Final answer:
LPNs generally focus on routine tasks under RN supervision. Teaching medication administration and admitting patients from post-anesthesia care are outside their scope, and administering IV medications like lorazepam may also be restricted.
Step-by-step explanation:
The tasks that cannot be delegated to a licensed practical nurse (LPN) involve complex assessments, patient education, and high-level clinical decision-making. Under the direct supervision of a registered nurse, an LPN's focus is generally on specific routine tasks.
- Administering PO morphine is within the scope of an LPN, provided they have the appropriate certification for medication administration.
- Teaching a new patient proper nitroglycerin administration is typically outside the LPN's scope and requires the expertise of a registered nurse or advanced healthcare provider to ensure comprehensive patient education and understanding of the medication.
- LPNs usually do not admit patients from the post-anesthesia care unit because this involves complex assessments that are the responsibility of the RN or an advanced provider.
- Administering I.V. Lorazepam could vary by institution policy, but administration of certain IV medications, especially high-risk ones like lorazepam, often falls under the RN's scope.
- Dressing changes of a patient, post-op day 5, is within the LPN's capabilities, and they can generally perform this task.
- Performing a urinary catheterization can also be part of the LPN's role unless specified otherwise by the state's scope of practice or facility policy.
In summary, teaching a new patient proper nitroglycerin administration and admitting a patient from the post-anesthesia care unit are tasks that cannot be delegated to an LPN, and administration of IV medications such as lorazepam might also be restricted, depending on the institution's regulations and state laws. Routine tasks like dressing changes and catheterizations are generally within the LPN's scope under supervision.
