Which of the following abbreviations represents "Licensed Practical Nurse"?

The abbreviation that represents "Licensed Practical Nurse" is LPN. This designation is widely recognized within the healthcare field and refers to a nurse who has completed the necessary training and licensing requirements to provide basic medical care under the supervision of registered nurses and physicians. LPNs typically hold a diploma or certificate from an accredited nursing program and are trained to perform tasks such as monitoring patient health, administering medications, and assisting with daily living activities.

In the context of the other choices, LP does not specifically denote any nursing license and is not commonly used in the healthcare profession. LVN, or Licensed Vocational Nurse, is equivalent to an LPN and is used in specific regions, particularly in California and Texas, but it is not the standard abbreviation. RN stands for Registered Nurse, which is a higher level of nursing qualification requiring more extensive education and training than that of an LPN. Thus, LPN stands as the correct and universally accepted abbreviation for Licensed Practical Nurse.
