Correct Answer is ["A","B","C"]
Explanation
Choice A rationale
Determining the dosage is a critical responsibility of the nurse to ensure the patient receives the correct amount of medication, which is essential for therapeutic effectiveness and patient safety. This practice aligns with legal guidelines to avoid underdosing or overdosing, which could lead to adverse outcomes.
Choice B rationale
Teaching the client about the medication is part of the nurse's duty to promote patient understanding, compliance, and informed consent. Educating clients about their medications, including potential side effects and proper administration, helps in preventing medication errors and promoting safe, effective treatment.
Choice C rationale
Monitoring for adverse effects is crucial to ensure patient safety and the efficacy of the medication. Nurses must observe and report any negative reactions to the medication to adjust treatment promptly, which is part of their legal and ethical responsibilities.
Choice D rationale
Determining the client's insurance status is generally not considered part of a nurse's duties related to medication administration under legal practice guidelines. This task is more aligned with administrative or billing departments rather than clinical nursing responsibilities.
