Quizplus · Accepted Answer

Capillary stick blood samples involve the use of capillary action to draw blood into a small tube. Absorbent humidifier wicks use capillary action to draw water from a reservoir and distribute it through the air as a fine mist. Certain surgical dressings use capillary action to wick away excess fluids from wounds, promoting healing. Therefore, all three options are good clinical examples of the principle of capillary action.
