A patient overdosed on risperidone (Risperdal) 20 minutes ago. The nurse should prepare to take which action?
1. Administer a CNS depressant
2. Administer an anticholinergic
3. Administer activated charcoal
4. Symptom management since there is no other treatment
3
Rationale 1: CNS depressants likely will worsen symptoms.
Rationale 2: Anticholinergic agents likely will worsen symptoms.
Rationale 3: Activated charcoal will bind the Risperdal that has not been absorbed and prevent absorption into the bloodstream.
Rationale 4: symptom management might be warranted, but given that the overdose occurred only 20 minutes ago, there is a different effective treatment.
Global Rationale: Activated charcoal will bind the Risperdal that has not been absorbed and prevent absorption into the bloodstream. Symptom management might be warranted, but given that the overdose occurred only 20 minutes ago, charcoal likely will be effective and should be used. Anticholinergic agents and CNS depressants likely will worsen symptoms.
