Nursing Care Plan: Patient with Electrical Shock Injury
Priority: Treat as a trauma and cardiac emergency. Ensure the electrical source is off before touching the patient. Activate emergency response immediately if the patient is unconscious, has chest pain, breathing difficulty, severe burns, or abnormal pulse.
Electrical injuries may produce hidden deep-tissue damage, arrhythmias, respiratory arrest, rhabdomyolysis, and burns even when the visible skin injury appears small. Low-frequency household AC can cause muscle tetany and ventricular fibrillation. Tintinalli's Emergency Medicine, p. 1438.
Assessment
Subjective data
- Pain or burning sensation
- Chest pain, palpitations
- Dizziness, headache, weakness
- Numbness, tingling, reduced movement
- History of loss of consciousness
- Details of exposure: household versus industrial source, wet environment, duration, entry and exit points
Objective data
- Level of consciousness, GCS, pupils
- Airway patency, respiratory rate, oxygen saturation, breath sounds
- Heart rate, rhythm, BP, peripheral pulses, capillary refill
- ECG findings
- Skin: entry/exit wounds, extent and depth of burns, color, edema, blistering
- Musculoskeletal trauma from fall or violent muscle contraction
- Urine output and color, especially dark or tea-colored urine suggesting myoglobinuria
- Labs as ordered: CBC, electrolytes, creatinine, CK, urinalysis for myoglobin, cardiac tests when clinically indicated
1. Nursing Diagnosis: Ineffective Tissue Perfusion - Cardiac
Related to: electrical-current effect on cardiac conduction and possible dysrhythmias
Evidenced by: abnormal ECG/rhythm, palpitations, chest pain, hypotension, poor peripheral perfusion, or syncope.
Goals/Expected outcomes
- Patient maintains stable HR, BP, oxygen saturation, and level of consciousness.
- ECG remains normal or dysrhythmia is identified and treated promptly.
- Patient reports no chest pain or palpitations.
Nursing interventions and rationale
| Interventions | Rationale |
|---|
| Assess ABCs immediately; call emergency/rapid response team for instability. | Electrical injury can cause sudden respiratory or cardiac arrest. |
| Monitor vital signs, peripheral pulses, skin color, capillary refill, and mental status frequently. | Detects early deterioration in circulation and oxygen delivery. |
| Obtain a 12-lead ECG and initiate continuous cardiac monitoring as ordered. | Electrical current can disrupt cardiac conduction and cause arrhythmias. |
| Observe for chest pain, palpitations, syncope, dyspnea, or ECG changes; report immediately. | These findings may signal cardiac injury requiring urgent evaluation. |
| Maintain IV access and administer oxygen, IV fluids, and prescribed medications as ordered. | Supports oxygenation, circulation, and emergency treatment if needed. |
| Prepare for ACLS measures/defibrillation if pulseless rhythm develops. | Ventricular fibrillation or arrest can occur after significant electrical exposure. |
| Document voltage source, AC/DC type if known, contact duration, pathway through body, and loss of consciousness. | Exposure characteristics help estimate cardiac and tissue-injury risk. |
Evaluation: Patient has stable vital signs, adequate peripheral perfusion, no chest pain/palpitations, and no clinically significant dysrhythmia.
An ECG is recommended at initial assessment. Longer monitoring is indicated with chest pain, abnormal ECG, transthoracic current path, cardiac arrest, loss of consciousness, or cardiac history, according to
StatPearls guidance.
2. Nursing Diagnosis: Impaired Skin Integrity
Related to: thermal and deep-tissue injury from electrical current
Evidenced by: entry/exit wounds, burns, blistering, edema, necrosis, or tissue destruction.
Goals/Expected outcomes
- Burn wounds remain clean and free of infection.
- No increase in burn depth, edema, or tissue necrosis occurs.
- Patient demonstrates correct wound-care instructions before discharge.
Nursing interventions and rationale
| Interventions | Rationale |
|---|
| Inspect and document location, size, depth, color, drainage, odor, and possible entry/exit sites. | Electrical burns may have limited surface injury but severe deeper muscle and tissue damage. |
| Remove jewelry and constricting items near injured areas, if safe and appropriate. | Prevents pressure injury as edema develops. |
| Cover burns with clean, dry sterile dressing as ordered. Do not apply ice, ointment, or adhesive material unless prescribed. | Protects tissue and decreases contamination while avoiding further injury. |
| Perform wound care with aseptic technique; monitor for redness, purulent drainage, fever, or worsening pain. | Damaged skin increases infection risk. |
| Assess distal circulation, sensation, movement, pain, and swelling in affected limbs. | Helps detect neurovascular compromise and possible compartment syndrome. |
| Administer tetanus prophylaxis and prescribed topical/systemic therapy. | Electrical burns require tetanus protection and burn management. |
| Refer or prepare transfer to a burn/trauma unit for high-voltage injury, deep burns, circumferential burns, or significant tissue destruction. | These injuries may require surgical assessment, fasciotomy, debridement, or specialized burn care. |
Evaluation: Wounds are protected, no signs of infection or compromised circulation are present, and patient/family understands wound care.
