is too narrow for the patient’s arm circumference. Which of the following
results should the nurse expect?
A. A reading that is unaffected by the cuff size
B. A falsely low blood pressure reading
C. A falsely elevated blood pressure reading
D. An inability to auscultate Korotkoff sounds
Answer: C
Rationale: A cuff that is too small or too narrow causes the bladder to be inflated more to
compress the artery, resulting in a falsely high blood pressure reading.
2. The nurse is caring for a patient diagnosed with Clostridium difficile. Which
