Choice A rationale:

Using a face pain scale to indicate pain intensity is a suitable method for assessing pain in children who are pre-verbal or developmentally disabled.

This approach involves showing the child a series of faces with different expressions ranging from happy to very sad, and the child can point to the face that best represents their current level of pain.

This visual scale provides a simple and effective way to gauge pain intensity when verbal communication is limited or not possible.

Choice B rationale:

Watching how the child behaves in response to pain is another valuable method for assessing pain in children who cannot communicate verbally or have developmental disabilities.

Observing their behavior, such as crying, grimacing, or changes in posture, can provide important clues about their pain level.

Non-verbal cues are especially relevant in assessing the pain experience of pre-verbal or developmentally disabled children.

Choice C rationale:

Using a doll to demonstrate the location of pain may not be an effective method for assessing pain in children with limited communication skills or developmental disabilities.

This method assumes that the child can understand and accurately point to the doll to indicate the location of their pain, which may not always be the case.

Choice D rationale:

Asking questions about the child's pain is generally not suitable for pre-verbal or developmentally disabled children, as they may not be able to provide coherent responses to questions about their pain.

Choice E rationale:

Conducting a comprehensive pain assessment is essential, but it often includes methods like choices A and B for pre-verbal or developmentally disabled children.

While a comprehensive assessment is crucial, the methods for these specific populations should prioritize non-verbal cues and visual pain scales.
