A nurse is teaching a patient newly diagnosed with Parkinson’s disease about the pathophysiology of the condition. Which of the following explanations best describes the underlying cause of Parkinson's disease?
Inflammation of the motor cortex leads to decreased coordination and balance
Degeneration of dopamine producing neurons in the substantia nigra of the brain leads to motor dysfunction
A loss of acetylcholine in the brain leads to memory problems and cognitive decline.
Excess production of dopamine in the basal ganglia leads to tremors and muscle rigidity.
The Correct Answer is B
A. Inflammation of the motor cortex leads to decreased coordination and balance. Parkinson’s disease is not caused by inflammation in the motor cortex; it primarily involves the loss of dopamine-producing neurons.
B. Degeneration of dopamine-producing neurons in the substantia nigra of the brain leads to motor dysfunction. Parkinson’s disease is caused by the degeneration of dopamine-producing neurons in the substantia nigra, leading to motor symptoms such as tremors, rigidity, and bradykinesia.
C. A loss of acetylcholine in the brain leads to memory problems and cognitive decline. While a loss of acetylcholine is associated with Alzheimer’s disease, it is not the primary issue in Parkinson’s disease.
D. Excess production of dopamine in the basal ganglia leads to tremors and muscle rigidity. In Parkinson’s disease, there is a decrease, not an excess, in dopamine production, which contributes to motor symptoms.

Correct Answer is D
Explanation
A. Peripheral Artery Disease (PAD). PAD is a chronic condition related to reduced blood flow in peripheral arteries. It is not directly associated with MI complications.
B. Gastroesophageal Reflux Disease (GERD). GERD involves acid reflux and is not related to post-MI complications.
C. Hypertension. While hypertension is a risk factor for MI, it does not directly explain the symptoms of shortness of breath and irregular heartbeats following an MI.
D. Heart Failure. Heart failure is a common post-MI complication, especially if a significant portion of heart muscle is damaged. Symptoms of shortness of breath and irregular heartbeats could indicate left-sided heart failure, where fluid backs up into the lungs, or right-sided failure, which can lead to systemic congestion.
Correct Answer is ["B","C","D","E"]
Explanation
A. Family history. Family history is a non-modifiable risk factor for heart disease, as it is genetic and cannot be changed.
B. Smoking. Smoking is a modifiable risk factor. Quitting smoking can significantly reduce the risk of heart disease.
C. Sedentary Lifestyle. Physical inactivity is a modifiable risk factor. Increasing activity levels can help lower the risk of heart disease.
D. Diabetes. While diabetes itself may be a chronic condition, managing blood sugar through diet, medication, and lifestyle changes can reduce heart disease risk.
E. Hypertension. Hypertension is a modifiable risk factor. Controlling blood pressure through medication, diet, and exercise can reduce heart disease risk.
