Questions: Which treatment would likely be initiated for a patient who is brought to the emergency department with an acute myocardial infarction (MI)? Select all that apply. One, some, or all responses may be correct. Oxygen Meperidine hydrochloride Ibuprofen Nitrous gas Nitroglycerin

The likely treatments initiated for a patient with an acute myocardial infarction (MI) are:

1. Oxygen: Administering oxygen can help increase the amount of oxygen in the blood, which is crucial for a patient experiencing an MI, as it can help reduce the workload on the heart and limit damage to the heart muscle.

2. Nitroglycerin: This medication is commonly used to treat chest pain (angina) and is often administered during an MI to help dilate the coronary arteries, improve blood flow to the heart muscle, and reduce the heart's workload.

Explanation for each option:

• Oxygen: Correct. Oxygen therapy is often used in the initial management of an MI to ensure adequate oxygenation of the heart tissue.

• Meperidine hydrochloride: Incorrect. Meperidine is an opioid pain medication, but it is not typically used in the treatment of MI. Morphine is more commonly used for pain relief in MI cases.

• Ibuprofen: Incorrect. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) and is not typically used in the acute management of MI due to potential adverse effects on the cardiovascular system.

• Nitrous gas: Incorrect. Nitrous oxide is not used in the treatment of MI. It is primarily used for its anesthetic and analgesic properties in other medical settings.

• Nitroglycerin: Correct. Nitroglycerin is a standard treatment for MI to help relieve chest pain and improve blood flow to the heart.

In summary, the treatments likely initiated for a patient with an acute MI are oxygen and nitroglycerin.
