The older adult client diagnosed with Parkinson's disease (PD) has been prescribed the combination medication carbidopa/levodopa. Which data indicates the medication is effective?
The client is able to walk upright without stumbling.
The client eats 30% to 40% of meals within 1 hour.
The client does not display emotions when discussing the illness.
The client has cogwheel motion when swinging the arms.
The Correct Answer is A
Carbidopa/levodopa is a medication used to treat the symptoms of Parkinson's disease, including tremors, stiffness, and difficulty with movement. If the medication is effective, the client should show improvement in their ability to move and perform daily activities. In this case, the client being able to walk upright without stumbling indicates that the medication is effective.
Option B is incorrect because eating 30% to 40% of meals within 1 hour is not related to the effectiveness of carbidopa/levodopa.
Option C is incorrect because displaying emotions when discussing the illness is not related to the effectiveness of carbidopa/levodopa.
Option D is incorrect because cogwheel motion when swinging the arms is a symptom of Parkinson's disease and would indicate that the medication is not effective.

Correct Answer is A
Explanation
Donepezil is a medication used to treat Alzheimer's dementia. Its main mechanism of action is the inhibition of the acetylcholinesterase enzyme in the brain ¹. This increases the availability of acetylcholine at cholinergic synapses ⁵, which can improve cognition and function in clients with Alzheimer's dementia ¹.
Option B is incorrect because donepezil does not decrease acetylcholine in the periphery to increase movement.
Option C is incorrect because donepezil does not delay the transmission of acetylcholine at the neuronal junction.
Option D is incorrect because donepezil does not bind dopamine at neuron receptor sites to increase ability.
Correct Answer is D
Explanation
Intravenous (IV) administration of medication involves injecting the medication directly into a vein. This route of administration has the most rapid onset of action because the medication is delivered directly into the bloodstream and can be quickly distributed throughout the body.
Options a, b, and c are not correct because they do not have as rapid an onset of action as intravenous administration. Sublingual administration involves placing the medication under the tongue, where it is absorbed into the bloodstream through the mucous membranes. Intradermal administration involves injecting the medication into the top layer of the skin. Subcutaneous administration involves injecting the medication into the fat tissue just under the skin. While these routes can be effective for delivering medication, they do not have as rapid an onset of action as intravenous administration.
