The nurse should observe most closely for drug toxicity when a client receives a
medication that has which characteristic?
• Low bioavailability
• Rapid onset of action
• Short half life
• Narrow therapeutic index.
• Rationale: A drug with a narrow therapeutic index has a high risk for toxicity
because there is a narrow range between the therapeutic dose and the toxic
dose.

Answer is not narcan
- A client experiencing withdrawal from the benzodiazepines alprazolam (Xanax) is
demonstrating severe agitation and tremors. What is the best initial nursing action?
• Administer naloxone (Narcan) per PNR protocol
• Initiate seizure precautions
• Obtain a serum drug screen
• Instruct the family about withdrawal symptoms.
• Rationale: Withdrawal of CNS depressants, such as Xanax, results in rebound
over-excitation of the CNS. Since the client exhibiting tremors, the nurse should
anticipate seizure activity and protect the client. [Show Less]
