A nurse is teaching a client who has a new prescription for fluoxetine to treat depression. Which of the following statements by the client indicates an understanding of the teaching?

A. Dystonia - Dystonia presents as sustained or intermittent muscle contractions causing abnormal, often repetitive, movements or postures. It is an acute extrapyramidal side effect of antipsychotic medications like chlorpromazine but typically manifests as sudden-onset muscle spasms rather than involuntary movements of the tongue and face.

B. Tardive dyskinesia - Tardive dyskinesia is a late-appearing movement disorder characterized by involuntary, repetitive movements of the face, tongue, and limbs. It is associated with long-term use of antipsychotic medications like chlorpromazine and typically develops after months to years of treatment.

C. Parkinsonism - Parkinsonism resembles Parkinson's disease and is characterized by symptoms such as tremor, rigidity, bradykinesia, and postural instability. While antipsychotic medications can cause Parkinsonism as an adverse effect, it usually presents with symptoms different from those described in the scenario.

D. Akathisia - Akathisia is characterized by an inner feeling of restlessness and the urge to move, often accompanied by pacing and inability to sit still. It is an acute extrapyramidal side effect of antipsychotic medications but does not manifest as involuntary movements of the tongue and face as described in the scenario.

A. "You will need to take this medication on an empty stomach."

Lithium is typically taken with food to minimize gastrointestinal side effects. Instructing the client to take it on an empty stomach would be incorrect.

B. "You will need to stop this medication if you experience diarrhea."

Diarrhea is not typically a reason to stop lithium therapy. However, persistent diarrhea can lead to dehydration and electrolyte imbalances, which may affect lithium levels. It's essential for the client to report persistent diarrhea to their healthcare provider for further evaluation and management.

C. "You will need to consume a low-salt diet while on this medication."

A low-salt diet is not typically recommended with lithium therapy. In fact, lithium can cause sodium depletion, so it's important for clients to maintain adequate salt intake unless otherwise instructed by their healthcare provider.

D. "You will need your blood levels drawn weekly during the first month."

This statement is correct. Monitoring serum lithium levels is crucial to ensure the medication's effectiveness and prevent toxicity. Initially, frequent monitoring is necessary to establish the appropriate dosage and assess for any signs of toxicity. Weekly blood level checks during the first month of therapy are common practice.
