Question 1
Multiple Choice
When describing the action of cholinesterase inhibitors to a class of nursing students, the instructor would include which of the following about their action?
Correct!
Incorrect
The correct answer is: B,C
Rationale
Cholinesterase inhibitors inhibit the breakdown of acetylcholine. This action increases the availability of acetylcholine at synapses, enhancing neurotransmission, which is critical for improving symptoms in conditions like Alzheimer's disease and myasthenia gravis.
A: The drugs decrease the level of acetylcholine in the CNS. This statement contradicts the action of cholinesterase inhibitors, which actually aim to increase acetylcholine levels for better neural communication.
C: The drugs slow neural destruction. While cholinesterase inhibitors may have protective effects, their primary function is not directly related to slowing overall neural destruction but rather enhancing acetylcholine action.
D: They stop neural breakdown. Cholinesterase inhibitors do not prevent neural breakdown entirely; their role is to enhance neurotransmission by preserving acetylcholine levels rather than halting neural degeneration processes.
E: The drugs increase excitatory neurotransmitters in the CNS. Cholinesterase inhibitors specifically target acetylcholine rather than broadly increasing excitatory neurotransmitters, thus focusing on a specific neurotransmission pathway.

B: Increased risk of NSAID toxicity. While donepezil can affect gastrointestinal function, it does not directly influence the metabolism or clearance of NSAIDs, maintaining their safety profile in therapeutic dosages.
D: Decrease GI absorption of the donepezil. There’s no evidence suggesting NSAIDs alter the absorption dynamics of donepezil, as their pharmacokinetic profiles operate independently in the gastrointestinal tract.
Question 21
Regular
The caregiver of a client diagnosed with AD asks the nurse about the prescribed therapy with rivastigmune and about how the drug works. The nurse would integrate knowledge of which action in the response to the caregiver?
Correct!
Incorrect
The correct answer is: A
Rationale
Increases the level of acetylcholine in the CNS.
Rivastigmine works by inhibiting the enzyme acetylcholinesterase, leading to increased levels of acetylcholine in the central nervous system. This enhancement aids cognitive function and helps manage symptoms associated with Alzheimer’s disease, thereby providing therapeutic benefits to the client.
B: Decreases the level of neurotoxins in the brain. Rivastigmine does not specifically target neurotoxins; its primary action focuses on enhancing acetylcholine levels, which is crucial for cognitive processes.
C: Increases the level of cholinesterase in the blood. The drug’s mechanism involves inhibiting cholinesterase, not increasing it, to ensure elevated acetylcholine levels for improved cognitive function.
D: Increases the level of adenosine triphosphate in the blood. Rivastigmine does not influence ATP levels; its primary role is to impact acetylcholine levels, which is vital for managing Alzheimer’s symptoms.

Question 22
Regular
A caregiver of a client diagnosed with AD asks the nurse about the cholinesterase inhibitor galantamine prescribed for the client. Which response by the nurse would be most appropriate?
Correct!
Incorrect
The correct answer is: C
Rationale
Cholinesterase inhibitors like galantamine are designed to slow the progression of Alzheimer's disease by enhancing communication between nerve cells. This helps manage symptoms related to memory and cognitive function over time.
A: The drug will help to cure the memory problems the client is experiencing. Cholinesterase inhibitors do not cure Alzheimer's disease; they merely alleviate symptoms without reversing underlying damage.
B: Once the symptoms improve, the drug will most likely be stopped. These medications typically require ongoing administration to maintain their benefits, as they do not lead to permanent improvements.
D: This drug is primarily given to control the delirium the client is experiencing. Galantamine is specifically focused on cognitive decline in Alzheimer's, not delirium, which is a different condition requiring alternative management.

Question 23
Regular
After teaching a group of nursing students about cholinesterase inhibitors, the instructor determines that additional teaching is needed when the students identify which drug as an example?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Memantine. Memantine is not classified as a cholinesterase inhibitor; instead, it functions as an NMDA receptor antagonist. This distinction demonstrates the need for further clarification among the students regarding drug classifications.
A: Rivastigmine. Rivastigmine is a well-known cholinesterase inhibitor used in treating Alzheimer's disease, making it a valid example of this class of medications.
B: Donepezil. Donepezil is another established cholinesterase inhibitor that effectively increases acetylcholine levels in the brain, confirming its relevance to the topic being taught.
D: Galantamine. Galantamine also acts as a cholinesterase inhibitor, enhancing cognitive function by preventing the breakdown of acetylcholine, thus fitting the category accurately.

