What key concepts should be studied regarding sensitivity and
specificity? - ✔✔ANSWER ✔✔-Be able to calculate sensitivity
and specificity.
What is the formula for calculating sensitivity? - ✔✔ANSWER
✔✔-TP/(TP+FN), where TP is true positives and FN is false
negatives.
What does sensitivity refer to in diagnostic testing? -
✔✔ANSWER ✔✔-A test's ability to designate an individual with
a disease as positive.
Why are tests with high sensitivity ideal for screening? -
✔✔ANSWER ✔✔-They correctly identify patients who have the
disease, even at the cost of increased false positives.
What is the formula for calculating specificity? - ✔✔ANSWER
✔✔-TN/(TN + FP), where TN is true negatives and FP is false
positives.
,What does specificity refer to in diagnostic testing? -
✔✔ANSWER ✔✔-The ability of a test to recognize patients who
do not have the disease.
What is the SPIN rule in clinical diagnosis? - ✔✔ANSWER ✔✔-A
highly specific test, when positive, is useful for confirming a
diagnosis.
What is the application of the SPIN rule? - ✔✔ANSWER ✔✔-If a
test has high specificity and is positive, the condition is likely
present.
What is the SNOUT rule in clinical diagnosis? - ✔✔ANSWER
✔✔-A highly sensitive test, when negative, is useful for ruling
out a diagnosis.
What is the application of the SNOUT rule? - ✔✔ANSWER ✔✔-
If a test has high sensitivity and is negative, the condition is
likely absent.
, What is the summary of the SPIN rule? - ✔✔ANSWER ✔✔-High
specificity → Positive result → Confirms diagnosis.
What is the summary of the SNOUT rule? - ✔✔ANSWER ✔✔-
High sensitivity → Negative result → Rules out diagnosis.
What is the importance of understanding SPIN and SNOUT
rules? - ✔✔ANSWER ✔✔-They help guide healthcare providers
in making informed decisions about patient care.
What does the SNAPPS method refer to? - ✔✔ANSWER ✔✔-A
commonly used method in clinical reasoning that follows the
mnemonic SNAPPS.

findings, narrow the differential diagnosis, analyze the
differential, probe the preceptor with questions, plan
management, and select an issue for self-directed learning.
What is a differential diagnosis? - ✔✔ANSWER ✔✔-The ability
to distinguish a disease or condition from others that present
with similar signs, symptoms, or diagnostic test results.
