What should you do when called to a restaurant for a 62-year-old male clutching his chest?

When responding to a situation where a 62-year-old male is clutching his chest, the priority is to ensure the patient's safety and perform an adequate assessment while considering the potential for a serious condition such as a heart attack. Applying oxygen and assessing his pulse is crucial because it allows you to gather initial vital information about the patient’s breathing and circulation status.

Administering oxygen can help support the patient's respiratory needs, particularly if he is experiencing chest pain that could indicate a deficiency in oxygenation, such as during an acute myocardial infarction. Assessing the pulse helps you determine the patient's heart rate and rhythm, which are vital indicators of his cardiac status. A thorough assessment includes checking for responsiveness, airway patency, breathing effectiveness, and circulation, which will inform further treatment and interventions.

While aspirin can be beneficial for chest pain associated with heart issues, it should not be given unless you have assessed the patient's condition and ruled out contraindications. Starting CPR would be appropriate only if the patient is unresponsive and not breathing, which is a significant step that follows a complete assessment. Requesting an advanced unit is a valid action, but the first steps must center around ensuring the immediate care of the patient, which includes assessment and oxygen application.
