Question 1 of 5
When the nurse explains the pathophysiology of myasthenia gravis to a patient, which is the best explanation?
Correct Answer: B
Rationale: The correct answer is B because myasthenia gravis is an autoimmune disorder where the body attacks its own acetylcholine receptors, leading to decreased communication between nerves and muscles, causing muscle weakness. Choice A is incorrect because it describes the pathophysiology of Alzheimer's disease, not myasthenia gravis. Choice C is incorrect as it describes multiple sclerosis, not myasthenia gravis. Choice D is incorrect as it describes Parkinson's disease, not myasthenia gravis. Remember, in myasthenia gravis, the issue is a decreased amount of acetylcholine to cholinergic receptors, not an imbalance of neurotransmitters like dopamine and acetylcholine.
Question 2 of 5
The nurse anticipates that the health care provider will prescribe which medication to treat a patient with relapsing remitting multiple sclerosis?
Correct Answer: D
Rationale: The correct answer is D: Glatiramer acetate. This medication is commonly used to treat relapsing-remitting multiple sclerosis by reducing the frequency of relapses. It works by modulating the immune system to prevent inflammation and damage to the nervous system. Ambenonium (A) and Pyridostigmine (B) are used to treat myasthenia gravis, a neuromuscular disorder, not multiple sclerosis. Mitoxantrone (C) is used for aggressive forms of multiple sclerosis, not for relapsing-remitting MS. In summary, Glatiramer acetate is the correct choice for treating relapsing-remitting multiple sclerosis due to its mechanism of action and proven efficacy.
Question 3 of 5
The nurse is providing medication instructions to a patient with acute muscle spasms who has been prescribed cyclobenzaprine. Which statement indicates to the nurse that the patient understands the instructions?
Correct Answer: A
Rationale: Correct Answer: A Rationale: 1. Cyclobenzaprine can cause drowsiness, so it is recommended to take it at bedtime. 2. Taking it with a glass of milk can help minimize stomach upset. 3. The patient's understanding is demonstrated by planning to take it with milk for optimal effect and compliance. Summary: B: Incorrect. While cyclobenzaprine can be taken at bedtime, the patient's understanding is not demonstrated by this statement. C: Incorrect. Drinking alcohol, even in moderation, can increase drowsiness and impair cognitive function. D: Incorrect. Grapefruit juice can interact with cyclobenzaprine, leading to potentially harmful side effects.
Question 4 of 5
A patient is beginning to take cyclobenzaprine for treatment of acute back spasms. Which interventions will the nurse include in the care of this patient? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: Inform the patient not to abruptly stop taking the muscle relaxant. Abruptly stopping cyclobenzaprine can lead to withdrawal symptoms. Gradual tapering is necessary to prevent adverse effects. Choice A is incorrect as cyclobenzaprine can be taken with or without food. Choice C is incorrect as alcohol should be avoided while taking muscle relaxants. Choice D is irrelevant to the question and not related to the care of a patient taking cyclobenzaprine.
Question 5 of 5
A 3-year-old boy was brought to the emergency department with dilated pupils, dry mouth, red and dry skin, and a body temperature of 103.4°F. Vital signs were blood pressure 90/50 mm Hg, pulse 122 bpm, respirations 24/min. The central and peripheral symptoms of this patient were most likely mediated by the blockade of which of the following receptors?
Correct Answer: C
