Final answer:
Steve is exhibiting symptoms that suggest a possible cardiac event, and immediate medical attention is required. Antacids and rest are not appropriate responses. Calling emergency services is the correct action.
Step-by-step explanation:
When a person exhibits severe indigestion and squeezing pain in the chest, along with shortness of breath and profuse sweating, these symptoms may be indicative of a cardiac event such as angina or even a heart attack rather than simple indigestion. Although antacids can neutralize excess stomach acid and relieve symptoms like heartburn, they are not appropriate for the kind of acute, severe symptoms described by Steve. Steve's symptoms match those of chest pain and discomfort associated with inadequate blood flow to the heart, which could potentially be life-threatening.
Therefore, the correct response for Steve would be option A: Call emergency services immediately. This action is crucial as it addresses the possibility of a serious medical condition requiring immediate attention. Advising Steve to take antacids, rest, or ignore the symptoms could be dangerous and would not be appropriate given the severity and nature of his symptoms.
