Which platelet count is described in the notes as a concern for thrombocytopenia in relation to tPA safety?

• A. 50,000
• B. Greater than 100,000
• C. 100,000
• D. 400,000

Answer: (B)

Thombolytic therapy like tPA carries a bleeding risk, so platelet number matters. Thrombocytopenia means too few platelets, which increases bleeding risk and is a safety concern when considering tPA. The usual rule is that platelet counts must be around or above 100,000 per microliter to be considered safe for tPA; counts below that threshold signal thrombocytopenia and raise the safety concern. Among the values given, a count such as 50,000 would clearly be described as thrombocytopenia and a safety issue with tPA. A count of 100,000 is at the cutoff, and anything above that generally reduces the concern related to platelet-related bleeding risk. If the notes phrase the threshold as “greater than 100,000,” that wording is pointing to the safer, above-threshold range rather than the thrombocytopenia concern itself. The key idea is the 100,000 threshold guiding whether tPA can be safely used.
