Questions & Verified Answers
1. When using the SBAR communication tool, which information belongs in the ‘B’
(Background) section?
A. The patient’s current vital signs
B. The patient’s admitting diagnosis and medical history
C. The reason the nurse is calling the provider
D. The nurse’s recommendation for a change in treatment
Answer: B
Rationale: Background (B) includes the admitting diagnosis, relevant medical history, and summary of
treatment to date. Current vitals usually fall under Assessment (A). 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.
2. What is the most accurate method for assessing a patient’s heart rate if they have an
irregular rhythm?
A. Palpate the radial pulse for 30 seconds and multiply by 2
B. Auscultate the apical pulse for 60 seconds
C. Use a pulse oximeter for a quick reading
D. Palpate the carotid pulse for 15 seconds and multiply by 4
Answer: B
Rationale: For irregular rhythms, the apical pulse must be auscultated for a full minute to ensure accuracy.
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.
3. A nurse is measuring blood pressure using a cuff that is too small for the patient’s arm. How
will this affect the reading?
A. The reading will be falsely low
B. The reading will be falsely high
C. The reading will not be affected
D. Only the diastolic pressure will be inaccurate
Answer: B
Rationale: A blood pressure cuff that is too narrow or small will result in a falsely elevated reading.
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.

D. Justice
Answer: B
Rationale: Autonomy refers to the patient’s right to make their own healthcare decisions, even if the nurse
disagrees. 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.
5. When assessing orthostatic hypotension, which drop in systolic blood pressure indicates a
positive finding?
A. 5 mmHg
B. 10 mmHg
C. 20 mmHg
D. 15 mmHg
Answer: C
Rationale: Orthostatic hypotension is defined as a drop in systolic BP of at least 20 mmHg or a drop in diastolic
BP of at least 10 mmHg within 3 minutes of standing. 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 hand hygiene method is mandatory after caring for a patient with Clostridioides
difficile (C. diff)?
A. Alcohol-based hand rub
B. Hydrogen peroxide wipes
C. diff)?
D. Washing with soap and water
Answer: D
Rationale: Soap and water are required because alcohol-based rubs do not kill C. diff spores. 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 (D) requires understanding both the
pathophysiology and the practical nursing implications.
