After a seizure, a 9-month-old infant has stable vital signs. What assessment indicates appropriate treatment measures were taken?

In the context of assessing a 9-month-old infant after a seizure, the improvement in responsiveness is a strong indicator that appropriate treatment measures have been taken. A seizure can result in altered mental status and responsiveness, and one of the primary goals of postictal care is to ensure the infant returns to baseline level of alertness and interaction. If the infant shows improved responsiveness, it suggests that the brain is recovering effectively, minimizing the risk of potential complications associated with seizures.

While other vital signs, like heart rate, blood pressure, and temperature, can provide helpful information regarding the infant's overall condition, they do not necessarily reflect the adequacy of treatment measures in the same way that responsiveness does. A stable heart rate or blood pressure may be seen in a variety of conditions, not specifically linked to recovery from a seizure. A mild temperature of 99.9°F is relatively normal and could occur for many reasons unrelated to the seizure itself, rendering it less specific for evaluating recovery post-seizure. In summary, an improvement in responsiveness is the most direct and relevant indicator that the infant is recovering well from the seizure, reflecting effective management and care.
