When preparing to assist with applying a cast to a preschooler's arm, the nurse should consider actions that help reduce anxiety and ensure safety. Among the options provided, the most appropriate action is:<br /><br />**Wrap the arm of the child's doll or toy prior to the procedure.**<br /><br />This action can help the child understand what will happen in a non-threatening way and can reduce fear by making the process more relatable and less intimidating. It also provides an opportunity for the child to ask questions and express any concerns they might have.<br /><br />The other options are not recommended:<br />- Telling the child, "This will make your arm feel better," may not be entirely accurate as the initial application of a cast can sometimes cause discomfort.<br />- Placing a heated fan at the bedside to facilitate drying is not advisable because it can lead to uneven drying and potential burns if the cast becomes too hot.<br />- Supporting the casted arm with a firm grasp is unnecessary and could potentially cause discomfort or damage to the cast. Instead, gentle support should be provided as needed.
