The normal serum potassium concentration ranges from 3.5 to 5.0 mEq/L. Strategies to prevent chronic hyperkalemia include instructing patients to eat a low-potassium diet, discontinuing or adjusting medications, avoiding nonsteroidal anti-inflammatory drugs, and adding a diuretic if the patient has sufficient renal function. Start a strict input and output monitoring. To provide information on hyperkalemia and its pathophysiology in the simplest way possible. Careful monitoring during treatment is essential because supplemental potassium is a common cause of hyperkalemia in hospitalized patients.21 The risk of rebound hyperkalemia is higher when treating redistributive hypokalemia. The most common cause is excess loss from the kidneys or gastrointestinal tract.

This care plan handbook uses an easy, three-step system to guide you through client assessment, nursing diagnosis, and care planning. Potassium is important in regulating the osmolarity of ECF by exchanging it with sodium. Used in the treatment of potassium deficiency when oral replacement is not feasible. Potassium regulates fluid and facilitates muscular contraction and nerve activity. Teach and assist the client with range-of-motion (ROM) exercises, as tolerated.Improves muscle tone and reduces muscle cramps and pain. Nursing Diagnosis Excess Fluid Volume May be related to Excess fluid or sodium intake. In response to acidosis, extracellular hydrogen is exchanged for intracellular potassium, although the net result is highly variable and depends in part on the type of acidosis; metabolic acidosis produces the greatest effect.26 Because 98% of total body potassium is intracellular, any process that increases cell turnover, such as rhabdomyolysis, tumor lysis syndrome, or red blood cell transfusions, can result in hyperkalemia. Findings on ECG are neither sensitive nor specific for hyperkalemia. Stress the importance of the clients notifying future caregivers when a chronic condition potentiates the development of hyperkalemia, such as oliguric renal failure.May help prevent hyperkalemia recurrences. Anna Curran. His temperature is 37.4 C, heart rate is 122 beats per minute, blood pressure is 142/84 mmHg, respirations are 20 breaths per minute, and oxygen saturation is 98% on room air. In general, hypokalemia is associated with diagnoses of cardiac disease, renal failure, malnutrition, and shock. Hypokalemia can become life threatening if it affects the heart muscle, causes paralysis, or impairs the functioning of the lungs. Therefore, a first priority is determining the need for urgent treatment through a combination of history, physical examination, laboratory, and electrocardiography findings. 3. Our website services and content are for informational purposes only. Electrocardiogram (ECG). Hypothermia and increased blood cell production (for example, leukemia) are additional risk factors for developing hypokalemia. The patient is experiencing weakness, heart palpitations, and shortness of breath. 2697-2729). This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. To conclude, here we have formulated a scenario-based nursing care plan for Hypokalemia. When intravenous potassium is used, standard administration is 20 to 40 mmol of potassium in 1 L of normal saline. 2. 2. The majority of potassium is stored in the intracellular compartment. Patients with a serum glucose level of more than 250 mg per dL (13.9 mmol per L) typically do not require coadministration of glucose. Low potassium (hypokalemia) - Mayo Clinic Although redistributive hyperkalemia is uncommon, a cautious approach is warranted because treatment may not involve attempts to eliminate potassium, and correction of the underlying problem can provoke rebound hypokalemia. 1. Harding, M. M., Kwong, J., Roberts, D., Reinisch, C., & Hagler, D. (2020). 6. Therefore, potassium helps control the fluid inside the cell, while sodium . Short-term goal: By the end of the shift the patient will experience a resolution of heart palpitations and shortness of breath, with no further PVCs seen on ECG.Advertisementsif(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'nurseship_com-leader-2','ezslot_8',642,'0','0'])};__ez_fad_position('div-gpt-ad-nurseship_com-leader-2-0'); Long-term goal: The patient will maintain a normal potassium level, monitoring for recurrent signs and symptoms of hypokalemia. For example, a decline in serum potassium from 3.8 to 2.9 mEq per L (3.8 to 2.9 mmol per L) roughly corresponds to a 300-mEq (300-mmol) reduction in total body potassium. Hyperkalemia-induced ventricular fibrillation is treated with calcium. Volume depletion from vomiting, diarrhea, increased sweating, and excessive laxative use can all lead to hypokalemia. Please follow your facilities guidelines and policies and procedures. Encourage intake of carbohydrates and fats and low potassium food such as pineapple, plums, strawberries, carrots, cauliflower, corn, and whole grains.Reduces exogenous sources of potassium and prevents metabolic tissue breakdown with the release of cellular potassium. Her nursing career has brought her through a variety of specializations, including medical-surgical, emergency, outpatient, oncology, and long-term