Correct Answer is C
Explanation
Choice A reason: Allowing a client with suicidal comments to leave against medical advice is unsafe, as it risks self-harm without immediate intervention. Providing resources does not address acute suicide risk, which requires inpatient stabilization to ensure safety, making this action inappropriate in the context of expressed suicidal ideation.
Choice B reason: Contacting family to persuade the client to stay does not address immediate suicide risk. While family support may be helpful, it lacks legal authority to prevent discharge and does not ensure safety, making it less effective than initiating a commitment for a client with suicidal intent.
Choice C reason: A 302 involuntary commitment is appropriate for a client expressing suicidal ideation, indicating imminent danger to self. This legal action ensures safety through inpatient evaluation and treatment, preventing self-harm. Mental health laws prioritize protection in such cases, making this the most appropriate nursing action.
Choice D reason: Calling security to detain the client is coercive and lacks legal basis without a formal commitment process. It may escalate agitation and violate autonomy. A 302 commitment is the proper legal mechanism to ensure safety for a suicidal client, making detention by security inappropriate.
Correct Answer is C
Explanation
Choice A reason: A calm expression does not reliably indicate low anxiety, as individuals may mask emotions due to cultural norms or coping mechanisms. Nonverbal cues are subjective and context-dependent, and physiological signs like heart rate or cortisol levels are more accurate indicators of anxiety than facial expressions alone.
Choice B reason: Eye contact is not a universal measure of attentiveness, as cultural norms vary (e.g., some cultures avoid eye contact to show respect). Individual factors like anxiety or neurodiversity can also affect eye contact, making it an unreliable indicator of engagement without considering context and patient background.
Choice C reason: Nonverbal communication, such as gestures or expressions, varies widely across cultures and individuals. For example, nodding may signify agreement in one culture but acknowledgment in another. Individual personality or mental health conditions also influence nonverbal cues, making this statement accurate as it accounts for diverse interpretations.
Choice D reason: Therapeutic touch responses vary by individual and cultural preferences, and some patients may find it intrusive or distressing. Verbal interaction is often more consistent in therapeutic settings, as it allows clearer communication of intent. Touch is not universally more effective, making this statement inaccurate.
