For a risk assessment for harm to self or others, it is essential to consider several different factors, including the presence of psychiatric symptoms, the patient's social support, and their history of self-harm or violence. A strong support system can be protective, while the absence of a previous suicide attempt may not necessarily indicate low risk.
Feelings of hopelessness have been consistently identified as a significant risk factor for suicide. The PMHNP should take the patient's reported feelings of hopelessness into account when assessing their risk of harm to themselves or others. Additionally, substance use, including the use of alcohol, can also increase the risk of harm and should be taken into account when conducting a risk assessment. Alcohol use, however, should not be conflated with alcohol abuse.

Cholinesterase inhibitors are used to treat dementia-related symptoms such as memory loss, confusion, and behavioral issues. These medications work by increasing levels of acetylcholine, a neurotransmitter involved in brain learning and memory processes. By increasing acetylcholine levels, cholinesterase inhibitors can help improve cognitive function and slow the progression of dementia-related symptoms.
Antidepressants may be used to treat depression, a common co-occurring condition in individuals with dementia, but are not typically used as the primary medication to treat dementia-related symptoms. Benzodiazepines are commonly used as anxiolytics and hypnotics, but they are not effective in treating dementia-related symptoms and may even worsen cognitive function in individuals with dementia. Antipsychotics may be used to treat behavioral symptoms in individuals with dementia, such as aggression or agitation, but they are not effective in treating cognitive symptoms associated with dementia.

The correct medical term for chronic nail biting is onychophagia. This term is derived from the Greek words "onycho", meaning nail, and "phagia", meaning eating. Onychophagia is classified as a type of body-focused repetitive behavior (BFRB), similar to behaviors such as hair pulling (trichotillomania) and skin picking (excoriation disorder).
Onychophagia is often considered a self-soothing behavior that people may engage in when they are feeling stressed, anxious, or bored. The habit typically begins in childhood, and it is observed that many children outgrow this behavior as they reach adulthood. Nevertheless, for some individuals, nail biting can persist into adult life and become a chronic issue.
Chronic nail biting can have several negative effects on a person's health. It can lead to physical damage to the nails and surrounding skin, increasing the risk of infections. Additionally, it can have dental repercussions, such as damage to the tooth enamel or misalignment of teeth. From a psychological perspective, severe onychophagia can be associated with feelings of shame or embarrassment, which may further exacerbate stress and anxiety, creating a vicious cycle.
Treatment for onychophagia often involves behavioral therapies, such as habit reversal training, which focuses on helping the individual identify triggers for nail biting and developing alternative coping mechanisms. In some cases, cognitive-behavioral therapy (CBT) may also be recommended to address underlying emotional issues contributing to the behavior. Sometimes, the use of bitter-tasting nail coatings can also serve as a deterrent from nail biting.
In conclusion, onychophagia, or chronic nail biting, is a common but manageable condition. Recognizing it as a psychological and physical health issue is crucial in seeking appropriate treatment and coping strategies. Individuals struggling with this condition are encouraged to seek help from healthcare professionals specialized in treating BFRBs.

Obsessive-compulsive falls under Cluster C.
Personality disorders are chronically maladaptive patterns of behavior that result in functional impairment in work, school, or relationships. The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders Fifth Edition defines 10 specific personality disorders divided into three clusters: Cluster A, Cluster B, and Cluster C.
Cluster A patients are characterized as withdrawn, cold, suspicious, and irrational. Cluster A includes paranoid, schizoid, and schizotypal personality disorders.
Cluster B patients are characterized as theatrical, emotional, and attention-seeking. They often experience intense interpersonal conflicts and exhibit an extremely labile mood. Cluster B includes antisocial, borderline, histrionic, and narcissistic personality disorders.
* Antisocial personality disorder: These patients exhibit criminal behavior beginning in childhood such as truancy, fighting, destructiveness, and theft. They often default on debts, behave irresponsibly, and act recklessly. They show no remorse for their behavior.
* Borderline personality disorder: These patients exhibit impulsivity, self-harm, inappropriate anger, and affective instability. They feel empty and bored, and they frantically try to avoid abandonment.
* Histrionic personality disorder: These patients appear overly emotional, vague, and desperate for attention, and they demand constant reassurance about their attractiveness.
* Narcissistic personality disorder: These patients act self-important and are preoccupied with envy, fantasies of success, and ruminations about the uniqueness of their problems. They reject criticism and need constant admiration from others.
Cluster C patients tend to be anxious, fearful, tense, and overcontrolled. Cluster C includes avoidant, dependent, and obsessive-compulsive personality disorders.

There are three phases of a therapeutic relationship between a nurse practitioner and a patient:
1. Introduction
2. Working
3. Termination
During the working phase, the following actions usually take place:
* Clarifying patient expectations and mutually identifying goals
* Implementing the treatment plan
* Monitoring the patient's health
* Undertaking preventative health care
* Measuring outcomes of care
* Evaluating outcomes of care
* Reprioritizing plan and objectives as indicated
Establishing professional boundaries and creating a trusting environment typically take place in the introduction phase. Developing a long-term plan of care that the patient can follow to maintain their well-being occurs in the termination phase.
