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 obtain a blood pressure reading using only the left extremity from a client who has a right upper extremity arteriovenous fistula. An arteriovenous fistula is a surgical connection between an artery and a vein that is created for hemodialysis access.
Measuring blood pressure on the arm with an arteriovenous fistula can cause damage to the fistula, reduce blood flow, and increase the risk of infection or thrombosis. Therefore, blood pressure should be measured on the opposite arm or on another site such as the leg.
Correct Answer is B
Explanation
The client should expect less than 25 mL of secretions per day in the drainage devices before they are removed, usually within 7 to 10 days after surgery. This indicates that the wound is healing and there is no excessive fluid accumulation in the surgical site. The other statements are incorrect and indicate a need for further teaching. The client should not wait 2 months before additional saline can be added to the breast expander, as this may delay the reconstruction process and increase the risk of infection or contracture.
The client should keep the left arm elevated on a pillow and avoid flexing it at the elbow, as this may impair lymphatic drainage and cause edema or pain. The client should perform gentle range-of-motion exercises with the left arm and avoid lifting heavy objects such as a 15-pound weight, as this may strain the incision or cause bleeding.
