What is a characteristic of Type I HIT according to the description?

  1. Immediate therapy termination is required

  2. It is characterized by a gradual reduction in platelets

  3. It involves an acute fall in platelets

  4. It is less serious than Type II HIT

The correct answer is: It is characterized by a gradual reduction in platelets

A characteristic of Type I HIT, according to the description, is that it involves a gradual reduction in platelets. This means that the decrease in platelets typically occurs over a longer period of time compared to Type II HIT (answer C), which involves a more sudden and acute fall in platelets. Option A is incorrect because immediate therapy termination is not required for Type I HIT. Option D is incorrect because Type I HIT is not necessarily less serious than Type II HIT. Both forms of HIT can be serious and require prompt medical attention.
