A charge nurse is teaching new staff members about factors that increase a client’s risk to become violent.

Which of the following risk factors should the nurse include as the best predictor of future violence?

This is because varicella, or chickenpox, is a highly contagious disease caused by the varicella- zoster virus (VZV), which can spread through the air or by direct contact with the fluid from the blisters. A negative air pressure room prevents the air from the room from circulating to other areas of the hospital, reducing the risk of transmission to other patients and staff.

Choice A is wrong because aspirin should not be given to children with chickenpox, as it can cause a serious condition called Reye’s syndrome, which affects the brain and liver. Instead, acetaminophen can be used to reduce fever.

Choice B is wrong because droplet precautions are not enough to prevent the spread of chickenpox. Droplet precautions involve wearing a mask and gloves when in close contact with the patient, but they do not prevent the virus from traveling through the air. Airborne precautions, which include a negative air pressure room and wearing a respirator, are needed for chickenpox.

Choice D is wrong because Koplik spots are not a sign of chickenpox, but of measles, another viral infection that causes a rash. Chickenpox causes an itchy rash with small, fluid-filled blisters that crust over.

Previous violent behavior. According to the web search results, this is the best predictor of future violence among the given risk factors.
Other risk factors include past history of aggression, poor impulse control, and violence. Comorbidity that leads to acts of violence (psychotic delusions, command hallucinations, violent angry reactions with cognitive disorders).
Choice A is wrong because a history of being in prison is not a direct cause of violence, but rather a possible consequence of it.
Choice C is wrong because male gender is not a sufficient factor to predict violence, as there are many other variables involved.
Choice D is wrong because experiencing delusions is not necessarily associated with violence unless they are of a paranoid or persecutory nature.
Normal ranges for violence risk assessment are not standardized, but some tools that can be used include the Historical Clinical Risk Management-20 (HCR-20), the Violence Risk Appraisal Guide (VRAG), and the Psychopathy Checklist-Revised (PCL-R). These tools use different scales and criteria to evaluate the likelihood of violent behavior in individuals.
