A 2-year-old is brought to the ED after ingesting an unknown amount of liquid drain cleaner. The child is drooling and has erythematous sloughing on the lips. What is the priority nursing intervention and what action is strictly contraindicated?
Show answer →Priority: Airway assessment and maintaining NPO status. Contraindication: Do NOT induce emesis or attempt to neutralize the substance with acid/alkali. Emesis re-exposes the esophagus to the corrosive agent, increasing the risk of perforation and aspiration. Clinical Pearl: PNCB often tests the no emesis rule for corrosives and hydrocarbons. Gastric lavage and activated charcoal are also generally avoided as they interfere with endoscopy, which is the definitive diagnostic tool for assessing esophageal damage within 24 hours.
A 14-month-old is suspected of swallowing a button battery 30 minutes ago. The X-ray shows the battery is lodged in the mid-esophagus. What is the immediate management, and what pre-hospital intervention is recommended for children >1 year old?
Show answer →Immediate Management: Emergent endoscopic removal. Esophageal lodging can cause liquefactive necrosis and perforation within 2 hours. Pre-hospital: If ingestion was within 12 hours and the child is >1 year old, administer 10 mL of honey every 10 minutes (up to 6 doses). Honey coats the battery and neutralizes the localized alkaline environment, slowing tissue damage. Clinical Reasoning: PNCB focuses on the urgency of esophageal batteries versus the watchful waiting of gastric batteries.
An 18-month-old presents with a 4-hour history of vomiting and bloody diarrhea. The parent found an open bottle of prenatal vitamins. Which specific antidote should the nurse anticipate, and what is a classic side effect of this treatment?
Show answer →Antidote: Deferoxamine (Chelation therapy). Side effect: Vin rose (reddish-pink) colored urine, which indicates the iron is being successfully chelated and excreted. Clinical Pearl: Iron toxicity occurs in stages. Stage 1 (0.5-6 hrs) is GI-focused. Stage 2 (6-24 hrs) is a latent period where the child appears to improve before Stage 3 (metabolic acidosis/shock) occurs. PNCB tests the recognition of the latent period to prevent premature discharge.
A child is brought to the ED after ingesting a large amount of acetaminophen 2 hours ago. The nurse notes the child is currently asymptomatic. What is the gold-standard tool used to determine treatment, and when should it be drawn?
Show answer →The Rumack-Matthew Nomogram is used to determine the risk of hepatotoxicity and the need for N-acetylcysteine (NAC). The blood level must be drawn at exactly 4 hours post-ingestion (or as soon as possible after 4 hours) to be accurately plotted. Drawing earlier than 4 hours results in an unreliable level due to ongoing absorption. NAC is most effective when given within 8 hours of ingestion. Note: Acetaminophen is the most common pediatric poisoning.
A 2-year-old presents with sudden onset of bradycardia, hypotension, and a significantly elevated blood glucose level. The parents suspect the child took several of a relative's heart pills. Which class of medication is likely responsible?
Show answer →Calcium Channel Blockers (CCBs). Hyperglycemia is a classic differentiator for CCB toxicity in pediatric patients because CCBs inhibit insulin release from the pancreas. Management: High-dose insulin euglycemic therapy (HIET), IV calcium, and glucagon. Clinical Pearl: Even one pill can kill a toddler when dealing with CCBs or Beta-Blockers. Vigilant monitoring for cardiovascular collapse is essential.
