Final answer:
Nurses should be aware that hospital-provided malpractice insurance usually only covers on-duty activities, might offer limited coverage, and can potentially be terminated at any time. The correct options are 1, 2, and 4.
Step-by-step explanation:
A nurse considering purchasing malpractice insurance should be aware that malpractice insurance provided by the hospital generally only offers protection while on duty. This means that any professional activities conducted outside of hospital hours or contracted duties may not be covered by the hospital's insurance policy.
Additionally, the coverage provided by hospitals can often be limited in the amount of coverage, which may not be sufficient in all malpractice cases. There's also the potential that the hospital's malpractice insurance policy can be terminated at any time which could leave nursing staff unprotected. Lastly, while not typically a problem, hospital-provided insurance policies can sometimes have renewal issues, although this is less common than the other factors mentioned.
