CHAPTER IX
The Hikers
THE assistant nurse had very little time for the next lesson in the boys’ class, so she gave them only notes in the morning, promising the practice games at four o’clock in the afternoon. After telling them of this plan, she began the lesson.
“Probably you boys have never thought of the fact that the little pipes and larger tubes which carry the blood may be broken under the skin,” Miss Helpem said. “When the blood gathers in dark purplish spots underneath the unbroken skin, you have what is called a bruise or contusion.
Bruises (Contusions)
(See [Reference List])
“Black and blue” spots which result from bleeding under the skin are caused by falls or blows, or pinching (as in door or window).
Treatment:
Apply cold water or ice wrapped in a cloth, or an ice bag, or bathe with half water and half alcohol, or witch hazel, or arnica.
If an arm or finger, hold up over the head.
