Chelation is indicated only for children with elevated blood lead levels (typically >45 mcg/dL). Starting it without testing is inappropriate.

Advising the parents that lead poisoning is a myth is incorrect and dangerous. Lead poisoning is a well-documented cause of serious pediatric morbidity.

Recommending a high-protein diet to prevent lead absorption is incorrect. Nutrition such as iron, calcium, and vitamin C can help reduce absorption, but it does not replace the need for screening.

Beginning chest compressions is appropriate if the child has no pulse, but in drowning, the immediate problem is lack of oxygen. Rescue breaths come first.

Administering IV fluids is not the initial intervention in an unresponsive drowning victim. Airway and breathing take priority.

Checking for a pulse is important, but rescue breaths should not be delayed; hypoxemia must be corrected first.

Most drownings are a result of suicide: In children, drowning is usually accidental (e.g., bathtubs, pools, buckets). Suicide-related drowning is rare in pediatrics.

Drowning can only occur in deep water: Children can drown in very shallow water, as little as a few centimeters, such as bathtubs, toilets, or buckets.

Children are less susceptible to drowning than adults: Children are more susceptible due to smaller body size, curiosity, limited motor skills, and lack of safety awareness.

While behavioral changes like irritability or decreased attention span may occur with lead poisoning, hyperactivity is nonspecific and not considered a classic hallmark.

Chronic lead poisoning can cause hypertension, but this is more common in adults due to long-term vascular and renal effects, not typically in young children.

Decreased lead level is not a manifestation but rather an expected outcome after treatment such as chelation therapy.

Inducing vomiting is no longer recommended because it can cause aspiration or esophageal injury, especially with caustic substances or hydrocarbons.

Administering activated charcoal is effective for many ingestions if given within 1 hour, but should only be used after professional guidance, since it is contraindicated in some poisonings such as heavy metals and corrosives.

Preparing for gastric lavage is rarely used today, and only in very specific, life-threatening ingestions, due to risk of aspiration and complications.
