387. Rest of Mind and Body. The great importance of rest for the sick is not so generally recognized as its value warrants. If it is worry and not work that breaks down the mental and physical health of the well, how much more important is it that the minds and bodies of the sick should be kept at rest, free from worry and excitement! Hence the skilled nurse does her best to aid in restoring the sick to a condition of health by securing for her patient complete rest both of mind and body. To this end, she skillfully removes all minor causes of alarm, irritation, or worry. There are numberless ways in which this may be done of which space does not allow even mention. Details apparently trifling, as noiseless shoes, quietness, wearing garments that do not rustle, use of small pillows of different sizes, and countless other small things that make up the refinement of modern nursing, play an important part in building up the impaired tissues of the sick. 388. Care of Infectious and Contagious Diseases. There are certain diseases which are known to be infectious and can be communicated from one person to another, either by direct contact, through the medium of the atmosphere, or otherwise. Of the more prevalent infectious and contagious diseases are _scarlet fever, diphtheria, erysipelas, measles_, and _typhoid fever_. Considerations of health demand that a person suffering from any one of these diseases should be thoroughly isolated from all other members of the family. All that has been stated in regard to general nursing in previous sections of this chapter, applies, of course, to nursing infectious and contagious diseases. In addition to these certain special directions must be always kept in mind. Upon the nurse, or the person having the immediate charge of the patient, rests the responsibility of preventing the spread of infectious diseases. The importance must be fully understood of carrying out in every detail the measures calculated to check the spread or compass the destruction of the germs of disease. 389. Hints on Nursing Infectious and Contagious Diseases. Strip the room of superfluous rugs, carpets, furniture, etc. Isolate two rooms, if possible, and have these, if convenient, at the top of the house. Tack sheets, wet in some proper disinfectant, to the outer frame of the sick-room door. Boil these sheets every third day. In case of diseases to which young folks are very susceptible, send the children away, if possible, to other houses where there are no children.
