A client with idiopathic thrombocytopenic purpura (ITP) should report possible small‑vessel clotting when which finding is assessed?

• A. Petechiae on the upper chest
• B. Hypotension
• C. Cyanotic nail beds
• D. Severe headache

Answer: (C)

In this scenario, the key idea is that microvascular clotting would impair blood flow to distal tissues. If small vessels are occluded, oxygen delivery to the extremities can drop, causing cyanosis of the nail beds. That bluish discoloration reflects poor perfusion from microthrombi in the small vessels, which is the sign you’d look for when considering a thrombotic process in a patient with ITP.

Petechiae, a common finding in ITP, result from bleeding due to low platelets, not from clotting. Hypotension points to significant blood loss or another severe process, not clot formation in small vessels. Severe headache could signal a hemorrhagic event such as intracranial bleeding rather than clotting in the microcirculation. So cyanotic nail beds best indicate possible small-vessel clotting in this context.
