A battered and agitated client who experienced a street brawl and has haloperidol 100 mg IM stat. The dose is...

• A. The medication dose prescribed is appropriate for this client
• B. The medication dose prescribed is within the recommended range for this client
• C. There is no concern about the dose
• D. The medication dose prescribed is more than the recommended amount for this client

Answer: (D)

The main idea here is safe dosing for haloperidol when quickly calming an acutely agitated patient. For an IM dose to control agitation, the usual starting amount is about 5 mg, and it can be repeated if needed, but the total daily dose is generally kept around 20–30 mg and not given as a single large 100 mg injection. Administering 100 mg IM stat greatly exceeds typical limits and markedly increases the risk of serious adverse effects, including severe extrapyramidal symptoms (acute dystonia, akathisia, parkinsonism), excessive sedation, hypotension, QT prolongation with potential torsades de pointes, and even neuroleptic malignant syndrome. Because this dose far surpasses what’s recommended for a patient in this situation, it is considered more than the acceptable amount for this client. In practice, if agitation persists, clinicians reassess and use lower doses within safe limits, monitor closely, and consider alternative strategies as appropriate.
