One out of every ten British nurses considers nurse-patient sex in hospitals to be acceptable. One out of six actually knows about at least one co-worker who has or has had sex with a patient. These are the stunning facts, published in "Nursing Times" today. British hospitals recently tightened the rules about nurse-patient relationships. Such relationships - even with former patients - are considered unacceptable and can result in disciplinary action and even job loss. Still - according to the survey - many British nurses are willing to take their romantic chances.
