A client is on trial for a violent offense and the defense claims the client was legally insane at the time of the act. According to the M'Naghten Rule, which criterion must be met for the insanity defense to be valid?
The client was unable to distinguish right from wrong due to a mental disorder at the time of the crime.
The client had a documented history of mental illness prior to the crime.
The client was compelled by uncontrollable impulses to commit the act.
The client was unaware of the consequences of their actions due to intoxication.
The Correct Answer is A
Choice A reason: The M’Naghten Rule requires proof that, due to mental illness, the person did not understand the nature of the act or could not distinguish right from wrong at the time of the offense. This is the key standard used in many jurisdictions for insanity defenses.
Choice B reason: Having a history of mental illness alone is not sufficient; the rule focuses on the client’s mental state during the offense, not prior diagnoses.
Choice C reason: Being driven by uncontrollable impulses is not part of the M’Naghten criteria. This falls more under the “irresistible impulse” test, which is separate.
Choice D reason: Intoxication, even if it impairs judgment, does not qualify under the M’Naghten Rule. Voluntary substance use generally excludes insanity defenses.

Correct Answer is ["B","D","E"]
Explanation
Choice A reason: Sharing personal loss shifts the focus away from the patient, which is not therapeutic. Self-disclosure in this way can hinder supportive communication.
Choice B reason: Suggesting a grief support group acknowledges the patient’s feelings while offering a constructive coping resource. It validates distress and provides support.
Choice C reason: Leaving the patient when they are emotionally vulnerable conveys abandonment instead of support, which is not therapeutic.
Choice D reason: Normalizing grief as a process that takes time offers reassurance without minimizing the client’s emotions. It helps the patient understand that healing is gradual.
Choice E reason: Encouraging the patient to share coping strategies promotes expression of feelings and helps the nurse assess adaptive versus maladaptive coping mechanisms.
Correct Answer is D
Explanation
Choice A reason: Long-term memory and emotional responses are primarily associated with the limbic system, particularly the hippocampus and amygdala, not the hypothalamus.
Choice B reason: Voluntary muscle control and reflexes are coordinated by the motor cortex and spinal cord, not the hypothalamus.
Choice C reason: Processing sensory input and initiating motor responses are functions of the thalamus and cerebral cortex. The hypothalamus is not directly responsible for this role.
Choice D reason: The hypothalamus regulates homeostasis, including body temperature, thirst, fluid balance, circadian rhythms, and hormone release. A tumor compressing this area explains the patient’s symptoms.
