A patient with chest pain has ST elevation on ECG and is sweating profusely. Which nursing action has the highest priority?
Appeared in: NORCET 8 Prelims-2025
Explanation
- The patient is showing classic signs of an acute Myocardial Infarction (MI), where the heart muscle is deprived of oxygen.
- The highest priority is to address the imbalance between myocardial oxygen supply and demand, which is a direct threat to life.
- Administering oxygen increases the oxygen supply to the damaged heart muscle, potentially limiting the extent of the infarct.
- Continuous monitoring of vital signs is critical to detect and manage life-threatening complications such as cardiogenic shock or fatal arrhythmias, which are common in the early hours of an MI.
Why Other Options Were Wrong
- Option A: Encouraging ambulation (walking) increases the heart's workload and oxygen demand. This would worsen the myocardial ischemia and could extend the area of heart muscle damage.
- Option B: Dietary changes are a long-term management strategy for coronary artery disease, not an emergency intervention for an acute heart attack.
- Option D: A warm compress is used for musculoskeletal pain. It has no effect on the ischemic pain of a heart attack and applying it would waste critical time, delaying life-saving interventions.

Clinical Relevance
- Nursing practice connection: Use the key finding related to Priority nursing interventions for a patient with acute Myocardial Infarction (MI) to guide bedside assessment, documentation, and the next nursing action.
- In a suspected MI, the nurse's role is to act quickly. The principle of 'time is muscle' means that rapid assessment and intervention are critical to save heart tissue.
- Nurses are responsible for initiating protocols, which often include obtaining IV access, administering oxygen, giving aspirin, and preparing for further treatments like PCI (percutaneous coronary intervention).
- What if the patient's oxygen saturation was 98% on room air? Current guidelines (SRC_4) suggest that supplemental oxygen is not recommended if the patient is not hypoxemic (O2 saturation is normal, e.g., above 90-94%). The priority would then shift to other immediate actions like administering aspirin and nitroglycerin and managing pain, while still monitoring vitals closely.
How to Approach the Question
- First, identify the question type. This is a clinical scenario asking for the highest priority nursing action.
- Analyze the patient's signs and symptoms. Chest pain, ST elevation on ECG, and profuse sweating are hallmark signs of an acute Myocardial Infarction (MI), a life-threatening emergency.
- Apply the ABCs (Airway, Breathing, Circulation) framework to prioritize interventions. The core problem in an MI is compromised circulation and oxygenation to the heart muscle.
- Evaluate each option based on its ability to address the immediate life threat. Administering oxygen supports 'Breathing' and 'Circulation' by improving oxygen delivery to the ischemic myocardium. Monitoring vitals is essential for assessing circulatory stability.
- Eliminate options that are clearly incorrect or harmful. Ambulation is contraindicated, a high-fiber diet is not an emergency action, and a warm compress is ineffective.
- Select the option that provides the most immediate and critical support to the patient's physiological status.
Concept Tested & Keywords
- Concept Tested: Priority nursing interventions for a patient with acute Myocardial Infarction (MI).
- Stem keywords: chest pain, ST elevation, ECG, sweating profusely
- Lead-in keywords: highest priority
- Clinical cues: The combination of chest pain, ST elevation, and diaphoresis strongly indicates a STEMI (ST-Elevation Myocardial Infarction), which is a medical emergency requiring immediate intervention.
