A nurse in the emergency department (ED) is caring for a 2-year-old toddler. Complete the diagram by dragging from the choices below to specify what condition the toddler is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the toddler's progress.

Rationale for correct choices • Intussusception: The toddler presents with sudden, episodic abdominal pain, drawing knees to chest, high-pitched crying, and intermittent periods of comfort. The “red currant jelly” stool is classic for intussusception, indicating intestinal bleeding and mucous. Vomiting and decreased urine output further support dehydration from obstructive bowel pathology. • Maintain NPO status: Keeping the toddler NPO prevents further gastrointestinal compromise and prepares them for diagnostic procedures such as an air or contrast enema or potential surgery. Oral intake could worsen obstruction or lead to vomiting and aspiration. • Prepare for surgery: Surgical intervention may be required if non-surgical reduction (e.g., air or contrast enema) is unsuccessful or if complications like perforation or peritonitis develop. Early preparation ensures timely intervention to prevent bowel necrosis. • Abdominal distension: Monitoring for abdominal distension helps detect worsening obstruction or bowel compromise. Progressive distension may indicate that the intussusception has not reduced or that ischemia is developing. • Signs of dehydration: Vomiting, decreased urine output, and irritability increase the toddler’s risk for dehydration. Monitoring for signs such as dry mucous membranes, lethargy, or tachycardia allows timely fluid replacement and prevents further complications. Rationale for incorrect choices • Prepare the toddler for an upper gastrointestinal series: An upper GI series is typically used to evaluate malrotation or other upper GI anomalies, not first-line for intussusception. A contrast or air enema is the preferred diagnostic and therapeutic procedure. • Administer oral rehydration solution: Oral fluids are contraindicated because the toddler is at risk of vomiting due to bowel obstruction. Administering oral rehydration could worsen aspiration risk and delay surgical intervention. • Educate the guardian about a gas enema: While a gas enema is a treatment option, education alone is not the immediate nursing priority. The toddler requires stabilization, NPO status, and preparation for possible surgical intervention. • Celiac disease: Celiac disease presents with chronic malabsorption, growth delays, and diarrhea, not acute, intermittent abdominal pain with "red jelly" stools. The toddler’s sudden onset and episodic nature of symptoms do not fit this condition. • Gastroesophageal reflux disease (GERD): GERD usually causes chronic regurgitation, irritability after feeds, and discomfort, but it does not cause "red jelly" stools or sudden episodes of severe abdominal pain. The acute presentation suggests a structural obstruction rather than reflux. • Appendicitis: Appendicitis often presents with continuous abdominal pain, initially periumbilical migrating to the right lower quadrant, with fever and gradual onset. The episodic pain, bloody stools, and age of the toddler make appendicitis less likely. • Urine specific gravity: While it can indicate hydration, direct monitoring for clinical signs of dehydration is more immediate and actionable in an acute setting. • Epigastric pain 30 to 60 min after eating: This monitoring parameter is more relevant for GERD or peptic ulcer disease. The toddler’s pain is intermittent, sudden, and unrelated to meal timing, making it inappropriate for this assessment. • Soft, brown stool: Monitoring for normal stool is not immediately useful because the toddler currently has bloody "red jelly" stools, which indicate active pathology. Focus of management should remain on detecting complications and dehydration.