care. Implement safety measures when administering IV potassium.Because IV potassium infusion can cause phlebitis as a complication, the nurse should regularly check the IV site for indications of phlebitis or infiltration. Copyright 2015 by the American Academy of Family Physicians. Assess the patients neuromuscular status.Potassium is utilized by muscles to transmit electrical signals to the brain leading to muscle contraction. Teach the patient on how to follow a low potassium diet. Activity intolerance related to insufficient potassium to support regular body functions as evidenced by weakness, palpitations, and shortness of breath. St. Louis, MO: Elsevier. Also, the administration of potassium to treat or prevent hypokalemia can inadvertently cause hyperkalemia.19, ACE inhibitors contributed to one-half of all cases of drug-induced hyperkalemia in one sample, and approximately 10% of outpatients who start an ACE inhibitor or an ARB will develop hyperkalemia within one year.23,28 The incidence of hyperkalemia associated with use of potassium-sparing diuretics has risen since adding spironolactone to standard therapy was shown to reduce morbidity and mortality in patients with congestive heart failure.29 Dual treatment with an ACE inhibitor and an ARB increases the risk of harmful adverse effects, including hyperkalemia, and should be avoided.11 Other commonly used medications known to cause hyperkalemia include trimethoprim, heparin, beta blockers, digoxin, and nonsteroidal anti-inflammatory drugs.3, As with hypokalemia, the immediate danger of hyperkalemia is its effect on cardiac conduction and muscle strength, and initial efforts should focus on determining the need for urgent intervention (Figure 2).14,30 The absence of symptoms does not exclude severe hyperkalemia, because hyperkalemia is often asymptomatic. Imbalanced Nutrition Less than Body requirements, BPH Nursing Diagnosis and Nursing Care Plan, Legionnaires Disease Nursing Diagnosis and Nursing Care Plan. Low potassium (hypokalemia) refers to a lower than normal potassium level in your bloodstream. Administer the following drugs, as prescribed: Also, potassium-rich foods in the diet help maintain potassium balance. Some medications can cause abnormal blood potassium levels. Buy on Amazon. Low potassium diet include eating apples, berries, pineapple, breads, and cereals. Cardiac enzymes are normal but his potassium level is 2.8 mmol/L. PO potassium can cause stomach upset so its best to administer with food or after meals. Nurses pocket guide: Diagnoses, interventions, and rationales (15th ed.). 2023 nurseship.com. Beta-blockers. (2022). Ackley and Ladwigs Nursing Diagnosis Handbook: An Evidence-Based Guide to Planning CareWe love this book because of its evidence-based approach to nursing interventions. Diabetic ketoacidosis. Hypokalemia Nursing Care Plan - RN speak Symptoms include fatigue, weakness, nausea, heart palpitations, shortness of breath, leg cramps, polyuria, polydipsia, and constipation. Muscle wasting and paralysis can result from very low potassium levels. Nursing Diagnosis: Risk for Hypernatremia Potentially Related To Dehydration Severe diarrhea Fever Vomiting Poorly controlled diabetes Certain medications Kidney disease Diabetes insipidus Extensive burns Evidenced By Extreme thirst Fatigue Headache Nausea Lethargy Confusion Muscle twitching or spasms Seizures Coma Desired Outcomes Copyright 2023 American Academy of Family Physicians. To replace potassium lost by the body. Studies suggest that some antibiotics can cause high potassium levels. For the past few nights, he has had severe leg cramps that have woken him up. Determine the patients independence in performing activities.Promote and assist in patient ambulation and independence in self care. You have diarrhea. Hypokalemia occurs when potassium falls below 3.6mmol/L and hyperkalemia occurs when potassium level in the blood is greater than 5.2mmol/L. For hypokalemia associated with diuretic use, stopping the diuretic or reducing its dosage may be effective.15 Another strategy, if otherwise indicated to treat a comorbid condition, is use of an angiotensin-converting enzyme (ACE) inhibitor, angiotensin receptor blocker (ARB), beta blocker, or potassium-sparing diuretic because each of these drugs is associated with an elevation in serum potassium. Check for safety hazards in the patients environment.Assess the following environmental factors: 5. Review the patients current medications.Imbalanced potassium and the use of cardiac medications (used to treat dysrhythmias) greatly increase the risk for muscle weakness and potential falls. After 1 hour of health teaching, the client will be able to: Identify measures to prevent hypokalemia. Consider IV maintenance fluids with potassium added. Psychiatric Nursing . Generally, hypokalemia is a medical, not a surgical, condition. A focused history includes evaluation for possible GI losses, review of medications, and assessment for underlying cardiac comorbidities. The recommended dietary replacement for potassium is 40 to 60 mEq/L/day. Identification and treatment of concurrent hypomagnesemia are also important because magnesium depletion impedes potassium repletion