3. Nursing Diagnosis: Acute Pain
Related to: electrical burns, tissue damage, muscle injury, and procedures
Evidenced by: verbal report of pain, guarding, facial grimacing, restlessness, or increased HR/BP.
Goals/Expected outcomes
- Patient reports pain at a tolerable level, for example ≤3/10.
- Patient appears relaxed and can rest or participate in care.
- Vital signs remain near baseline.
Nursing interventions and rationale
| Interventions | Rationale |
|---|
| Assess pain regularly using a valid scale and reassess after interventions. | Establishes baseline and determines response to treatment. |
| Assess pain location, character, severity, and whether it is increasing disproportionately. | Severe increasing pain may indicate deeper tissue injury or compartment syndrome. |
| Administer prescribed analgesics, including IV analgesia for severe burns, and monitor effect/adverse effects. | Electrical burns can cause severe pain requiring prompt treatment. |
| Elevate injured extremity if prescribed and circulation is intact. | May reduce edema and discomfort. |
| Use non-drug measures: calm environment, positioning, explanation before procedures, relaxation breathing. | Reduces anxiety and supports pain relief. |
Evaluation: Pain is controlled, patient is able to rest, and no disproportionate pain or neurovascular deterioration is present.
4. Nursing Diagnosis: Risk for Ineffective Renal Perfusion / Acute Kidney Injury
Risk factors: muscle injury, rhabdomyolysis, hemoglobin/myoglobin release, dehydration, extensive electrical burns.
Goals/Expected outcomes
- Urine output remains adequate and urine does not become dark.
- Renal function and electrolytes remain within acceptable range.
- Patient has no signs of fluid overload or acute kidney injury.
Nursing interventions and rationale
| Interventions | Rationale |
|---|
| Measure strict intake and output; monitor hourly urine output in significant injury. | Adequate urine output indicates renal perfusion and assists clearance of myoglobin. |
| Observe urine for dark brown/tea color and report it promptly. | May indicate myoglobinuria due to rhabdomyolysis. |
| Monitor CK, potassium, creatinine, BUN, urinalysis, and ECG as ordered. | Muscle breakdown may cause hyperkalemia and acute kidney injury. |
| Administer IV fluids as prescribed and assess lung sounds, edema, BP, and urine response. | Fluids help maintain renal perfusion and dilute myoglobin, but must be balanced against fluid overload. |
| Avoid nephrotoxic medications where possible and report declining urine output. | Reduces additional renal stress. |
Evaluation: Urine output is adequate, urine is clear/light yellow, CK/renal tests are monitored, and there is no evidence of AKI.
For severe electrical injury, fluids are titrated to urine output because standard surface-burn formulas can underestimate fluid needs; myoglobinuria requires close renal monitoring, as summarized in the
Merck Manual review.
5. Nursing Diagnosis: Anxiety
Related to: sudden traumatic event, fear of death/disability, unfamiliar environment, and painful procedures
Evidenced by: verbalized fear, restlessness, insomnia, crying, repeated questions, tachycardia.
Goals/Expected outcomes
- Patient verbalizes reduced anxiety.
- Patient demonstrates understanding of treatments and monitoring.
- Patient participates in care decisions as able.
Nursing interventions and rationale
- Stay with the patient during acute phase and communicate calmly.
- Give short, clear explanations of procedures and monitoring.
- Encourage expression of fears and questions.
- Involve family/support person when appropriate.
- Teach warning signs to report: chest pain, palpitations, breathing difficulty, weakness, worsening pain, reduced sensation, dark urine, fever, or wound drainage.
- Arrange psychological support or follow-up if anxiety, sleep disturbance, or trauma symptoms persist.
Evaluation: Patient verbalizes understanding, appears calmer, and asks appropriate questions.
Discharge Teaching
Discharge should only occur after medical assessment confirms it is safe. The patient should:
- Keep burn dressings clean and dry as instructed.
- Take prescribed pain medicines and complete wound-care plan.
- Avoid returning to electrical work or hazardous exposure until medically cleared.
- Seek emergency care immediately for chest pain, palpitations, fainting, shortness of breath, confusion, worsening weakness, dark urine, fever, wound redness, pus, increasing swelling, or severe pain.
- Attend burn, surgical, cardiac, neurologic, and rehabilitation follow-up as advised.
A patient who is asymptomatic after a brief household-current exposure, with normal examination and ECG and no cardiac risk factors, may sometimes need no extended monitoring; this decision must be made by the treating clinician.
Merck's electrical-injury guidance also recommends tetanus prophylaxis for electrical burns and specialist burn referral for significant burns.
