A nurse is reinforcing education to the caregiver of a 2-year-old toddler diagnosed with lead poisoning. Which of the following statements should the nurse make?

A. "Anencephaly affects male fetuses more than female fetuses." Anencephaly occurs more frequently in female fetuses than in males. Studies suggest a slightly higher prevalence in female infants, though the exact reason is unclear.

B. "Cancer during pregnancy is a risk factor for anencephaly." There is no known link between cancer during pregnancy and anencephaly. The primary risk factors include folic acid deficiency, maternal diabetes, and exposure to teratogens (e.g., certain medications, high temperatures, or environmental toxins).

C. "These defects occur in the embryonic stage of pregnancy." Anencephaly is a neural tube defect (NTD) that occurs during the embryonic stage, specifically between weeks 3 and 4 of gestation. During this period, the neural tube fails to close properly, leading to incomplete development of the brain and skull.

D. "Most newborns who have anencephaly survive 1 month." Anencephaly is almost always fatal, with most affected newborns dying within hours to days after birth. There is no cure, and long-term survival is extremely rare due to the severe brain malformation.

A. A 3-year-old toddler who aspirated several sunflower seeds and continues to cough with an O₂ saturation of 91%. This child is the highest priority due to the risk of airway obstruction. Persistent coughing and decreased oxygen saturation suggest partial obstruction, which could worsen. Immediate assessment and intervention are necessary to prevent respiratory distress or complete airway blockage.

B. A 6-year-old child admitted with asthma exacerbation who used a rescue inhaler 16 hours ago. While asthma exacerbations can be serious, this child is currently stable since there is no indication of respiratory distress or worsening symptoms requiring immediate intervention.

C. A 15-year-old adolescent who had a laparoscopic appendectomy 30 hours ago, rates their pain a 3 on a scale of 1 to 10, and is preparing for discharge this morning. This client is stable, with mild pain and no reported complications. They do not require immediate attention.

D. An 18-month-old admitted for dehydration 2 days ago who has had six wet diapers in the last 24 hours and ate 90% of their meals. This child's hydration status appears to be improving, with adequate urine output and good oral intake, making them a lower priority compared to a child with respiratory compromise.
