A nurse is caring for a client admitted to the emergency room exhibiting impulsive behaviors of rage and anger. Dysfunction in which brain structure contributes to this behavior?
Cerebellum
Basal Ganglia
Spinal Cord
Hypothalamus
The Correct Answer is D
A. Cerebellum: The cerebellum is primarily involved in motor coordination, balance, and muscle tone regulation. Dysfunction in the cerebellum is more likely to result in motor coordination problems rather than impulsive behaviors of rage and anger.
B. Basal Ganglia: The basal ganglia are a group of nuclei in the brain involved in motor control, learning, emotion, and cognition. Dysfunction in the basal ganglia can lead to movement disorders such as Parkinson's disease but is also associated with impulsive behaviors, including rage and anger.
C. Spinal Cord: The spinal cord primarily functions in transmitting sensory and motor signals between the brain and the rest of the body. Dysfunction in the spinal cord typically results in sensory or motor deficits rather than impulsive behaviors like rage and anger.
D. Hypothalamus: The hypothalamus plays a crucial role in regulating emotions, autonomic functions, hormone production, and homeostasis. Dysfunction in the hypothalamus can lead to disruptions in emotional regulation, including impulsive behaviors such as rage and anger.

Correct Answer is C
Explanation
A. "We have to go over these instructions before you can go. Please try to listen." - This response may come across as dismissive or confrontational, which can escalate the client's anger and hinder effective communication. It does not demonstrate empathy or understanding of the client's emotions.
B. "You should be able to regulate your feelings better by now. Why are you angry?" - This response can be perceived as judgmental and invalidating of the client's emotions. It does not promote a supportive or therapeutic environment for the client to express their feelings.
C. "I can sense you are angry. Tell me how you feel about being discharged today." - This response acknowledges the client's emotions empathetically and invites them to express their feelings openly. It demonstrates a therapeutic understanding of the client's perspective and creates an opportunity for effective communication and problem-solving.
D. "Would you rather not be discharged today?" - This response acknowledges the possibility that the client may have concerns or preferences about discharge. It opens the door for further discussion and exploration of the client's feelings and needs regarding the discharge process.
Correct Answer is ["2"]
Explanation
To calculate the number of vials needed to prepare the ordered dose of lorazepam 3 mg IV using the injectable form with a concentration of 2 mg/mL, we can use the formula:
Number of vials = Ordered dose divided by concentration per vial
Given:
Ordered dose of lorazepam: 3 mg IV
Concentration of lorazepam in each vial: 2 mg/mL
Plugging in the values:
Number of vials = 3 mg divided by 2 mg/mL
Number of vials = 1.5 vials
Since each vial contains 1 mL, and the ordered dose is 3 mg IV, the nurse will need to retrieve 1.5 mL of lorazepam. This means the nurse will need 2 vials (rounded up from 1.5 vials).