Question 24
Regular
After teaching the caregiver of a client prescribed transdermal rivastigmine, the nurse determines that the teaching was successful when the caregiver states which of the following?
Correct!
Incorrect
The correct answer is: B
Rationale
The patch should be placed on a hairless area. Applying the patch to a hairless site helps ensure optimal absorption of rivastigmine and minimizes skin irritation, enhancing the treatment's effectiveness and patient comfort.
A: I'll apply a new patch every other day. Patches must be replaced every seven days to maintain consistent medication levels and prevent overdosing, highlighting a misunderstanding of the application schedule.
C: I'll make sure to put the patch where he can see it. Visibility does not contribute to the medication's efficacy; the focus should be on proper placement for absorption, not visibility.
D: I can use the same spot once or twice a week. Rotating the application site is essential to prevent skin irritation and ensure effective drug delivery, making this statement misleading.

Question 25
Regular
The daughter of a client with AD who is receiving cholinesterase inhibitor therapy tells the nurse that her father has been getting more and more clumsy lately, saying, 'He's almost fallen several times and he often gets out of bed at night. That's when I'm most concerned that he will fall.' The daughter reports that his appetite is fair and that he takes his medication as prescribed. When developing the client's plan of care, the nurse would identify which nursing diagnosis as the priority?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Risk for Injury This diagnosis is prioritized due to the daughter's report of her father becoming increasingly clumsy and at risk of falling, especially at night when he gets out of bed. The potential for injury necessitates immediate intervention to ensure his safety and prevent accidents, making this the most critical concern in his care plan.
A: Imbalanced Nutrition: Less Than Body Requirements This option does not address the immediate safety concerns related to the client's clumsiness and risk of falling. The client's appetite is reported as fair, indicating that nutritional needs may not be compromised.
C: Ineffective Self Health Management This diagnosis does not reflect the primary issue of physical safety highlighted by the daughter's observations. The focus is on the risk of injury rather than self-management abilities.
D: Deficient Knowledge: drug therapy While medication adherence is confirmed, this option overlooks the more pressing concern of the client's physical stability. The situation described points to a clear risk for injury rather than knowledge deficits.

Question 26
Regular
A group of nursing students are reviewing the stages of AD. They demonstrate understanding of the information when they identify which of the following as characteristic of preclinical AD?
Correct!
Incorrect
The correct answer is: D
Rationale
D: There are no cognitive changes noted. Preclinical Alzheimer's Disease (AD) is characterized by an absence of noticeable cognitive impairment, making this stage distinct as individuals may still function normally, despite underlying pathological changes.
A: Client's changes in thinking are readily evident to family members. This description pertains to more advanced stages of AD, where cognitive decline becomes apparent to those close to the individual.
B: The client may exhibit moderate levels of anxiety. Anxiety can occur in various conditions but is not a defining characteristic of preclinical AD, which lacks observable cognitive symptoms.
C: The ability to function is significantly limited. Significant functional limitations indicate progression to later stages of AD, contrasting with preclinical AD, where individuals maintain their daily functions despite underlying issues.

Question 27
Regular
A nurse is reviewing the action of memantine. The nurse understands that this drug addresses which of the following?
Correct!
Incorrect
The correct answer is: B
Rationale
Memantine addresses glutamate. This drug functions by modulating the activity of glutamate at the NMDA receptor, which is crucial for learning and memory, particularly in conditions like Alzheimer's disease.
A: Acetylcholine Modulating acetylcholine does not align with memantine's mechanism, as this neurotransmitter is primarily associated with different pathways and is not the primary focus of memantine’s action.
C: Serotonin Memantine does not engage with serotonin pathways, which are primarily involved in mood regulation, thus making it irrelevant to the drug's intended therapeutic effects.
D: Dopamine Dopamine's role in reward and motor control systems does not connect with memantine’s function, which targets glutamate receptors rather than influencing dopaminergic signaling in the brain.
