1. Describe the nature, purpose, and process of the mental status examination. 2. Examine the observations and clinical implications of each category of the mental status examination. 3. Identify commonly used psychological tests. 4. Analyze the value of using behavioral rating scales in psychiatric nursing practice. The mental status examination is a cornerstone in the evaluation of any patient with a medical, neurological, or psychiatric disorder that affects thought, emotion, or behavior (American Psychiatric Association, 2006). It is used to detect changes in a person’s intellectual functioning, thought content, judgment, mood, and affect. The mental status examination is to psychiatric nursing what the physical examination is to general medical nursing. The mental status examination includes information in a number of categories (Box 6-1). It is one part of a complete psychiatric nursing assessment tool. In completing this examination, it is critically important to be aware that sociocultural factors can greatly influence the outcome of the examination (Box 6-2). The content, observations, and some of the clinical implications associated with each category are described in the following sections (Robinson, 2002). • Speech disturbances are often caused by specific brain disturbances. For example, mumbling may occur in patients with Huntington chorea, and slurring of speech may occur in intoxicated patients. • Manic patients often show pressured speech. • People with depression often are reluctant to speak at all. Motor activity describes the patient’s physical movement. • Excessive body movement may be associated with anxiety, mania, or stimulant abuse. • Little body activity may suggest depression, organic mental disorders, catatonic schizophrenia, or drug-induced stupor. • Tics and grimaces may suggest medication side effects. • Repeated motor movements or compulsive behavior may indicate obsessive-compulsive disorder. • Repeated picking of lint or dirt off of clothing is sometimes associated with delirium or toxic conditions. Interaction describes how the patient relates to the nurse during the interview. Because this part of the examination relies heavily on nurses’ emotional subjectivity, nurses must carefully examine their responses based on their own personal and sociocultural biases. They must guard against overinterpreting or misinterpreting patients’ behavior because of social or cultural differences between patients and nurses (Chapter 7). If the potential for suicide is suspected, the nurse should ask the patient directly about thoughts of self-harm (Chapter 19). Has the patient felt the desire to harm himself or someone else? Have any previous attempts been made to cause harm, and if so, what events surrounded the attempts? To judge a patient’s suicidal or homicidal risk, the nurse should assess the patient’s plans, the patient’s ability to carry out those plans (e.g., the availability of guns), the patient’s attitude about death, and support systems available to the patient.