and can exacerbate hypokalemia-induced rhythm disturbances.16,17. Diuretics (water retention relievers) Excessive laxative use. Monitor for signs and symptoms of hypokalemia: Assist client in selecting foods rich in potassium as such as banana, fruit juices, melon, citrus fruits,and fresh vegetables. Potassium also maintains normal neuromuscular contraction by participation in the sodium-potassium pump. Arrhythmias associated with hypokalemia include sinus bradycardia, ventricular tachycardia or fibrillation, and torsade de pointes.19 Although the risk of ECG changes and arrhythmias increases as serum potassium concentration decreases, these findings are not reliable because some patients with severe hypokalemia do not have ECG changes.20, The immediate goal of treatment is the prevention of potentially life-threatening cardiac conduction disturbances and neuromuscular dysfunction by raising serum potassium to a safe level. She found a passion in the ER and has stayed in this department for 30 years. Some of the potassium ions are lost when vomiting occurs. Some types of diuretics increase potassium excretion through the kidneys. The physical examination should include assessment of blood pressure and intravascular volume status to identify potential causes of kidney hypoperfusion, which can lead to hyperkalemia. Additionally, this sampleHypokalemianursing care plan comprises nursing assessment, NANDA nursing diagnosis, goal, and interventions with rationales. Because potassium can only be administered slowly and in small doses via a peripheral IV, a central line is recommended to correct hypokalemia more quickly. It is also needed in the formation of muscles in the body. Nurses must closely monitor patients lab results and correct imbalances to prevent complications. NurseTogether.com does not provide medical advice, diagnosis, or treatment. Medical-surgical nursing: Concepts & practice (3rd ed.). Hyperkalemia - SlideShare The search included meta-analyses, randomized controlled trials, clinical trials, and reviews. The patient says: Ive been on Lasix for years now so I know what to expect, but I still think Ive been urinating more than usual. He also reports thirst and constipation, but he was careful not to drink excess water because of his heart failure. The main source of potassium is from food. 4. These can include assistive devices, braces, and adaptive equipment. Nursing diagnosis:- Potential for dysrrythmia r/t hyperkalemia. Monitor heart rate and rhythm. Significant leukocytosis (> 75,000 cells per mm, Acute kidney injury/chronic kidney disease, Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, Calcium chloride, 10 mL of 10% solution IV over 5 to 10 minutes, or calcium gluconate, 30 mL of 10% solution IV over 5 to 10 minutes, Stabilizes cardiac muscle cell membrane; no effect on serum potassium or total body potassium, May potentiate digoxin toxicity; calcium chloride can cause phlebitis and tissue necrosis, Regular insulin, 10 units IV followed immediately by 50 mL of 50% glucose (25 g) IV, Shifts potassium into cells; no effect on total body potassium, May cause hypoglycemia; glucose is unnecessary if serum glucose level is > 250 mg per dL (13.9 mmol per L); additive effect when combined with albuterol, Can cause tachycardia and thus should be used with caution in patients with underlying heart disease; potassium-lowering effect not reliable in all patients; additive effect when combined with insulin, Sodium polystyrene sulfonate (Kayexalate), Binds potassium in exchange for sodium; lowers total body potassium, Association with gastrointestinal complications, particularly when combined with sorbitol; should be avoided in patients at risk of abnormal bowel function. and, i didn't Hypokalemia is defined as a serum potassium level below 3.5 mEq/L. Bradycardia can progress to cardiac fibrillation and arrest. 2. Potassium is mainly excreted in the kidneys. Nursing diagnoses handbook: An evidence-based guide to planning care. Potassium is contraindicated if oliguria or anuria is present. Depletion of potassium occurs and then leads to altered electrolyte balance in the body. While mild hyperkalemia is usually asymptomatic, high potassium levels may cause life-threatening cardiac arrhythmias, muscle weakness, or paralysis. RN, BSN, PHNClinical Nurse Instructor, Emergency Room Registered NurseCritical Care Transport NurseClinical Nurse Instructor for LVN and BSN students. Patients with a history of congestive heart failure or myocardial infarction should maintain a serum potassium concentration of at least 4 mEq per L (4 mmol per L). The patient needs to avoid foods high in potassium such as bananas. Potassium levels can fluctuate in the treatment of DKA. Hypokalemia. Weight should be performed every day to help assess fluid volume status. St. Louis, MO: Elsevier. 5. a nursing problem (nursing diagnosis) is based upon the symptoms the patient is having and not solely on lab data. Blood pressure medications. Hyponatremia (decreased sodium in blood) OR hypernatremia (increased sodium in the blood) could be present depending on the types of fluid lost. Elsevier Health Sciences. Potassium helps carry electrical signals to cells in your body.

