What does the pharmacotherapy for Parkinson's disease intended to do?
Increase the amount of dopamine and reduce the amount of acetylcholine.
Increase the amount of dopamine and acetylcholine.
Reduce the amount of dopamine and increase the amount of acetylcholine.
Reduce the amount of dopamine and acetylcholine.
The Correct Answer is A
A. Increase the amount of dopamine and reduce the amount of acetylcholine:
This is the correct answer. Parkinson's disease is characterized by a deficiency of dopamine, so medications aim to increase dopamine levels. Additionally, reducing the activity of acetylcholine helps to restore the balance between these neurotransmitters.
B. Increase the amount of dopamine and acetylcholine:
This is not accurate. Increasing both dopamine and acetylcholine would not address the underlying imbalance seen in Parkinson's disease.
C. Reduce the amount of dopamine and increase the amount of acetylcholine:
This is incorrect. Parkinson's disease involves a reduction in dopamine levels, so reducing dopamine further would worsen the symptoms. Additionally, increasing acetylcholine is not the therapeutic goal in Parkinson's disease.
D. Reduce the amount of dopamine and acetylcholine:
This is not the correct approach. Decreasing both dopamine and acetylcholine would exacerbate the symptoms of Parkinson's disease, as the primary issue is the deficiency of dopamine.

Correct Answer is B
Explanation
A. "Continue taking OCPS because phenytoin is not safe during pregnancy."
This statement is not accurate. While it's essential to address pregnancy risk, phenytoin can reduce the effectiveness of oral contraceptives. Women on phenytoin are often advised to use additional contraceptive measures.
B. "You should use a backup method of contraception along with OCPs."
This is the correct response. Phenytoin can accelerate the metabolism of oral contraceptives, potentially reducing their effectiveness. Using a backup method, such as condoms, is recommended to ensure adequate contraception.
C. "You should stop taking OCPs because of drug-drug interactions with phenytoin."
This advice is generally not recommended without consulting the healthcare provider. Abruptly stopping OCPs without an alternative form of contraception can increase the risk of unintended pregnancy.
D. "You should take low-dose aspirin while taking these medications to reduce your risk of stroke."
This statement is not relevant to the situation described. Low-dose aspirin is not typically recommended for contraception, and its use in this context does not address the potential interaction between phenytoin and oral contraceptives.
Correct Answer is ["100"]
Explanation
To calculate the infusion rate for gentamicin, the nurse needs to use the following formula:
infusion rate (mL/h) = volume (mL) x 60 / time (min).
Plugging in the given values, we get: infusion rate (mL/h) = 50 x 60 / 30 = 100.
Therefore, the nurse would program the electronic infusion pump at 100 mL/h.
