An older patient exhibits a shuffling gait, lack of facial expression, and tremors at rest. The nurse will expect the provider to order which medication for this patient?
Carbidopa-levodopa
Donepezil
Rivastigmine
Tacrine
The Correct Answer is A
A. Carbidopa-levodopa
The symptoms described, including a shuffling gait, lack of facial expression, and tremors at rest, are characteristic of Parkinson's disease. Carbidopa-levodopa is a common medication used in the management of Parkinson's disease.
B. Donepezil
Donepezil is used in the treatment of Alzheimer's disease, a condition characterized by cognitive decline and memory impairment. It is not indicated for Parkinson's disease.
C. Rivastigmine
Rivastigmine is another medication used in the treatment of Alzheimer's disease, and it is also used in Parkinson's disease dementia. However, it is not the primary medication for the motor symptoms of Parkinson's disease.
D. Tacrine
Tacrine was once used in the treatment of Alzheimer's disease, but it is no longer commonly prescribed due to safety concerns and the availability of newer, safer medications. It is not indicated for Parkinson's disease.

Correct Answer is D
Explanation
A. Call the health care provider immediately to change the medication to oral.
Changing the medication to oral may not address the immediate issue of the burning sensation and feeling of heat at the IV site. This option focuses on changing the route of administration rather than addressing the current discomfort.
B. Continue the infusion and reassure the patient.
Continuing the infusion without addressing the patient's discomfort could lead to potential complications, and it is important to prioritize patient comfort and safety. Reassurance alone may not be sufficient if there is an issue with the IV site.
C. Flush the line with 10 mL of normal saline and continue the infusion.
While flushing the line with normal saline is a good practice to ensure patency, it may not resolve the issue if there is ongoing irritation or infiltration at the site. Continuing the infusion without addressing the patient's complaint might lead to further discomfort.
D. Discontinue the IV and restart the IV infusion in a different site.
This is the best action. Discontinuing the IV allows the nurse to assess the current site for signs of infiltration or irritation. Restarting the IV in a different site addresses the immediate issue, ensuring that the medication is delivered safely and effectively.
Correct Answer is ["36"]
Explanation
To calculate the infusion time for an IV of 1,500 mL running at 25 gtt/min. if the drop factor is 15 gtt/mL, we need to use the following formula:
Infusion time (in minutes) = Volume (in mL) x Drop factor (in gtt/mL) / Flow rate (in gtt/min)
Plugging in the given values, we get:
Infusion time = 1,500 x 15 / 25
Infusion time = 900 / 25
Infusion time = 36
Therefore, the infusion time for this IV is 36 minutes.
