A nurse is planning to obtain a 12-lead ECG for a client who has a history of cardiac dysrhythmias. Which of the following actions should the nurse plan to take?

It is important for the client to remain still during the recording of a 12-lead ECG to obtain accurate and clear readings of the heart's electrical activity. The orthopneic position (sitting upright and leaning forward) is typically used to help relieve shortness of breath in clients with respiratory distress and is not directly related to obtaining a 12-lead ECG. Attaching a blood pressure cuff is not necessary for obtaining a 12-lead ECG, as it measures blood pressure and not the electrical activity of the heart. A mild stinging sensation is not expected during the test. The electrodes used to record the ECG are typically adhesive and do not cause discomfort to the client