Nursing Diagnosis: Deficient Knowledge related to new diagnosis of hyperkalemia as evidenced by patients verbalization of I want to know more about my new diagnosis and care. When defined as a value of less than 3.6 mmol of potassium per . Muscular cramps or twitching hyperkalemia or high potassium levels in the blood can cause alteration in the voltage of the nerve cells causing unregulated muscle contractions. (See "Causes of hypokalemia in adults".). Upon assessment, the patient is alert and oriented and follows commands appropriately. Breathing requires many muscles, particularly the diaphragm, which require potassium in order to work properly. Hypokalemia can cause muscle weakness, paralysis, breathing and swallowing problems (because of muscle paralysis), and irregular heart rate in serious conditions. A potassium deficiency can result in shortness of breath, and in severe cases, can stop the lungs from working completely. 4. Facilitates excretion of sodium and water while sparing potassium. Certain antibiotics. Your body needs potassium to function correctly. 2. All rights reserved. Consider switching to a potassium-sparing diuretic. There are subsets of patients that are susceptible to the development of hypokalemia. Common concentrations are 20 mEq/100 ml over 1 hour or 40 mEq/100 ml over 2 hours. Gastric fluid contains little amount of potassium. Infuse potassium-based medication or solutions slowly.Prevents administration of concentrated bolus, allows time for kidneys to clear excess free potassium. Adjust the IV potassium dose and rate depending on the available IV access. A more practical approach is calculation of the urine potassium-to-creatinine ratio from a spot urine specimen; a ratio greater than 1.5 mEq per mmol (13 mEq per g) is indicative of renal potassium wasting.18 If no cause is identified with the initial workup, assessment of thyroid and adrenal function should be considered. When he started to feel heart palpitations and shortness of breath, he decided to come to the hospital. Common acute manifestations are muscle weakness and ECG changes. Typically, 10 units of insulin are administered, followed by 25 g of glucose to prevent hypoglycemia.37 Because hypoglycemia is a common adverse effect even with the provision of glucose, serum glucose levels should be monitored regularly. knowing that the patient has hypokalemia and, specifically, periodic paralysis because of hypokalemia is only a beginning. Other diagnostic tests that may be performed are as follows: Potassium replacement. 3. (2015 Nov 22). Potassium helps in utilizing carbohydrates and protein to produce energy. 1. See permissionsforcopyrightquestions and/or permission requests. Therefore, although ECG changes should trigger urgent treatment, treatment decisions should not be based solely on the presence or absence of ECG changes.32, Peaked T waves are the prototypical, and generally the earliest, ECG sign of hyperkalemia. Short-term goal: By the end of the shift the patient will be able to list a few foods high in potassium. The ECG can provide useful information for hypokalemia. Inhibits renal potassium excretion, can ameliorate some of the hypokalemia that thiazide and loop diuretics can cause. Conditions that cause hypoaldosteronism, such as adrenal insufficiency and hyporeninemic hypoaldosteronism (a common complication of diabetic nephropathy and tubulointerstitial diseases), can lead to hyperkalemia. Hypokalemia | NEJM - New England Journal of Medicine do you see all the information i began to generate from those two pieces of information? More prolonged and profound hypokalemia may cause rhabdomyolysis, renal abnormalities, and cardiac arrhythmias. We may earn a small commission from your purchase. When severe, potassium disorders can lead to life-threatening cardiac conduction disturbances and neuromuscular dysfunction. Potassium is an electrolyte needed primarily for muscle and nerve tissue function. Assess urine output and kidney function through BUN, GFR, and creatinine levels. Hypokalemia (decreased potassium in the bloodstream) is commonly caused by vomiting, diarrhea, excessive sweating, or renal (kidney) disorder. Potassium movement from extracellular to intracellular fluid due to: IV therapy with potassium-deficient solutions, Rapid infusion of potassium-containing IV solutions, Adrenal insufficiency (such as in Addisons disease), Potassium movement from intracellular to the extracellular fluid, Muscle weakness, leg cramps, deep tendon hyporeflexia, and paresthesias, ECG changes: ST depression, inverted T waves, and prominent U waves, Increased motility, hyperactive bowel sounds, and diarrhea, Ascending flaccid paralysis until the respiratory muscles become affected as a toxic level of serum potassium is reached, ECG changes: Tall peaked T waves, widened QRS complexes, and prolonged PR intervals, Conditions