ATI LPN Mental Health Exam IV Questions

Extract:


Question 1 of 5

A nurse is assisting with the care of a client who was admitted to the telemetry unit after experiencing chest pain, dyspnea, and diaphoresis. Which of the following ECG findings is a manifestation of acute myocardial infarction?

Correct Answer: D

Rationale: ST segment elevation is a key diagnostic sign of acute myocardial infarction (STEMI), indicating myocardial injury due to blocked coronary blood flow. A PR interval of 0.15 seconds is normal (0.12–0.20 seconds), as is a QRS interval of 0.08 seconds (0.06–0.10 seconds). A QT interval equal to the R-R interval is abnormal but not specific to myocardial infarction; it suggests prolonged repolarization, possibly from other causes.
