Question 3 of 5
A patient™s history shows drinking 4 to 6 L of fluid and eating more than 6,000 calories per day. Which part of the central nervous system is most likely dysfunctional for this patient?
Correct Answer: D
Rationale: The correct answer is D: Hypothalamus. The hypothalamus plays a crucial role in regulating hunger, thirst, and satiety. In this case, the patient's excessive fluid intake and caloric consumption suggest dysfunction in the hypothalamus, leading to disrupted signals related to hunger and thirst regulation. The amygdala (A) is involved in emotional processing, the parietal lobe (B) in sensory information processing, and the hippocampus (C) in memory consolidation, making them less likely to be the main cause of the symptoms described.
Question 4 of 5
A patient has disorganized thinking associated with schizophrenia. Neuroimaging would likely show dysfunction in which part of the brain?
Correct Answer: B
Rationale: The correct answer is B: Frontal lobe. In schizophrenia, disorganized thinking is often related to dysfunction in the frontal lobe. This area of the brain is responsible for executive functions such as planning, decision-making, and impulse control. Dysfunction in the frontal lobe can lead to difficulties in organizing thoughts and behaviors, which are characteristic symptoms of schizophrenia. The other choices (A: Hippocampus, C: Cerebellum, D: Brainstem) are not typically associated with disorganized thinking in schizophrenia. The hippocampus is more related to memory, the cerebellum to coordination and movement, and the brainstem to basic bodily functions.
Question 5 of 5
A fearful patient has an increased heart rate and blood pressure. The nurse suspects increased activity of which neurotransmitter?
Correct Answer: B
Rationale: The correct answer is B: Norepinephrine. Increased heart rate and blood pressure are characteristic of the fight-or-flight response, where the sympathetic nervous system is activated. Norepinephrine is a neurotransmitter released in response to stress and fear, leading to increased heart rate and blood pressure. GABA (A) is an inhibitory neurotransmitter that would not cause increased heart rate and blood pressure. Acetylcholine (C) is involved in parasympathetic activity, which typically decreases heart rate and blood pressure. Histamine (D) is not directly involved in the sympathetic response related to fear and stress.
