During your routine check of the clinic's electronic blood pressure monitor, you notice that the readings have been consistently higher when compared to a recently calibrated manual sphygmomanometer for the same patient. What should be your first action to address this issue?
Ignore the discrepancy as long as the electronic blood pressure monitor functions and turns on
Continue to use the electronic blood pressure monitor but record that readings may be higher
Remove the electronic blood pressure monitor from service and have it calibrated
Check if the electronic blood pressure monitor's batteries need replacement
