Step-by-step explanation:
The side effect of haldol (Haloperidol) that needs to be reported immediately to the healthcare provider is B) Dystonic reaction. Dystonic reaction is a severe adverse reaction that can occur with the use of antipsychotic medications like haldol. It is characterized by abnormal muscle contractions, often affecting the neck, face, and tongue, leading to difficulty speaking or swallowing.
Other side effects of haldol include muscle flaccidity (A), mood swings (C), and dry, harsh cough (D). While these side effects should also be monitored, they do not require immediate medical attention as dystonic reaction does. It is important to report any concerning symptoms to the healthcare provider for proper evaluation and management.
