Nurse Hazel is caring for a male client who experiences false sensory perceptions with no basis in reality. This perception is known as:

Correct Answer: A. Hallucinations

Hallucinations are visual, auditory, gustatory, tactile or olfactory perceptions that have no basis in reality. The word “hallucination” comes from Latin and means “to wander mentally.” Hallucinations are defined as the “perception of a nonexistent object or event” and “sensory experiences that are not caused by stimulation of the relevant sensory organs.” Hallucinations occur frequently in people with psychiatric conditions, including schizophrenia and bipolar disorder, however, you don’t necessarily need to have a mental illness to experience hallucinations.

• Option B: Delusions are defined as fixed, false beliefs that conflict with reality. Despite contrary evidence, a person in a delusional state can’t let go of their convictions. Delusions are often reinforced by the misinterpretation of events. Many delusions also involve some level of paranoia. For example, someone might contend that the government is controlling our every move via radio waves despite evidence to the contrary.
• Option C: A thought disturbance demonstrated by speech that is disconnected and fragmented, with the individual jumping from one idea to another unrelated or indirectly related idea. It is essentially equivalent to derailment.
• Option D: In psychiatry, the term is used to describe the creation of words which only have meaning to the person who uses them. It is considered normal in children, but a symptom of thought disorder indicative of a psychotic mental illness such as schizophrenia in adults. Usage of neologisms may also be related to aphasia acquired after brain damage resulting from a stroke or head injury.
