A client is admitted to the emergency department with signs of opioid overdose, such as pinpoint pupils, respiratory depression, and altered mental status. The nurse anticipates that the prescriber will order which of the following medications to reverse the effects of the opioid?

Correct answer: a) Agranulocytosis

Rationale: Clozapine is an atypical antipsychotic that acts on the central nervous system to reduce psychotic symptoms such as hallucinations, delusions, and paranoia. It also has a low potential for abuse and dependence, which is why it is classified as a Schedule V medication. However, it can cause agranulocytosis, a life-threatening condition characterized by a severe decrease in white blood cells that increases the risk of infection. The nurse should monitor the client's complete blood count (CBC) regularly and report any signs of infection such as fever, sore throat, or mouth ulcers.

Incorrect choices:

b) Stevens-Johnson syndrome: This is a rare but serious skin reaction that can be caused by some medications such as sulfonamides, anticonvulsants, and allopurinol, not clozapine.

c) Torsades de pointes: This is a rare but serious cardiac arrhythmia that can be caused by some medications such as antiarrhythmics, antibiotics, and antidepressants that prolong the QT interval, not clozapine.

d) Rhabdomyolysis: This is a rare but serious condition characterized by muscle breakdown and renal failure that can be caused by some medications such as statins, antipsychotics, and corticosteroids, not clozapine.

Correct answer: d) All of the above.

Rationale: The nurse should follow all of these actions to ensure the safe and legal administration of controlled substances. These actions help prevent medication errors, diversion, and misuse of controlled substances.

Incorrect choices:
a) Verify the client's identity using two identifiers before administering the medication.: This is correct but not comprehensive as it does not include other actions that are required for controlled substances.
b) Document the administration of the medication on a separate controlled substance record.: This is correct but not comprehensive as it does not include other actions that are required for controlled substances.
c) Count the remaining tablets of oxycodone with another nurse at the end of each shift.: This is correct but not comprehensive as it does not include other actions that are required for controlled substances.
