85) You and another EMT are discussing a call he previously ran. The EMT said the patient had
classic chest pain symptoms and he treated it as a possible heart attack, but he later found out the

longer trust his judgment. How should you respond to his concerns?
A) Tell him that his misdiagnosis is a common EMT mistake caused by illusionary correlation.
B) Tell him that his misdiagnosis is a result of anchoring.
C) Tell him that his misdiagnosis is a result of confirmation bias.

86) You are on the scene in the bad part of town for an unresponsive 18-year-old type 1 diabetic
patient. His mother states that he is very noncompliant with his diabetes management and goes
unresponsive often due to low blood sugar. After performing the primary assessment, you believe
that this is the most likely cause of his unresponsiveness. However, after taking a capillary
glucose reading you are surprised to see that the patient's sugar level is normal. How will you
now determine the field impression?
A) Recognize that the mother was lying to you. The patient is not diabetic and you now must
assume that everything she told you is wrong.
B) You cannot make a correct diagnosis in the field because you cannot perform all the necessary
tests with your limited scope of practice.
C) Recognize that the mother is probably trying to protect her son from jail. Tell her that it is
critical that she tell you what drugs he actually took.

secondary assessment.
