A nurse is assisting in the plan of care for a client who has a suspected myocardial infarction. Which of the following medications should the nurse plan to administer first?
Correct answer
D
Rationale
Oxygen addresses hypoxia in suspected MI, increasing myocardial oxygen supply to limit damage (normal SpO2 95ÔÇô100%). Morphine relieves pain, nitroglycerin dilates vessels, and aspirin prevents clotting, but oxygen is the priority per MONA protocol (Morphine, Oxygen, Nitroglycerin, Aspirin) when hypoxia is possible.
