A nurse is preparing to perform a 12-lead electrocardiogram (ECG). Which of the following instructions should the nurse provide to the client?
Correct answer
A
Rationale
A 12-lead ECG requires electrode placement on the chest and limbs to record heart activity, making this the key instruction. Remaining still (B) and short duration (D) are true but secondary. Slight pressure (C) may occur, but itÔÇÖs not the primary focus. Electrode placement is procedural core.
