The nurse is assessing bruising on an injured patient and the red color indicates a new bruise that is less than 2 hours old.
Hence option (a) is correct.
After a blunt force trauma, a fresh bruise normally appears red and frequently takes on a purple or purple-blue color 12 to 36 hours later.
Bruises (and ecchymoses) usually start out purple-blue, then turn bluish-green, then greenish-brown, then brownish-yellow, before disappearing altogether.
Hemoglobin, an iron-rich component in your blood, disintegrates into other substances as you heal. Your bruise changes color as a result of this process:
• Immediately following an injury, it is typically red.
• It turns purplish or black and blue after a day or two.
• It might turn yellow or green in 5 to 10 days.
• It turns yellowy-brown or light brown after 10 to 14 days.
It should completely go in around two weeks.
