The nurse assesses a client with intermittent claudication who is receiving pentoxifylline. Which assessment should the nurse perform to determine the effectiveness of the medication?

Intermittent claudication is a condition in which there is pain in the legs due to reduced blood flow. Pentoxifylline is a medication that can improve blood flow by reducing the viscosity of the blood. Therefore, to determine the effectiveness of the medication in managing intermittent claudication, the nurse should monitor the client's pain level using a numeric pain scale. This will help to assess if the medication provides pain relief and improving the client's ability to walk without discomfort. Options a, b, and c are not relevant to the assessment of the effectiveness of pentoxifylline in managing intermittent claudication. ​​​​​​​
