A nurse is assessing a client on haloperidol who has developed uncontrollable movements of the face and mouth. What condition is likely being observed?

Choice A reason: Justice refers to the fair and equitable distribution of healthcare resources and treatments. While it is a foundational ethical principle, it does not directly govern the specific dilemma of whether or not to share sensitive information regarding a client's clinical decisions with the broader multidisciplinary treatment team.

Choice B reason: Beneficence involves the duty to act in the best interest of the patient. While sharing information might lead to better care, the core tension in this scenario involves the protection of private information. Beneficence must be balanced against the client's rights to privacy and the ethical handling of their personal health data.

Choice C reason: Autonomy is the right of the patient to make their own decisions about their medical care, including the refusal of treatment. However, the nurse’s dilemma about "disclosing" that refusal to others is a question of information management and professional secrecy rather than the patient's actual right to refuse the treatment itself.

Choice D reason: Confidentiality is the duty to protect a client's private information from unauthorized disclosure. The nurse must determine if sharing the refusal with the care team falls under the umbrella of "need to know" for coordinated care or if it violates the client's privacy. Ethical practice generally supports sharing within the team to ensure safety.

Choice A reason: To calculate the correct volume, the nurse uses the standard formula: Desired dose (5 mg) divided by the dose on hand (10 mg) multiplied by the volume (1 mL). Therefore, 5 divided by 10 equals 0.5. Administering 0.5 mL provides exactly the 5 mg prescribed.

Choice B reason: Administering 2 mL would result in the patient receiving 20 mg of haloperidol. This is four times the prescribed dose and could lead to severe extrapyramidal side effects, acute dystonia, or neuroleptic malignant syndrome, representing a significant and dangerous medication administration error by the nurse.

Choice C reason: A volume of 0.25 mL would only deliver 2.5 mg of the medication. This sub-therapeutic dose would likely be ineffective in managing the patient's acute psychiatric symptoms or agitation, failing to meet the clinical objectives established by the prescribing healthcare provider's original medication order.

Choice D reason: Administering 1 mL would deliver 10 mg of haloperidol, which is double the intended 5 mg dose. Overdosing a patient on high-potency antipsychotics increases the risk of cardiac complications, such as QTc prolongation, and requires immediate reporting and monitoring for adverse neurological reactions.
