質問 # 400
You are treating a 45-year-old patient who has been diagnosed with schizophrenia and treated with thioridazine (Mellaril) for the past 15 years. You decide to switch the patient to a different antipsychotic due to what serious long-term consequence that is specific to high-dose thioridazine?
- A. Hyperprolactinemia
- B. Priapism
- C. Tardive dyskinesia
- D. Retinal pigmentation
正解：D
解説：
Retinal pigmentation can occur in patients prescribed >1,000 mg of thioridazine. Even when thioridazine is stopped, this side effect may persist and lead to blindness.
Hyperprolactinemia, priapism, and tardive dyskinesia can occur as side effects of any antipsychotic medication.
質問 # 401
A patient asks if she can be tested for HIV. Before administering the test, what should the nurse practitioner do first?
- A. Call the patient's parents about the test
- B. Conduct a pregnancy test
- C. Inform the patient's sexual partners about their risk of HIV
- D. Explain to the patient the test and her privacy rights
正解：D
解説：
The first thing a nurse practitioner should do is obtain informed consent by explaining the test to the patient, including the risk of false positives and false negatives. If the patient tests positive for HIV, some states require the nurse practitioner to notify the patient's sexual partners.
Contacting the patient's parents or sexual partners prior to the test violates confidentiality.
質問 # 402
What type of complementary therapy consciously directs attention to alter one's state of consciousness?
- A. Meditation
- B. Massage
- C. Breathwork
- D. Yoga
正解：A
解説：
Meditation produces physiological effects (e.g., decreases in heart rate, blood pressure, respiratory rate, and anxiety). It also increases alpha brain waves.
Breathwork, massage, and yoga may all contribute to altered states of consciousness but do not consciously direct attention to this.
質問 # 403
Which of the following is least likely to play a role in the development of oppositional defiant disorder?
- A. Trauma
- B. Parents who model extreme ways of expressing emotions
- C. Unresolved conflicts
- D. Frequent relocation of residency
正解：D
解説：
Oppositional defiant disorder etiology has its foundation in the following situations:
* Temperament
* Parents who model extreme ways of expressing emotions
* Trauma
* Unresolved conflicts
質問 # 404
Who is typically granted unrestricted visitation rights with a patient who is psychiatrically hospitalized?
- A. First-degree relatives
- B. Anyone the patient specifies during their admission process
- C. The patient's attorney and members of the clergy
- D. Only those whom the nurse practitioner deems appropriate
正解：C
解説：
A patient has the right to receive visitors during reasonable hours while hospitalized. Unrestricted visitation rights are only granted to the patient's attorney and members of the clergy.
Neither the patient nor the nurse practitioner can determine who receives unrestricted visitation. If a visitor is turned away, the reason should be documented in the patient's chart (e.g., the visitor is bringing drugs onto the unit).
質問 # 405
A phenotype is the observable characteristic of a specific trait and is connected to the genetic contributions to that trait. Which of the following is an example of a phenotype associated with the fast metabolism of medications?
- A. Thymine
- B. CYP4502D6
- C. Adenine
- D. Cytosine
正解：B
解説：
A phenotype, not a genotype, is the observable characteristic of a specific trait and is connected to the genetic contributions to that trait. CYP4502D6 is an example of an expressed trait that contributes to the fast metabolism of medications.
Adenine, thymine, and cytosine are all nucleotide bases that make up a DNA strand.
質問 # 406
What does the term "sexual identity" typically describe?
- A. Sexual identity refers to a person's perception of self in relation to who they are romantically or sexually attracted to
- B. Sexual identity is a formal diagnosis to describe persons who experience gender dysphoria
- C. Sexual identity is an umbrella term describing people whose gender identity does not conform to gender norms associated with the sex they were assigned at birth
- D. Sexual identity refers to a person's perception of their masculinity or femininity
正解：A
解説：
Sexual identity is typically used to refer to one's perception of self in terms of attraction. Sexual orientation can also refer to the direction of sexual attraction; however, many people prefer the term sexual identity because it allows people to determine their own identities. Sexual orientation or identity is not always used in a way that relates to gender identity.
