Final answer:
The correct information regarding limb leads and electrodes in EKG recordings is as follows:
Limb leads are designated as I, II, and III, with corresponding electrodes on the right arm, left leg, and left arm. Therefore, the correct option is 3.
Step-by-step explanation:
This configuration makes it possible to measure the electrical activity of the heart from several angles. Proper placement of electrodes on the limbs, rather than the chest, is necessary for accurate electrical signal capture in limb leads.
Precordial (chest) leads are usually connected with electrode placement on the chest.
To provide accurate assessments of heart activity and acquire exact EKG recordings, it is imperative to comprehend the correct positioning of limb leads and electrodes.
Therefore, the correct option is 3.
Your question is incomplete, most probably the complete question is:
A medical assistant is preparing to perform an EKG recording on a patient. The assistant should recognize that which of the following information is true of limb leads and electrodes?
- Limb leads are recorded on the chest, while electrodes are placed on the limbs.
- Limb leads and electrodes are interchangeable terms in the context of EKG recordings.
- Limb leads are designated as I, II, and III, with corresponding electrodes on the right arm, left leg, and left arm.
- Electrodes for limb leads should be placed on the chest for optimal EKG recording accuracy.
