Report new lip smacking, tongue movements, or facial grimacing immediately, as TD may become permanent.

Test yourself first: 5 questions
Question 1 of 5
A client has been taking an antipsychotic and is now scheduled to be assessed with the Abnormal Involuntary Movement Scale (AIMS). What is the primary purpose of this assessment tool?
Answer: A. The Abnormal Involuntary Movement Scale (AIMS) is used to screen for and monitor abnormal involuntary movements, primarily to detect early signs of tardive dyskinesia in clients on antipsychotic therapy. Routine AIMS assessments allow early intervention, since tardive dyskinesia may become irreversible.
Question 2 of 5
A client has been taking an antipsychotic for several years and now shows involuntary lip smacking, tongue protrusion, and facial grimacing. Which adverse effect does the nurse recognize?
Answer: B. Repetitive, involuntary movements of the face, tongue, and mouth (lip smacking, tongue protrusion, grimacing) developing after long-term antipsychotic use describe tardive dyskinesia. It may be irreversible, so early recognition and dose review are important.
Question 3 of 5
A client started on an antipsychotic paces constantly and reports an inner feeling of restlessness and inability to sit still. The nurse identifies this as which extrapyramidal effect?
Answer: B. Akathisia is a subjective sense of inner restlessness with an inability to remain still, often shown by pacing or rocking. It is frequently mistaken for worsening agitation but is a medication side effect. Treatment may include lowering the dose or adding a beta blocker such as propranolol. Dystonia involves muscle spasms, tardive dyskinesia involves involuntary facial movements, and pseudoparkinsonism involves tremor and bradykinesia.
Question 4 of 5
A client on long-term antipsychotic therapy exhibits involuntary lip smacking, tongue protrusion, and facial grimacing. The nurse identifies this as which extrapyramidal effect?
Answer: B. Tardive dyskinesia is a late-onset extrapyramidal side effect of long-term antipsychotic use, characterized by involuntary, repetitive movements of the face, tongue, and mouth (lip smacking, tongue protrusion, grimacing). It may be irreversible and must be reported promptly.
Question 5 of 5
A client taking an antipsychotic develops involuntary lip-smacking, tongue protrusion, and facial grimacing after long-term therapy. The nurse recognizes these findings as which condition?
Answer: C. Tardive dyskinesia is a late-onset extrapyramidal effect of long-term antipsychotic use, characterized by involuntary, repetitive movements of the face, tongue, and mouth, such as lip-smacking and tongue protrusion. It may be irreversible, so early recognition and reporting are essential. Acute dystonia involves sustained muscle spasms early in therapy, akathisia is motor restlessness, and pseudoparkinsonism causes tremor and rigidity.
Keep the streak going with more questions like these, each with a full rationale.
What is tardive dyskinesia?
It often appears after months to years of treatment and may be irreversible, so early detection is critical. Classic signs are lip smacking, tongue protrusion, chewing motions, and grimacing.
Key points to remember
- TD develops after prolonged (months to years) antipsychotic therapy, unlike acute dystonia or akathisia which occur early.
- Characteristic involuntary movements: lip smacking, tongue thrusting/protrusion, chewing, grimacing, blinking, and choreoathetoid limb movements.
- It is frequently irreversible, so prevention and early recognition are key; movements may persist even after the drug is stopped.
- The Abnormal Involuntary Movement Scale (AIMS) is used to screen for and monitor TD periodically.
- Management includes lowering the dose or switching to a second-generation antipsychotic, and VMAT2 inhibitors (valbenazine, deutetrabenazine) can treat it.
- Anticholinergics help acute dystonia/parkinsonism but can worsen TD.
Common causes
- Long-term antipsychotic use
- May be PERMANENT/irreversible
Signs & symptoms
- Lip smacking, tongue protrusion
- Facial grimacing, chewing motions
- Choreoathetoid limb movements
Nursing priorities
- Screen for involuntary movements regularly using the AIMS tool.
- Report early signs to the provider so the drug or dose can be adjusted promptly.
- Distinguish TD from acute, treatable EPS (dystonia, akathisia, pseudoparkinsonism).
- Administer VMAT2 inhibitors as ordered and monitor response.
- Support nutrition and safety if tongue/mouth movements affect eating or swallowing.
Patient teaching
- Report any unusual mouth, tongue, face, or limb movements to your provider right away.
- Continued long-term antipsychotic use requires regular movement check-ups; keep your appointments.
- Do not stop the medication on your own, but tell the team if you notice involuntary movements.
Red flags: report now
- Report new lip smacking, tongue movements, or facial grimacing immediately, as TD may become permanent.
- Do not ignore early extrapyramidal symptoms or assume they will resolve on their own.
