Final answer:
To differentiate between an arterial ulcer and a venous stasis ulcer, the nurse can use evaluations of peripheral pulses, measurement of ankle circumference, and inspection of wound color and drainage.
Step-by-step explanation:
In order to differentiate between an arterial ulcer and a venous stasis ulcer, the nurse can use the following focused assessments:
- Evaluation of peripheral pulses: Arterial ulcers are often associated with decreased or absent peripheral pulses, whereas venous stasis ulcers typically have normal pulses.
- Measurement of ankle circumference: Arterial ulcers are more likely to result in decreased ankle circumference, while venous stasis ulcers may cause normal or increased ankle circumference due to edema.
- Inspection of wound color and drainage: Arterial ulcers often have a pale or necrotic appearance, and the drainage may be minimal. Venous stasis ulcers usually have a reddish or brownish color, and the drainage may be moderate to heavy.
