A parent reports seizure-like activity in a 4-month-old infant with no fever. What is most important for the nurse to inquire about?

Inquiring about the ratio of formula to water used when mixing a bottle is particularly important in this scenario. Infants who are not receiving an adequate ratio of nutrients may experience electrolyte imbalances or metabolic derangements, which can lead to seizure-like activities. Conditions such as hyponatremia or hypocalcemia can manifest as seizure-like symptoms and can be critical to identify and manage promptly.

Although other factors like the duration of the seizure-like activity, the infant’s sleep patterns, and the family history of seizures can provide valuable information for a comprehensive assessment, the immediate concern regarding nutritional adequacy and potential metabolic issues makes the inquiry about the formula and water ratio paramount. This can help determine if the infant's seizures may be related to inadequate feeding practices rather than purely neurological issues or underlying genetic conditions.
