A nurse in an outpatient mental health facility is preparing to administer phenelzine to a client who has been taking this medication for several years. The client reports eating a grilled cheese sandwich and a banana for lunch and is feeling dizzy. Which of the following vital signs should the nurse assess first?

Choice A reason: While discussing the client's diagnosis with their family could be part of the care process, it does not address the client's immediate concern about the quality of care they are receiving. This response does not validate the client's feelings or provide an opportunity for them to elaborate on their concerns.

Choice B reason: Telling the client that their feelings are part of anticipatory grieving may be true, but it can come across as dismissive and does not offer support for the specific issue the client has raised about the quality of care.

Choice C reason: Assuring the client that the nurses are trying to provide good care does not acknowledge the client's perception of inadequate care. It's important to validate the client's feelings and understand their perspective before offering reassurances.

Choice D reason: Asking the client to elaborate on their concerns shows empathy and a willingness to listen. It allows the nurse to gather more information about the client's experience and identify specific areas that may need improvement in the care provided.

Choice A reason: Witnessing an informed consent is a legal process that typically requires a licensed nurse or healthcare provider to ensure that the client fully understands the procedure and its risks. It is not appropriate to delegate this task to assistive personnel.

Choice B reason: Explaining the benefits of light therapy involves providing health education, which should be done by a licensed nurse or healthcare provider who has the necessary knowledge and training to ensure accurate information is conveyed.

Choice C reason: Discussing the adverse effects of medications is part of medication education and should be conducted by a licensed nurse or healthcare provider. Assistive personnel are not trained to provide this level of detailed medical information.

Choice D reason: Participating in solitary activities does not require clinical judgment and can be safely delegated to assistive personnel. This task involves engaging the client in activities that can help manage their mania and provide a therapeutic environment.
