waiting for lab results, if strong suspicion of hyperkalemia exists based on symptoms and ECG, proceed with treatments.

3. Potassium Shifting (If K+ is high or symptoms/ECG warrant):

   • Administer IV Insulin and Dextrose (e.g., 10 units regular insulin IV with 25-50g Dextrose IV).

   • Consider nebulized Salbutamol (10-20mg).

4. Potassium Removal (For sustained reduction):

   • If kidney function is adequate and no fluid overload, consider IV Furosemide.

   • Administer oral or rectal Potassium Binders (e.g., SPS) for slower, sustained potassium removal, but not for acute emergencies.

5. Consider Dialysis:

   • If severe hyperkalemia persists despite medical therapy, if there are life-threatening ECG changes that are not resolving, or if the patient has end-stage renal disease/acute kidney injury, prepare for urgent hemodialysis.
6. Continuous Monitoring:
   • Continuously monitor cardiac rhythm (ECG monitor).

   • Repeat serum potassium levels frequently (e.g., every 1-2 hours) to assess response to treatment.

   • Monitor blood glucose levels, especially after insulin administration.

7. Address Underlying Cause:

   • Once stabilized, investigate and treat the primary cause of hyperkalemia. This might involve adjusting medications, managing kidney disease, or treating infections.

Concrete Examples and Scenarios for Rapid Management

Let’s illustrate these principles with real-world (though simplified) scenarios.

Scenario 1: The Cardiac Emergency

• Patient: 68-year-old male with a history of chronic kidney disease and heart failure, brought to the ER by ambulance.

• Symptoms: Profound muscle weakness, lethargy, and reports of feeling his “heart skip beats.”

• Initial Assessment: Heart rate 45 bpm, blood pressure 90/60 mmHg.

• ECG: Shows wide QRS complexes, no visible P waves, and tall, peaked T waves.

• Urgent Labs: Potassium likely to be severely elevated (>7.5 mEq/L).

• Immediate Action Plan (within minutes of arrival):

  1. IV Calcium Gluconate: 10 mL of 10% IV immediately. This is to stabilize the heart and prevent progression to cardiac arrest.

  2. IV Insulin and Dextrose: 10 units regular insulin IV followed by 50 mL D50W IV. This will rapidly shift potassium into cells.

  3. Prepare for Dialysis: Given his history of kidney disease and severe ECG changes, emergent hemodialysis will likely be necessary as the definitive treatment for potassium removal.

  4. Continuous ECG Monitoring: To observe for resolution of ECG changes and any arrhythmias.

  5. Repeat Potassium Levels: Every hour to track response.

Scenario 2: The Diabetic with Acute Kidney Injury

• Patient: 55-year-old female with poorly controlled diabetes presenting with severe dehydration, nausea, and decreased urine output for 2 days.

• Symptoms: Generalized weakness, abdominal pain, and significant thirst.

• Initial Assessment: Appears acutely ill, signs of dehydration.

• ECG: Mildly peaked T waves.

• Urgent Labs: Potassium 6.8 mEq/L, Creatinine significantly elevated, Blood Glucose 450 mg/dL, with metabolic acidosis.

• Immediate Action Plan:

  1. Fluid Resuscitation: IV fluids to address dehydration and improve kidney perfusion.

  2. IV Insulin and Dextrose: Although her blood sugar is high, insulin is crucial for shifting potassium. Dextrose may be omitted initially, or a lower dose given, with very close glucose monitoring.

  3. Sodium Bicarbonate: Given the presence of significant metabolic acidosis, IV sodium bicarbonate can help correct the acidosis and further facilitate potassium shift.

  4. Furosemide: If fluid status improves and she starts to produce urine, a loop diuretic like furosemide can aid in potassium excretion.

  5. Address Underlying Cause: Aggressively manage her diabetic ketoacidosis and acute kidney injury.

Scenario 3: Medication-Induced Hyperkalemia (Stable Patient)

• Patient: 72-year-old male on Lisinopril and Spironolactone for heart failure, presenting for a routine check-up.

• Symptoms: No symptoms reported.

• Initial Assessment: Stable vital signs.

• ECG: Normal.

• Routine Labs: Potassium 5.6 mEq/L (mild hyperkalemia).

