Final answer:
The nurse should document the client's refusal to take medication and inform the healthcare provider. Forceful administration or withholding the medication without clear medical rationale is not advised.
Step-by-step explanation:
If a nurse is caring for a client who has a history of substance use disorder and the client refuses to take prescribed oral lorazepam and becomes physically aggressive, the nurse should: C) Document the refusal and inform the healthcare provider. It is crucial to maintain a safe environment for both the client and staff. Administering the medication by force could escalate the situation and may be against the rights of the client. Withholding the medication for a certain time without a clear medical rationale might negatively impact the client's treatment plan. The healthcare provider can then assess the situation and determine the best course of action regarding the client's treatment and management of their aggression.
