A client with psychosis is receiving olanzapine. What special information about this drug does the nurse recall? It must be administered by Z-track administration. A special tyramine-free diet is required. It dissolves instantly after oral administration. An empty stomach increases its effectiveness. ----CORRECT ANSWER------ It dissolves instantly after oral administration. Rationale: Olanzapine is an orally disintegrating tablet, meaning that it will instantly dissolve on contact with moisture. It can be given intramuscularly, but Z-track administration is not necessary. Tyramine-free diets are necessary with monoamine oxidase inhibitors, not antipsychotics. An empty stomach is not necessary with this medication. A healthcare provider prescribes phenobarbital sodium for a client who had a tonicclonic seizure. The nurse assesses the client's knowledge after teaching about the adverse effects of this drug. What responses should the client identify as a reason for calling the healthcare provider? Loss of appetite or persistent fatigue Anal itching or dizziness when standing up Diarrhea or a rash on the upper part of the body Decreased tolerance to common foods or constipation ----CORRECT ANSWER------ Loss of appetite or persistent fatigue Rationale: Phenobarbital depresses the central nervous system, particularly the motor cortex, producing adverse effects such as lethargy, loss of appetite, depression, and vertigo. Anal itching, diarrhea, rashes, and decreased tolerance to common foods or constipation are not side effects of phenobarbital.
