The Nurse in an Outpatient Clinic Obtains a Blood Pressure

The nurse in an outpatient clinic obtains a blood pressure of 190/88 mm Hg on a patient diagnosed with high blood pressure. The patient tells the nurse, "My blood pressure medicine is really expensive. Do you think I really need it?" The nurse assumes the patient is not taking the medication based on the blood pressure result and the patient's statement and chooses noncompliance as a diagnostic label. The action by the nurse is an example of:

A) clustering unrelated data in the diagnostic statement.
B) selecting erroneous data for use in the diagnostic statement.
C) using medical diagnoses in the diagnostic statement.
D) identifying multiple problems within one diagnostic statement.
