NURS 6630 psychopharmacology Midterm Exam - Walden University. QUESTION 1 1. A noncompliant patient states, “Why do you want me to put this poison in my body?” Identify the best response made b... y the psychiatric-mental health nurse practitioner (PMHNP). A. “You have to take your medication to become stable.” B. “ Medications work by increasing the types of neurotransmitters produced by the human brain.” C. “Most medications that work in the brain will result in restoring an imbalance of one or more neurotransmitters that your body already produces helping to alleviate your symptoms .” D. “Why do you believe that your medication is poison?” 1 points QUESTION 2 1. Ms. Hill is currently being treated for schizophrenia but has stopped taking her medications due to some side effects she claims she was experiencing. She presents to the clinic today with worsening symptoms. She is experiencing anhedonia, agitation, attentional impairment, and affective blunting. Which one of the symptoms mentioned is considered a positive symptom of schizophrenia? A. Anhedonia B. Agitation C. Attentional Impairment D. Affective Blunting 1 points QUESTION 3 1. Which statement about neurotransmitters and medications is true? A. Endorphins were discovered before morphine which lead to the use of the opioids for pain control. B. Several psychiatric medications have been developed after discoveries of endogenous neurotransmitters and defining their function in the brain. C. Medications work by sending messages to neurotransmitters enabling them to work more effectively. D. An imbalance of serotonin has been directly linked to depression. Following the discovery of this neurotransmitter, pharmacologists were able to develop a well-known drug- Prozac as the first medication used to restore the balance of serotonin. 1 points QUESTION 4 1. When an unstable patient asks why it is necessary to add medications to his current regimen, the PMHNP’s best response would be: A. "More often than you would think, multiple medications should always be tried together to see what happens.” B. “Due to this being your first hospitalization after starting medication treatment for the first time in your life, the only way to effectively manage your symptoms is by adding additional medications in hopes that it will work for you." C. “Many psychiatric illnesses involve several dys-functioning neurotransmitter systems in the brain. Often, a single medication may only effect one or two of the dys-functioning systems. The addition of another medication can work with the current medication in stabilizing multiple neurotransmitter systems and help to alleviate your symptoms.” D. “I understand your concerns. Often times, it is necessary to switch medications after short periods of time to better manage your symptoms. We will discontinue your current regimen and start another single drug agent.” 1 points QUESTION 5 1. During gene expression, what must occur prior to a gene being expressed? A. Transcription factor must bind to the regulatory region within the cell’s nucleus. B. RNA must be converted to mRNA. C. The coding region must separate from the regulatory region. D. RNA polymerase must inhibit the process of changing RNA to mRNA. 1 points QUESTION 6 1. While genes have potential to modify behavior, behavior can also modify genes. How do genes impact this process? A. Genes impact neuron functioning directly. B. Changes made to proteins lead to changes in behavior. C. Neurons are able to impact protein synthesis. D. Genes impact the DNA of a cell, leading to changes in behavior. 1 points QUESTION 7 1. Though medications have the ability to target neurotransmitter release into the synapse by the presynaptic neuron it is not always necessary. The PMHNP understands that this is because: A. Neurotransmission occurring along the axon is normally at a level to prevent symptoms of mental illness and rarely require augmentation from medication therapy. B. Neurotransmission is minimally affected by medication therapy when compared to the baseline neurotransmitter release of a resting neuron. C. Neurotransmitters can spread by diffusion. D. The post synaptic neuron can produce and release its’ own neurotransmitter allowing it to function properly. 1 points QUESTION 8 1. Why is the cytochrome P450 enzyme system of significance to the PMHNP? A. The kidneys play a role with excretion of the medication, and if a patient has kidney damage, the dose must be increased to be effective. B. The bioavailability of the medication after it passes through the stomach and liver can be altered. C. The medication’s chemical composition changes when it comes in contact with the acid in the stomach. D. The CYP enzyme system is a steady and predictable process that prescribers must understand to treat conditions effectively. 1 points QUESTION 9 1.

About 1 out of 5 Asians requires lower-than-normal doses of some antidepressants and antipsychotics. B. The term polymorphic refers to the body’s ability to break a medication down several ways, and this patient may require higher doses of certain antidepressants and antipsychotics. C.

As it relates to G-protein linked receptors, what does the PMHNP understand about medications that are used in practice? A. Most medications that act on G-protein linked receptors have antagonistic traits. B. The majority of medications used in practice are full agonists and are used to stimulate the body’s natural neurotransmitters. C. Most medications act as partial agonists because they allow the body to use only what is needed. D. Medications used in practice may act as inverse agonists if the dosage is too high. 1 points QUESTION 11 1.

The PMHNP is aware that which factor may impact the dose needed to effectively treat his condition: A. The patient smokes cigarettes. B. The patient has hypertension. C.
