If not treated promptly and correctly, some imbalanced electrolytes have life-threatening consequences and can even lead to cardiac arrest.
When electrolytes become imbalanced, they can impair many of the body's critical functions, including blood acidity and pressure regulation, hydration levels, nerve and muscle coordination, and tissue repair. Losing body fluids caused by diarrhea, sweating, vomiting, medications, conditions, or extensive burns often lead to electrolyte imbalances that must be treated medically and with a nursing care plan for hands-on care and nursing interventions.
This article offers ten electrolyte imbalance nursing diagnoses and care plans to help you care for your patients. We'll focus on acid-base, sodium, calcium, magnesium, and potassium imbalances.
Signs and Symptoms of Electrolyte Imbalance
Different types of electrolyte imbalances cause various signs and symptoms. The signs depend on which electrolyte is affected, the severity of the imbalance, and the presence of comorbidities. However, there are common signs you might observe with most types of imbalances. Many patients experience no noticeable symptoms if the imbalance is mild or occurs gradually.
Common signs and symptoms of electrolyte imbalance include:
Assessment of Electrolyte Imbalance
The nursing assessment is vital to the identification of electrolyte imbalances. Registered nurses or practical nurses must take a comprehensive history and perform a physical exam, paying particular attention to the patient's skin turgor to assess for dehydration. In addition, you should ask about any recent changes in medication and inquire about the patient's dietary habits.
It is also vital to obtain laboratory tests for electrolytes such as sodium, potassium, chloride, and bicarbonate. Abnormal electrolyte levels should be promptly reported to the healthcare provider so treatment can begin.
Factors Affecting the Occurrence of Electrolyte Imbalance
Many factors can lead to electrolyte imbalance, including:
Causes of Electrolyte Imbalance
More than half of the body's weight consists of water. Blood and fluid in and around the cells hold most of the water found in the body. In addition, electrolytes move throughout the body due to the function of the liver, kidneys, and other organs. Because electrolytes are needed for overall health and wellness, many changes in the body or organ function can create imbalances that require treatment.
The most common causes of electrolyte imbalance include:
Treatments
However, if the imbalance is severe or related to an acute medical condition, surgery, or trauma, the patient may need hospitalization and treatment with IV fluids and other medications. In addition, patients with kidney failure or severe kidney damage may require hemodialysis to remove waste and fluids from the body to achieve electrolyte balance.
Complications
Untreated or significant electrolyte imbalances can be life-threatening and cause the following complications:
Nurse's Role Caring for a Patient with Electrolyte ImbalanceNurses are integral in caring for acutely ill patients experiencing an electrolyte imbalance. Thorough head-to-toe assessments to check for new or worsening signs of specific imbalances and monitoring and reporting any critical lab values ensure that changes in the patient's condition are addressed quickly.
In the home or outpatient setting, nurses perform similar assessments for signs and symptoms of electrolyte imbalances. In addition, medication and condition education is essential to the long-term management of any imbalances and the underlying conditions that cause them. Teaching patients self-care strategies can prevent acute exacerbations and hospitalizations.
Nursing Protocols for Electrolyte Imbalance
Nurses must know the protocols for electrolyte imbalance. They must recognize the signs of each type of imbalance, evaluate and monitor electrolyte levels, and create individualized nursing care plans to address their findings. They should also be familiar with treatments for electrolyte imbalances, like rehydration therapy and medications.
Each protocol starts with assessing the patient's symptoms with planned interventions and desired outcomes.
Nurses treating a patient for electrolyte imbalances will perform the following tasks to ensure the patient's safety and well-being:
Nursing Care Plans Related to Electrolyte ImbalanceNow, let's review some nursing care plans you can use when caring for patients with common electrolyte imbalances. The below nursing care plans are not exhaustive or individualized to a patient but can provide an overview of how to address these conditions.
It's also important to note that lab values are not included in these nursing care plans as each laboratory establishes normal and abnormal values. Therefore, always refer to your institution's laboratory value norms and protocols when determining when to report electrolyte imbalance values to the healthcare provider.

Rationale: Increases urinary flow and removal of calcium to minimize the risk of stone formation and improves hydration.
Rationale: Increases urinary excretion by diluting extracellular calcium concentrations and reducing tubular reabsorption of calcium.
Risk for Hypocalcemia Care PlanHypocalcemia occurs when calcium levels in the blood are abnormally low. Chronic laxative use, diarrhea, and certain medications can cause hypocalcemia. Low calcium levels can disrupt the body's magnesium and phosphorous levels, causing an electrolyte imbalance.

Risk for Hypermagnesemia Care PlanMagnesium regulation happens in the renal and gastrointestinal systems. The nutrient is absorbed in the GI tract and excreted through urine. If an excess of magnesium exists, it's stored in the bones.
Hypermagnesemia happens when magnesium levels in the blood are abnormally high. Magnesium is a vital nutrient in the body and is needed to maintain nerve and muscle function, blood pressure, and blood glucose levels.

Risk for Hyperkalemia Care PlanPotassium is critical to normal body function, including the operation of the heart, kidneys, muscles, and nervous system. In addition, this essential macromineral regulates the osmolarity of extracellular fluid by exchanging it with sodium. It also helps to keep the transmembrane electrical potential between the intracellular and extracellular fluid within normal limits.
Hyperkalemia happens when the potassium levels in the blood are abnormally high. This condition is common in patients with abnormal kidney function affecting the ability to remove potassium from the body, such as in patients with renal disease. In addition, other treatment modalities can affect the potassium levels in the body and place the patient at an elevated risk of hyperkalemia.

Rationale: Reduces muscle weakness and cramping and improves muscle tone.
Risk for Hypokalemia Care PlanHypokalemia is when the potassium levels in the blood are abnormally low, which can cause serious problems such as muscle weakness, paralysis, and cardiac arrest.
