A nurse is preparing the environment for a newly admitted client with a documented history of self-injurious behaviors (SIBs) in a secure inpatient mental health unit. Which of the following environmental modifications is most essential in reducing the client’s risk of harm?

Choice A reason: Padded clothing and shoes may reduce injury during agitation but do not address the broader risk of self-harm using sharp or breakable objects. This is not the most essential intervention. Choice B reason: Removing bedside tables eliminates one potential surface for injury but does not comprehensively address the risk posed by sharp or breakable items. It is too limited in scope. Choice C reason: Allowing controlled access to electronic devices may provide distraction but does not directly reduce risk of harm. Safety must be prioritized before therapeutic engagement. Choice D reason: Removing sharp and breakable items is the most essential environmental modification. These objects pose the greatest risk for self-injury, and their removal directly reduces the client’s ability to harm themselves. This is the most comprehensive and immediate safety measure.
