In a patient with obesity presenting with chest pain, which action is not appropriate?

• A. administer oxygen
• B. increase aspirin dosage
• C. monitor vital signs
• D. provide basic airway support as needed

Answer: (B)

In suspected acute coronary syndrome, giving aspirin helps limit clot formation and improves outcomes, but the dose should be a single loading amount given promptly and then not increased. There’s no added benefit to upping the dosage beyond the standard chewable loading dose, and doing so raises the risk of bleeding. So selecting an action that increases aspirin dosage isn’t appropriate; stick to the recommended single loading dose and proceed with other stabilization steps as needed.

In obesity, this same approach still applies: administer the standard aspirin dose if there are no contraindications (like allergy or active GI bleeding) and ensure you don’t exceed the recommended amount unless directed by a clinician. Alongside aspirin, continue essential stabilization: monitor vital signs to catch deterioration, provide airway support if needed, and administer oxygen only if the patient is hypoxic or has an inadequate oxygen saturation. These steps align with stabilizing a patient with chest pain and potential ACS.
