A nurse in a clinic is reviewing the home medications of client who has a history of asthma, and who is at the clinic to have a routine annual physical. Which statement made by the patient would indicate a need for further action by the nurse?

A. Edrophonium is used to diagnose myasthenia gravis, a neuromuscular disorder that causes muscle weakness. It is not used to treat the symptoms described in the question.
B. Prednisone is a corticosteroid used to treat various conditions, including autoimmune diseases and allergies. It is not used to treat Parkinson's disease, which is the most likely diagnosis based on the symptoms described.
C. This medication is the gold standard for treating Parkinson's disease, a neurodegenerative disorder that causes tremors, rigidity, bradykinesia (slowed movements), and postural instability. Carbidopa- levodopa helps to increase dopamine levels in the brain, which can improve motor function and reduce symptoms.
D. Riluzole is used to treat amyotrophic lateral sclerosis (ALS), a neurodegenerative disease that affects motor neurons. It is not used to treat Parkinson's disease.

Client's Response to Nitroglycerin Therapy

• Unstable Angina:
o Typically, unstable angina responds well to nitroglycerin. The relief of discomfort after nitroglycerin administration suggests that the chest pain was likely related to unstable angina, as it indicates a reduction in coronary artery spasm or temporary ischemia.
• Myocardial Infarction:
o In an MI, nitroglycerin may help alleviate pain, but it does not address the underlying cause of myocardial injury. The pain relief in an MI is generally more variable and may not be as effective if there is significant myocardial damage.

2. Client's Initial Report of Manifestations

• Unstable Angina:
o The symptoms described (shortness of breath, dizziness, and discomfort in the jaw, neck, and left arm) are consistent with unstable angina, which is characterized by episodes of chest pain or discomfort at rest or with minimal exertion, often associated with transient ischemia.
• Myocardial Infarction:
o These symptoms can also be consistent with MI, especially if they are severe or persistent. However, MI often presents with more intense and prolonged pain, and the discomfort might not always resolve with rest.

3. 12 Lead EKG Report

• Unstable Angina:
o ST depression on an EKG is more commonly associated with unstable angina, which indicates transient ischemia rather than a sustained myocardial injury.
• Myocardial Infarction:
o ST depression indicates ischemia commonly in angina.

4. Troponin Results

• Unstable Angina:
o Troponin levels are typically normal in unstable angina. The client’s troponin I (0.01 ng/mL) and troponin T (0.03 ng/mL) are within the normal range, suggesting no significant myocardial injury. This is consistent with unstable angina.
• Myocardial Infarction:
o Elevated troponin levels are a key marker of myocardial injury. The normal troponin results in this case do not support an MI diagnosis, as elevated troponin levels would be expected in MI.
