The question often arises as to whether this visiting work is suitable employment for arrested cases—for nurses who have had tuberculosis and recovered. It is not suitable. It is far too hard and trying, for it must be done day in and day out, at all seasons and in all weathers, and involves severe physical strain. For that reason it is not proper occupation for one whose health is in any way precarious. The danger of relapse is too great. Nor should this work be done by those who are afraid of tuberculosis. If fear of tuberculosis develops after a nurse goes on duty, she should be released at once. Under such circumstances she cannot do good work, while to persuade her to remain on duty, contrary to her instincts, is a responsibility too grave for any one to assume. =Hours off Duty.= At this point we should like to speak of the nurse’s hours off duty, though strictly speaking they are not within our scope. As a rule, the hours on duty are eight—from 9 a.m. till 5 p.m., with an hour in the middle of the day for lunch. This is a long day, and at the end of it, any woman is in a condition of mental and physical fatigue. The constant nervous strain occasioned by contending with the ignorance and stubbornness which a nurse must encounter, is particularly wearing. The hours off duty are for recuperation from the day’s toil, and if this recuperation is insufficient, it will manifest itself in various ways. A tired nurse is of no use as a teacher—she cannot cope successfully with the obstinate wills of her patients, nor with the trying demands of the daily routine. Moreover, a physically tired person is one who offers ready soil for the development of tuberculosis. These two facts must be constantly borne in mind. Therefore we should like to impress upon all nurses who undertake this work that they must take excellent care of themselves. Rest, sleep, and food are the three essentials to good health, and any scheme of life which reduces these below a certain level is bound to lead to disaster. No one condemns reasonable pleasures, and in no other work is relaxation and recreation so much required, but one must be careful not to burn the candle at both ends. It is no part of the superintendent’s duties to regulate the life of her nurses outside of working hours, but when their life off duty diminishes their working ability, she is then called upon to interfere. Tuberculosis work is trying, serious, and difficult, and demands a high degree of mental and physical strength and freshness. If a nurse is not willing to give this, she should not undertake public health work.
