Final answer:
A CPCT who detects a U wave in the presence of chest pain should inform a physician or healthcare provider immediately for further evaluation, as it may indicate an underlying cardiac condition.
Step-by-step explanation:
If a Cardiopulmonary Technician (CPCT) detects a U wave on an electrocardiogram (ECG) and a patient reports chest pain and discomfort, the appropriate action would be for the technician to promptly inform the attending physician or a qualified healthcare provider. The presence of U waves can be normal in some cases, but when associated with symptoms such as chest pain, it may indicate an underlying cardiac condition such as hypokalemia, hyperthyroidism, or heart disease. The reported symptoms alongside an abnormal ECG finding warrant further medical evaluation.
The steps described in the question related to measuring blood pressure by inflating a cuff and listening for Korotkoff sounds are correct, but they are not directly related to the action a CPCT should take in response to a U wave and chest pain. This process is part of a routine blood pressure measurement.
Given the clinical focus on interpreting ECG results and connecting them with patient symptoms, the technician's role in this scenario is to communicate findings to the healthcare team, facilitate further diagnostic procedures, and ensure the patient receives the necessary medical attention swiftly.
