A client arrives in the emergency department complaining of left-sided substernal chest pain, unrelieved by nitroglycerin. Which of the following is the immediate action of the nurse?
  1. Administration of morphine
  2. Administration of supplemental oxygen
  3. Provide a calm environment with minimal stimulation
  4. Assessment of the heart’s electrical activity through the ECG
Explanation
Answer: B-Administering supplemental oxygen should take priority when caring for a client suspected of myocardial infarction. Oxygen supply to the myocardium is severely inefficient during a myocardial infarction and further delay may result in irreversible damages. The other options are appropriate nursing actions, but they are done after the initiation of oxygen administration.
