Registered Practical Nurse (RPN) Practice Test

When a client with schizophrenia switches the topic of conversation abruptly, failing to return to previous subjects, this is known as what?

1. Disorganized thinking

2. Tangentiality

3. Flight of ideas

4. Blocking

The correct answer is: Tangentiality

The term that describes a client who switches the topic of conversation abruptly and does not return to previous subjects is called tangentiality. This behavior is characterized by a pattern of speech where the individual moves from one topic to another in a way that is loosely related or not related at all, failing to address the original point of conversation. In clinical practice, this can be observed in individuals with schizophrenia, where the logical flow of thought is disrupted. Tangentiality differs from other forms of disorganized thinking, as it specifically pertains to the topics of conversation rather than the overall coherence of the narrative. It highlights a disconnection in the thought process that prevents the person from staying on topic. In contrast, other options like disorganized thinking can encompass broader issues beyond just conversational shifts, while flight of ideas reflects rapid shifting between multiple ideas but often maintains some logical connection between them. Blocking involves an abrupt interruption in train of thought, which is distinct from the gradual drifting seen in tangentiality.
