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. Bradycardia
Bradycardia is not a common side effect of diphenoxylate with atropine. Atropine, which is included in the combination, has anticholinergic effects that can lead to an increased heart rate (tachycardia), not bradycardia.
B. Fluid retention
Fluid retention is not a common side effect of diphenoxylate with atropine. In fact, the medication is used to treat severe diarrhea, and the goal is to decrease fluid loss associated with diarrhea rather than causing fluid retention.
C. Nervousness and tremors
Nervousness and tremors are not common side effects of diphenoxylate with atropine. Atropine's anticholinergic effects may cause nervousness, but these effects are generally not prominent at therapeutic doses.
D. Respiratory depression
This is the correct choice. Respiratory depression is a potential side effect of diphenoxylate with atropine, particularly if the medication is misused or taken in excessive amounts. Atropine is included in the combination to discourage misuse, as it can cause unpleasant anticholinergic effects.
Correct Answer is ["3"]
Explanation
To calculate the dosage of furosemide (Lasix), a diuretic medication, you need to divide the ordered amount by the tablet strength.
In this case, the ordered amount is 120 mg and the tablet strength is 40 mg.
Therefore, you need to divide 120 by 40, which gives you 3.
This means you would administer 3 tablets of furosemide (Lasix) to the patient.
