What condition may occur following the administration of Haldol, as indicated by muscle stiffness?

1. Extrapyramidal symptoms

2. Dystonia

3. Akathisia

4. Tardive dyskinesia

The correct answer is: Dystonia

The correct answer, which identifies the condition that may occur following the administration of Haldol and is indicated by muscle stiffness, is dystonia. Dystonia is a type of extrapyramidal symptom characterized by sustained muscle contractions, abnormal postures, or twisting movements, which can indeed manifest as muscle stiffness. When administering Haldol (haloperidol), a typical antipsychotic, the risk of various extrapyramidal side effects exists. Dystonia can occur acutely, particularly shortly after starting the medication or increasing the dose, and is often seen in younger patients or those who are new to antipsychotic treatment. It involves involuntary muscle spasms and can significantly affect mobility and comfort. While extrapyramidal symptoms is a broader category that includes dystonia, akathisia, and tardive dyskinesia, the specific focus on muscle stiffness directly aligns with the definition and presentation of dystonia. Akathisia, on the other hand, generally involves a feeling of inner restlessness and an uncontrollable need to be in constant motion, and tardive dyskinesia manifests as involuntary repetitive movements and often develops after long-term use of antipsychotic medications. Understanding this nuance in symptoms is crucial for
