Foundations of Psychiatric Mental Health Nursing A Clinical Approach, 5th Edition by Elizabeth M. Varcarolis – Test Bank Sample Test Varcarolis: Foundations of Psychiatric Mental Health Nursing: A Clinical Approach, 5th Edition Test Bank Chapter 3: Biological Basis for Understanding Psychotropic Drugs MULTIPLE CHOICE 1) A client asks the nurse, “What are neurotransmitters? My doctor says they are at the root of my problem.” The best reply would be A. “You must feel relieved to know that your problem has a physical basis.” B. “It is a rather high-level concept to explain. Perhaps you should ask the doctor to tell you more.” C. “Neurotransmitters are substances we eat daily that influence the brain functions of memory and mood.” D. “Neurotransmitters are chemicals manufactured in the brain that are responsible for passing messages betw brain cells.” 2) The mother of an adolescent client with obsessive-compulsive disorder tells the nurse, “My daughter’s doctor wants her to be in a research study and to have a PET [positron emission tomography] scan. I do not want her to have to go through any tests that are painful. What should I do?” The best reply for the nurse would be A. “The doctor has made the diagnosis, but having a PET scan would confirm it.” B. “You might want to ask who will pay for the PET scan because they are very expensive.” C. “PET scans involve an injection and lying still while a machine visualizes brain activity.” D. “PET scans involve passing an electrical current through the brain and can be uncomfortable.” 3) The physician mentions that a client’s dementia may be associated with either Alzheimer’s disease or multiple infarcts. For the physician to make a differential diagnosis with the least expensive test, the nurse should expect to prepare the client for a A. computed tomography (CT) scan. B. magnetic resonance imaging (MRI) scan. C. PET scan. D. single-photon emission computed tomography (SPECT) scan. 4) A client has delusions and hallucinations. Before beginning treatment with psychotropic drugs, the physician wishes to rule out the presence of a brain tumor. For which test will the nurse need to prepare the client? A. CT or MRI scan B. PET or SPECT scan C. Cerebral arteriogram D. Neuronal depolarization 5) A client who is being admitted for depression should be assessed for disturbances in circadian rhythms. The question that best implements this assessment is A. “What time of day do you feel worst and when do you feel best?” B. “Do you ever see or hear things that others do not?” C. “How would you describe your thinking?” D. “Would you say your memory is failing?” 6) When the wife of a client with schizophrenia asks which neurotransmitter is implicated in the development of schizophrenia, the nurse should state “The current thinking is that the thought disturbances are related to A. excess dopamine.” B. serotonin deficiency.” C. histamine decrease.” D. increased γ-aminobutyric acid [GABA].” 7) Ongoing assessment and outcome planning for a client with schizophrenia are facilitated if the nurse understands that the medication prescribed to reduce the client’s symptoms targets the neurotransmitter A. dopamine. B. serotonin. C. norepinephrine. D. acetylcholine. 8) The nurse should provide ongoing assessment for a client receiving medication that potentiates the action of GABA relative to A. reduced anxiety. B. improved memory. C. more organized thinking. D. fewer sensory perceptual alterations. 9) On the basis of current knowledge of neurotransmitter effects, the nurse could anticipate that the treatment plan for a client with memory difficulties might include orders to administer medication designed to A. inhibit GABA. B. increase dopamine at receptor sites. C. decrease dopamine at receptor sites. D. prevent destruction of acetylcholine. 10) A client demonstrates disorganized and delusional thinking. The tentative diagnosis is schizophrenia. The nurse can anticipate that a PET scan would be most likely to show dysfunction in the part of the brain called the A. temporal lobe. B. cerebellum. C. brainstem. D. frontal lobe. ..................................................continued................................................................
