A patient comes to the walk-in clinic with complaints of pain in his foot following stepping on a roofing nail a "couple of days ago." The patient has a red streak running up his leg. What would the nurse suspect?
A) Cellulitis
B) A minor superficial skin irritation.
C) Elephantiasis
D) Lymphangitis
Ans: D
Feedback: Lymphangitis is an acute inflammation of the lymphatic channels. It arises most commonly from a focus of infection in an extremity. Usually, the infectious organism is hemolytic Streptococcus. The characteristic red streaks that extend up the arm or the leg from an infected wound outline the course of the lymphatic vessels as they drain. Option A is incorrect; cellulitis is caused by bacteria, which cause a generalized edema in the subcutaneous tissues surrounding the affected area. Option B is incorrect; a minor superficial skin irritation would not present with red streaks in the lymphatic channels. Option C is incorrect; elephantiasis is transmitted by mosquitoes that carry a parasitic worm larvae; the parasites obstruct the lymphatic channels and results in gross enlargement of the limbs.
