A woman in preterm labor at 30 weeks of gestation receives two 12 mg doses of betamethasone (Celestane) intramuscularly. The purpose of this pharmacologic treatment is to:

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.

Infants of diabetic mothers (IDM) are at risk of hypoglycemia because they have been exposed to high levels of glucose in utero. The fetus responds to this high glucose level by producing high levels of insulin to regulate the glucose level. After delivery, the glucose supply from the mother is cut off and the infant's insulin levels remain high, leading to hypoglycemia.

Additionally, the infant's ability to produce glucose is immature and may not be sufficient to maintain normal blood glucose levels, especially if the infant is premature or small for gestational age. Therefore, IDM requires close monitoring of their blood glucose levels to prevent and treat hypoglycemia.
