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.

A half-life is the time it takes for the concentration of a drug in the body to decrease by half. In this case, the medication has an 8-hour half-life, so after 8 hours, the concentration of the medication in the client's body would be reduced to 400mg (half of the initial dose of 800mg). After another 8 hours (16 hours total), the concentration would be reduced to 200mg. After another 8 hours (24 hours total), the concentration would be reduced to 100mg.
