Nursing is one of the noble professions that deal with the care for human life. Their duty is vital in medical history because without them, the doctors cannot function properly. Nurses also are in charge of keeping proper medical records.
In the hospital for example, they make the necessary tools needed during surgery handy, more like a ball boy in a football. They also walk round the wards routinely and at stipulated times to administer injections and drugs either as tablets or infusions to patients where needed.
