Which patient would have the most immediate and powerful effect from this drug? a. A healthy adolescent b. A 76-year -old patient with malnutrition c. A woman in the second trimester of pregnancy d. An adult with a fractured femur from a sporting accident ANS: B The older malnourished patient would have fewer serum proteins to bind the drug; therefore, higher amounts of free drug would be avail able to act immediately. The patients described in the distracters would have normal protein levels, so the drug would be bound.

A novice nurse asks, "What is the role of psychopharmacology in the psychotherapeutic management model?" A mentor should respond that psychopharmacology makes it possible to: a. use the least restrictive treatment alternatives. b. prevent violence against nurses. c. identify desirable outcomes. d. determine psychopathology. ANS: A By effectively treating psychotic symptoms, the incidence of violent behaviors has been reduced. This makes possible the use of the least restrictive treatment alternative, an important facet of psychot herapeutic management. Psychopharmacology does not make the other options possible.

The parent of a teen diagnosed with schizophrenia asks, "Why does schizophrenia usually appear in adolescence?" The nurse's reply would be based on which premise? a. Stimulation of neurotransmitters is unstable. b. Neuronal system complexity stabilizes. c. Dendrite branching becomes complete in adolescence. d. Amino acid production increases. ANS: C Arborization, or branching of dendrites, is a process that continues into adolescence. Some authorities have suggested that this might account for the appearance of schizophrenia at this period in life. The other options are of no relevance.

The primary mechanisms of action of certain antidepressants result from neurotransmitter inactivation by enzyme -based metabolism and: https://www.stuvia.com/ https://www.stuvia.com/ a. electrochemical stimulation. b. stimulation of natural precursors. c. extraction of precursors from the bloodstream. d. reuptake into the presynaptic storage vesicles. ANS: D Neurotransmitters are inactivated in two ways: (1) they are metabolized by enzymes, and (2) they are taken back into the presynaptic storage vesicles—a process called reuptake. The other options have no physiologic basis in fact. DIF: Cognitive level: Understanding REF: p. 125 TOP: Nursing process: Implementation MSC: NCLEX: Physiologic Integrity 5. When discussing treatmen t of an aggressive patient with psychosis, a health care provider says, "I plan to prescribe the original antipsychotic drug." Which medication is relevant to the statement? a. Paroxetine (Paxil) b. Clozapine (Clozaril) c. Imipramine (Tofranil) d. Chlorpromazine (Thorazine) ANS: D Only chlorpromazine and clozapine are antipsychotics. Chlorpromazine is a traditional drug, introduced in the early 1950s, whereas clozapine is a newer drug, introduced in the 1990s. Paroxetine and imipramine are antidepressants.

A nurse assesses a newly hospitalized patient with a long history of serious and persistent mental illness. The priority assessment information to obtain regarding medication safety is: a. adverse reactions to drugs taken previously. b. history of drug compliance and noncompliance. c. level of support available from significant others. d. length of time on various psychotropic medications. ANS: A Information related to safety is the nurse's priority. Adverse reactions to psychotropic medications can be dangerous, even life-threatening. If a patient has had an adverse reaction to a particular drug, it would be unwise to administer it again. The other options do not address a safety issue.

Studies about psychiatric patients' understanding of psychopharmacology suggest that the nursing diagnosis most applicable is: a. deficient knowledge related to drug therapy. b. impaired memory related to drug side effects. c. impaired decision making related to drug dependency. d. disturbed thought processes related to anticipation of side effects. ANS: A Research has shown that most patients do not know important facts about the medications prescribed for them. As a result, they are often noncompliant. As
