Priority teaching for a patient taking clozapine should include which instruction?
- A. Report sore throat and fever immediately.
- B. Avoid foods high in polyunsaturated fat.
- C. Use water-based lotions for rashes.
- D. Avoid unprotected sex.
Correct Answer: A
Rationale: Clozapine therapy may produce agranulocytosis a rare but serious decrease in granulated white blood cells (WBCs); therefore, signs of infection should be immediately reported to the health care provider. In addition, the patient should have white blood cell levels measured weekly. The other options are not relevant to clozapine administration.
The nurse wants to assess for disturbances in circadian rhythms in a patient admitted for major depressive disorder. Which question best implements this assessment?
- A. Do you ever see or hear things that others do not?
- B. Do you have problems with short-term memory?
- C. How would you describe your sleep pattern?
- D. How would you describe your thinking?
Correct Answer: C
Rationale: Mood changes throughout the day are related to circadian rhythms. Questions about sleep pattern would also be relevant to circadian rhythms. The question about seeing or hearing things is relevant to the assessment for illusions and hallucinations. The question about thinking is relevant to the assessment of thought processes. The other question is relevant to assessment of memory.
A patient taking an antipsychotic medication develops restlessness and an uncontrollable need to be in motion. A nurse can correctly analyze that these symptoms are related to which drug action?
- A. Anticholinergic effects
- B. Dopamine-blocking effects
- C. Endocrine-stimulating effects
- D. Ability to stimulate spinal nerves
Correct Answer: B
Rationale: Medications that block dopamine often produce disturbances of movement (extrapyramidal side effects) such as akathisia because dopamine affects neurons involved in both the thought processes and movement regulation. Anticholinergic effects include dry mouth, blurred vision, urinary retention, and constipation. Akathisia is not caused by endocrine stimulation or spinal nerve stimulation.
The spouse of a patient diagnosed with schizophrenia asks, 'Which neurotransmitters are more active when a person has schizophrenia?' The nurse's response will focus on which neurotransmitters? (Select all that apply.)
- A. GABA
- B. Substance P
- C. Histamine
- D. Dopamine
- E. Norepinephrine
Correct Answer: D,E
Rationale: Dopamine plays a role in the integration of thoughts and emotions, and excess dopamine is implicated in the thought disturbances of schizophrenia. Increased activity of norepinephrine also occurs. Substance P is most related to the pain experience. Histamine decrease is associated with depression. Increased GABA is associated with anxiety reduction.
The laboratory report for a patient taking clozapine indicates the patient is experiencing agranulocytosis. The nurse should implement which intervention first?
- A. Report the laboratory results to the health care provider.
- B. Give the next dose of the medication as prescribed.
- C. Administer aspirin and force fluids.
- D. Repeat the laboratory tests.
Correct Answer: A
Rationale: These laboratory values indicate the possibility of agranulocytosis, a serious side effect of clozapine therapy. These results must be immediately reported to the health care provider. The drug should be withheld because the health care provider will discontinue it. The health care provider may repeat the laboratory test, but, in the meantime, the drug should be withheld. Giving aspirin and forcing fluids are measures that are less important than stopping the administration of the drug.
