A nurse is reviewing home care with a client who has multiple sclerosis. Which of the following precautions should the nurse recommend to promote client safety?

Choice A reason: Instructing pregnant visitors to stay 3 feet away is insufficient, as radiation from a sealed implant requires greater distance (typically 6 feet) or complete avoidance. Pregnant individuals should not visit to minimize fetal exposure, making this precaution inadequate and incorrect for safety.
Choice B reason: Wearing a lead apron shields the nurse from radiation exposure during close contact with the sealed implant, adhering to ALARA (As Low As Reasonably Achievable) principles. This protects the nurse while providing care, making it a necessary and correct safety measure.
Choice C reason: Placing the client in a semi-private room is unsafe, as radiation from the implant could expose other patients. A private room is required to minimize radiation risk to others, making this action incorrect and against radiation safety protocols.
Choice D reason: Closing the client’s door reduces radiation exposure to others outside the room, as sealed implants emit continuous radiation. This containment measure, combined with signage, ensures safety for staff and visitors, making it a correct and essential action.
Choice E reason: Limiting visitors to 30 minutes per day minimizes cumulative radiation exposure, protecting visitors from the sealed implant’s emissions. Time restrictions are standard in radiation safety protocols, ensuring minimal risk while allowing controlled visits, making this a correct action.

Choice A reason: Experiencing delusions can contribute to agitation, but it is not the strongest predictor of violence. Delusions may lead to unpredictable behavior, but past actions are more reliable indicators, so this factor is less definitive, making it incorrect.
Choice B reason: A history of being in prison indicates past legal issues but not necessarily violent behavior. Incarceration alone is not a direct predictor of future violence, so this factor is less reliable than actual violent history, making it incorrect.
Choice C reason: A history of violent behavior is the best predictor of future violence, as past actions strongly correlate with recurrence, per evidence-based risk assessments. This reliable indicator guides safety planning, making it the correct factor to emphasize in teaching.
Choice D reason: Substance use disorder increases impulsivity and aggression risk, but it is less predictive than a documented history of violence. Substance use is a contributing factor, not the strongest indicator, so this is incorrect compared to past behavior.
