A client in outpatient cardiac rehabilitation is doing graded upper-body activity. Resting blood pressure was 128/80 mm Hg. As the workload increases, the COTA measures 112/78 mm Hg, and the client reports feeling lightheaded. What should the COTA do?
Show answer & explanation
Answer: D
Continue at the same level because diastolic pressure is stable: A drop in systolic pressure during exercise is abnormal even when diastolic pressure does not change.
Increase the workload slightly to raise the heart rate: Raising the workload when the cardiovascular response is already abnormal increases the risk of an adverse cardiac event.
Have the client rest and recheck pressure after 10 minutes: Resting is appropriate, but this abnormal response must also be reported to the OTR and medical team.
Stop the activity and report the response to the OTR and team: Correct. A systolic drop of more than 10 mm Hg with increasing workload, especially with symptoms, is a criterion to stop activity.
Normal exercise response: systolic BP rises with workload. A systolic drop of more than 10 mm Hg, or symptoms such as lightheadedness, means stop and report.
