Question 3 of 5
The parent of an adolescent diagnosed with schizophrenia asks the nurse, My child™s doctor ordered a PET. What kind of test is that? Select the nurse™s best reply.
Correct Answer: B
Rationale: The correct answer is B because a PET scan, or positron-emission tomography, is a type of scan that uses a radioactive substance to show blood flow and brain activity. This is important in diagnosing conditions like schizophrenia. Choice A is incorrect because it describes an MRI, not a PET scan. Choice C describes an EEG, not a PET scan. Choice D describes a CT scan, not a PET scan.
Question 4 of 5
The nurse administers a medication that potentiates the action of ã-aminobutyric acid (GABA). Which effect would be expected?
Correct Answer: A
Rationale: The correct answer is A: Reduced anxiety. GABA is an inhibitory neurotransmitter that helps calm and relax the nervous system. By potentiating its action, the medication would increase GABA's calming effects, leading to reduced anxiety. Choice B (Improved memory) is incorrect as GABA's role is not directly related to memory enhancement. Choice C (More organized thinking) is incorrect as GABA primarily affects mood and anxiety, not cognitive processes. Choice D (Fewer sensory perceptual alterations) is incorrect as GABA modulation would not directly impact sensory perceptions.
Question 5 of 5
The therapeutic action of neurotransmitter inhibitors that block reuptake cause
Correct Answer: B
Rationale: The correct answer is B: increased concentration of the blocked neurotransmitter in the synaptic gap. When neurotransmitter inhibitors block reuptake, they prevent the reabsorption of neurotransmitters by the presynaptic neuron, leading to more neurotransmitters remaining in the synaptic gap. This increased concentration enhances neurotransmission and can help alleviate symptoms associated with neurotransmitter deficiencies. A: decreased concentration of the blocked neurotransmitter in the central nervous system - This is incorrect because blocking reuptake leads to an increased concentration of neurotransmitter in the synaptic gap, not a decrease in the central nervous system. C: destruction of receptor sites specific to the blocked neurotransmitter - This is incorrect because blocking reuptake does not affect receptor sites; it primarily impacts the reuptake process. D: limbic system stimulation - This is incorrect because blocking reuptake does not directly stimulate the limbic system; its primary effect is on neurotransmitter levels in the synaptic gap.
