How to Disinfect the Hands.--Any of the following solutions may be used for disinfection of the nurse's hands: Creolin, one teaspoonful to the quart of water; chloride of lime, one-half pound to a pail of water; formalin, thirty-two drops to a quart of water. A basin containing one of the above solutions should be constantly kept standing for the frequent disinfection of the nurse's hands. After disinfection, the hands should be washed in plain water and soap. Disinfection of Room Necessary.--The room in which a contagious patient is confined requires systematic attention on the part of the nurse. Every other day all flat or projecting surfaces should be disinfected. Mantels, window-sills, door knobs, picture moldings, furniture, chairs, and bed-railings, should be wiped with cloths moistened in a disinfecting solution. A suitable solution for this purpose is one containing one ounce of carbolic acid to the quart of water. How to Disinfect the Mouth and Nose.--In the course of all contagious diseases the mouth and throat of the patient and nurse should be thoroughly disinfected as a matter of routine. It should be done at least twice daily unless more frequent disinfection is called for because of the nature of the disease. In measles and diphtheria, for example, the nasal and throat conditions will undoubtedly call for more frequent and more thorough disinfection than twice daily. This may also apply to scarlet fever if the throat is involved as is often the case. Pocket handkerchiefs should never be used by a patient suffering from a contagious disease. The nose and mouth should be wiped with pieces of gauze or cheesecloth, cut into small squares for this purpose. These should be immediately burned after being used. To disinfect the throat, a solution of formalin, six drops to six ounces of water, is effective. To disinfect the nose, a solution of Glyco-Thymoline is suitable. These applications should be made by means of an atomizer, a different atomizer being used for the patient and nurse. Receptacle for the Sputum.--A cuspidor, or basin, should be constantly kept at the side of the bed in which the patient may conveniently expectorate. This utensil should contain the chloride of lime solution previously mentioned.
