Which of the following is an example of a chemical restraint?

A drug that is used for discipline is an example of a chemical restraint because it is administered with the intention to control behavior rather than to provide a therapeutic benefit. Chemical restraints are medications that are utilized to limit a person's movement or to manage their behavior in a way that is not related to a medical condition being treated. This can include controlling agitation or aggression in a patient when less restrictive measures have failed, and it typically must be used judiciously, as it raises ethical concerns regarding consent and patient rights.

In contrast, medications for pain relief, treatments for respiratory distress, and nutritional supplements are associated with the management of specific health issues or conditions, aimed at improving the patient's overall well-being rather than restraining their behavior. Each of these options serves a primary therapeutic purpose, contrasting sharply with the intent behind using a drug for disciplinary reasons.
