Final answer:
Seizures are the clinical manifestation associated with hypernatremia in burns due to the elevated sodium levels that can affect the brain and cause neurological symptoms.
Step-by-step explanation:
The clinical manifestation associated with hypernatremia in burns is seizures. Hypernatremia refers to a high concentration of sodium in the blood, which can occur in various clinical situations, including those involving burns. Burns can lead to a loss of fluids and an increase in sodium concentration. High levels of sodium in the brain can lead to neurological symptoms, with seizures being one of the potential severe outcomes.
Other symptoms of hypernatremia, not specifically related to burns but worth considering, include fatigue, muscular weakness, and neurological issues. However, the direct manifestation related to burns and high sodium levels is the heightened risk of seizures.