that affect the movement of potassium in the cellular space, Alterations in the electrical conductivity of the heart, Patient will demonstrate serum potassium levels within normal limits, Patient will verbalize the absence of muscle pain or cramping, Disruption in the electric functioning of the heart, Patient will display pulse and blood pressure within acceptable limits, Patient will verbalize the absence of angina or palpitations, Patient will demonstrate ECG results of normal sinus rhythm, Patient will be able to verbalize understanding of decreased cardiac output in relation to hypo/hyperkalemia, Patient will participate in physical therapy sessions, Patient will be able to maintain or regain muscle strength. Also, large amounts of potassium found in the intestinal fluids are excreted during episodes of diarrhea. Figure 3 is an algorithm for the management of hyperkalemia, and Table 322,30,36 summarizes medications used in the treatment of the condition. This includes the heart muscle wherein when the potassium level is depleted abnormal heart waves are formed. Organ system dysfunction, such as life-threatening dysrhythmias, can occur when potassium is not balanced. Medication intake. Hypokalemia may result from inadequate potassium intake, increased potassium excretion, or . [] Hypokalemia is a potentially life-threatening imbalance that may be iatrogenically induced. Hypokalemia Treatment & Management - Medscape The effect can cause slow peristalsis which can lead to constipation. Wound Care & Infection Nursing Diagnosis & Care Plan, Parkinsons Disease Nursing Diagnosis & Care Plan, Hypokalemia serum potassium level < 3.5 mEq/L (3.5 mmol/L), Hyperkalemia serum potassium level > 5.0 mEq/L (5.0 mmol/L), Excessive use of potassium-wasting diuretics, Increased production of aldosterone (water and salt regulating hormone) (such as in Cushings syndrome), Kidney disease impairing the reabsorption of potassium, Poor potassium intake such as through eating disorders. Search dates: February, September, and December 2014. Place the patient on high potassium diet as per the physicians order. document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); This site uses Akismet to reduce spam. Bananas, oranges, apricots, cooked spinach, potatoes, and mushrooms are all high in potassium. Read theprivacy policyandterms and conditions. Potassium supplementation is the main treatment for hypokalemia. Peripherally potassium should be administered no faster than 10 mEq per hour. Although hypokalemia can be transiently induced by the entry of potassium into the cells, most cases result from unreplenished gastrointestinal or urinary losses due, for example, to vomiting, diarrhea, or diuretic therapy []. It is appropriate to increase dietary potassium in patients with low-normal and mild hypokalemia, particularly in those with a history of hypertension or heart disease.15 The effectiveness of increased dietary potassium is limited, however, because most of the potassium contained in foods is coupled with phosphate, whereas most cases of hypokalemia involve chloride depletion and respond best to supplemental potassium chloride.6,15, Because use of intravenous potassium increases the risk of hyperkalemia and can cause pain and phlebitis, intravenous potassium should be reserved for patients with severe hypokalemia, hypokalemic ECG changes, or physical signs or symptoms of hypokalemia, or for those unable to tolerate the oral form. Risk for falls associated with potassium imbalance is caused by a disruption in the electric signals in muscles resulting in muscle weakness, cramping, hyporeflexia, and paralysis. Hyperkalemia secondary to decreased distal delivery of sodium and water occurs with congestive heart failure, cirrhosis, acute kidney injury, and advanced chronic kidney disease. If administering IV, infuse secondarily to a compatible IV solution such as 0.9% normal saline to minimize burning at the IV site. Intravenous calcium, which helps prevent life-threatening conduction disturbances by stabilizing the cardiac muscle cell membrane, should be administered if ECG changes are present.24,25,35 Intravenous calcium has no effect on plasma potassium concentration. However, a 2014 study suggests that severe hypokalemia is rare. There are different types of test and diagnosis for hypokalemia disease, those are given in the below: S. Electrolytes / Potassium, Magnesium, Calcium, Phosphorous, TSH, Aldosterone, ECG, . Intravenous calcium should be administered if hyperkalemic ECG changes are present. 7. Review drug regimen for medications containing potassium or affecting potassium excretion such as spironolactone (Aldactone), hydrochlorothiazide (Maxzide), amiloride (Midamor), and penicillin G.Requires regular monitoring of potassium levels and may require alternate drug choices or changes in the dosage or frequency.
