A nurse is providing an in-service to the unit about medications that are classified as antihistamines.
Which of the following medications are considered an antihistamine? (Select All That Apply).

Choice A rationale

Lisinopril is an antihypertensive medication and is not classified as a controlled substance.

Choice B rationale

Naloxone (Narcan) is an opioid antagonist used to reverse opioid overdoses and is not a controlled substance.

Choice C rationale

Tetracycline is an antibiotic and not classified as a controlled substance.

Choice D rationale

Morphine is an opioid analgesic used for pain management and is classified as a controlled substance due to its potential for abuse and dependence.

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.
