A pregnant, homeless woman who has received no prenatal care presents to the clinic in her third trimester because she is having vaginal bleeding, but reports that she is not in pain. Ultrasound reveals a placenta previa. Which action should the nurse implement?

A: Ensure that the room is warm and undress the child completely. While a warm room is important to keep the child comfortable, undressing the child completely can cause distress and discomfort, especially in toddlers who may feel exposed and vulnerable.

B: Have the parent remove the child's outer clothing and remove the diaper or training pants when necessary. This approach is more appropriate as it allows the child to remain relatively comfortable and secure. The parent’s involvement helps reassure the child, and only removing necessary clothing minimizes distress. It also allows for targeted examination without fully undressing the child, which is less intimidating for toddlers.

C: Help the child take off his/her clothes, removing underwear only to conduct examination of the genitalia. Assisting the child in removing clothes can be helpful, but it might be more comforting and less invasive if the parent is involved in this process. Removing underwear only when necessary for a genital examination is appropriate, but it might still be distressing for the child without prior explanation and parental presence.

D: Prior to helping the child remove his/her clothing, use a paper doll to demonstrate removal of clothing. Demonstrating the process using a paper doll can be an effective way to prepare the child for what will happen during the assessment, reducing anxiety. However, this is more of a preparatory step rather than a direct protocol for the physical assessment itself. It can be a helpful adjunct to the primary method but is not sufficient on its own.

A: Primary source of water. This assessment might be relevant if there is a concern about lead exposure or other contaminants in the water, which can contribute to anemia. Therefore, while important in certain contexts, it is not the most immediate assessment for these specific clinical manifestations.

B: Standard household income. Household income can influence access to nutritious food and overall health. Lower income can lead to food insecurity, poor diet quality, and subsequently, anemia and lower BMI due to inadequate nutrient intake. This can be an indirect but important factor to consider. However, it does not directly assess the child’s dietary intake or specific nutritional deficiencies.

C: Family history of eating disorders. Family history of eating disorders might provide insights into potential genetic or environmental predispositions to eating disorders. However, eating disorders are more commonly associated with adolescents and adults rather than school-age children.

D: Average daily intake of meals. This is the most directly relevant assessment. Analyzing the child's average daily intake of meals can provide immediate insights into potential nutritional deficiencies that might explain both the low hemoglobin level (anemia) and low BMI. Poor dietary intake, particularly of iron-rich foods, can lead to iron-deficiency anemia and inadequate caloric intake, affecting BMI. This assessment helps identify specific dietary issues that can be addressed directly to improve the child’s health.
