Final answer:
The nurse's statement that a misdemeanor results in a fine shows an understanding of legal actions by correctly identifying misdemeanors as less serious crimes compared to felonies, which carry heavier penalties.
Step-by-step explanation:
Understanding legal actions requires distinguishing between criminal law and civil law, as well as the different levels of crimes, like felonies and misdemeanors. Statement (a) "A misdemeanor is a less serious crime resulting in a fine." indicates an understanding of basic legal definitions. A misdemeanor is indeed a less serious crime than a felony and generally results in lighter penalties like fines or short-term incarceration. Conversely, a felony is a serious offense that can lead to long-term imprisonment or even more severe consequences. Civil actions, stated in option (c), typically involve disputes between individuals or organizations and usually do not result in prison time as their focus is more on restitution and resolving non-criminal conflicts. Therefore, the nurse's understanding of legal actions is demonstrated by the knowledge that a misdemeanor is a less serious crime which can result in a fine.
