A nurse is evaluating an infant who received treatment for increased intracranial pressure. Which of the following findings should the nurse identify as an indication that the treatment was effective?

A. Soft, flat fontanels: A soft, flat fontanel indicates that intracranial pressure has decreased and is within normal limits. Elevated pressure often causes bulging or tense fontanels, so this finding suggests effective treatment. B. Increased sleepiness: Excessive sleepiness or lethargy can indicate worsening or ongoing increased intracranial pressure, so it is not a sign of effective treatment and requires further assessment. C. Enlarged head circumference: An increasing head circumference in an infant can be a sign of accumulating cerebrospinal fluid or brain swelling, indicating persistent or worsening increased intracranial pressure. D. Crying when disturbed: While crying is a normal infant behavior, excessive irritability or inconsolable crying may indicate discomfort or increased intracranial pressure rather than improvement. Normal, calm behavior is preferable after treatment.
