What is a common consequence of drawing blood from a hematoma?

Drawing blood from a hematoma can lead to multiple complications, which is why selecting 'all of the above' encapsulates the potential issues effectively.

When blood is drawn from a hematoma, the integrity of the surrounding tissue is compromised, leading to discomfort for the patient. This discomfort arises not just from the procedure itself, but from the presence of the hematoma, which generally signifies previous bleeding or injury to the area.

Moreover, drawing blood from a hematoma can also impact the accuracy of test results. Hematomas contain pooled blood and may alter the composition of the sample, leading to inaccuracies in laboratory results. This can particularly affect tests that are sensitive to the levels of certain substances in the blood, thereby skewing results and possibly leading to incorrect diagnoses or treatment plans.

Lastly, any procedure that invades the integrity of the skin and tissue carries an inherent risk of introducing pathogens that could lead to infection. Hematomas might already have disrupted the normal protective barriers of the skin and can act as a potential site for microbial entry, raising the likelihood of infection after the blood draw.

Considering all these factors, it's apparent that drawing blood from a hematoma can indeed decrease patient comfort, reduce the accuracy of test results, and increase the risk
