What must a CPI rule out if a parent claims their child bruises easily?

When a parent claims that their child bruises easily, it is essential to consider underlying medical conditions that could cause this symptom. A blood disorder, such as hemophilia or thrombocytopenia, is a significant concern because these disorders affect the blood's ability to clot properly. This means that even minor bumps or injuries can result in excessive bruising, which may be perceived as the child bruising easily.

When assessing the child's condition, ruling out a blood disorder is crucial because it directly relates to the mechanism of bruising. Medical history, physical examination, and possibly blood tests would be necessary to determine the presence of such disorders.

Other factors like malnutrition, genetic conditions, or childhood trauma could also play a role in bruising but are less directly related to the primary concern in this context. While malnutrition can potentially lead to increased bruising due to vitamin deficiencies, and genetic conditions can produce symptoms affecting bruise healing or appearance, the immediate focus should be on ruling out blood disorders first due to their urgency and potential severity.
