A nurse is admitting a client who reports chest pain and has been placed on a telemetry monitor. Which of the following should the nurse analyze to determine whether the client is experiencing a myocardial infarction?
Twave
Ssegment
QRS duration
PR interval
The Correct Answer is B
The Ssegment is the portion of an electrocardiogram (ECG) that represents early ventricular repolarization, which occurs after ventricular contraction and before ventricular relaxation. The Ssegment can be elevated or depressed in cases of myocardial infarction (MI), indicating ischemia or injury to the myocardium due to reduced blood flow or oxygen supply.

Correct Answer is B
Explanation
The nurse should consult the client before approaching the dog, as the service animal is working and may have specific instructions from the handler on how to interact with others. The nurse should respect the client's autonomy and preferences regarding their service animal and not interfere with their bond or function.
Correct Answer is A
Explanation
The nurse's priority is to ensure that the client has given informed consent for the surgery, which requires that the client is competent and understands the risks and benefits of the procedure. A client with a high blood alcohol level may not have the mental capacity to consent and may need a legal representative or a court order to proceed with the surgery.
The other actions are important but not as urgent as obtaining consent.
