Psychotropic Medications Medcomm Quiz Questions
Question 1 of 5
The nurse knows that determining whether a person is oriented to his or her surroundings will test the functioning of which structure(s)?
Correct Answer: A
Rationale: The correct answer is A: Cerebrum. The cerebrum is responsible for higher brain functions, including cognition, perception, and awareness of surroundings. Orientation to surroundings involves awareness of time, place, and person, which are cognitive functions controlled by the cerebrum. The cerebellum (B) controls coordination and balance, not orientation. The CNS (C) includes the brain and spinal cord, but specifically, the cerebrum is responsible for orientation. The medulla oblongata (D) regulates vital functions like breathing and heart rate, not orientation. Thus, choice A is correct as it directly relates to cognitive functions necessary for orientation.
Question 2 of 5
A nurse administers a medication that potentiates the action of gamma-aminobutyric acid (GABA). Which finding would be expected?
Correct Answer: A
Rationale: The correct answer is A: Reduced anxiety. GABA is an inhibitory neurotransmitter that helps calm the brain, reducing anxiety. By potentiating GABA's action, the medication would enhance its calming effect, leading to reduced anxiety. Improved memory (B), more organized thinking (C), and fewer sensory perceptual alterations (D) are unlikely because GABA primarily influences anxiety and relaxation, not memory, cognitive organization, or sensory perception.
Question 3 of 5
A patient is hospitalized for major depression. Of the medications listed, a nurse can expect to provide the patient with teaching about:
Correct Answer: B
Rationale: The correct answer is B, fluoxetine (Prozac), because it is an antidepressant commonly used to treat major depression. The nurse should provide teaching about its dosage, side effects, and potential interactions. Chlordiazepoxide (A) is a benzodiazepine used for anxiety, not depression. Clozapine (C) is an antipsychotic used for schizophrenia, not depression. Tacrine (D) is used for Alzheimer's disease, not depression. Therefore, options A, C, and D are incorrect for teaching a patient hospitalized for major depression.
Question 4 of 5
A patient’s spouse, who is a chemist, asks a nurse how serotonin reuptake inhibitors (SSRIs) lift depression. The nurse should explain that SSRIs:
Correct Answer: B
Rationale: The correct answer is B because SSRIs work by blocking the reuptake of serotonin at the presynaptic neuron. This leads to more serotonin being available in the synaptic gap, which enhances neurotransmission and helps alleviate depression symptoms. Choices A, C, and D are incorrect because SSRIs do not destroy neurotransmitters, increase production of acetylcholine and dopamine, or block muscarinic and alpha1-norepinephrine receptors.
Question 5 of 5
A patient shows a nurse this advertisement: “Our product is a scientific breakthrough helpful for depression, anxiety, and sleeplessness. Made from an ancient formula, it stimulates circulation and excretes toxins. Satisfaction guaranteed or your money back.” Select the nurse’s best response
Correct Answer: C
Rationale: The correct response is C: "Let’s do some additional investigation of that product." This is the best response because the advertisement makes bold claims about the product without providing any scientific evidence or approval from healthcare authorities. By suggesting further investigation, the nurse maintains a professional and cautious approach towards the product's claims. It shows a willingness to gather more information before making any recommendations. Option A is incorrect because it makes a blanket statement about over-the-counter products without addressing the specific product in question. Option B is too strict and may not be necessary if the product is safe and effective. Option D assumes the patient is self-medicating without exploring their intentions or knowledge about the product.
