A nurse in an emergency department is assessing a school-age child who was brought in by their parents and has scald burns to both hands and wrists. The nurse suspects physical abuse.

Which of the following actions should the nurse take?

Choice A rationale:

Sodium level of 142 mEq/L is within the normal range (135-145 mEq/L) for adults. However, normal ranges for children might vary slightly, but 142 mEq/L is not indicative of dehydration on its own.

Choice B rationale:

Respiratory rate of 22/min is within the normal range for a 3-year-old child (20-30 breaths/min) This rate alone does not provide evidence of dehydration.

Choice C rationale:

Potassium level of 3.9 mEq/L is within the normal range (3.5-5.1 mEq/L) for children. Like sodium, normal ranges for potassium may differ slightly in pediatric patients, but 3.9 mEq/L is not alarming on its own.

Choice D rationale:

Heart rate of 148/min is elevated for a 3-year-old child. Tachycardia is a common sign of dehydration in pediatric patients. This increased heart rate indicates the body's compensatory mechanism to maintain cardiac output in response to decreased blood volume, a typical consequence of dehydration.

Initiate transmission-based precautions.

Rationale:

1. B- Encouraging oral fluids is an important intervention for a child who has a fever, as it helps prevent dehydration and electrolyte imbalance. However, it is not the priority intervention, as it does not address the risk of infection transmission to other clients or staff.
2. A - Applying topical calamine lotion may help soothe the itching and discomfort caused by the vesicles, but it is not the priority intervention, as it does not prevent infection transmission or treat the underlying cause of the fever.
3. C - Administering acetaminophen as an antipyretic may help reduce the fever and provide symptomatic relief for the child, but it is not the priority intervention, as it does not prevent infection transmission or treat the underlying cause of the fever.
4. D - Initiating transmission-based precautions is the priority intervention, as it protects other clients and staff from exposure to the infectious agent that causes the vesicles and fever. The nurse should wear gloves, gown, mask, and eye protection when caring for the child, and place them in a private room or cohort them with other clients who have similar symptoms.
