Difficulty: Very hardMental Health Concepts

A nurse on an acute mental health unit responds to a sudden commotion in the common area. A client experiencing substance-induced psychosis is hurling chairs at the reinforced windows and shouting, "The gas is coming through the vents!" Verbal de-escalation attempts have completely failed, and the client is now attempting to lift a heavy wooden table. Which actions should the nurse implement? Select all that apply.

  1. Evacuate all other clients and visitors from the common area immediately.Answer
  2. Activate the facility's designated psychiatric emergency response team.Answer
  3. C
    Ask the client, "Why do you believe poisonous gas is entering the ventilation system?"
  4. Prepare to administer a prescribed short-acting intramuscular antipsychotic medication.Answer
  5. E
    Approach the client independently with open hands to demonstrate a non-threatening posture.
  6. F
    Instruct the staff to apply four-point mechanical restraints as the initial measure to gain control.

Answer

The nurse should evacuate bystanders from the area, activate the psychiatric emergency response team, and prepare a short-acting intramuscular antipsychotic medication.
In a psychiatric emergency involving imminent violence and the failure of verbal de-escalation, the nurse must prioritize physical safety and follow the hierarchy of least restrictive interventions. Evacuating bystanders immediately removes them from physical danger. Activating the emergency response team provides necessary backup, as managing an armed, violent client requires a coordinated team approach. Preparing a short-acting intramuscular antipsychotic is the correct next clinical step; chemical interventions are less restrictive than mechanical restraints and are explicitly indicated for acute agitation with psychosis when the client poses a danger to themselves or others.

Step-by-Step Solution

1
Assess the immediate environment for physical safety threats.
The nurse identifies that the client is actively violent, armed with heavy furniture, and unresponsive to verbal de-escalation.
Safety of the client, peers, and staff is the absolute highest priority in any psychiatric emergency.
2
Remove vulnerable individuals from the immediate vicinity.
Other clients and visitors are evacuated from the common area.
This minimizes the risk of collateral injury and removes potential stimuli that could be exacerbating the client's paranoia.
3
Summon additional trained personnel.
The psychiatric emergency response team is activated.
A coordinated team is required to safely manage a violent client, providing a 'show of force' that can sometimes prompt voluntary de-escalation.
4
Select the next least restrictive intervention to manage the behavior.
The nurse prepares a short-acting intramuscular antipsychotic medication.
Because verbal de-escalation has failed and violence is occurring, chemical restraint (medication) is the next appropriate step before resorting to seclusion or mechanical restraints.
