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 B
Explanation
The nurse would need to report an oral temperature of 101 F to the provider immediately. This could be a sign of neuroleptic malignant syndrome (NMS), a rare but potentially life-threatening reaction to antipsychotic medications such as haloperidol ¹. NMS can cause high fever, muscle rigidity, and changes in mental status ¹.
Option A is incorrect because dry mouth is a common side effect of haloperidol and would not need to be reported to the provider immediately ².
Option C is incorrect because drowsiness is a common side effect of haloperidol and would not need to be reported to the provider immediately ⁴.
Option D is incorrect because a blood pressure of 104/72 mmHg is within the normal range and would not need to be reported to the provider immediately.
Correct Answer is A
Explanation
In pharmacodynamics, receptors play a crucial role in mediating the effects of medications ¹. Medications must bind with receptors to mimic or block the actions of the body's own regulatory molecules ¹. This binding can activate or inhibit the receptor, leading to a biological response ¹.
Option B is incorrect because activation of the receptor by the medication does not necessarily cause the cell to develop a new function.
Option C is incorrect because receptors do not start the process of metabolism of the medication by the liver.
Option D is incorrect because binding a medication to a receptor does not necessarily make the medication more selective to that type of receptor.