• Immediate Action Plan (Less urgent, but still requires prompt action):

  1. Review Medications: Immediately review his current medications. The combination of Lisinopril and Spironolactone is a common cause of hyperkalemia.

  2. Dietary Review: Assess his dietary habits for high-potassium foods/supplements.

  3. Consider Medication Adjustment: Consult with his physician to potentially lower the dose of spironolactone or switch to a different diuretic if clinically appropriate. Lisinopril might also need adjustment. Never adjust medication without a physician’s guidance.

  4. Oral Potassium Binder: Prescribe an oral potassium binder like Sodium Polystyrene Sulfonate to gradually reduce and maintain potassium levels.

  5. Repeat Potassium Levels: In 24-48 hours to assess the effect of interventions.

  6. Patient Education: Provide clear instructions on low-potassium diet and symptoms to watch for.

Preventing Recurrence: Proactive Strategies for Long-Term Health

Dealing with hyperkalemia fast is crucial, but preventing its recurrence is equally vital for long-term health and well-being. This involves a multi-faceted approach focused on identifying and managing underlying risk factors.

1. Medication Management: A Critical Review

As highlighted, medications are frequent culprits in hyperkalemia. Proactive management involves:

• Regular Medication Review: Patients on medications known to cause hyperkalemia (ACE inhibitors, ARBs, potassium-sparing diuretics, NSAIDs) should have their potassium levels monitored regularly, especially when initiating treatment or increasing dosages.

• Dosage Adjustment/Alternative Medications: If hyperkalemia develops, the prescribing physician may need to adjust the dosage or switch to an alternative medication that carries less risk of elevating potassium.

• Patient Education: Patients must be fully aware of the medications they are taking, their potential side effects, and the importance of adhering to prescribed monitoring schedules. They should never stop or change medications without consulting their doctor.

2. Dietary Awareness: Smart Food Choices

Diet plays a significant role, especially in individuals with compromised kidney function.

• Low-Potassium Diet: Patients at risk should be educated on foods that are high in potassium and should be limited or avoided. This isn’t about eliminating potassium entirely (which is impossible and unhealthy), but about making informed choices.
  • Examples to Limit: Bananas, oranges, potatoes (especially baked with skin), tomatoes, avocados, dried fruits, spinach, beans, lentils, whole grains, nuts, chocolate, and potassium-containing salt substitutes.

  • Examples of Lower Potassium Options: Apples, berries, grapes, green beans, carrots, white rice, pasta, lean meats.

• Food Preparation: Boiling certain vegetables (like potatoes) can help leach out some potassium, but this should be discussed with a dietitian.

• Hydration: Maintaining adequate hydration, especially in hot climates, can support kidney function and help in electrolyte balance.

3. Vigilant Monitoring: Keeping an Eye on Levels

• Regular Blood Tests: Individuals with kidney disease, heart failure, diabetes, or those on high-risk medications should undergo regular blood tests to monitor their potassium levels. The frequency will depend on the individual’s condition and risk profile.

• Symptom Awareness: Educate patients and caregivers on the symptoms of hyperkalemia, no matter how subtle. Early recognition can prevent progression to severe complications.

• Home Monitoring (Limited Cases): For some patients, home blood pressure monitoring might be recommended, but direct potassium monitoring at home is not generally feasible.

4. Managing Underlying Conditions: The Holistic Approach

Treating the primary disease responsible for hyperkalemia is fundamental to long-term control.

• Kidney Disease: Optimal management of chronic kidney disease, including dialysis for end-stage renal disease, is paramount.

• Heart Failure: Effective management of heart failure can improve kidney perfusion and reduce medication burden that contributes to hyperkalemia.

• Diabetes: Strict blood glucose control in diabetic patients can prevent diabetic ketoacidosis and its associated electrolyte imbalances.

• Adrenal Insufficiency: Appropriate hormone replacement therapy for Addison’s disease will normalize potassium levels.

5. Avoiding Pseudohyperkalemia: Proper Blood Collection

Educate healthcare professionals on proper blood collection techniques to avoid falsely elevated potassium readings, which can lead to unnecessary anxiety and interventions.

• Avoid prolonged tourniquet application.

• Avoid excessive fist clenching during blood draw.

• Process blood samples quickly.
