Fidelity in nursing practice primarily refers to:

Choice A rationale
Following the order as prescribed without clarification can lead to errors if the order is unclear or incomplete.
Choice B rationale
Administering the medication at a later time without clarification can also lead to errors and may delay necessary treatment.
Choice C rationale
Disregarding the order and seeking approval from another physician is not appropriate. The nurse should seek clarification from the ordering physician.
Choice D rationale
Asking the physician to clarify the dosage and route ensures that the order is accurate and complete, reducing the risk of medication errors.

Choice A rationale
Calculating intake and output for the unit is a task that can be delegated to an LVN or UAP. It does not require the advanced clinical judgment and skills of an RN.
Choice B rationale
Inserting an NGT (nasogastric tube) for a client who is unable to eat is a task that can be performed by an LVN under the supervision of an RN. While it requires skill, it does not necessarily require the advanced clinical judgment of an RN.
Choice C rationale
Reinforcing teaching with a patient who is learning to walk with a quad cane can be done by an LVN or UAP. This task involves providing support and encouragement, but it does not require the advanced clinical judgment of an RN.
Choice D rationale
An unstable client complaining of feeling faint requires the advanced clinical judgment and skills of an RN. The RN is best equipped to assess the client’s condition, identify potential causes of instability, and implement appropriate interventions to stabilize the client.
