A nurse is assessing a client who has heart failure and a new prescription for metoprolol. Which of the following findings should the nurse identify as an adverse effect of the medication?

Choice A reason: While requiring assistance with getting dressed is an important consideration in care planning, it is not the most immediate priority. The nurse should ensure that the client's basic needs are met, but this does not represent an acute medical concern.

Choice B reason: The client reporting numbness of the fingers of the left hand is the most urgent priority. Numbness can indicate neurovascular compromise or increased pressure within the cast, which could lead to further injury or complications such as compartment syndrome. Immediate assessment and intervention are required to prevent permanent damage.

Choice C reason: Itching of the left arm under the cast is a common complaint and can be uncomfortable for the client. However, it is not a priority over potential neurovascular compromise. The nurse can provide education on how to safely alleviate itching without compromising the integrity of the cast.

Choice D reason: Having a pillow under the left arm is part of proper positioning to reduce swelling and provide comfort. While it is a part of good nursing care, it is not a priority over signs of neurovascular compromise.

Choice A reason: Checking the client's blood pressure every 8 hours is important, but it is not as critical as monitoring urine output in the immediate postoperative period. Blood pressure should be monitored regularly, but changes in urine output can provide more immediate information about the new kidney's function.

Choice B reason: Monitoring for hypokalemia is important, as it can be a sign of acute rejection; however, hyperkalemia is more commonly associated with acute rejection due to the kidney's inability to excrete potassium. Therefore, while electrolyte monitoring is crucial, the focus is typically on hyperkalemia rather than hypokalemia.

Choice C reason: Assessing urine output hourly is essential for a client who has undergone a kidney transplant. Urine output is a direct indicator of the new kidney's function, and any significant decrease could indicate a complication such as acute rejection or obstruction.

Choice D reason: Administering opioids orally for pain management is part of postoperative care, but it is not the priority over monitoring urine output and kidney function.
