Which of the following observations helps the nurse in determining adequate oxygenation?

C) Pink nail beds
D) Capillary refill time

Question

Quizplus · Accepted Answer

Pink nail beds indicate adequate oxygenation as the blood carrying oxygen appears red and is readily visible through the nail bed. The appearance of the lunula (half-moon-shaped white area at the base of the nail) and hard keratin (tough protein that makes up nails) are not related to oxygenation status. Capillary refill time can provide information on peripheral circulation, but is not specific to oxygenation status.
