Question

An ekg tech is monitoring a patient who is undergoing a stress test. Which of the following findings should indicate to the tech that the patient is experiencing an adverse reaction?

1. increase in bp
2. on oxygen sat of 95%
3. presence of sinus tach
4. report of tingling sensation in lower extremities

Answer 1

During a stress test, a report of tingling sensation in the lower extremities is a concerning sign that might indicate an adverse reaction. This, along with specific ECG changes like alterations in ST and Q components, should alert the EKG technician to possible myocardial infarction.

Step-by-step explanation:

During a stress test, an EKG technician should monitor for signs that may indicate the patient is experiencing an adverse reaction. Of the four options presented, the report of a tingling sensation in the lower extremities is most concerning and may suggest an adverse reaction. While increases in blood pressure and the presence of sinus tachycardia (sinus tach) can be normal responses to exercise, a tingling sensation could indicate a neurological issue or decreased circulation. An oxygen saturation (O2 sat) of 95% is generally considered normal. However, the technician should also be vigilant for ECG signs of myocardial infarction such as alterations in the ST and Q components, which could indicate a more serious condition like a ST-elevated myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI).
