A 25-year-old woman with Type II Diabetes Mellitus should be educated on all the following regarding preconception care, except:

A history of cesarean section for fetal distress is an indication for a repeat cesarean section in subsequent pregnancies, as the risk of recurrence of fetal distress is higher. A trial of labor after cesarean (TOLAC) may be attempted in some cases, but a planned cesarean section is often recommended.
Option B is incorrect because fear of natural childbirth is not a medical indication for a cesarean section.
Option C is incorrect because gestational diabetes does not typically require a cesarean section unless other complications arise, such as fetal macrosomia or failed induction of labor.
Option D is incorrect because a history of cephalopelvic disproportion with the first pregnancy may not necessarily require a cesarean section in subsequent pregnancies. A trial of labor may be attempted, depending on the circumstances.

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.
