Psychotropic Medication Quiz Quizlet Questions
Question 1 of 5
To test for gross motor skill and coordination of a 6-year-old child, which of these techniques would be appropriate? Ask the child to:
Correct Answer: A
Rationale: The correct answer is A: Hop on one foot. This task assesses balance, coordination, and gross motor skills in a 6-year-old child. Hopping on one foot requires a combination of strength, balance, and coordination, making it an appropriate test for gross motor skills. Standing on the head (B) is not developmentally appropriate and poses a risk of injury. Touching finger to nose (C) tests fine motor skills, not gross motor skills. Making 'funny' faces (D) does not assess motor skills or coordination.
Question 2 of 5
A man who was found wandering in a park at 2 AM has been brought to the emergency department for an examination; he said he fell and hit his head. During the examination, the nurse asks him to use his index finger to touch the nurse's finger, then his own nose, then the nurse's finger again (which has been moved to a different location). The patient is clumsy, unable to follow the instructions, and overshoots the mark, missing the finger. The nurse should suspect which of the following?
Correct Answer: C
Rationale: The correct answer is C: Acute alcohol intoxication. The patient's inability to follow the finger-to-nose test and clumsiness are classic signs of cerebellar dysfunction, which is commonly seen in individuals under the influence of alcohol. Alcohol affects the cerebellum, leading to impaired coordination and balance. This is confirmed by the patient overshooting the mark and missing the target. The other choices (A, B, D) are less likely as they do not explain the patient's specific presentation and symptoms, which are indicative of acute alcohol intoxication.
Question 3 of 5
The parent of an adolescent with schizophrenia asks a nurse, 'My child’s doctor ordered a positron-emission tomography (PET) scan. What is that?' Select the nurse’s best reply.
Correct Answer: D
Rationale: The correct answer is D: PET is a special scan that shows blood flow and activity in the brain. Rationale: 1. PET scans use a radioactive substance injected into the bloodstream to highlight areas of high metabolic activity in the brain. 2. This helps in assessing brain function by showing how well different areas of the brain are working. 3. It is commonly used in diagnosing conditions like schizophrenia to observe brain activity patterns that may indicate the presence of the disorder. Summary: A: Incorrect - PET does not use a magnetic field or gamma waves and does not rely on metal implants. B: Incorrect - PET is not an x-ray image and does not specifically show structures or past brain injuries. C: Incorrect - PET does not pass an electrical current or measure brain wave activity; it focuses on blood flow and metabolic activity.
Question 4 of 5
The therapeutic action of monoamine oxidase inhibitors (MAOIs) blocks neurotransmitter reuptake, causing:
Correct Answer: A
Rationale: The correct answer is A: increased concentration of neurotransmitters in the synaptic gap. MAOIs inhibit the enzyme monoamine oxidase, which breaks down neurotransmitters like serotonin, norepinephrine, and dopamine. By blocking this enzyme, MAOIs increase the levels of these neurotransmitters in the synaptic gap, enhancing their effects. This results in improved mood and decreased symptoms of depression or anxiety. Choice B is incorrect because MAOIs do not directly affect the concentration of neurotransmitters in the serum. Choice C is incorrect as MAOIs do not cause destruction of receptor sites. Choice D is incorrect because MAOIs do not directly stimulate the limbic system; rather, they modulate neurotransmitter levels to improve symptoms.
Question 5 of 5
A nurse can anticipate anticholinergic side effects will be likely when a patient is taking:
Correct Answer: D
Rationale: The correct answer is D: fluphenazine (Prolixin). Fluphenazine is a typical antipsychotic medication that exerts its effects by blocking dopamine receptors in the brain. This action leads to an increase in dopamine levels, which can cause anticholinergic side effects such as dry mouth, constipation, blurred vision, and urinary retention. The other choices, lithium (A), buspirone (B), and risperidone (C), do not typically exhibit significant anticholinergic side effects. Lithium is used to treat bipolar disorder, buspirone is an anxiolytic medication, and risperidone is an atypical antipsychotic that has a lower risk of causing anticholinergic effects compared to typical antipsychotics like fluphenazine.
