How should a nurse accurately assess for thrombophlebitis in a client with pain in the left lower leg?

The correct answer is to document daily calf circumference measurements. This is an effective method for assessing thrombophlebitis since one of the key signs of this condition is swelling in the affected extremity. By measuring the calf circumference daily, the nurse can monitor for any changes that may indicate the development of thrombophlebitis, such as increased swelling due to inflammation or the presence of a thrombus.

Measuring calf circumference provides a quantifiable way to observe changes over time, which can be critical for early detection and management of potential complications. It is important for the assessment to be systematic and consistent to ensure any alterations are noted and addressed promptly. Other options like palpating the skin or recording vital signs may not directly indicate the presence of thrombophlebitis and could overlook the specific physical changes, such as swelling, that are most indicative of this condition. While noting difficulty with ambulation can provide context about the patient’s condition, it does not offer specific, measurable data that would help in assessing for thrombophlebitis.
