The nurse is providing care for a client admitted to rule out a myocardial infarction who is experiencing chest pain while walking to the bathroom. Which action should the nurse implement first?
Obtain a STAT electrocardiogram
Have the client sit down immediately
Assess the client's vital signs
Administer sublingual nitroglycerin
The Correct Answer is B
A. Obtaining an ECG is important but not the first action. The priority is to stop activity, as exertion can worsen myocardial oxygen demand.
B. Having the client sit down immediately is correct. Stopping activity reduces cardiac workload and oxygen demand, preventing further ischemia or infarction.
C. Assessing vital signs is important but should follow stopping activity. Chest pain requires immediate action to reduce cardiac strain.
D. Administering sublingual nitroglycerin is appropriate but should be done after ensuring the client is seated. This prevents hypotension and syncope from occurring while standing.

B. Total Lactate Dehydrogenase (LDH) was historically used but is not specific for MI and has been replaced by troponin testing.
C. Troponin is correct. Cardiac-specific troponins (Troponin I and Troponin T) are the gold standard for detecting myocardial injury. Elevated levels indicate myocardial damage and are crucial for diagnosing MI.
D. Creatinine is important for assessing kidney function but is not a marker for myocardial infarction.
