An outpatient clinic that has been receiving haloperidol (Haldol) for 2 days develops muscular rigidity, altered consciousness, a temperature of 103, and trouble breathing on day 3. The LPN/LVN interprets these findings as indicating which of the following?

Correct Answer: A

Rationale: Neuroleptic Malignant Syndrome (NMS) is a life-threatening condition characterized by hyperthermia, muscle rigidity, altered consciousness, and autonomic dysregulation. It is a rare but serious side effect of antipsychotic medications like haloperidol (Haldol). NMS requires immediate intervention, including discontinuation of the offending medication and supportive care. Tardive dyskinesia (Choice B) is a different condition characterized by involuntary movements of the face and extremities that can occur with long-term antipsychotic use. Extrapyramidal adverse effects (Choice C) encompass a range of movement disorders like dystonia, akathisia, and parkinsonism that can result from antipsychotic medications, but they do not present with hyperthermia and altered consciousness as in NMS. Drug-induced parkinsonism (Choice D) is a form of parkinsonism caused by certain medications, but it typically presents with symptoms similar to Parkinson's disease, such as tremor, bradykinesia, and rigidity, without the severe hyperthermia and autonomic dysregulation seen in NMS.

Correct Answer: B

Rationale: The best response for the LPN/LVN to provide to the wife of a male client diagnosed with schizophrenia is choice B: 'It is a chemical imbalance in the brain that causes disorganized thinking.' This response educates the wife about the nature of schizophrenia, explaining that it is caused by a chemical imbalance in the brain leading to disorganized thinking, helping her understand the condition better. Choice A does not directly address the question and instead shifts the focus to a different aspect. Choice C gives false reassurance without providing necessary information about schizophrenia. Choice D deflects the responsibility of providing information to the psychologist instead of addressing the wife's concerns directly.

Correct Answer: D

Rationale: Nausea and vomiting should be reported immediately because they could indicate lithium toxicity, which requires urgent medical attention to prevent more severe effects. Short-term memory loss, depressed affect, and weight gain are common side effects of lithium but do not require immediate medical attention compared to symptoms of toxicity like nausea and vomiting.

Correct Answer: C

Rationale: The correct answer is C. Describing oneself as a social drinker who consumes alcoholic beverages daily raises concerns about potential alcohol abuse issues. The CAGE questionnaire is a tool used to screen for alcohol use disorder. Choice A is incorrect as memory difficulties post-traumatic brain injury do not directly indicate a need for the CAGE questionnaire. Choice B is incorrect as the use of antidepressants, while important to note, does not specifically warrant the use of the CAGE questionnaire. Choice D is incorrect as a recent sexual assault, while significant, does not directly relate to the need for alcohol abuse screening using the CAGE questionnaire.

Correct Answer: A

Rationale: Neurotransmitters are chemicals in the brain that act as messengers between neurons, influencing various psychological functions. Choice A correctly defines neurotransmitters by stating that they are chemical messengers that cause brain cells to turn on or off. This is the function of neurotransmitters in transmitting signals between neurons. Choices B, C, and D are incorrect because they do not accurately describe neurotransmitters and their role in the brain.
