A client is admitted to the emergency room with chest pain and a suspected diagnosis of acute myocardial infarction (MI). Which test would the nurse expect the physician to order to make a definitive diagnosis of MI?

Choice A rationale

Administering insulin when the breakfast tray arrives may not provide sufficient time for the insulin to take effect before the client begins eating, potentially leading to hyperglycemia.

Choice B rationale

Administering insulin at 07: is too early and may result in hypoglycemia before the client eats breakfast.

Choice C rationale

Administering insulin at 07: allows sufficient time for the insulin to take effect before the client eats breakfast, helping to maintain appropriate blood glucose levels.

Choice D rationale

Administering insulin 30 minutes after breakfast is too late and could result in hyperglycemia since the client would have already consumed carbohydrates.

Choice A rationale

Radiating pain to the left arm is a classic symptom of a myocardial infarction (MI) due to referred pain from the heart.

Choice B rationale

Shortness of breath can also be associated with MI but is not as specific as radiating pain to the left arm.

Choice C rationale

Headache is not a typical symptom of an MI. It is more commonly associated with other conditions.

Choice D rationale

Nausea and vomiting can occur with an MI but are not as specific as radiating pain to the left arm.