Gender identity is typically used to refer to a person's identity along a continuum between normative constructs of masculinity and femininity. Gender identity disorder is a formal diagnosis to describe persons who experience significant gender dysphoria. Transgender is typically used as an umbrella term describing people whose gender identity does not conform to gender norms associated with the sex they were assigned at birth.
質問 # 407
A PMHNP works in a community mental health clinic and evaluates a patient's competency to make decisions about their treatment. Which of the following best describes the concept of competency in mental health care?
- A. The ability to comply with treatment recommendations and follow through with prescribed medications
- B. The ability to make decisions that are in the best interest of the patient
- C. The ability to make decisions without interference from family or caregivers
- D. The ability to make informed decisions about treatment options
正解：D
解説：
Competency refers to patients' ability to make informed decisions about their treatment. It is based on the patient's capacity to understand the risks and benefits of treatment and their ability to communicate their preferences and make decisions that are consistent with their values and goals.
Competency is not the same as capacity, which refers to a patient's ability to make decisions at a specific moment in time (e.g., when under the influence of medication or experiencing acute symptoms).
質問 # 408
A 21-year-old male with no previous psychiatric history arrives at the emergency department accompanied by his girlfriend. She explains that for the past six weeks, he has been acting bizarrely by talking to people who are not present and suggesting the FBI is monitoring his behavior. His vital signs and neurological exam are normal.
What is the first test you order?
- A. Liver function test
- B. Urine drug screen
- C. CT scan of the brain
- D. Complete blood count
正解：B
解説：
This patient does not have a psychiatric history, and his symptoms have only lasted six weeks. Before diagnosing a psychiatric condition, you need to rule out the possibility that his symptoms are the effects of a substance. A urine drug screen is the first step to rule out a substance-induced psychotic disorder.
A CT scan of the brain might also be necessary but at a later time.
質問 # 409
A patient with bipolar disorder is prescribed aripiprazole (Abilify). What is the rationale for using this medication to treat bipolar disorder?
- A. Aripiprazole is a second-generation or atypical antipsychotic that can help prevent both manic and depressive episodes in patients with bipolar disorder
- B. Aripiprazole is an antidepressant medication that can treat the depressive symptoms of bipolar disorder
- C. Aripiprazole is an anxiolytic medication that can help manage the anxiety symptoms often associated with bipolar disorder
- D. Aripiprazole is an antipsychotic medication that can treat the hallucinations and delusions that may occur in bipolar disorder
正解：A
解説：
Abilify (aripiprazole) is classified as an atypical or second-generation antipsychotic medication. Atypical antipsychotics are a class of drugs that are primarily used to treat psychiatric conditions such as schizophrenia, bipolar disorder, and major depressive disorder. They are called "atypical" because they have a different pharmacological profile compared to older, typical antipsychotics.
Aripiprazole is an atypical antipsychotic medication that is effective in the treatment of bipolar disorder. It works by modulating the activity of dopamine and serotonin in the brain, which can help stabilize mood and prevent manic and depressive episodes.
質問 # 410
In the study of population genetics, most diseases are considered multifactorial and a combination of genetics and environmental factors. Which of the following is an example of a genetic influence?
- A. Abuse
- B. Poor nutrition
- C. Family history of disease
- D. Prenatal insults
正解：C
解説：
Most disease processes are multifactorial, meaning they are caused by both environmental and genetic factors. Single-gene disorders are rare. A family history of disease is most likely a genetic factor.
Environmental factors include prenatal insults, stress, infections, poor nutrition, exposure to toxins, catastrophic loss, or abuse.
質問 # 411
Increased levels of sodium can cause which of the following?
- A. Diuresis
- B. Renal disorders
- C. Hypovolemia
- D. GI fluid loss from vomiting and diarrhea
正解：C
解説：
Decreased, not increased, levels of sodium can cause diuresis, renal disorders, and gastrointestinal fluid loss from vomiting and diarrhea.
質問 # 412
A patient presents with symptoms of intellectual disability and physical characteristics such as a long face, large ears, and postpubertal macroorchidism. What is the most likely diagnosis for this patient?
- A. Fragile X syndrome (FXS)
- B. Turner syndrome
- C. Prader-Willi syndrome
- D. Down syndrome
正解：A
解説：
FXS, also known as Martin-Bell syndrome, is a genetic disorder caused by a mutation in the FMR1 gene on the X chromosome. It is the second most common inherited form of intellectual disability and affects about 1 in 1,000 males and 1 in 2,000 females. It is characterized by intellectual disability and physical characteristics such as a long face, large ears, and large testicles in males.
