A client with a personality disorder asks the nurse, 'Is it true I have an inherited brain disorder?' The nurse replies, knowing that:
- A. There is proof that personality disorders are inherited
- B. All persons with personality disorders display brain abnormalities
- C. Individuals with personality disorders show an error in brain glucose metabolism
- D. Individuals with personality disorders manifest some biological markers
Correct Answer: D
Rationale: Rationale:
D is correct because individuals with personality disorders can manifest biological markers indicating a potential biological basis for the disorder. This does not imply that all individuals with personality disorders display brain abnormalities (B), have errors in brain glucose metabolism (C), or that there is definitive proof of inheritance (A). Biological markers suggest a potential biological component but do not guarantee inheritance or specific brain abnormalities.

When making a distinction as to whether an elderly patient has confusion related to delirium or another problem, what information would be of particular value?
- A. Evidence of spasticity or flaccidity
- B. The patient's level of motor activity
- C. Medications the patient has recently taken
- D. Level of preoccupation with somatic symptoms
Correct Answer: C
Rationale: The correct answer is C: Medications the patient has recently taken. This information is crucial because certain medications can cause delirium in elderly patients. By reviewing the patient's recent medications, healthcare providers can identify potential drug-induced delirium and adjust treatment accordingly. Spasticity or flaccidity (choice A) is more indicative of neurologic conditions, not delirium. The patient's level of motor activity (choice B) may provide some insight but is not as specific to delirium as medication history. The level of preoccupation with somatic symptoms (choice D) is more relevant to other psychiatric conditions and does not directly help in distinguishing delirium.
What would be an expected outcome for a patient with anorexia nervosa undergoing treatment?
- A. The patient will stabilize weight at a normal level.
- B. The patient will participate in group therapy regularly.
- C. The patient will express satisfaction with their body image.
- D. The patient will regain full cognitive function and independence.
Correct Answer: A
Rationale: The correct answer is A. In Anorexia Nervosa treatment, the primary goal is weight restoration to a healthy level. This is crucial for physical health and recovery. Stabilizing weight at a normal level is a key indicator of treatment success. Choices B, C, and D are incorrect as they do not address the core issue of weight restoration, which is essential in treating Anorexia Nervosa. Group therapy, body image satisfaction, and cognitive function are important aspects of treatment but not the primary outcome measure for patients with anorexia nervosa.
The nurse is administering haloperidol (Haldol) to a client experiencing delusions and hallucinations associated with schizophrenia. The nurse can expect symptom abatement as a result of the drug's action to:
- A. Reduce the number of brain cells that crave dopamine
- B. Block dopamine receptors, making dopamine less available
- C. Enhance dopamine receptors, making more dopamine available
- D. Cause increased cellular production of dopamine
Correct Answer: B
Rationale: The correct answer is B because haloperidol is a typical antipsychotic that works by blocking dopamine receptors in the brain. By blocking these receptors, haloperidol reduces the effects of excess dopamine, which is known to contribute to symptoms of schizophrenia such as delusions and hallucinations. This action helps alleviate the positive symptoms of schizophrenia.
Choice A is incorrect because haloperidol does not reduce the number of brain cells that crave dopamine; it acts on the receptors themselves. Choice C is incorrect because enhancing dopamine receptors would lead to an increase in the effects of dopamine, worsening symptoms. Choice D is incorrect because haloperidol does not cause increased cellular production of dopamine; it blocks dopamine receptors instead.
Which of the following is an example of a Specific Learning Disability?
- A. Mental Retardation
- B. Dyslexia
- C. ADHD
- D. Autistic spectrum disorders
Correct Answer: B
Rationale: Dyslexia: A persistent, chronic condition in which reading ability lags behind that of non-impaired individuals for the course of most of their lifetime.
The client has been taking lithium and fluoxetine (Prozac) for almost a week. During today's assessment, the nurse notes a temperature of 39°C, muscle rigidity, and confusion. The client's signs and symptoms suggest:
- A. Dystonic reactions
- B. Bradykinesic side effects
- C. Extrapyramidal side effects
- D. Neuroleptic malignant syndrome
Correct Answer: D
Rationale: The correct answer is D: Neuroleptic malignant syndrome (NMS). This is indicated by the client's elevated temperature, muscle rigidity, and confusion, which are classic symptoms of NMS. NMS is a serious, potentially life-threatening condition associated with the use of antipsychotic medications like lithium and fluoxetine. The onset of NMS is often rapid and can lead to severe complications if not treated promptly. Dystonic reactions (choice A) involve sudden and involuntary muscle contractions, which are not consistent with the client's symptoms. Bradykinesic side effects (choice B) refer to slowed movements, which are not present in this case. Extrapyramidal side effects (choice C) typically include symptoms like tremors, stiffness, and restlessness, but do not encompass the combination of symptoms seen in NMS.
