A nurse is contributing to a plan of care for a child who is 3 years of age. Which of the following developmental milestones should the nurse incorporate into the plan of care?

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.

A. "Intussusception is a congenital condition where the layers of the intestinal wall do not form properly." Intussusception is not a congenital malformation but an acquired condition where one part of the intestine telescopes into another, causing obstruction and potential ischemia.

B. "Intussusception is a consequence of weakened abdominal muscles, allowing a portion of the intestine to bulge." This description is more characteristic of a hernia rather than intussusception, which involves the invagination of the intestine rather than a protrusion.

C. "Intussusception results from the twisting of the intestines, causing a blockage in the passage of food." Twisting of the intestines describes volvulus, a separate condition that can also cause bowel obstruction but occurs through a different mechanism than intussusception.

D. "Intussusception occurs when one segment of the intestine slides into another, which can cut off blood supply." This is the correct explanation. The telescoping of the intestine can cause bowel obstruction and compromise blood flow, leading to symptoms such as severe abdominal pain, vomiting, and the passage of red, currant jelly-like stools.
