Question

Use the EKG below and a compass in your lab manual to determine the patient's MEA value. Choose your answers from the drop-down choices: The MEA approximates select and the correct units used are select. a) The MEA approximates the heart rate, and the correct units are beats per minute. b) The MEA approximates the cardiac axis, and the correct units are degrees. c) The MEA approximates the blood pressure, and the correct units are mmHg. d) The MEA approximates the respiratory rate, and the correct units are breaths per minute.

Answer 1

The MEA value from an EKG represents the mean electrical axis of the heart and is measured in degrees, not related to heart rate, blood pressure, or respiratory rate.

Step-by-step explanation:

The question asks about determining the MEA from an EKG reading and understanding its correct units. MEA stands for mean electrical axis, which reflects the overall direction of electrical activity in the heart during a heartbeat. It is not related to the heart rate, blood pressure, or respiratory rate. Therefore, the correct answer from the provided options is:

b) The MEA approximates the cardiac axis, and the correct units are degrees.
