When a hematoma occurs after arterial access, which action is recommended?

• A. Shape should be marked and monitored
• B. Distal pulses should be monitored
• C. Massage toward incision site
• D. Immediate surgical intervention

Answer: (A)

When a hematoma forms after arterial access, the first priority is to assess its size and track any change over time. Marking the edges and documenting the shape provides a clear baseline so you can detect expansion quickly. This noninvasive step helps guide subsequent actions, such as continuing careful observation, adjusting anticoagulation per protocol, or escalating care if the hematoma enlarges or if limb perfusion becomes compromised. Monitoring distal pulses is important for limb viability, but it doesn’t address the hematoma’s progression as directly as documenting its size. Massaging toward the incision site can worsen bleeding by dislodging clots and increasing the hematoma, so it should be avoided. Immediate surgical intervention is reserved for active, brisk bleeding with instability or a rapidly expanding hematoma that requires operative control.
