Question 3 of 5
A 54-year-old woman suffering from initial insomnia was prescribed a hypnotic drug that increases the activity of a major neurotransmitter system in the brain. Which neurotransmitter system was most likely involved in the therapeutic action of that drug?
Correct Answer: D
Rationale: The correct answer is D: GABAergic. GABA is the major inhibitory neurotransmitter in the brain, and drugs that enhance GABA activity, such as benzodiazepines, are commonly used as hypnotics to treat insomnia. By increasing GABAergic activity, the drug helps to promote relaxation and induce sleep. Choices A, B, and C are incorrect because they do not directly relate to the therapeutic action of hypnotic drugs for insomnia. Cholinergic, noradrenergic, and glutamatergic systems are not primarily involved in promoting sleep and reducing insomnia symptoms.
Question 4 of 5
Which of the following neurotransmitters has been most consistently implicated in the patient's disorder?
Correct Answer: A
Rationale: The correct answer is A: Acetylcholine. Acetylcholine is most consistently implicated in disorders like Alzheimer's disease due to its role in memory and cognitive functions. Dysfunction in acetylcholine signaling is a hallmark of this disorder. Norepinephrine is primarily involved in the stress response, GABA in regulating anxiety, and serotonin in mood regulation. However, acetylcholine's direct association with cognitive impairment makes it the most likely neurotransmitter involved in the patient's disorder.
Question 5 of 5
Which of the following symptoms did the patient most likely experience upon recovery from sedation?
Correct Answer: C
Rationale: The correct answer is C: Anterograde amnesia. Upon recovery from sedation, the patient most likely experienced anterograde amnesia, which is the inability to form new memories after sedation. This occurs due to the effects of sedative medications on the brain's ability to encode and store new information temporarily. This symptom is commonly associated with sedative medications and is a typical outcome of sedation procedures. A: Nausea and vomiting are common side effects of sedation but are more likely to occur during or shortly after sedation, rather than upon recovery. B: Increased respiratory rate may occur during sedation due to the effects of sedative medications on the respiratory system, but it is not a typical symptom upon recovery. D: Limb muscle spasms are not typically associated with recovery from sedation and are more likely to be a sign of a different medical condition or side effect of a different medication.
