A nurse is assisting in the care of a client who has a pulmonary embolism and is experiencing dyspnea. Which of the following actions should the nurse take first?

The client had a right radical mastectomy, which can lead to lymphedema, a buildup of fluid that can cause swelling in the arm. Using the client's left arm to obtain blood samples can help prevent injury to the affected arm and reduce the risk of lymphedema. Obtaining blood pressure readings with the client's left arm is also recommended. Range-of-motion exercises are important to prevent stiffness, and elevating the affected arm can help reduce swelling.

A: Obtaining blood pressure readings with the client's right arm can cause injury and increase the risk of lymphedema.

B: Limiting range-of-motion exercises can lead to stiffness and may not prevent lymphedema.

C: Keeping both arms below the level of the client's heart can help reduce swelling, but does not directly prevent lymphedema.

Red streaks along the incision. This is a possible sign of infection and should be reported to the healthcare provider. A temperature of 37.2°C (99°F) is within the normal range and does not require reporting. Serosanguineous drainage at the incision site is normal within the first few days postoperatively. Hypoactive bowel sounds in all four quadrants can indicate ileus, which is a possible complication following abdominal surgery, but it is not an immediate concern and can be monitored unless other symptoms arise.

Choice A: A temperature of 37.2°C (99°F) is within the normal range and does not require reporting.

Choice B: Serosanguineous drainage at the incision site is normal within the first few days postoperatively.

Choice D: Hypoactive bowel sounds in all four quadrants can indicate ileus, which is a possible complication following abdominal surgery, but it is not an immediate concern and can be monitored unless other symptoms arise.
