During this phase of a disaster, evaluation of the disaster plan and cleanup of the area are hallmark activities.

Effective health communication requires that messages be designed with the audience's needs and characteristics in mind, and pretesting is an important part of this process. Pretesting materials for feedback about comprehension helps to ensure that the messages are clear, understandable, and culturally appropriate for the target audience. This also allows the nurse to make any necessary revisions to improve the materials' effectiveness.

The nurse's target audience should be specific to those who have infants or who are expecting an infant, rather than including all residents, as this is too broad and may not effectively reach the intended audience. Additionally, the use of radio advertisements developed in English only may not be effective for reaching all members of the community, particularly those who do not speak English as their primary language. Lastly, materials written at a high school reading level may not be appropriate for all members of the community, particularly those with lower levels of literacy.

In the case of a prolapsed umbilical cord, the first priority intervention is to relieve pressure on the cord. Placing the woman in the knee-chest position or Trendelenburg position with the hips elevated is the best way to achieve this. This position helps to reduce the compression of the cord and improve fetal oxygenation.
Option B is incorrect because while oxygen may be necessary, relieving pressure on the cord is the priority.
Option C is incorrect because a vaginal birth should not proceed with a prolapsed umbilical cord, as it can cause cord compression and fetal distress.
Option D is incorrect because covering the cord in sterile gauze soaked in saline is not a priority intervention and may not be effective in relieving pressure on the cord.
