Questions & Verified Answers
1. Which component of the OLD CARTS acronym refers to what the patient was doing when the
pain started?
A. Duration
B. Onset
C. Character
D. Location
Answer: B
Rationale: Onset in the OLD CARTS acronym addresses when the symptom started and what the patient was
doing at the time of commencement. Applying this knowledge in clinical settings supports safe, evidence-based
practice and improves patient outcomes. This is an important clinical concept because selecting the correct
answer (B) requires understanding both the pathophysiology and the practical nursing implications.
2. In the SOAP note format, where would the clinician document the patient’s physical
examination findings?
A. Objective
B. Subjective
C. Assessment
D. Plan
Answer: A
Rationale: The Objective section includes physical exam findings, vital signs, and laboratory or diagnostic
results. Applying this knowledge in clinical settings supports safe, evidence-based practice and improves
patient outcomes. This is an important clinical concept because selecting the correct answer (A) requires
understanding both the pathophysiology and the practical nursing implications.
3. What is the primary purpose of a differential diagnosis?
A. To confirm a single suspected condition immediately
B. To provide a summary of the patient’s past medical history
C. To document the treatment plan for the patient
D. To list all possible diseases that could cause the patient’s symptoms
Answer: D
Rationale: A differential diagnosis is a systematic method used to identify the condition, syndrome, or disorder
causing a patient’s signs and symptoms by considering all possibilities. This is an important clinical concept
because selecting the correct answer (D) requires understanding both the pathophysiology and the practical
nursing implications.

4. Sensitivity in a diagnostic test refers to the ability of the test to correctly identify:
A. Those without the disease
B. The severity of the disease
C. Those with the disease
D. The cost-effectiveness of the test
Answer: C
Rationale: Sensitivity is the proportion of true positives; it measures the test’s ability to identify those who
actually have the disease. This is an important clinical concept because selecting the correct answer (C)
requires understanding both the pathophysiology and the practical nursing implications. Recognizing this
principle allows the nurse to prioritize care, anticipate complications, and provide accurate patient education.
5. Specificity in a diagnostic test refers to the ability of the test to correctly identify:
A. Those without the disease
B. The prevalence of the disease
C. Those with the disease
D. The incubation period of the disease
Answer: A
Rationale: Specificity is the proportion of true negatives; it measures the test’s ability to identify those who do
not have the disease. Exam questions often test the ability to distinguish this concept from closely related
distractors, making a clear rationale essential for mastery. Applying this knowledge in clinical settings supports
safe, evidence-based practice and improves patient outcomes.
6. Which Centor criterion is worth one point in evaluating a patient for Streptococcal
pharyngitis?
A. Presence of a cough
B. Absence of a cough
C. Age over 45 years
D. Presence of nasal congestion
Answer: B
Rationale: The absence of a cough is one of the four original Centor criteria, indicating a higher likelihood of
bacterial rather than viral infection. Recognizing this principle allows the nurse to prioritize care, anticipate
complications, and provide accurate patient education. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery.
