●● An EKG technician is preparing to perform an exercise stress test on
a patient. Which of the following findings in a patient's medical history
would prevent the patient from participating in an exercise stress test?
Answer: Congestive heart failure
●● An EKG technician should recognize that which of the following
situations would result in wandering baseline artifact on an EKG
tracing?
Answer: Loose electrodes

least how many seconds long to accurately identify rate and rhythm?
Answer: 6 seconds
,●● An EKG technician in an outpatient facility is obtaining a patient's
vital signs and is having trouble visualizing the patient's chest
movement. Which of the following actions should the technician take to
obtain an accurate respiratory rate for the patient?
