A patient is admitted to the emergency room with an accidental overdose of a substance that is caustic. Which therapeutic option should the nurse question?

A. Complete blood count (CBC): A CBC is a standard laboratory test to evaluate overall health and detect a wide range of disorders, including infection or anemia. It is not contraindicated and may be necessary for comprehensive patient care. B. Placement on a cardiac monitor: Cardiac monitoring is appropriate in cases of overdose as many substances can affect the heart. It helps in early detection of any arrhythmias or other cardiac complications. C. Activated charcoal: Activated charcoal is typically used to bind substances in the gastrointestinal tract to prevent absorption. However, in the case of a caustic substance, it is generally contraindicated because it does not bind well to such substances and may obscure endoscopic evaluation. D. Inducing vomiting: Inducing vomiting is contraindicated in cases of caustic substance ingestion because it can cause additional damage to the esophagus and mouth. It is important to avoid this action to prevent further injury.
