Again, there are physicians who do not object to the nurse on this score, but who resent her as a subtle menace to their practice. They feel that if a layman is able to preach rest, fresh air, and food, and distribute prophylactic supplies, that the ground will be cut out from under them, and that they will lose a chronic and fairly lucrative class of patients. As a matter of fact, the physician who preaches this simple doctrine has nothing to fear from the tuberculosis nurse—if her words echo his they only add force. There are other physicians, however, who have received an inferior medical education; they are neither sure of themselves, nor able to diagnose tuberculosis until it is in an advanced state. These object to the nurse on the ground, implied rather than expressed, that she is supervising and criticizing their work, and this self-consciousness often takes the form of a violent antagonism. It is always the badly trained physician who fears the well-trained nurse. Furthermore, there are certain practitioners who frankly exploit their patients. They may be competent enough but they are in medicine to make a living, and are often brutally unethical as to how this is done. If through self-interest it seem best to them to withhold from the patient the nature of his disease, they do not hesitate to do so, regardless of the danger to which others may be exposed. By a strange paradox, the same profession which gives us the noblest, the most unselfish workers in the interests of public health, also gives us its most implacable enemies. However, the new nurse must call upon all the physicians of the community, and endeavour to obtain their assistance and support. But, for the reasons mentioned, she must not be discouraged if she is not always cordially received by them. There will always be among them many who are enlightened and progressive, and who will assist generously in the anti-tuberculosis campaign. If a community can boast of only one or two such men, even, success is assured. And later on, as the nurse progresses quietly in her work, she will come into contact with other doctors, who promise her aid, but ignore their promises because they think she is trying to steal away their patients. As it gradually dawns on them that this is not the case, their opposition will wear off. To conquer this prejudice as soon as possible is part of the nurse’s work.
