A patient suddenly complains of new onset chest pain. What is most likely to be ordered by the doctor?

When a patient presents with new onset chest pain, immediate action is crucial because it could signify a serious condition, such as myocardial infarction (heart attack). The combination of medications and interventions that includes morphine, oxygen, nitrates, and aspirin is commonly referred to as MONA.

Morphine is utilized to reduce pain and anxiety, which can help decrease the workload on the heart. Oxygen is administered to ensure that the heart muscle receives enough oxygen, especially if there is any compromised blood flow. Nitrates are effective in dilating blood vessels, improving blood flow to the heart, and alleviating chest pain. Aspirin is given to inhibit platelet aggregation, which helps prevent the formation of blood clots that can further obstruct blood flow.

This approach represents a standard protocol in the acute management of suspected cardiac events, ensuring that both pain is managed and that interventions are in place to protect the patient's heart. It's crucial to act quickly with these measures to improve patient outcomes.

Other options, while they may have some relevance in different contexts, do not address the immediate and potentially life-threatening nature of new onset chest pain as effectively. For example, closely monitoring vital signs is important but does not provide the necessary treatment. Bed rest and reevaluation in
