What is the purpose of using conductive gel or gel-based electrodes during an EKG?
Answer: To reduce skin resistance and improve electrical signal transmission
Conductive gel lowers skin impedance, allowing the EKG machine to detect weak cardiac electrical signals accurately.
Which statement about patient consent for a routine EKG is correct?
Answer: Implied consent is generally acceptable for routine diagnostic EKGs
Routine non-invasive procedures such as EKGs typically fall under implied consent when the patient cooperates with the procedure.
A patient reports chest pain during EKG preparation. What should the EKG technician do?
Answer: Stop the procedure, activate emergency protocols, and notify clinical staff immediately
Chest pain is a potential cardiac emergency; the technician must notify clinical staff and activate emergency protocols immediately.
To reduce somatic (muscle) artifact on an EKG tracing, the technician should instruct the patient to:
Answer: Hold their breath and remain still during the recording
Remaining still and holding a normal breath during recording minimizes skeletal muscle electrical interference.
When removing pre-gelled disposable electrodes after an EKG, the technician should:
Answer: Peel slowly while supporting the skin, especially in elderly or fragile patients
Slow, controlled removal while supporting the skin prevents skin tears, particularly in patients with fragile or elderly skin.
Which body landmark is used to locate the V4 precordial electrode placement?
Answer: Fifth intercostal space, left midclavicular line
V4 is placed at the fifth intercostal space at the left midclavicular line, which is a key reference point for precordial lead placement.
