A nurse is caring for several clients with major thought disorders such as schizophrenia. They are all being treated with neuroleptic drugs. How do these drugs act in the body to promote mental health? By inhibiting enzymes at the postsynaptic receptor site By decreasing serotonin at the postsynaptic receptor site By increasing dopamine uptake at the postsynaptic receptor site By blocking access to dopamine receptors at the postsynaptic receptor site
By blocking access to dopamine receptors at the postsynaptic receptor site Rationale Neuroleptics block access to dopamine receptors, rather than inhibiting enzymes, at postsynaptic sites. They increase, not decrease, serotonin at postsynaptic sites.
Which drug most commonly causes extrapyramidal side effects (EPS)? Clozapine Haloperidol Risperidone Aripiprazole
Haloperidol Rationale Haloperidol is a typical antipsychotic that commonly causes extrapyramidal side effects. Clozapine is an atypical antipsychotic that has a low risk of causing extrapyramidal side effects. Risperidone and aripiprazole have a low risk of causing extrapyramidal side effects.
Imipramine, 75 mg three times per day, is prescribed for a client. What nursing action is appropriate when this medication is being administered? Telling the client that barbiturates and steroids will not be prescribed Warning the client not to eat cheese, fermented products, and chicken liver Monitoring the client for increased tolerance and reporting when the dosage is no longer effective Having the client checked for increased intraocular pressure and teaching about glaucoma symptoms
Having the client checked for increased intraocular pressure and teaching about glaucoma symptoms Rationale Glaucoma is one of the side effects of imipramine, and the client should be taught about the symptoms. Tolerance is not an issue with tricyclic antidepressants such as imipramine. The other actions are true of monoamine oxidase inhibitors (MAOIs); imipramine is not an MAOI.
A client with the diagnosis of schizophrenia, paranoid type, has been receiving a phenothiazine drug. When the psychiatric daycare center plans a fishing trip, it will be important for the nurse to take which action? Provide the client with sunscreen. Caution the client to limit exertion during the trip. Give the client an extra dose of medication to take after lunch. Take the client's blood pressure before allowing participation in the outing.
Provide the client with sunscreen. Rationale Phenothiazines commonly cause a photosensitivity that can be controlled with sunscreen. Limiting activity is not a necessary precaution when phenothiazines are prescribed. The medication must be administered as prescribed. Participating in the outing should not negatively affect the client's blood pressure.
