A client in the emergency department tells the nurse about being chased by a "serial killer." The client is currently paranoid and is aggressively fighting against any treatment
Which medication does the nurse anticipate will be prescribed for this client?
1. Clozapine (Clozaril) in intramuscular (IM) form
2. Risperidone (Risperdal) IM
3. Loxapine (Loxitane) IM
4. Lorazepam (Ativan) IM
Correct Answer: 4
Rationale 1: Clozaril is given only by mouth and if there is no response to safer drugs.
Rationale 2: The intramuscular form of risperidone takes three weeks to produce a therapeutic response.
Rationale 3: Even though Loxitane may be given intramuscularly, it is restricted to treating mental illness refractory to treatment with safer drugs.
Rationale 4: Benzodiazepines such as Ativan may be administered intramuscularly during the initial treatment period; they provide sedation for agitated clients.

Clozaril is given only by mouth and if there is no response to safer drugs. The intramuscular form of risperidone takes three weeks to produce a therapeutic response.
