Free BCEN Certified Emergency Nurse (CEN) Practice Question
In the assessment of a patient with suspected high-voltage electrical injury, which clinical manifestation is indicative of severe internal tissue damage?
The correct answer is 'Muscle weakness and paralysis,' which can indicate deep tissue damage and neuromuscular effects that are not immediately visible. 'Localized erythema' is a sign of superficial damage but does not necessarily reflect the severity of deep tissues. 'Singed hair' may occur but does not specifically indicate underlying tissue injury. 'Superficial blistering' can arise from thermal injuries, yet does not reveal the extent of internal damage that might occur with electrical injuries.
