When taking frequent vital signs on a postoperative patient, the NAP uses an electronic blood pressure machine and obtains a blood pressure of 188/70 mm Hg. She appropriately notifies the nurse of the value, and the nurse checks the patient. The patient is awake and alert and offers no complaints. The nurse uses a stethoscope and obtains a blood pressure of 112/80 mm Hg. How does the nurse explain the difference in values?

When taking frequent vital signs on a postoperative patient, the NAP uses an electronic blood pressure machine and obtains a blood pressure of 188/70 mm Hg. She appropriately notifies the nurse of the value, and the nurse checks the patient. The patient is awake and alert and offers no complaints. The nurse uses a stethoscope and obtains a blood pressure of 112/80 mm Hg. How does the nurse explain the difference in values?

Correct Answer: A

Rationale: A cuff that is too small overestimates BP (188/70 vs. 112/80) because it requires more pressure to compress the artery, leading to falsely high readings. A loose cuff or one over clothing typically underestimates BP; a large cuff might slightly underestimate but not to this degree.
