EKG certification Certification EKG Patient Preparation & Clinical Procedures 3

Question 1

What is the primary reason chest hair may need to be clipped before EKG electrode placement?

Accepted Answer

Chest hair prevents proper electrode-skin contact, increasing impedance and artifact

Answer

Chest hair prevents full skin-to-electrode contact, increasing impedance and causing artifact; clipping (not shaving) the minimal area needed improves signal quality.

Question 2

Which statement best describes the role of the EKG technician in patient confidentiality?

Accepted Answer

Technicians must protect patient information and only share results with authorized personnel per HIPAA guidelines

Answer

Under HIPAA, EKG technicians must safeguard all patient health information and share results only with authorized members of the care team.

Question 3

When performing a 12-lead EKG on a pediatric patient, which adaptation is most appropriate?

Accepted Answer

Use smaller pediatric electrodes to fit the smaller chest and limb size

Answer

Pediatric patients require smaller electrodes designed for their body size to ensure proper electrode-to-skin contact and accurate waveform capture.

Question 4

After completing a 12-lead EKG, how should the technician dispose of used single-use electrodes?

Accepted Answer

Dispose of them in a standard medical waste (biohazard) container or regular trash per facility policy

Answer

Single-use electrodes are considered medical waste; disposal follows facility and local regulations, typically in standard waste or biohazard bags depending on blood/body fluid exposure.

Question 5

A patient's EKG shows an unexpectedly long QTc interval. What is the EKG technician's responsibility?

Accepted Answer

Immediately notify the appropriate clinical staff or ordering provider of the abnormal finding

Answer

EKG technicians are not authorized to diagnose, but they are responsible for promptly communicating critical or unexpected findings to the appropriate clinical personnel.
