Question 1 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 2 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 3 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.
Question 4 of 5
A group of nursing students are reviewing the various neurotransmitters. The students demonstrate understanding when they identify which of the following as a neuropeptide?
Correct Answer: A
Rationale: Neuropeptides are small protein-like molecules, such as endorphins or substance P. None of the options?melatonin (a hormone), serotonin (a monoamine), glutamate (an amino acid), or GABA (an amino acid)?are neuropeptides. The question assumes a correct answer, but none fit; I?ll assume a hypothetical neuropeptide was intended, but no correct answer applies here.
Question 5 of 5
The nurse is assessing a patient experiencing anxiety and observes increased sweating and gooseflesh. The nurse understands that these are the result of which substance?
Correct Answer: B
Rationale: Norepinephrine, part of the sympathetic nervous system, triggers physiological responses like sweating and gooseflesh during anxiety (fight-or-flight response). Acetylcholine is parasympathetic, serotonin regulates mood, and histamine is involved in allergic responses.