質問 # 413
Diagnosing mental illness is a process that includes a physical examination, lab tests, and psychological evaluation. If after going through this process the psychiatric mental health nurse practitioner finds that the patient has an alcohol problem that includes a lack of emotional and behavioral control, she knows that this falls into the class of mental illness known as:
- A. trauma-related disorders
- B. dissociative disorders
- C. disruptive, impulse-control, and conduct disorders
- D. somatic disorders
正解：C
解説：
Diagnosing mental illness involves a thorough process that includes several key steps. First, a physical examination is conducted to rule out any physical causes of symptoms. This is followed by laboratory tests that might highlight physiological factors influencing the mental state, such as thyroid function or vitamin deficiencies. Lastly, a psychological evaluation is performed which involves assessing the mental health symptoms, their history, and the impact on the individual's functioning.
When a psychiatric mental health nurse practitioner evaluates a patient, they consider all symptoms presented, including behavioral and emotional expressions. If the patient demonstrates a significant problem with alcohol that is associated with a lack of control over emotions and behaviors, this could indicate a specific category of mental disorders.
Disruptive, impulse-control, and conduct disorders are a class of mental health diagnoses that encompass these types of issues. These disorders are characterized by difficulties regulating emotions and behaviors, which significantly impair the individual's ability to function in social, educational, or occupational settings. The hallmark of these disorders is the inability to resist impulses, or the drive to perform actions that harm oneself or others.
Examples of such disorders include: - **Intermittent Explosive Disorder**: Where individuals have explosive outbursts of anger and violence that are disproportionate to the situation. - **Kleptomania**: Which involves a recurrent urge to steal, typically without necessity or monetary motivation. - **Conduct Disorder**: Noted among children and adolescents, this disorder is characterized by behavior that violates the rights of others, such as aggression towards people and animals, destruction of property, and deceitfulness or theft.
In the case of a patient with an alcohol problem displaying uncontrolled emotional and behavioral symptoms, the nurse practitioner might consider a diagnosis within this category. Alcohol can exacerbate or mimic the symptoms of these disorders, making careful evaluation critical. Treatment typically involves a combination of psychotherapy, medication, and in some cases, management of substance abuse issues, aiming to improve the individual's impulse control and overall emotional regulation.
Understanding the nuances of these disorders and the interplay with substance abuse like alcohol is crucial in providing effective care and support to patients struggling with these complex challenges.
質問 # 414
There are multiple etiological theories regarding the development of schizophrenia, ranging from psychological to neurobiological. The theory that intrauterine injury may contribute to the etiology of schizophrenia is an example of which type of etiological theory?
- A. Polygenic SNIP defect
- B. Neurodevelopmental
- C. Chromosome 6p24-22 defect
- D. Heredity
正解：B
解説：
An example of neurodevelopment etiology is intrauterine injuries, such as prenatal exposure to toxins, including viral agents; oxygen deprivation; maternal malnutrition; substance use; or other illnesses.
Polygenic SNIP defects, heredity, and chromosomal abnormalities are all examples of genetic etiologies.
質問 # 415
A psychiatric nurse practitioner is working with a patient who has been diagnosed with major depressive disorder. Which of the following health promotion and maintenance strategies would be most appropriate for this patient?
- A. Advising the patient to increase their intake of omega-3 fatty acids
- B. Encouraging the patient to start a regular exercise program
- C. Referring the patient to a therapist for cognitive-behavioral therapy
- D. Prescribing a new medication for the patient
正解：C
解説：
Cognitive-behavioral therapy (CBT) is a form of talk therapy that is effective in treating major depressive disorder. It helps patients identify and change negative thought patterns and behaviors contributing to their depression. A referral to a therapist for CBT would be the most appropriate health promotion and maintenance strategy for this patient, as it addresses the underlying cause of their depression and can help improve their overall mental health.
質問 # 416
Which of the following is least likely to be a reason for requesting lab work for an individual presenting with major depressive disorder (MDD)?
