Identifying EKG Artifacts and Corrections

Which of the following is a common characteristic of muscle artifacts on an EKG?

• Regular, evenly spaced waves

• Irregular, erratic spikes

• Flat line with no activity

• Consistent, low amplitude waves

What is a common source of electrical interference that can affect an EKG reading?

• Patient's breathing

• Nearby electronic devices

• Patient's heart rate

• Room temperature

How can poor electrode placement be identified on an EKG?

• Consistent baseline with no deviations

• Sudden drops in amplitude

• Inverted or missing P waves

• Regular, rhythmic patterns

Which of the following is a method to correct baseline wander in an EKG?

• Increase the paper speed

• Use a high-pass filter

• Decrease the gain

• Apply more gel to electrodes

What effect does patient movement have on an EKG reading?

• It causes a flat line

• It introduces noise and artifacts

• It enhances the signal clarity

• It stabilizes the baseline

Which of the following actions can help reduce muscle artifacts during an EKG?

• Asking the patient to hold their breath

• Ensuring the patient is relaxed and still

• Increasing the room temperature

• Using a lower frequency filter

What is a common corrective measure for electrical interference in EKGs?

• Moving the patient to a different room

• Turning off nearby electronic devices

• Increasing the electrode size

• Changing the EKG paper speed

How can poor electrode placement be corrected to improve EKG accuracy?

• By using more electrodes

• By repositioning electrodes to standard anatomical locations

• By increasing the gain

• By using a different EKG machine

Which of the following is a sign of baseline wander on an EKG?

• Sharp, narrow spikes

• Slow, undulating shifts in the baseline

• Consistent, high amplitude waves

• Flat line with no activity

What is a practical step to minimize patient movement artifacts during an EKG?

• Asking the patient to talk during the procedure

• Ensuring the patient is comfortably positioned

• Increasing the EKG machine's sensitivity

• Using a higher frequency filter
