What are the categories for delirium?

A. The term “hypo-reflexive” is not used in delirium classification. While hyperactive and mixed forms exist, the correct terminology for the reduced activity type is “hypoactive,” not hypo-reflexive. Mislabeling can lead to under-recognition of hypoactive delirium, which is often missed because patients appear quiet or lethargic. B. Delirium is commonly classified into three subtypes. Hyperactive delirium is characterized by agitation, restlessness, rapid speech, irritability, and sometimes hallucinations. Patients may pull at lines or exhibit aggressive behavior. Hypoactive delirium is characterized by lethargy, decreased responsiveness, slowed speech, and withdrawal. This subtype is often underdiagnosed because patients are quiet and less disruptive. Mixed delirium occurs when patients fluctuate between hyperactive and hypoactive states. This is the most common form in hospitalized patients and can make recognition and management challenging. Understanding these subtypes helps nurses monitor for subtle changes, tailor interventions, and prevent complications like falls, self-harm, or delayed recovery. C. These terms are unrelated to delirium classification. “Hypertensive” refers to high blood pressure, and “sedated” refers to medication-induced CNS depression; neither defines delirium subtypes. D. “Hyper-reflexive” is not a recognized category of delirium. While hypoactive is correct for one subtype, “sedated” is not a delirium type but a treatment-related state. Using incorrect terminology could lead to misdiagnosis and inappropriate interventions.
