According to the Bureau of Labor Statistics, the LPN occupation is expected to grow 14 percent between 2006 and 2016. Because the duties of LPN professionals are so comprehensive, licensed practical nurses can be employed in a wide variety of settings. LPNs employed in a hospital may find themselves working in a patient unit such as obstetrics or psychiatry. Private physician practices employ licensed practical nurses to take patient vital signs, help collect lab specimens, and assist physicians with patient examinations. Companies that perform employment physicals or employee drug testing also employee LPNs. In this setting, the LPN may be responsible for collecting samples, preparing patients for exams, and assisting physicians with employment physicals.
