Question

a friend has a severe cut on her arm. after a few days of caring for the cut, your friend says she is not feeling well and shows you red lines starting at the cut and progressing up her arm. she asks your advice on what to do next. you should tell your friend to—
contact her physician to determine further care.
all of the above
soak the wound in hot water to stop the red streaks.
continue her current care; the streaks mean it is getting better.

Explanation:

Red streaks starting at a wound and progressing up the arm can indicate an infection spreading. Soaking in hot water won't stop an infection (it might even be harmful if there's an infection). Continuing current care when there are signs of infection (feeling unwell, red streaks) is not appropriate as the situation has worsened. Contacting a physician is the correct course of action as a medical professional can properly diagnose (e.g., if it's cellulitis or lymphangitis) and provide appropriate treatment (like antibiotics if it's an infection). Since only "Contact her physician to determine further care" is a valid option (the other options "Soak..." and "Continue..." are incorrect, so "All of the above" is also wrong).

Answer:

Contact her physician to determine further care.
