NR546 WEEK 2 TEST | PHARMACOKINETICS &
NEUROTRANSMITTERS | 2026/2027 NURSING STUDY GUIDE
1. The nurse working in the community health clinic is assessing risk factors that
can decrease medication effectiveness for clients diagnosed with
schizophrenia. Which client behavior is likely to decrease the effectiveness of
psychotropic medications?
Hears voices more often than usual.
Smokes at least 20 cigarettes daily.
Misses a medication appointment at the clinic.
Takes a morning medication later in the day.
2. Discuss the implications of trazodone's histamine-blocking effect on its use in
treating depression.
Trazodone's histamine-blocking effect can lead to sedation, making
it less suitable as a first-line treatment for depression.
Trazodone's histamine-blocking effect enhances its antidepressant
properties.
Trazodone's histamine-blocking effect has no impact on its
antidepressant efficacy.
Trazodone's histamine-blocking effect is beneficial for anxiety
disorders.
3. What is true about Norepinephrine?
It reduces emotions
It is implicated in the 'fight or flight' response
, Is associated with pleasure seeking behavior
Low levels are associated with aggression
It is not associated with depression
4. What is pharmacokinetics?
The study of how a person's genetic make-up affects their response to
medicines.
The science of the preparation of drugs.
The study of how the body absorbs, distributes, metabolizes, and
eliminates drugs.
The science dealing with actions of drugs on the body.
5. Describe how psychotropic medications influence neurotransmitter levels
and their significance in treating psychiatric disorders.
Psychotropic medications influence neurotransmitter levels, which
are crucial for regulating mood and behavior in psychiatric
disorders.
Psychotropic medications only affect physical health and have no role
in mental health.
Psychotropic medications work by directly altering brain structure.
Psychotropic medications are primarily used for pain management.
6. A 70-year-old patient is prescribed a new antidepressant. Considering client-
specific factors, what should the healthcare provider monitor closely?
The patient's cultural background and beliefs about medication.
The patient's dietary preferences and exercise routine.
Potential drug interactions and altered metabolism due to age.
, The patient's family history of psychiatric disorders.
7. When treating mental illness with psychotropic medications what is the focus
of the treatment?
correcting brain anatomical defects
regulating social behaviors
altering brain neurochemistry
activating the body's normal response to stress
8. If a patient is experiencing severe depression and their serotonin levels are
found to be low, what treatment approach might be considered to address
their symptoms?
Prescribing a selective serotonin reuptake inhibitor (SSRI)
Increasing physical exercise without medication
Suggesting complete withdrawal from social interactions
Recommending a high-sugar diet
9. If a neurotransmitter functions to inhibit neurons, then it is ________ the likelihood
that the neuron it is communicating with will fire.
supporting
maintaining
increasing
decreasing
10. What is the interaction between olanzapine and smoking?
, Olanzapine counteracts the harmful effects of smoking on lung
health, making it a preferred treatment for smokers with mental health
condition
Smoking has no impact on olanzapine's effectiveness, and it can be
used without concern.
Smoking reduces the effectiveness of olanzapine, requiring higher
doses for therapeutic effects.
Smoking increases the metabolism of olanzapine, potentially
leading to lower blood levels of the medication
11. Describe how client-specific factors can influence drug metabolism in
pharmacokinetics.
Client-specific factors are only relevant for over-the-counter
medications.
Client-specific factors such as age, genetics, and health status can
alter how drugs are metabolized in the body.
Client-specific factors only affect drug efficacy, not metabolism.
Client-specific factors have no impact on drug metabolism.
12. A patient is taking multiple medications that interact with each other. How
might this affect their drug metabolism?
It would have no effect on drug metabolism.
It could lead to altered drug metabolism, potentially increasing
toxicity or reducing efficacy.
It would only affect the metabolism of the first medication taken.
It would enhance the effectiveness of all medications.
