Your patient is complaining of substernal burning sensation that radiated into the neck and jaw. He says, "I think it is heartburn, can I get some TUMS?" The proper next step is:

Chest pain manifesting as substernal burning with radiation to the jaw can indicate either gastroesophageal reflux or myocardial infarction. Because the clinical presentation of GERD often mimics acute coronary syndrome, the nurse must prioritize excluding life-threatening cardiovascular events. A systematic assessment is required to ensure hemodynamic stability and appropriate triage. A. Check vital signs and conduct a further assessment of the pain: Collecting objective data on blood pressure, heart rate, and pain characteristics is the highest priority. A 12-lead electrocardiogram is often indicated to differentiate between dyspepsia and cardiac ischemia. This step ensures patient safety before assuming the etiology is benign. B. Give the patient his PRN calcium carbonate tablets (TUMS): Administering an antacid without a full assessment risks masking the symptoms of a developing myocardial infarction. While TUMS may relieve heartburn, it provides no benefit for coronary occlusion. This action ignores the clinical hierarchy of excluding lethal conditions. C. Give the patient morphine for pancreatitis: Morphine administration is inappropriate without a confirmed diagnosis and a provider's order. Pancreatitis typically presents with epigastric pain radiating to the back, not the jaw. Administering narcotics for unassessed chest pain is contraindicated and can cause respiratory depression. D. Tell the patient that you will call the provider and get an order for pantoprazole: Requesting a proton pump inhibitor assumes the pain is purely gastrointestinal without diagnostic evidence. Delaying assessment to obtain a medication order for reflux could result in a missed MI. Assessment must always precede the request for medications.
