The target lab value for sodium is 135-146 mEq/L, which falls within the normal physiological range for serum sodium levels. Sodium is a critical electrolyte in the body that helps regulate fluid balance, blood pressure, and is vital for proper nerve and muscle function. Maintaining sodium levels within this range is essential for homeostasis and can help prevent complications such as dehydration, electrolyte imbalances, and cardiovascular issues.

Values outside of the range can indicate different conditions—hypoatremia (low sodium) or hypernatremia (high sodium)—both of which can lead to serious health problems if not addressed appropriately. Therefore, the specified target range reflects the levels necessary for optimal bodily function, making it the correct answer in this context.