- A. Validate the diagnosis
- B. Rule out metabolic causes
- C. Assess thyroid function
- D. Test for vitamin B12 levels
正解：A
解説：
There have not been enough studies to support specific lab findings congruent with MDD. Common labwork orders include thyroid function studies, vitamin B12, folate, and a CBC to rule out any underlying medical or metabolic conditions.
質問 # 417
When is a nurse practitioner's scope of practice legally the most secure?
- A. When the scope of practice is defined by a physician who can delegate tasks to a nurse practitioner
- B. When the scope of practice is defined by a law prohibiting the practice of medicine without a license
- C. When the scope of practice is defined by a regulation
- D. When the scope of practice is defined by a statute
正解：D
解説：
A nurse practitioner's scope of practice is legally the most secure when it is clearly defined by a statute. Physicians' organizations often try to prevent nurse practitioners from providing patient care by pointing to state law and asking for a strict interpretation. When a nurse practitioner's scope of practice is clearly defined by statute, it is most secure against physician special interest groups.
質問 # 418
If evidence based practice suggests that a GPS can help keep track of patients with dementia and your unit spends time every day looking for patients who wander away from their rooms, what might be considered before implementing the program?
- A. Cost benefit analysis
- B. Anticipatory planning
- C. Resource stewardship
- D. Marketing
正解：A
解説：
**Resource Stewardship** Resource stewardship refers to the responsible management and use of resources. In a healthcare setting, this encompasses efficiently using resources such as time, staff, equipment, and technology to improve patient care while minimizing waste. When considering the implementation of a GPS tracking system for patients with dementia, it is crucial to evaluate whether this technology aligns with effective resource use. Does the program maximize patient safety and staff efficiency without excessively drawing on hospital resources? These questions relate to resource stewardship but are distinct from conducting a thorough cost benefit analysis, which quantifies these considerations in financial terms.
**Cost Benefit Analysis** The correct answer, cost benefit analysis, directly addresses the need to evaluate the financial implications of implementing a GPS system for dementia patients. This analysis involves calculating the total costs associated with the purchase, implementation, and ongoing maintenance of the GPS systems against the potential savings from reduced staff time spent searching for wandering patients, potential reduction in incidents or accidents involving patients, and possible improvement in regulatory compliance or patient satisfaction scores. The goal is to determine whether the financial benefits (savings and value created) exceed the costs incurred. If the benefits outweigh the costs, then it would be financially justifiable to proceed with the program.
**Marketing** Marketing considerations involve the promotion and communication strategies within and possibly outside the healthcare facility. For the GPS tracking system, marketing might involve internal campaigns to educate staff and patients' families about the new system and its benefits, thereby ensuring smooth adoption and optimal usage. While important for the success of the program, marketing does not directly address the financial analysis of costs versus benefits, which is central to the decision-making process in this scenario.
**Anticipatory Planning** Anticipatory planning involves preparing for future needs and potential scenarios to ensure sustainable operations. In the context of implementing a GPS system for patients with dementia, anticipatory planning would look at the long-term impacts of this technology, such as the need for upgrades, scalability of the solution as patient numbers grow, and integration with other systems. This type of planning is crucial for the success and longevity of the program but, similar to resource stewardship, is more about strategic alignment and less about the immediate financial evaluation that a cost benefit analysis provides.
In conclusion, while resource stewardship, marketing, and anticipatory planning are all important aspects to consider when implementing a new program, the decision to proceed with a GPS tracking system for patients with dementia primarily rests on a detailed cost benefit analysis. This analysis provides a clear financial perspective on whether the anticipated benefits justify the investment, making it the most direct and relevant approach to answering the question.
質問 # 419
What is one of the most common reasons that patients seek individual psychotherapy?
- A. Their insurance company required therapy before seeing a psychiatric specialist
- B. Unfulfilled expectations and life transitions
- C. Episodes of dissociative thinking
- D. Prior to a career change
正解：B
解説：
Because medications alone do not treat a person's environmental or interpersonal stressors and their responses to stressors, an integrated approach is the most beneficial in treating mental illness.
The most common reasons patients seek individual psychotherapy are as follows:
* Loss
* Interpersonal conflict
* Symptomatic presentations such as panic, anxiety, phobias, and negativity
* Unfulfilled expectations and life transitions
* Character issues such as narcissism or aggressiveness
