To evaluate the effectiveness of nitroglycerin 0.4 mg SL administered to a client diagnosed with angina pectoris, the nurse should:

Choice A Reason
A client with paranoid personality disorder is typically not described as superficially charming. This description is more often associated with other personality disorders, such as antisocial personality disorder, where individuals may use charm to manipulate others for personal gain.

Choice B Reason
Being friendly and open is generally not characteristic of paranoid personality disorder. Individuals with this disorder are often wary of others and may be perceived as cold or distant due to their mistrust.

Choice C Reason
While intensity and impulsivity can be seen in various personality disorders, they are not the defining features of paranoid personality disorder. These traits are more commonly associated with borderline personality disorder.

Choice D Reason
Guarded and suspicious are hallmark descriptors for someone with paranoid personality disorder. Individuals with this condition are often very distrustful of others, suspecting that others have ulterior motives or are out to harm them. They may be preoccupied with doubts about the loyalty or trustworthiness of friends or associates.

Choice A Reason
Intervening when a client attempts self-injury may be necessary to ensure the client's immediate safety. However, this action does not primarily implement the ethical principle of autonomy. Autonomy involves respecting the client's right to make their own decisions, including the right to refuse treatment. In cases of self-harm, the nurse must balance the ethical principles of autonomy and nonmaleficence (the duty to do no harm)

Choice B Reason
Suggesting restrictions for clients who were fighting might be a measure to maintain safety within the unit. However, this suggestion does not uphold the principle of autonomy, as it involves limiting the clients' freedom and choices. The ethical principle of autonomy emphasizes the clients' right to make independent choices and to control their own actions.

Choice C Reason
Staying with a client who is experiencing a high level of anxiety is a supportive action that can be therapeutic. While it demonstrates care and may provide comfort, it does not directly implement the principle of autonomy. Autonomy is about the capacity to make informed and voluntary decisions, and while support is important, it does not equate to enabling decision-making.

Choice D Reason
Exploring alternative solutions with a client and allowing them to choose an option embodies the ethical principle of autonomy. This approach respects the client's right to be involved in their own care and to make decisions based on their values and beliefs. It empowers the client to have control over their treatment and respects their capacity for self-determination.

In psychiatric nursing, respecting autonomy means acknowledging the client's right to make choices about their care and treatment. It involves providing all necessary information and supporting the client in making informed decisions. By exploring options and allowing the client to choose, the nurse facilitates autonomy and supports the client's right to direct their own care.
