A client with a history of a right radical mastectomy arrives on the postoperative unit following surgical repair of a fractured left radius and application of a short arm cast. Which action should the practical nurse implement while obtaining the client's blood pressure (BP)?

Choice A reason: Checking mucous membranes can provide information about the client's hydration status. Dry mucous membranes can be a sign of dehydration, which may contribute to decreased urine output. This assessment is important to determine whether the client has adequate fluid balance.
Choice B reason: Ensuring that the catheter tubing is straight is essential to confirm that there are no kinks or obstructions that could be causing the reduced urine flow. Any obstruction in the catheter tubing could lead to a sudden decrease in urine output, and this check helps ensure patency.
Choice C reason: Auscultating lung sounds is crucial to assess for fluid overload or pulmonary complications, which can be associated with renal transplant patients. Abnormal lung sounds could indicate issues that may indirectly affect urine output and overall kidney function.
Choice D reason: Determining the dryness of bed linens helps assess whether the client might have experienced a leakage of urine outside the catheter system. If the bed linens are wet, it could indicate an issue with the catheter or bladder function that needs to be addressed.
Choice E reason: Irrigating the catheter to assess patency is a direct method to determine whether there is any blockage or obstruction in the catheter. This procedure helps ensure that the catheter is functioning correctly and allows for appropriate urine drainage.

Choice A reason: Bathing the wound daily with soap and water is a common practice to maintain cleanliness and prevent infection in a wound. However, this is not the immediate priority in this scenario. The presence of a dusky color on the left foot indicates potential vascular compromise, which needs to be assessed first to ensure adequate blood flow to the affected area. Cleaning the wound can be done subsequently, but checking circulation is critical to address any immediate risks.
Choice B reason: Recording the color and temperature of the leg is an important assessment step to monitor the client's condition. These observations can provide valuable information about the client's peripheral circulation and skin condition. However, while this should be done as part of the overall assessment, it is not the most immediate action. Checking the pulses will give more direct information about the blood supply to the affected area, which is crucial for identifying any urgent circulatory issues.
Choice C reason: Performing dorsiflexion and extension exercises can help maintain joint mobility and muscle strength in clients with diabetes. However, it is not the first intervention that should be implemented in this scenario. Before recommending exercises, it is essential to assess the vascular status of the client's foot. Exercises may not be appropriate if there is significant circulatory compromise, and could potentially cause further harm.
Choice D reason: Checking the client's dorsalis pedis and posterior tibialis pulse points is the most critical first intervention. The dusky color of the foot suggests a possible issue with blood flow. By assessing the pulses in the foot, the practical nurse can determine if there is adequate perfusion to the area. If the pulses are weak or absent, it may indicate peripheral artery disease or another vascular issue that requires immediate medical attention. Prompt identification and intervention are crucial to prevent further complications, such as tissue necrosis or limb-threatening ischemia.
