Question

ECG technicians take precautions by

protecting themselves from diseased tissue.

covering parts of the body not being monitored with lead-lined blankets.

monitoring the patient's physical appearance, heart rate, skin temperature, and blood oxygen.

Answer 1

Briefly:

- Protecting themselves from diseased tissue — partly true (clarify): ECG technicians follow standard infection‑control precautions (hand hygiene, gloves, cleaning electrodes and leads, sometimes masks/gowns when indicated) to avoid exposure to blood or body fluids. The phrasing “diseased tissue” is misleading.

- Covering parts of the body not being monitored with lead‑lined blankets — false. Lead shielding is used in radiology/X‑ray, not for ECGs.

- Monitoring the patient's physical appearance, heart rate, skin temperature, and blood oxygen — mostly true with caveats: ECG techs observe the patient’s appearance and pain/label symptoms and record heart rate; during stress testing or when clinically indicated they also monitor blood pressure and often pulse oximetry. Skin temperature is not routinely a primary parameter but may be noted.

If you want, I can list the usual precautions and monitoring tasks ECG technicians routinely perform.
