Final answer:
The nurse practitioner should assess for the possibility of a lipid disorder and order a fasting lipid panel to determine the patient's cholesterol and triglyceride levels.
Step-by-step explanation:
The nurse practitioner should assess for the possibility of a lipid disorder and order a fasting lipid panel.
The raised, yellow-colored soft plaques on the patient's finger could suggest the presence of a condition called xanthomas, which are deposits of cholesterol and other fats under the skin. Xanthomas can occur in people with lipid disorders, such as hyperlipidemia.
Ordering a fasting lipid panel will help determine the patient's cholesterol and triglyceride levels and provide information about their lipid profile, which can assist in diagnosing a lipid disorder.
