Correct answer: CGive cautious fluid while preparing for primary intervention

Right-ventricular infarction produces preload-dependent hypotension with raised venous pressure and clear lungs. A cautious fluid bolus may improve filling while urgent reperfusion is arranged. Nitrates, diuretics and excessive positive pressure reduce preload and can precipitate collapse. Primary PCI remains the definitive reperfusion strategy.
