Wisconsin CNA State Exam Vocabulary Practice

The correct choice is "emotional lability." This term specifically refers to rapid and often extreme changes in emotional expression, such as uncontrollable laughing or crying. It is commonly associated with certain neurological or psychological conditions where an individual's emotional responses can be disproportionate or erratic. This captures the essence of the phenomenon you are describing.

Emotional stress, while it may involve intense feelings, does not specifically refer to the sudden and uncontrollable shifts in emotion. Emotional support involves providing assistance and comfort to those experiencing emotional distress, and empathy is the ability to understand and share the feelings of another. Neither of these terms conveys the specific nature of the described behavior.
