Choice A rationale:

Stress management techniques - Teaching parents stress management techniques can help them cope with challenging situations without resorting to abusive behaviors. Reducing parental stress can contribute to a healthier parent-child relationship.

Choice B rationale:

Conflict resolution skills - Teaching parents effective ways to manage conflicts without resorting to violence models healthy behavior for children. It also reduces the likelihood of aggressive behavior in the family environment.

Choice C rationale:

Substance use prevention strategies - Substance abuse can impair judgment and increase the risk of abusive behavior. Educating parents about substance use prevention helps create a safer home environment for children.

Choice D rationale:

Providing home visits to at-risk families - While home visits can be important for assessing and supporting families, they are not considered a primary prevention strategy. Home visits are more aligned with secondary prevention efforts, aimed at identifying and addressing existing issues.

Choice E rationale:

Teaching appropriate use of weapons - This choice is not a primary prevention strategy for child abuse. In fact, promoting weapon use education could potentially introduce more risks into the household environment. It's important to focus on non-violent strategies for conflict resolution and child safety.
