NR 546 MIDTERM 1: NEUROTRANSMITTERS: TEST QUESTIONS
WITH ACCURATE SOLUTIONS
Which neurotransmitter(s) may be responsible for a client's symptoms of depression?
Select all that apply. -- Answer ✔✔ increased levels of acetylcholine
increased levels of serotonin
increased levels of glutamate
decreased levels of norepinephrine
decreased levels of histamine
Imbalanced levels of acetylcholine, norepinephrine, serotonin, histamine, or glutamate
can contribute to symptoms of depression. -- Answer ✔✔ true
This enzyme system is responsible for metabolizing many psychotropic medications --
Answer ✔✔ cytochrome P450
Drug metabolism is influenced by client factors such as ___________, ___________,
____________, or other ________________. In older adults' drug metabolization is
decreased, so dosages may need to be reduced to prevent toxicity. Other drugs and
substances such as nicotine or caffeine can be either inducers, which increase the rate of
drug metabolism, or inhibitors, which decrease the rate of drug metabolism.
Polypharmacy is another factor which is common in the care of clients with psychiatric
disorders. Not only do clients with psychiatric disorders often need more than one
medication to control symptoms, particularly in those with the diagnosis of
schizophrenia or bipolar illness, but they often need subsequent medications to manage
side effects. -- Answer ✔✔ age, smoking, caffeine intake, or other medications.
A client who is a poor metabolizer has a lower concentration of the necessary enzyme
to metabolize a drug, which results in higher blood concentrations of the drug. Higher
concentrations of drugs increase the risk of side effects and adverse reactions. --
Answer ✔✔
, inhibits the reuptake of serotonin, which can cause nausea, agitation, headache, and
sexual dysfunction -- Answer ✔✔ Selective Serotonin Reuptake Inhibitors
inhibits the reuptake of serotonin and norepinephrine, which can cause nausea,
sweating, insomnia, tremors, sexual dysfunction -- Answer ✔✔ Serotonin and
Norepinephrine Reuptake Inhibitors
inhibits reuptake of serotonin and norepinephrine, which can cause sexual dysfunction
blocks norepinephrine receptors, which can cause hypotension and tachycardia
blocks histamine receptors, which can cause sedation and weight gain
blocks acetylcholine receptors, which can cause dry mouth, constipation, blurred vision,
and urinary retention -- Answer ✔✔ Tricyclic Antidepressants
increases norepinephrine and serotonin by inhibiting the enzyme that inactivates it,
which can cause sedation, dizziness, sexual dysfunction, and hypertensive crisis --
Answer ✔✔ Monoamine Oxidase Inhibitors
increases the receptor affinity for GABA, which can cause dependence and confusion --
Answer ✔✔ Benzodiazepines
inhibits the reuptake of norepinephrine and dopamine, which can cause insomnia, dry
mouth, tremors, and seizuresX -- Answer ✔✔ Bupropion
The most common action of psychotropic drugs is to modify the actions of G-protein-
linked receptors, which occurs on a spectrum. The agonist spectrum ranges from
antagonist, which blocks the action of a neurotransmitter, to agonists, which fully
stimulate G-protein-linked receptors. In the middle of the spectrum are partial agonists,
which stimulate receptors to a lesser degree than an agonist or natural
neurotransmitter (Stahl, 2021). Watch this video Links to an external site.to learn more
about the agonist spectrum. -- Answer ✔✔
SSRIs, SNRIs, and tricyclic antidepressants _______________ serotonin levels.
Benzodiazepines do not impact serotonin levels. -- Answer ✔✔ increase
Joshua presents to the PMHNP with symptoms of schizophrenia. Nicotine stains are
noted on his mouth and hands. He confirms that he smokes at least 2 to 3 packs of
