Feedback:
Drugs used in Parkinson's disease increase levels of dopamine (levodopa, dopamine agonists, monoamine oxidase MAO inhibitors, COMT inhibitors) or inhibit the actions of acetylcholine (i.e., anticholinergic agents) in the brain. Thus, the drugs help adjust the balance of neurotransmitters.
Answer to Question 2
B
Feedback:
When the student asks the patient, Are you Mr. Jones the patient may nod in agreement, even if that is not his name. Perhaps he misheard, or maybe he wasn't paying attention to the name, or he may just want to be agreeable but this manner of ensuring the right patient receives a medication often results in errors. The student is correct to check the medication name against the medication administration record (MAR) three times to ensure the right drug is administered. The student who checks brand name and generic name is accurate in making sure the correct drug is prepared. Medication should be documented as soon as they are given so this student is also correct.
