Question 1 of 5
A patient has been diagnosed with memory dysfunction associated with Alzheimer?s disease. The nurse determines that damage to the patient?s brain includes deterioration of temporal lobe structures and the nerves of which of the following?
Correct Answer: D
Rationale: Alzheimer?s disease involves memory dysfunction due to deterioration of the hippocampus (part of the limbic system in the temporal lobe) and other temporal lobe structures. The basal ganglia regulate movement, the limbic system broadly affects emotions, and the frontal lobe handles executive functions.
Question 2 of 5
The nurse is caring for a hospitalized patient who has a disorder of the hypothalamus. When developing the patient?s plan of care, in which of the following areas would the nurse anticipate a problem?
Correct Answer: A
Rationale: The hypothalamus regulates functions like sleep, hunger, and body temperature. A disorder may disrupt sleep patterns. Constipation is less directly related, speech involves cortical areas like Broca?s, and motor activity is primarily controlled by the basal ganglia and motor cortex.
Question 3 of 5
A patient who is scheduled to undergo a sleep deprivation electroencephalogram (EEG) in the morning is experiencing moderate anxiety about the procedure. Based on an understanding of this test, which of the following would the nurse avoid?
Correct Answer: B
Rationale: A sleep deprivation EEG requires the patient to stay awake to provoke brain activity for diagnosis. Administering a benzodiazepine, which promotes sedation, would counteract this purpose. Explaining the procedure, taking a history, and offering a noncaffeinated beverage are appropriate and support the test?s goals.
Question 4 of 5
A nursing instructor asks a student to explain the influence of chronobiology on depression. Which of the following would the student include when responding?
Correct Answer: D
Rationale: Chronobiology studies biological rhythms, such as circadian rhythms, which influence mood disorders like depression. Internal (e.g., hormonal changes) and external (e.g., light exposure) triggers can disrupt these rhythms, contributing to depressive symptoms. The other options relate to genetics, brain connectivity, or sensory function, not chronobiology.
Question 5 of 5
When describing the various neurotransmitters, which of the following would the nurse identify as the primary cholinergic neurotransmitter?
Correct Answer: B
Rationale: Acetylcholine is the primary cholinergic neurotransmitter, acting in the parasympathetic nervous system and at neuromuscular junctions. Dopamine, norepinephrine, and serotonin are monoamine neurotransmitters, not cholinergic.
