The answer to the question above would be "NURSE'S". What makes this incorrect is that, it is not in the PLURAL possessive form but rather only the singular possessive form. The singular form is NURSE, and the plural form is NURSES. Therefore, the apostrophe should be after the letter "s" just like the "Doctors'" and "technicians'". Hope this helps.
Well if that is a true or false question, I would say true - thinking back on my experiences with my parents, who did not like us to contradict their opinions.
